You can't really "observe" a black hole. About the best you can do is look for their effects on their immediate environment, and one of the best tools for that is an X-ray telescope... matter falling into the black hole releases a lot of energy, and some of that comes out as X-rays.

What kind of shoes did Stanley get hit by in Holes movie?
its qutiona
What kind of telescope uses a concave mirror?
Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.
What kind of truck does Mr sir have in holes?
I think it is an f-350
From the book holes how does Stanley yelnats acts?
He is helpful,kind, smart and relaxed
What kind of point of view is the story holes?
Third person point of view.
What kind of Astronomers study black holes?
specifically, "astronomers" that study black holes are called cosmologists.
What kind of scientist uses telescopes to study space?
An astronomer uses telescopes to study space. They observe celestial objects like stars, planets, galaxies, and other phenomena to understand the universe's properties and behavior.
What kind of radiation does a black hole emit?
Black holes are believed to emit something called Hawking radiation.
What do you call the kind of telescope that the scientist use?
Scientists typically use optical telescopes to observe and study celestial objects and phenomena in the universe. These telescopes gather and focus light to create detailed images of distant objects, helping scientists to learn more about the universe.
What is the first kind of telescopes?
hubble
What kind of energy waves do black holes emit?
Black holes emit a form of energy called Hawking radiation, which consists of particles being emitted from the black hole's event horizon. This radiation causes the black hole to slowly lose mass over time.
What kind of stars become black holes low mass or medium mass or high mass?
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
Do black holes have an atmosphere?
No. Their gravitational pull is simply too great to maintain any kind of atmosphere.
If a black hole is black how do astronomers see them?
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.
What kind of telescopes can only operate in space?
international
Do large black holes die?
Kind of. They go dormant if their is nothing in their surroundings to absorb. They have a constant swirling cloud of dust and gases if they are active, but they are simply a black orb if they are domant.
How do you know blackholes exist?
It is a tricky question because black holes are invisible, but scientists know that they are exist because black holes distort light, so it kind of change the light and also it sucks everything into it, so when scientists see stars starting to disappear, thats mean there is a black hole.
