In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

A fresh analysis of gravitational wave data from a 2020 collision between a black hole and a neutron star has produced the first measured evidence of an eccentric, oval-shaped orbit in this type of ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from Earth.

CC0 Usage Conditions ApplyClick for more information. A bright burst of X-rays has been discovered by NASA's Chandra X-ray Observatory in a galaxy 6.6 billion light years from Earth. This event likely ...

We all know how weird black holes are, but did you know there is another type of star that is just as strange? Welcome to the universe of neutron stars.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...
