Last Answer : Using NASA's Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light
Description : Has the quantity of stellar mass of the Milky Way changed much since its formation? -Space
Last Answer : In March 2019, astronomers reported that the mass of the Milky Way galaxy is 1.5 trillion solar masses within a radius of about 129,000 light-years, over twice as much as was determined in earlier studies, and suggesting that about 90% of the mass of the galaxy is dark matter.
Description : How black hole has a vast attractive force? What is its density in comparison with Earth and Sun? -Space
Last Answer : There are two things that affect the escape velocity - the mass of object and the distance to the center of that object. For example, a rocket must accelerate to 11.2 km/s in order to escape Earth's gravity ... the mass of our sun would need to be squeezed into a volume with a radius of about 3 km.
Description : The black hole is approximately 55 million light years away, how was its existence known and how was it pictured with just telescopes? -Space

Because of this, black holes that do not gain mass through other ... and ultimately vanish. For all except the smallest black holes, this would happen extremely slowly.
Description : A black hole 'belches' light and radiation whenever something falls into its event horizon. What does that mean and why does that happen? -Space
Last Answer : A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos
Description : What do we call the boundary around a black hole where nothing can escape its gravity? -Space
Last Answer : The boundary of the region from which no escape is possible is called the event horizon.
Description : The M87 black hole is supermassive, but relatively compact for its mass. What size does it occupy? -Space
Last Answer : Such incredibly compact objects cause infinite curvature in the fabric of spacetime. Everything that falls into a black hole is sucked toward the singularity. At some distance away from the singularity ... star. Black holes grow by accreting surrounding matter and by merging with other black holes.

Description : Are survivalists like Doomsday Preppers building shelters in outer space yet?
Last Answer : If they’re smart enough to build a vast financial empire, they’re probably smart enough to realize that there’s not much that can be done to fight the end of the world. A bunker is probably a lot safer and more practical, perhaps a lair in a volcano would be even safer than that.
Description : Can space junk be mined for metals and minerals?
Last Answer : Right now the cost to do it would outweigh what they could get for it. And it can also be pretty dangerous I would guess, too. It would be a good idea to get it down.

Last Answer : No, not that useful. I mean, I suppose in the long-long run, it’ll add up, but I don’t think the effect would be that great or useful to you. I would say you are better off just getting more storage.
Description : Is there really an up/down, left/right, north/south in space?
Last Answer : directions are three dimensional in space, (perhaps more) and the up/down, left/right, north/south directions refer more to two dimensional maps. Pluto misses you as well, and sends its’ love.
Description : Do you think that with all the space crafts going up into space is damaging the ozone?
Last Answer : I don’t think it works like that. The ozone layer is gas. It’s not like a balloon where the rockets are punching wholes in it. It’s more like a submarine in the ocean. As it goes down, the water just takes it’s place. Same concept applies here. The gasses don’t stay torn apart.
Description : On the space shuttle I have seen pictures with a covering over the tail end. What is this for?
Last Answer : Aerodynamics when it’s being shipped back to Cape Canaveral. It reduces drag so that when piggy-backed on the 747, it doesn’t cause undo dragand air resistance.
