Boy do I have the movie for you.
I get what you are saying but I was referring to how this one was a bunch of restored and even some unreleased footage from NASA archives
Oh I was just being a dick
Einstein cross. The four blue spots are the same galaxy 20000 light years away. Gravitational lensing.
Badass. Things like this remind me how stupid I am.
And it's like 5 pixels across in billions of pixels and somehow they still find it.
These size comparisons always fascinate me
That’s really cool.
Liked without watching simply for B holes on the key
Never heard of this type of star before
Was expecting dickbutt.
I don't see the flag
Mars is getting a helicopter.
maybe discussed elsewhere, India did something really fucking stupid and selfish
We Might Be About to See the First Ever Photo of a Black Hole
An announcement next week by an international collaboration might contain the first-ever photo of a black hole's event horizon.

Next week, a collection of countries around the world are going to make a big announcement, and no one is sure exactly what it’s going to be. However, there are some possibilities, and the most exciting one is that they are about to reveal the first-ever photograph of the event horizon of a black hole.
Taking a photo of a black hole is not an easy task. Not only are black holes famous for not letting any light escape, even the nearest known black holes are very far away. The specific black hole astronomers wanted to photograph, Sagittarius A*, lies at the center of our galaxy 25,000 light-years away.
The international Event Horizon Telescope project announced its plan to photograph Sagittarius A* back in 2017, and they enlisted some of the world’s biggest telescopes to help out. The researchers used half a dozen radio telescopes, including the ALMA telescope in Chile and the James Clerk Maxwell telescope in Hawaii, to stare at Sagittarius A* over the past two years.
And while a picture of the black hole itself is impossible, the EHT astronomers were really aiming at the next best thing: the event horizon, the border of the black hole beyond which not even light can escape. At the event horizon, gravity is so strong that light will orbit the black hole like planets orbit stars, and our telescopes should be able to pick that up.
But even with multiple telescopes pointing at Sagittarius A* for the better part of two years, imaging a black hole is not easy. The event horizon of a black hole is one of the most volatile places in the universe, and any black hole worth the name is going to be surrounded by immense amounts of dust, gas, and other stars. These are all obstacles to our telescopes, and only sheer ingenuity on the part of the EHT's astronomers will allow us to pierce that veil.
Next week, we’ll finally get to experience the first results from this mission. There's no way to know what to expect, although of course everyone is hoping for a really good black hole photo. Regardless of the details, however, next Wednesday we’ll almost certainly be seeing something no human has ever seen before.
It's a busy week for SpaceX
Starship hopper should be getting its first single Raptor engine static fire today or tomorrow between 2 and 10 PM: https://www.themonitor.com/2019/04/02/spacex-testing-closures-extended/
Falcon Heavy should get a static fire of all 27 Merlin engines on Thursday morning ahead of its first commercial launch that's planned for Sunday evening: https://spaceflightnow.com/2019/04/01/falcon-heavy-arabsat-6a-preparations/
Unrelated, at an employee townhall meeting a NASA admin discussed using a Falcon Heavy rocket to get the Orion spacecraft into orbit since Pence wants us on the Moon by 2024 and there's no way that the SLS will be ready by then: https://arstechnica.com/science/201...on-heavy-rocket-could-fly-humans-to-the-moon/
What a bunch of fucking idiots.
I read somewhere that those anti satellite weapons have the potential to cause a cascade reaction that could encompass the entire earth in an impenetrable wall of debris.
Sounds like the GOP's immigration proposal when alien life is discovered
Well on the bright side that may protect us from aliens
Pretty sure this is a good link for the reveal.
We found Sauron!
So that's absolutely a portal to another dimension right?
It’s beautiful even at 6.5 billion times our sun’s mass. Yikes.
This guy explained it pretty well.
Dude naiked it too
That’s pretty much exactly the take I would expect from barstool
"Bro, come on why isn't that shit in HD?"
Like, that's not even a good picture dude. Is this Windows 95? Bro you can't even take a better picture than that?
“We already had a good picture, it was called interstellar, why doesn’t it look like that”
So, I'm guessing the "light" in the pic is the superheated matter in the accretion disk?
Pretty god damn amazing day for science.
I am not a scientist so I ask this out of curiosity only. It seems like in the last 10-20 years we've become very good at finding and viewing things. Our ability to send back images of distant stars, galaxies, and now black holes has been amazing. But practically speaking, what has all of this accomplished. Now we can see what we already knew was there, but so what? We got these great images of Saturn and Pluto but besides it being cool, what good does it do? I understand the potential practical implications of the Space X stuff and being able to land a rocket after use, but while cool, what does sending a blurry image of a black hole we know exists do to advance anything?
The picture of the black hole verified the math. As far as practical applications of space exploration (via person or photograph), I mean, there's tons of stuff that comes out of it that's sort of tangential. Some of the biggest discoveries or developments in history came as a result of innovation for space.
The interstellar one is pretty damn close. Who was it that helped nolan make that in the movie?
Do we ever go anywhere meaningfully without exploring ahead first? Not to say it's viable to set up a human colony on saturn/pluto but it's not just the images, we're getting a lot of good data on the planets and what this could mean about what we find in other solar systems at least.
Yes there’s a video out there of Thorne running all the math and simulations to come up with the look of a black hole for the movie. I’ll try and find it later.
These kinds of videos always make me wonder about our sense of scale. Could there be some living being/organism/whatever that's massive, like the size of earth or our solar system?
Also that the way we perceive things is through our senses, and what else we are not "seeing" because we do not have the ability to perceive it. Some of that is detectable, like radiation and gravity, but is there more going on that we are not aware of?
On the flip side...
