A $1 billion telescope that will take pictures 10 times sharper than Hubble’s is now officially under construction

giant magellan telescope gmt observatory astronomy rendering chile gmto corporation 00004

  • Construction crews have broken ground on the Giant Magellan Telescope in Chile.
  • When complete, the telescope will have a light-collecting area about 80 feet in diameter — nearly the area of a basketball court.
  • GMT’s photos will be about 10 times sharper than those of NASA’s Hubble Space Telescope.
  • Laser-based optics will help the $1-billion telescope "sniff" the atmospheres of potentially habitable exoplanets.

In astronomy, cutting-edge technology often begins with a bunch of bulldozers, busted rocks, and dump trucks.

So it goes with the Giant Magellan Telescope (GMT), which will the world’s largest and most powerful when it sees "first light" in 2024. Astronomers hope to use the huge observatory to study the ancient universe and look for signs of alien life.

Construction crews atop a Chilean mountain range broke ground for the $1 billion project on Tuesday. The final device will weigh more than 2 million lbs, so workers are now punching a 23-feet-deep hole in bedrock that they’ll eventually fill with concrete to support GMT’s enormous weight.

"It will be supported by a 1,000 ton steel telescope structure that will be housed inside a rotating enclosure that will measure 22 stories tall and 56 meters wide," a representative for GMT told Business Insider in an email.

To help probe the universe, GMT will eventually have seven 27-feet-wide mirrors, each weighing close to 20 tons. Together their light-collecting area will be about the size of a basketball court.

The telescope will also use laser-based "adaptive optics" to measure distortion caused by Earth’s atmosphere, correct for that interference, and produce crisper and clearer pictures.

"The GMT mirrors will collect more light than any telescope ever built and the resolution will be the best ever achieved," the project claims on its website.

One estimate suggests the images will be up to 10 times more resolute than those of NASA’s Hubble Space Telescope.

What the Giant Magellan Telescope may discover

The Giant Magellan Telescope is geared toward studying galaxies in the deep universe, but it could play a pivotal role in answering whether or not life on Earth is alone in the universe — or at least refine the likelihood of that possibility.

GMT will follow in the footsteps of NASA’s Kepler space mission, launched in 2009, which discovered thousands of new worlds. About 50 of those are Earth-size and may be cozy enough to support alien life.

But Kepler probed deep and narrow sections of the night sky. NASA’s follow-on space mission, called the Transiting Exoplanet Survey Satellite (TESS), is now scanning 85% of the entire sky for worlds within about 200 light-years of our own (a relative stone’s throw in space). TESS is only equipped to detect possible exoplanets, though, not study them in detail.

Another upcoming NASA space mission, called the James Webb Space Telescope (JWST), may be powerful enough to sample light from an exoplanet’s atmosphere after it launches, perhaps in 2021. Such measurements could help verify if an Earth-size planet has signs of biology and perhaps even breathable air.

However, JWST may not be big enough to take detailed measurements of an Earth-size planet. This is where GMT — expected to be about 14 times as large — could excel. Here’s how it compares to JWST and other planned and current astronomical observatories:

With its full resolving power, GMT might be able to "sniff" alien atmospheres.

"As a planet passes in front of its star, a large telescope on the ground, like the GMT, can use spectra to search for the fingerprints of molecules in the planetary atmosphere," Patrick McCarthy, a leader of the project, previously told Business Insider.

Spectra refers to the blend of colors in starlight. When that light passes through a planet’s atmosphere, chemicals absorb and remit certain parts — leaving a smoking-gun pattern of their presence.

A mix of oxygen and methane gases similar to that of Earth’s atmosphere, for example, could be a "fingerprint" of life’s presence on an exoplanet.

McCarthy also said large and powerful new telescopes like GMT might be able to deduce weather systems and surface features of planets located trillions of miles away.

If Russian billionaire Yuri Milner has his way, we might even send tiny, high-speed spacecraft past the most promising planets in the next few decades.

Tomu is a fingernail-sized computer that is easy to swallow

Standard

I’m a huge fan of single board computers, especially if they’re small enough to swallow. That’s why I like the Tomu. This teeny-tiny ARM processor essentially interfaces with your computer via the USB port and contains two LEDs and two buttons. Once it’s plugged in the little computer can simulate a hard drive or mouse, send MIDI data, and even blink quickly.

The Tomu runs the Silicon Labs Happy Gecko EFM32HG309 and can also act as a Universal 2nd Factor security token. It is completely open source and all the code is on their GitHub.

