According to theoretical calculations, dark matter should weigh five times as much as the ordinary matter that makes up our bodies. Our sensors cannot see it, and the only way to see its effects is through gravity. A common method for measuring its…
Before the Hubble Space Telescope (HST), it was thought that the universe was slowing in its expansion and might someday fold back in on itself. In 1998, the HST revealed that rather than slowing, the rate of universal expansion is actually picking…
NASA released an intriguing photo showing the Earth spreading " filaments of dark matter " in yet another puzzling twist on the elusive subject. Although it is not known exactly what dark matter is, scientists know that it is essential …
Some unexplained results from the XENON1T dark-matter detector — a 1,300-kg vat of super-pure liquid xenon shielded from cosmic rays in a cryostat submerged in water deep 1.5 km beneath the Gran Sasso mountains of Italy — may have been caused by da…
Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy’s Apennine Mountains. A new study, led by researchers at the University of C…
A striking new picture of the Milky Way has been released by NASA. The picture is of the galaxy's violent, super-energized 'downtown' and is a composite of 370 observations from NASA's Chandra X-ray Observatory. The pictures…
