What Are Black Holes? Check 7 Mesmerizing Pictures By NASA
The universe is filled with mysteries, and black holes are among the most captivating. These dense regions of space have such strong gravitational forces that nothing, not even light, can escape them. Check out mesmerizing images of Black Holes by NASA.
1. What Are Black Holes?
)
Black holes are incredibly dense objects formed when massive amounts of matter are compressed into tiny spaces. They have gravitational forces so strong at their event horizons (boundaries) that even light cannot escape.
2. Closest and Farthest Known Black Holes
The nearest known black hole, Gaia BH1, is about 1,500 light-years from Earth. The most distant one, located at the center of a galaxy called QSO J0313-1806, is around 13 billion light-years away.
3. Smallest and Largest Black Holes
Black holes vary widely in size. The smallest-known black hole has about 3.8 times the Sun’s mass, while the most massive, TON 618, weighs in at 66 billion solar masses.
4. Spaghettification
Objects venturing too close to a black hole are stretched vertically and compressed horizontally, a process known as "spaghettification," resulting in a noodle-like form.
5. Spinning Black Holes
Black holes spin, some extremely fast. GRS 1915+105 is the fastest-known, rotating over 1,000 times per second.
6. Galactic Particle Accelerators
Massive black holes at galaxy centers can accelerate particles to nearly the speed of light, creating high-energy jets that stretch vast distances into space.
7. Black Holes in Our Galaxy
Many galaxies the size of the Milky Way harbor supermassive black holes at their centers. Our galaxy’s central black hole, Sagittarius A*, has a mass of 4 million Suns.