I bought one for $30 and messed with it for a few hours. The programs are very simple and you can load in various tools including a clever little mouse mover – maybe to simulate mouse usage for an app – and a little app that blinks the lights quickly. Otherwise you can use it to turn your USB hub into an on-off switch for your computer. It’s definitely not a fully fledged computer – there are limited I/O options, obviously – but it’s a cute little tool for those who want to do a little open source computing.

One problem? It’s really, really small. I’d do more work on mine but I already lost it while I was clearing off a desk so I could see it better. So it goes.

 I’m a Cyclist That Finally Needs a Car! What Should I Buy?

Standard
1996 Citroen Berlingo Coupe de Plage pictured. Photo: Citroen

Patrick loves cars but has never really needed one. He has gotten by just fine with using his bike. Now he has a new job and a longer commute through the DC traffic hellscape. If he wants to survive he is going to need four wheels and doors. What car should he buy?

(Welcome back to What Car Should You Buy? Where we give real people real advice about buying cars. Do you want us to help you find a car? Submit your story on our form.)

Here is the scenario –

Longtime listener, first time caller here. I love Jalopnik even though I’m a cyclist; I have a license but I’ve never even owned a car. City kid.

Next month, however, all of that that changes. I got a new job just 12 miles away! While our traffic is awful, our public transportation is worse, leading me to you all. At 28, I am going to buy my first car. Gulp.

This is, first and foremost, a commuter. Probably 150 miles a week, give or take. It’s not a long commute but it’s a slow one, laden with potholes and speed cameras; it’ll take up to an hour ~each way~. I live in the middle of DC, which means I’ll be parallel parking on the street at least once a day, often in the dark. Hopefully, this will be comfortable for all that. I am also 6'5, so the tiniest of cars are out of the question.

Being good on gas would be nice, being reliable is better. I’ve been conditioned not to drive fast by living here and I can’t drive a manual so a slow car is quite alright. It’s got to be able to get up a hill, though, because I live on a steep one.

If it sounds like I’m dreading this, I kinda am. DC’s not nice to drivers. But the right car could improve my perception a little here. (I think.)

I’d like something I could mount a bike rack to ~and~ something I can carry art/art supplies in. (Also open to carrying bikes inside.)

I’m a painter, semi-professionally, and like to work at a large-ish scale (think 2×4' and 3×4' canvases.) I don’t carry a dozen at once, but being able to carry a few paintings comfortably would be a nice bonus. Sometimes I have to deliver work out of town or take work to show and it’s never fun to measure and test rentals for interior space.

Something with a durable cargo area (think Honda Element status) would be good, because I’ll inevitably spill paint inside.

As for budget, I can spend up to $40,000.

Quick Facts:

Budget: up to $40,000

Daily Driver: Yes

Location: Washington DC metro

Wants: Durable, good storage, easy to park

Doesn’t want: Too much fancy tech

Expert 1: Tom McParland – You Said You Wanted Simple

While you are a guy that can appreciate a nice ride, it seems that your true passions are cycling and painting. Therefore if this is a car you are buying more out of necessity than desire, you should get something that best compliments those two activities. Normally, I’m the one advocating for getting the nicest ride you can afford, but in this case, I think you should bank a good chunk of that $40,000 budget because you can get something that fulfills your needs for much less.

Advertisement

What you need is a Ford Transit Connect, but not the one that is a van for passengers, the other one that is more like a commercial vehicle. They aren’t fancy on the inside, and you said you didn’t want or need a lot of tech, but they hold a ton of stuff. You could hold several portfolios worth of paintings or have enough bikes for a Tour de France team. They also get pretty decent gas mileage at up to 27 MPG on the highway. Despite the fact that these are a “van” they are small enough to easily parallel park.

And here is the best news, a nicely equipped XLT trim will set you back less than $30,000. That’s plenty of cash leftover for expensive bikes and/or paint supplies. These “commercial” style vans usually are only found in white which is a bit boring, but you are an artist, use that as a canvas to make your fan look awesome.

Expert 2: Jason Torchinsky – You’re Artist, You Can Pull This Off

I’m desperately trying not to always be a shill for Nissan’s long-gone series of creative, limited run cars known as the Pike cars, but I’ll be damned if you don’t happen to have the perfect set of criteria for one: the S-Cargo.

