Astronomers have detected a neutron star collision in an unexpected place, deep within a tiny, faint galaxy. Located about ...

Humanity has always been fascinated by space. We are able to see the universe with breathtaking clarity because of NASA's powerful telescopes. Astronomers have been able to take pictures of galaxies ...

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

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

Astronomers have spotted what may be one of the universe’s earliest barred spiral galaxies — a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, ...

Astronomers working with NASA’s James Webb Space Telescope have produced the sharpest wide-area map of dark matter ever ...

In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

A NASA team using the Hubble Space Telescope found an object in space never recorded before, nicknamed “Cloud-9.” Cloud-9 is a starless, gas-rich, dark-matter cloud considered a “relic” or remnant of ...
