Researchers may have witnessed the birth of a black hole

Researchers believe they might have an explanation for an incredibly bright event that took place in a distant dwarf galaxy. Scientists observed it last June when the object in question ...

Mysterious 'Cow' Blast in Space May Reveal Birth of a Black Hole

A weirdly bright and brief blast dubbed "The Cow," which researchers first spotted last June, was likely generated by a newborn black hole or superdense stellar corpse called a neutron star, ...

Mysterious space 'Cow' explosion could be birth of black hole - CNET

The unusual space "Cow" continues to baffle astronomers but two new theories suggest black holes are to blame for the strange explosion.

This Exploding 'Cow' May Be the First Black Hole Birth Ever Observed

Is this exploding "Cow" the first live birth of a black hole or neutron star ever seen from Earth?

For the first time, astronomers see the signatures of a newly birthed black hole or neutron star

For the first time ever, astronomers have directly witnessed the birth of a super dense object far outside of our galaxy — the rise of either a black hole or a collapsed star ...

Birth of a black hole or neutron star is captured for the first time

Experts from Northwestern University studying a celestial object called AT2018cow have concluded it may be the first time the formation of a new black hole or neutron star has been captured.
