Star Turns into a Black Hole Before Hubble’s Eyes

Hubble just witnessed the birth of a black hole for the first time. But astronomers didn’t expect this kind of unusual birth. Usually, when a massive star expands its fuel, its core collapses into a dense object. Thus, sending the rest of its gas outward in an event is called a supernova. However, this was not the case...

Ten Thousand Black Holes Hiding in the Center of the Milky Way

A recent study suggests that the center of the Milky Way is hiding about ten thousand black holes. But we have never previously been able to see them. For decades astronomers have suspected there might be a host of smaller black holes. All of them surrounding the supermassive one, Sagittarius A*, that sits at the center of...

Certain Black Holes Might Erase your Past

Entering a black hole would be impossible to survive… or would it? A mathematician suggests that certain black holes might obliterate your past. Equations of the theory of relativity suggest that certain black holes can erase the past conditional of the observer. Also they could have an infinite number of possible...

This is what Happens when Black Holes Collide

So, a black hole is a collapsed core of a very big star. Their gravity is so strong, as we know, even light can’t escape. However, black holes can collide. In the early 20th century, Einstein predicted that gravity is a distortion of spacetime. He also predicted that massive objects moving through spacetime should...

Neutron Star Collision Led to a Rumble of Gravitational Waves

Scientists have detected ripples in the fabric of space and time from a neutron star collision. They call those ripples gravitational waves. Two neutron stars, each small as a city but heavier than the sun, collided, thus forming a black hole. This powerful event in space threw gravitational waves and light toward our planet....

LIGO Detects A Third Black Hole Collision

Scientists have detected a black hole collision. It lies some 3 billion light-years away, much farther than the previous two discoveries. This is the third time since 2015 that these space-time vibrations known as gravitational waves from the merger of a pair of giant black holes has been observed via an instrument called...

What Exactly Are Black Holes And How Strong Are They

A black hole is a place in space where gravity pulls so much that even light can’t get out. That’s because the matter has been squeezed into a tiny space. Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special...

Merging Galaxies Have Enshrouded Black Holes

Stars, gas, and dust can orbit black holes for long periods of time until a major disruption pushes the material in.  Only high-energy X-rays escape telling astronomers about the accreting black holes within. Galaxies combine and their central black holes approach each other. Thus, they push the gas and dust, surrounding it,...
