Astronomers focused the Hubble Space Telescope on an exoplanet that had already been seen losing its atmosphere, which forms an enormous cloud of hydrogen, giving the planet the appearance of a giant comet.
In research that may prove useful to future lunar explorers, scientists have created the first quantitative map of water and its chemical building blocks trapped in the uppermost portion of the Moon's soil.
An international team of researchers has discovered a way to use observations at ultraviolet (UV) wavelengths to uncover characteristics about superluminous supernovae previously impossible to determine.
The Rosetta space probe discovered a large amount of organic material in the nucleus of comet 'Chury'. Two researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the Solar System.
Astronomers have discovered two rapidly rotating radio pulsars with the Low-Frequency Array (LOFAR) radio telescope by investigating unknown gamma-ray sources uncovered by NASA's Fermi Gamma-ray Space Telescope.
New research revealed that the entire zoo of electromagnetic radiation streaming from the Crab Nebula has its origin in one population of electrons and must be produced in a different way than scientists have.
There could be water on multiple Earth-sized planets orbiting the recently discovered TRAPPIST-1 dwarf star - making them potentially habitable - according to an international collaboration of researchers.
Magnetic fields play an important role in the physics of the interstellar medium, but they are very difficult to observe at vast distances corresponding to large look-back times in the cosmic history. An international team of astronomers was able to measure the magnetic field in a galaxy beyond the local volume, as seen 4.6 billion light years away at a redshift of 0.439.
