Groundbreaking discovery confirms existence of orbiting supermassive black holes

What are they orbiting though?

Each other. Oh. They're roughly 750 million light years from Earth, in the galaxy named 0402+379. These babies have an orbital period of 24,000 years so we haven't observed them doing much of anything yet. Combined, they share a mass of about 15 billion times that of the sun.

But it's pretty cool to see the technical ability here. Why is this impressive?

"If you imagine a snail on the recently-discovered Earth-like planet orbiting Proxima Centauri - 4.243 light years away - moving at 1 cm a second, that's the angular motion we're resolving here," said Roger W. Romani, professor of physics at Stanford University and member of the research team.

"For a long time, we've been looking into space to try and find a pair of these supermassive black holes orbiting as a result of two galaxies merging," said Taylor. "Even though we've theorized that this should be happening, nobody had ever seen it until now."

Bansal and Taylor say the research could also teach us a lot about the universe, where galaxies come from and where they're going.

Jesus fuck, 750 million light years away and we're studying this and understanding what's going down, in literally a galaxy far far away. How in fuck..

Edit: And yes, the response I've received 800 quadrillion times, it is also, a long time ago

Don't you fucking dare correct the grammar in this post

Light refraction onto mirrors and stuff.

WHAT I WANNA KNOW IS..... what made the super assive black holes?

2 Million Free Eclipse Glasses Coming to US Libraries

2 Million Free Eclipse Glasses Coming to US Libraries

I already bought a dozen on eBay....they're awesome to just look at the sun....I give everybody a try and they're always pretty amazed. The only thing you can see is the sun. Very very cool and I think it's great libraries will have free ones, aren't libraries the best 😊

Edit: just search 'solar eclipse glasses' or follow a link from a kind redditor below. It was 10 for $13.50 all sorts of ISO and CE certified numbers and stuff in the item description....and they have American flags on them.

The glasses do say not to look at the sun for longer than 3 minutes but that's a long ass time if you really try and actually getting to see that big ball of fire up there is really cool...these are going to be a year round type of thing for me and not just for the eclipse

Also I have no idea what the deleted comments are about

My local Reddit ran that same story

I'm totally considering a 15 hour each way road trip to see 100%

My local fox news ran a story about millennials being the most likely to go to a library or some shit

The first ever image of the surface of another star, Betelgeuse, has been captured by ALMA

This picture is made in sub-millimeter wavelengths. On the other hand that picture is still my favourite one of the Betelgeuse, made in infrared. It's quite an incredible star.

Betelguese is a lot bigger than Alpha Centauri, so while Alpha Centauri is 160 times closer than Betelguese, Betelguese is 1400 times larger, making imaging its surface much easier.

God, I hope that goes supernova in my lifetime.

Edit: If one more person replies or messages me that if it went supernova today I wouldn't see it for 6...

Quite incredible actually. The SDO space telescope captured unbelievable stuff. Stuff from 2 weeks ago.

Note worthy also the 2012 Venus transit which was recorded by SDO.

ISS construction animation timelapse

This is so badass

I love how they reutilized the first solar panels after expanding it, so methodical.

You can see it often! They have a website to see when your next flyover is. I love watching it until it passes the suns reflection of the earth, then it just flicks off like it disappeared!

I know it may be hard to believe, but one night I actually saw the ISS go passing by. I wish I remembered who pointed it out to me, but it was incredible.

Because of the Earth revolves around the Sun in an elliptical orbit and is not a perfectly circular, and because the earth is tilted on its axis (this creates seasons) a person taking this of kind of picture sees whats called an analemma pattern which takes one whole year to create.

Hi, thanks for asking. Here's how I did it:

About 38.96° N, 35.24° E

We can figure out the camera's latitude from this, right?

The Milky Way from a plane window

How the fuck did you do this? Do you have some kind of NASA-camera? Or are you just pressing your iPhone to the plastic window, using the obscure "Milky Way From Aircraft Time Lapse" setting?

It was explained in the original thread, he used an a7sii (fantastic low light camera) he did like 4 second exposures at 20,000 iso.