Advertisement

Tom’s basically right there that a small, utilitarian delivery van is the right idea; I’m partial to the first-gen Ford Transit myself, but I think that, as an artist, you can get away with something a little more fun, a little more daring. A little more S-Cargo.

That’s right. Your situation is perfect for Nissan’s snail-themed fun little delivery van, the S-Cargo. It’s great on gas, has an automatic, not really fast (but adequate enough—it has a 1.5-liter engine, the biggest of all the Pike cars), is small enough to be easy to parallel park pretty much anywhere in DC, and yet is a genuine delivery van, with plenty of room for bikes and tall canvases and all manner of stuff.

Plus, look at the damn thing: it’s that most elusive of automotive wonders, a non-boring cargo van. It’s silly and fun and practical all at once. There’s plenty of blank canvas on the sides if you decide to paint a mural there (I mean, you should) and even if you do nothing it looks like nothing else on the road.

Advertisement

The interior is roomy and surprisingly comfortable (I’ve checked) for your long, dull commute, and the S-Cargo will de-dull that trip by 70 percent, minimum, if my math is right.

There’s even one available not far from you, and it’s about a quarter of what you’re willing to spend: $9,900. Most had dark gray trim, but this one has yellow, which I kind of like. It even has a canvas sunroof for when you need to see some sky on your long-ass commute! If you prefer gray, there’s options for that, too.

Man, I actually think this one makes real sense! Weird.

Expert 3: Kristen Lee – Embrace the Right Angles

You know what you need for the crucible of bad traffic? Something large and in charge. Like the Ford Flex. You sit up high so you can see over the jam and people will have no trouble missing you.

Advertisement

The Ford Flex was always rather special to me because in a sea of SUVs masquerading as sporty cars, the Flex rejected that idea wholly and simply looked like a box on wheels. Its simple design means that it will age well and, frankly, not a whole lot of people have them. Obviously, that led to Ford killing off the Flex in 2016, but that only makes them all the more appealing. You’d be buying novelty as well as utility!

With its seats folded down, the back of the Flex is room as all hell. Throw down some WeatherTech mats to protect your upholstery from paints and you’re all set!

Here’s a 2017 Flex for just $27,830. And it’s got all-wheel drive for bad weather.

Expert 4: Ryan Felton – Buy Something Fun and Weird

You don’t want to fuss around with tech and need something sturdy? Something with a lot of space? Look, man, forget what these other busters pitched. I’m telling you to get Every. Yes, that’s the name of this silly van from Suzuki. Every! And it looks like it fits everything you need.

Advertisement

This particular 2008 model from Duncan Imports looks like it has some after-market work done—obviously, for one thing, the VW body stands out. But it has good specs! Only 40,000 miles on it. A brown exterior with a tan interior. Surely, D.C. drivers will stay the fuck off your back in this thing.

Plus, it’s well within your budget.

Of course, it’s not legal for full-speed road use as it’s not legal within the 25 Year Rule, but there are plenty of other options like a 1993 Mitsubishi Delica for $18k that’s good for getting to any trailhead, no matter how far.

Netflix has tons of hidden categories — here’s how to see them

Standard

Netflix hidden categories are the secret to better binging, friends. 

The vast amount of content on Netflix can get pretty unwieldy. Luckily, there’s a secret, better way to browse the swaths of mediocre titles on the streaming service to get to what you’re really looking for.

Netflix has a master list of hidden categories that go far beyond the usual Action, Drama, Sci-Fi, and the like. First discovered by the blog What’s On Netflix, anyone can access them by simply typing specific URLs into a browser. Each URL has the format:

http://www.netflix.com/browse/genre/###

…where the “###” is where you put the code that relates to the particular Netflix category you’re looking for. For example, 35800 is steamy romantic movies, 11140 is supernatural thrillers, and 67879 is Korean TV shows. You can check out the complete list below.

“We categorize our content into thousands of subgenres to help match the right content to the right member based on their viewing history,” Netflix spokesperson Marlee Tart told Mashable via email.

Some of these categories don’t even come up in a Netflix search. While searching “Korean TV Shows” brings up the same list that appears at the category URL, searching “Classic War Movies” doesn’t bring up up any results. Some categories appear to be only used for suggestion purposes.

Tart didn’t share the exact number of genres they use to curate their movies and TV shows, but she says it changes often.

