NASA released incredible new animations of a star that exploded with the energy of 100 million suns

New animations released by NASA are recasting a groundbreaking astronomical moment in a whole new light.

On February 24, 1987, astronomers Oscar Dhalde and Ian Shelton witnessed an incredible sight atop a Chilean mountain: a new star in the night sky. Soon, however, they realized it was not a star’s birth; rather, it was a blue supergiant meeting its doom.

In that moment, the fusion-powered core of the star — previously called Sanduleak −69° 202 — began to falter. Most astronomers agree the blast happened because the star’s core ran low on high-energy fuel, while some believe another star merged with the blue supergiant to trigger the blast.

Whatever the cause, the star collapsed under its own gravity, exploded, spewed its radioactive guts all over space, and generated the power of 100 million suns in the process. We now call the object Supernova 1987A, or SN 1987A.

supernova sn 1987a xray visible infrared nasa stsci h p1708b f 3000x2500It was not only the brightest supernova seen for hundreds of years, but also the first time astronomers recorded such an event with modern, high-tech instruments.

“Supernova 1987A became one of the best opportunities ever for astronomers to study the phases before, during, and after the death of a star,” a video produced by NASA’s Chandra X-ray Observatory team said.

The data has provided lots clues about supernovas, including how they forge new elements that life needs to evolve and distribute them around the universe.

NASA recently commemorated the supernova’s anniversary with a bunch of new multimedia, and a few of the images and animations caught our eye.

Zooming in on a supernova’s leftovers

This animation gives you a sense of where in the night sky (and just how far away) SN 1987A is located.

The remnants lurk inside the Large Magellanic Cloud, a dwarf galaxy that trails the Milky Way some 168,000 light-years from Earth.

This vast distance means the explosion technically happened 168,000 years in the past, at least relative to where we live. It took that long for the light from the blast to reach us.

Ring of radioactive fire

About once a month over the course of more than 20 years, the Hubble space telescope has photographed SN 1987A and its traveling shock wave. Astronomers continue to compile these images into animations to watch the system evolve.

Starting around the year 2000, they saw the shockwave begin slamming into a 1-light-year-wide ring of gas and dust that the star threw off before its death, creating a brilliant, bubbling glow.

Researchers now believe the high-speed blast wave is leaving the field of gas and dust, marking the beginning of a major change in its evolution, according to a pre-print study posted to

3D model of a disaster

This new animation is a computer simulation that used decades of observations to map SN 1987A’s explosion in three dimensions.

The model, described in a pre-print study also posted to arXiv, can also fast-forward SN 1987A’s evolution years into the future.

The first major game on Nintendo's new console is one of the best games I've played in years

The biggest video game company in the world, Nintendo, is on the verge of releasing a new video game console. It’s called the Nintendo Switch, and it arrives on March 3 for $299.

The gimmick with the Switch is simple: It’s a portable game console and a home game console, all at once.

Nintendo Switch

But a neat gimmick isn’t enough to sell a game console, and Nintendo knows it. For a console to sell, it needs games. To that end, Nintendo has an elfin ace up its sleeve in “The Legend of Zelda: Breath of the Wild.” 

The game is gorgeous, massive, and arriving alongside the Switch on March 3.

The Legend of Zelda: Breath of the Wild

So, is it any good? Good news: It’s fantastic. I play a lot of games — it’s my job, even! — and “The Legend of Zelda: Breath of the Wild” is one of the best games I’ve played in years. It’s hard to be too hyperbolic about what a tremendous game “Breath of the Wild” is. Here’s why.

REVIEW: Nintendo’s new game console is a fast, competent piece of hardware without enough software

DON’T MISS: Forget about that ‘Super Mario’ game on your iPhone — this is the new Mario game you’re looking for

WARNING: If you want nothing spoiled in “The Legend of Zelda: Breath of the Wild,” this is not the review for you. There are minor spoilers below.

The story of “The Legend of Zelda: Breath of the Wild” is a story 10,000 years in the making. Link, the game’s main character, wakes up in a tomb of sorts, where he’s been sleeping for 100 years.

Much of the setup for “Breath of the Wild” happened 100 years in the past. The game supposes that you (Link) and Princess Zelda — the long-time heroine of the series — failed in a major battle against long-time antagonist Ganon.

There's a way to get YouTube's new cable TV competitor for $12 a month — with a little planning

youtube TV

On Tuesday, YouTube debuted YouTube TV, its new service that competes with cable and satellite television by offering you a package of channels delivered over the internet — to your smart TV, phone, or laptop, and so on.

YouTube TV is offering what’s called a “skinny bundle,” in this case a package of around 40 channels built around deals with the major broadcast networks (CBS, ABC, NBC, and Fox) and their affiliate stations. There are some big holes, particularly around YouTube not having Time Warner content like CNN, TNT, and HBO. With any smaller package, there are tradeoffs, however YouTube has made sports a focus.

“YouTube TV includes major sports networks like ESPN and regional sports networks like Fox Sports Networks and Comcast SportsNet, so you can watch your favorite NBA or MLB teams,” YouTube said in a press release. “We’ve also partnered with local TV stations, so you’ll also get sports and local news based on where you live.”

The package costs $35 dollars a month, but with a little planning, you can get access to it for about $12 a month. That’s because YouTube TV lets you have three simultaneous streams going at once (most of its competitors offer only two), and lets you have up to six accounts connected. If you want to save money, it’s easy to split that $35 dollar cost between three people, all three of whom can be watching different shows at the same time.

YouTube has been explicit about targeting millennials with this offering. “Millennials love great TV content, but they don’t want to watch it in the traditional setting,” YouTube CEO Susan Wojcicki said at YouTube TV’s launch event in LA on Tuesday. And many millennials don’t yet have to worry about things like their teenage kids all wanting to watch different shows in their rooms.

YouTube TV has a few big caveats and programming holes, but if you are a cord-never or cord-cutter looking to get back into the TV ecosystem, finding two friends and paying $12 a month might be a lot more palatable.

The service will be available in the next few months.
