The low carbon levels are particularly interesting, as previously discovered “pristine” or metal-poor stars generally displayed high carbon levels. Astronomers believed that relatively heavier ...

The newly found object has an estimated mass about one million times that of the Sun. Its true identity remains uncertain: it could be a dense clump of dark matter roughly 100 times smaller than any ...

In a groundbreaking study published inNature Astronomy, astronomers have identified the lowest-mass dark object ever discovered through gravitational lensing. This breakthrough provides significant ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density – given that the universe contains a lot of relatively empty space, could ...

Astronomers have detected two extraordinary gravitational wave events that may have come from black holes formed in earlier ...

In a distant stretch of the universe, more than 10 billion light-years from Earth, astronomers have discovered something ...

In 1867, Lord Kelvin imagined atoms as knots in the aether. The idea was soon disproven. Atoms turned out to be something ...

Renowned astrophysicist Neil deGrasse Tyson continues to dismiss the hypothesis of a Harvard University professor that a ...

His answer? Dark matter, the hidden mass that scientists cannot see but know is present because of how surrounding objects ...

Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.