Scientists are zeroing in on the right amount of carbs to eat for a long life — here’s how much should be in your diet

Standard

eating bread bagel breakfast

  • New evidence from a long-term study suggests that neither high-carb nor low-carb diets are necessarily great for your health. 
  • Scientists studied more than 15,000 people in the US and another 400,000-plus around the world, and found that getting about 50-55% of a day’s energy from carbohydrates might be ideal
  • People who ate significantly more or less carbs than that were more likely to die, according to the study.

 
For years, dieters have had to deal with a lot of conflicting advice on how to eat.

First, fat was the bad guy. Then it was considered ideal to avoid sugar and go low-carb.

Lately, dieters trying the trendy ketogenic diet have discovered that if they replace carbs with fat, they can trick their bodies into a natural starvation mode and lose weight, while still enjoying bacon and slurping heavy cream. 

But a new, long-term study published Thursday in The Lancet suggests there may be a winning formula for the amount of carbohydrates to eat every day. It relies on some very unsexy, old advice: everything in moderation. 

Lead researcher Sara Seidelmann, a cardiologist and nutrition researcher at Brigham and Women’s Hospital in Boston, told Business Insider that her results suggested a diet "rich in plant based whole foods such as vegetables, whole grains, legumes, and nuts is associated with healthy aging." 

That usually means about half of the calories you eat in a day should come from carbohydrates.

A Goldilocks rule for carbs

For the study, Seidelmann looked at the diets of more than 15,400 adults in the US and another 432,000 people in more than 20 countries around the world. She and her team of researchers analyzed that information in relation to how long the study participants lived.

They found that people who ate a moderate amount of carbohydrates — around half of their daily calories — tended to live the longest.

Conversely, people who derived more than 70% of their energy from carbs or got less than 40% of their daily calories from carbohydrates were more likely to die than people who ate something in between.

It’s a kind of Goldilocks finding: we should eat not too many carbs, not too few, but just the right amount. 

On one end of the spectrum are people who suffer health consequences from eating too many carbs, like in some lower-income countries where people tend to rely on white rice for sustenance without much else on their plate. 

On the other end are people who consume to few carbs. Surprisingly, the group at highest risk of death in the US study were those who didn’t eat carbs, since those people tended to replace carb-heavy foods with animal fats and proteins: "beef, pork, lamb, chicken, and cheese," as Seidelmann put it.

"Clearly, filling your plate with those things increased mortality," she said. 

In fact, the researchers concluded that a 50-year-old who eats within the 50-55% carbs margin could expect to live for another 33.1 years, while someone the same age who gets just 30% of their calories from carbs would be expected to live roughly 29.1 more years. 

The important part is getting as many whole, healthful foods onto your plate as possible

There is a way to do a low-carb diet and age well: people who ate small amounts of carbohydrates but more plant-based proteins like veggies, beans, and nuts were found to be less likely to die and tended to live to a ripe old age. 

This might be because eating large amounts of animal fat and protein but few fresh plant-based foods can increase inflammation in the body.

"Try to make choices that fill your plate with plants," Seidelmann said.

She agrees there’s a short-term link between low-carb diets and weight loss, but cautions that diets like keto and Atkins might not be great long-term strategies. 

"There’s absolutely nothing more important for our health than what we eat each and every day," she said. "I really would like individuals to realize the power that they have over their own health," she said.

How To Install TensorFlow GPU (With Detailed Steps)

Standard

Install TensorFlow GPU

By Varun Divakar

When I started working on Deep Learning (DL) models, I found that the amount of time needed to train these models on a CPU was too high and it hinders your research work if you are creating multiple models in a day. Later I heard about the superior performance of the GPUs, so I decided to get one for myself. One of the basic problems that I initially faced was the installation of TensorFlow GPU.

After a lot of trouble and a burnt motherboard (not due to TensorFlow), I learnt how to do it. A few days earlier I spoke to someone who was facing a similar issue, so I thought I might help people who are stuck in a similar situation, by writing down the steps that I followed to get it working.

Installing Tensorflow on WindowsClick To Tweet

In this blog, we will understand how to install tensorflow on a Nvidia GPU system. Before we do that, let us look at the various steps involved in the process of installation:

  1. Uninstall Nvidia
  2. Install Visual Studio
  3. Install CUDA
  4. Install cuDNN
  5. Install Anaconda
  6. Install TensorFlow-GPU
  7. Install Keras

 

1. Uninstall Nvidia

This may not look like a necessary step, but believe me, it will save you a lot of trouble if there are compatibility issues between your current driver and the CUDA. Once you login to your system, go to the control panel, and then to the ‘Uninstall a program’ link. Then scroll below to the section with programs that have been published by the NVIDIA corporation.

