A newly published study shows that nearby disk galaxies unexpectedly reached their current state long after much of the universe’s star formation had ceased. A…
Scientists using the XMM-Newton X-ray astronomy satellite discovered a new signature of a source of low-energy hadronic cosmic rays in the vicinity of the Arches…
The combined effort of NASA’s Swift satellite, the European Space Agency’s XMM-Newton observatory, and several ground-based facilities has allowed scientists to X-ray the colliding stellar…
Quantum chromodynamics is the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, and how these form…
R Sculptoris, an elderly star, located 1,500 light-years from Earth, has been observed in the final stages of stellar life, slowly shedding the outer layers…
A team of scientists discovered a star called S0-102 that orbits the black hole at the center of our Milky Way galaxy in 11.5 years….
The Herschel space observatory has discovered water vapor in a pre-stellar core in the constellation of Taurus known as Lynds 1544. This is the first…
NASA’s Swift satellite detected high-energy X-rays a few degrees from the center of our galaxy, toward the constellation Sagittarius. Produced by a rare X-ray nova,…
