basically telescopes all over the world are acting as one to face the center of our milky way galaxy to try to take a picture of our supermassive black hole. now, if all goes according to plan, we should get data by the end of this year. the telescope will run for several days observing at different frequencies. i hope this works out, itll be YUGE like the gravity waves phenomena from a while back

So this will be the first actual picture of a blackhole maybe?

if all goes well, yes

Wow really? But I mean... how do you take a picture of something that has no light to it?

Different things like radio waves or something?

Pardon the ignorance.

its pretty complex stuff, im not a pro astronomer, but a cool thing about radio telescopes is that they can be very huge in regards to aperture. im sure youre familiar with the VLA. a bunch of telescopes in the desert that expand and contract when moving on railways. anyways, with radio telescopes, their apertures can increase without anything being in between them, like a mirror in most traditional telescopes. so we're essentially using an earth sized radio telescope to view into the milky way.

its super complex, but the radiowaves can help a lot since theyre the easiest to work with than things like hubble or stuff.

Pardon the ignorance.

A lot of telescopes also look out for different frequencies of light - gamma, xray,infrared etc.

Plus, in terms of visuals, you'd be able to see a black hole due to gravitational lensing - the pull of gravity around one is so strong it physically affects and warps space. As such, if you were to fly past one you'd see the light behind it (so, dust clouds, stars, etc in the distance) warping and changing as it bends to go around the event horizon.

Also, Black Holes that are actively "feeding" will have rings around them (like Gargantua in Interstellar). These rings are dust, particles, matter, gas and so forth that fornerly made up all kinds of objects being ripped apart and accelerated to relavtavistic velocities. As the dust hits other bits of dust, a lot of friction is generated and thus a fuck ton of heat and light.

Good gravitational lensing video below.


However, from the distance we are to Sag A*, there's simply too much dust, light and distance to really get a good picture of the gravitational lensing. The best we get is looking at radiation emitted and the orbits of stars around the galactic core.

black holes scary though ma no thanks

How can you put something all around a flat surface though?

You still haven't shown me why the earth is round as you keep claiming naru, i'm waiting.

people aren't dirt

also, they predict we'll see the ring around it, so it'll be a blob in the center while the surrounding area is dust and such

unrelated, space related w/e its space bump

Seen these Naru? Jupiters poles are beautiful

im more of a fan of saturns poles. the gas giants are really spectacular in the sense of how mysterious they are.

I love the hexagons on saturn's poles.

In general that planetary system has a lot of mysterious shit going on.