Unistall Nvidia1

Here, you uninstall all the NVIDIA programs. Do not worry if you have some drivers, they can be updated later once you finish the setup.

Once you have removed all the programs, go to the C drive and check all the program files folders and delete any NVIDIA folders in them.

 

 

2. Install Visual Studio

In the next step, we will install the visual studio community from here

Visual studio1

Here, make sure that you select the community option.

Visual studio2

Once you have downloaded the Visual Studio, follow the setup process and complete the installation.

 

3. Install CUDA

This is a tricky step, and before you go ahead and install the latest version of CUDA (which is what I initially did), check the version of CUDA that is supported by the latest TensorFlow, by using this link.

I have a windows based system, so the corresponding link shows me that the latest supported version of CUDA is 9.0 and its corresponding cuDNN version is 7.

Install cuda1

As it goes without saying, to install TensorFlow GPU you need to have an actual GPU in your system. So please check if you have a GPU on your system and if you do have it, check if it is a compatible version using the third link in the above screenshot.

Once you are certain that your GPU is compatible, download the CUDA Toolkit 9.0 from this link.

Please choose your OS, architecture (CPU type of the platform) and version of the OS correctly. Then click on the exe(local) button,

Now download the base installer and all the available patches along with it.

Install cuda2

Once the download is complete, install the base installer first followed by the patches starting from Patch 1 to Patch 4.

If you face any issue during installation, please check the forums using this link.

 

4. Install cuDNN

Once your installation is completed, you can download the cuDNN files. To do this, go to this link.

Here to download the required files, you need to have a developer’s login. So, please go ahead and create your login if you do not have one.

Once you create your login and agree to the terms and conditions, visit the archived cuDNN files using this link.

And click on the cuDNN version 7.0 for CUDA 9.0

Install cuDNN1

Then choose the appropriate OS option for your system.

Install cuDNN2

This will download a zip file on to your system. Once you unzip the file, you will see three folders in it: bin, include and lib. Extract these three files onto your desktop.

Install cuDNN3

Once you have extracted them. Go to the C drive, there you will find a folder named NVIDIA GPU Computing Toolkit. Inside this, you will find a folder named CUDA which has a folder named v9.0. In this folder, you can see that you have the same three folders: bin, include and lib. Copy the contents of the bin folder on your desktop to the bin folder in the v9.0 folder. Similarly, transfer the contents of the include and lib folders.

Once you are done with the transfer of the contents, go to the start menu and search for ”edit the environment variables”. Click on the search result and open the System Properties window and within it open the Advanced tab.

Install cuDNN4

Now click on the ‘Environment Variables’,

Install cuDNN5

and under System Variables look for PATH, and select it and then click edit.

Add the following two paths to the path variable:

  • C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin
  • C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\libnvvp

Install cuDNN6

Once you are done with this, you can download Anaconda, and if you already have it, then create a Python 3.5 environment in it.

 

5. Install Anaconda

To install Anaconda on your system, visit this link.

Here choose your OS and the Python 3.6 version, then click on download. Follow the instructions in the setup manager and complete the installation process.

Once you have completed the installation of Anaconda. Create a python 3.5 environment using the following command in the terminal or anaconda prompt.

conda create -n tensorflow python=3.5

Once the environment is created, activate it using the following command in the terminal or anaconda prompt:

activate tensorflow

 

6. Install TensorFlow- GPU

Once you have the environment ready, you can install the tensorflow GPU using the following command in the terminal or anaconda prompt:

pip install --ignore-installed --upgrade tensorflow-gpu

You will need to specify the version of tensorflow-gpu, if you are using a different version of CUDA and cuDNN than what is shown in this blog. The above line installs the latest version of tensorflow by default. If you have any issues while installing tensorflow, please check this link.

 

7. Install Keras

Once the tensorflow is installed, you can install Keras. Using the following command:

pip install keras

Once the installation of keras is successfully completed, you can verify it by running the following command on Spyder IDE or Jupyter notebook:

import keras

Some people might face an issue with the msg package. In case you do, you can install it using the following command

conda install -c anaconda msgpack-python

 

I hope you have successfully installed the tensorflow- gpu on your system.

In this article, we have covered many important aspects like how to install Anaconda, how to install tensorflow, how to install keras, by installing tensorflow gpu on windows. We started by uninstalling the Nvidia GPU system and progressed to learning how to install tensorflow gpu.