The full length video is available here

I captured this video on a flight from Phoenix to Baltimore a few weeks ago. I attached my camera to the window with a suction mount and I captured this timelapse over a period of around 2 hours. I covered the camera with a black t-shirt to block lights from reflecting on the window. For those asking about the light pollution, from what I understand, it isn't much of a problem with the thin atmosphere up at cruising altitude, and is only a problem at lower altitudes when the lights are reflected back by the atmosphere. I used the Sony A7s2 and the Samyang 24mm F/1.4 lens to capture this. all the images for the timelapse were shot at 3.2s, f/1.4, 24mm, 20000iso.

Most cameras don't even come close to having an ISO that high and if they do they are unusable due to noise, I have an sony a7sii and a Canon 60d and the Sony absolutely kills my canon at low light.

Edit: But you are correct that a good lens is a key factor, also a longer exposure obviously helps, but in this scenario he probably needed a short exposure time or it would look terrible because he was moving.

I photographed yesterday's Falcon 9 rocket launch from a helicopter over Cape Canaveral

I photographed yesterday's Falcon 9 rocket launch from a helicopter over Cape Canaveral

Your job does not suck...

More of a hobby that I'm lucky enough to occasionally make some side income from. I'm a high school student so I can't work full-time.

Either way, photographing rockets is pretty fun :D

Yeah. I started photography about 2.5 years ago, and after a year of shooting launches from public locations, I was credentialed under AmericaSpace to photograph launches as a media member, and setup cameras at the launchpads. Unfortunately due to this launch being at LC-39A, I wasn't able to be credentialed as I'm under 18 and Kennedy Space Center has some different rules than Cape Canaveral Air Force Station.

Nice! I saw the helicopter you were flying in, I was at jetty park!

NASA just debunked Gwyneth Paltrow’s latest snake oil

NASA just debunked Gwyneth Paltrow’s latest snake oil

If you are dumb enough to buy "healing stickers" from Gwyneth Paltrow, you probably aren't reading anything released by NASA.

“We regret not doing our due diligence before including the distributor’s information in the story of our product,” they said. “However, the origins of the material do not anyway impact the efficacy of our product.”

Very true. The origins of the materials used in this complete bullshit don't effect the fact that it does nothing at all.

Holy shit, $60 for a pack of 10 fucking stickers.

"Boosting cell turnover" ... So it's cancerous?

Edit: guys it was a joke, I understand that isn't literally cancer, but I would be willing to bet if it were true it could increase risk, however slightly.

James Webb Telescope is now inside Vacuum Test Chamber A at Johnson Space Center, Houston

James Webb Telescope is now inside Vacuum Test Chamber A at Johnson Space Center, Houston

What a gift to humanity this will be if they can pull this mission off flawlessly.

It's so scary that every rocket launch still has a decent chance of going up in flames. I know it's only like 5%, but that's still far from insignificant.

At my college in FIU, there was this speaker who would come to talk about astronomy and his name is James Webb. No joke. He then proceeded to convince us at the beginning of the presentation that the telescope was named after him.

I was stunned. This man was legendary and he was standing right in front of me. Needless to say, my attention was captivated for the next two hours.

At the end of the presentation, before we all leave, he suddenly says, "Oh and that thing about the telescope being named after me? Not true. It's just an incredible coincidence and I wanted to capture your attention for the presentation."

I've been bamboozled.

Do we know what rocket will be used for this mission? Does Ariane 5 have the load capacity for this?

EDIT: We are using Ariane 5, launch is scheduled for October 2018. Also its price tag is currently at $8.8billion.

Weird orbits hint 'Planet Ten' might lurk at solar system edge

Weird orbits hint 'Planet Ten' might lurk at solar system edge

Right, right. Of course that's only because Pluto is no longer considered a planet. If Pluto were a planet, then Planet X, which is Planet 9, would be Planet 10, while Planet 10, which orbits closer than Planet 9, would be Planet 11, which is to say the 10th planet in our Solar System, because it's between Planet 9, which is Pluto, and Planet 10 (which would be Planet 9 if Pluto weren't Planet 9), which is actually the 11th planet in our system, counting outwards from the Sun. But only if Pluto's a planet -- Planet 9 -- which it used to be, but isn't.

Really glad we got that cleared up.

For people wondering why this is news, this is NOT the Planet Nine that we've heard about for the past year. This is a theorized tenth planet which is supposedly Mars-sized and orbits closer in than the EarthX10-sized Planet Nine.

So, let me get this straight. Planet x, is planet 9, which is not to be confused with planet 10, which is in closer orbit than planet 9, which is the 9th planet in our solar system.

This has Monty Python written all over it...
