Scientists "see" things through specialized equipment that identify waves that are invisible to a human eye i.e. microwaves, gamma waves, etc.
Also because we are in the Milky Way, right? SO There are many stars in our galaxy. So, they can see it because it was a big black gap right in our galaxy and they could see stars flowing in it being sucked into it. Like when you drain the bathetub after a bubble bath. You can see the little torpido of water in it. Even when it's the same color. You get it?Black holes don't give off gamma rays or microwaves. That's the whole point. (Except hawking radiation, of course, but that is hard to detect as the effect is so small in large objects.)Seeing objects that don't reflect light is tricky business. And black holes are as mysterious as a target can be. Not even light can escape them. This is a pretty tricky problem for scientists, whose instruments usually rely on light-- whether it's visible light, radio waves, X-rays or infrared-- to observe objects in space.
One method to see black holes has been to watch the fate of an object falling into one of these cosmic graves. If material actually falls into a black hole, it gets shredded apart and it heats up. As it heats up, it starts emitting light and this radiation we can observe. In particular, we can often see X-rays coming from black holes. When gas orbits around a black hole it tends to get very hot because of friction. It starts emitting X-rays and radio waves. So a lot of times black holes can be found and studied by looking for bright sources of X-rays and radio waves in the sky.
These X-rays do not get through the Earth's atmosphere and can only be seen with telescopes positioned in space, such as the Hubble telescope.
The strong gravitational attraction of a black hole affects the motion of nearby objects. When astronomers see a star circling around something, but they cannot see what that something is, they may suspect it is a black hole. Astronomers can even figure the mass of a black hole by measuring the mass of the star and its speed. The same kind of calculation can be done with black holes at the center of many galaxies, including our own galaxy, the Milky Way. In fact, at the very center of our galaxy, radio and X-ray telescopes have detected a powerful source called 'Sagittarius A', identified as this massive black hole.

Why do astronomers hypothesize that there is a supermassive black hole at the center of the milky way?
That's because they actually observed it.
Can you see a video of the black hole in space?
Dude it is black for a reason. You can not see the black hole itself, but you can see the black hole distorting light, eating stars, or it's gravitational pull.
How do astronomers measure the mass of a supermassive black hole?
By observing the movement of nearby objects. The gravity of the black hole will accelerate such an object according to Newton's Second Law (F=ma). More specifically, the details of the orbit of a star that moves around the black hole will vary, depending on the black hole's mass.
Can you see a black hole when you are on eath?
You cannot see a black hole when you are on Earth, unless a black hole were to absorb Earth, which even then, you would see it in a split-second before it would engulf you
What led astronomers to believe that this galaxy contained a black hole?
Our galaxy does not contain "a" black hole, it contains thousands, perhaps millions, of them.Astronomers believe there is a supermassive black hole near the center of the galaxy, with a mass of about 4 million solar masses. They reached this conclusion, among other things, by observing objects moving around it. This makes it possible to make an estimate of the mass. Some of the objects are quite near the ... object, whatever it is, and astronomers know of nothing except a black hole that can have such a large mass in such a small space.
Why do astronomers have a difficult time viewing black holes?
You cant see a black hole because the gravitational pull of it is so strong that not even light can escape from it. Astronomers find them through observing the space matter that they pull into them, not the hole itself.
How do astronomers know the black hole exist?
Astronomers know because they have studied star patterns and placements and know when there has been a change between where there is a black hole and where there isn't one.
How do astronomers find the mass of a black hole?
By observing the movement of nearby objects.
Are you reley gowine to be suckt in to a black hole?
Astronomers indicate the probability of us all really going to be sucked into a black hole to be quite low.
How can you say there is a black hole?
You can't see the black hole but you can see its inflence on its environment. (You can see matter that is sucked into the black hole)
What has actually been seen by Astronomers?
A black hole, exoplanets. It has always been inferred.
What do astronomers think is hiding in the middle of the core galaxy?
A black hole or a worm hole :) good luck
Why do astronomers have difficulty studying the black hole?
Black holes do not emit light, so we cannot observe them directly
In what part is a black hole in the universe?
Astronomers believe that black holes exist in the center of every universe. They even think that there may be a black hole in the center of our galaxy, the Milky Way
Where is the black hole now?
Astronomers say that there are several, possibly many, black holes, all a long way from Earth.
Can you see a video of the black hole in space?
Dude it is black for a reason. You can not see the black hole itself, but you can see the black hole distorting light, eating stars, or it's gravitational pull.
How can you tell if there is a black hole?
Astronomers look for black holes by searching for their effects (the hole itself by definition can't be seen). Some of the possible effects are gravitational lensing and electromagnetic radiation from the hole's accretion disk.
