Astronomers have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein's General Theory of Relativity.
Images from LRO show a brief violent movement of one of the Narrow Angle Cameras on NASA's Lunar Orbiter in October of 2014.
New observations about the extreme conditions of Jupiter's weather and magnetic fields by astronomers have contributed to the revelations and insights coming from the first close passes of Jupiter by NASA's Juno mission.
NASA's Juno mission is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released today. The Juno spacecraft has been in orbit around Jupiter since July 2016, passing within 3,000 miles of the equatorial cloudtops.
For the first time in history, astronomers have been able to watch as a dying star was reborn as a black hole. It went out with a whimper instead of a bang.
A team of astronomers has discovered a new kind of galaxy which, although extremely old -- formed less than a billion years after the Big Bang -- creates stars more than a hundred times faster than our own Milky Way.
Astrophysicists have now shown how most of the antimatter in the Milky Way forms.
Online volunteers have helped astronomers find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.
Thousands of processors, terabytes of data, and months of computing time have helped a group of researchers in Germany create some of the largest and highest resolution simulations ever made of galaxies like our Milky Way.
When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.
CERN research results deliver no evidence for the existence of solar axions.
A CSIRO telescope in Western Australia has found its first 'fast radio burst' from space after less than four days of searching.
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn's moon Enceladus, Jupiter's moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.
A team of astronomers has used data gathered by the Kepler Space Telescope to observe and confirm details of the outermost of seven exoplanets or-biting the star TRAPPIST-1.
The emerging discipline of space meteorology aims to reliably predict solar flares so that we may better guard against their effects. Using 3D numerical models, an international team has discovered a proxy that could be used to forecast an eruptive event. The proxy is associated with magnetic helicity, which reflects the extent of twist and entanglement of the magnetic field.
Astronomers have constructed the first map of the Universe based on the positions of supermassive black holes, which reveals the large-scale structure of the Universe.
In a paper published in Science, researchers report that Titan, like Mars but unlike Earth, has not undergone any active plate tectonics in its recent past. The upheaval of mountains by plate tectonics deflects the paths that rivers take. The team found that this telltale signature was missing from river networks on Mars and Titan.
NASA's MMS mission studies how electrons spiral and dive around the planet in a complex dance dictated by the magnetic and electric fields, and a new study revealed a bizarre new type of motion exhibited by these electrons.
Astronomers have uncovered a moon orbiting the third largest dwarf planet, 2007 OR10, in the frigid outskirts of our solar system called the Kuiper Belt.
ALMA has made the first complete millimeter-wavelength image of the ring of dusty debris surrounding the young star Fomalhaut. This remarkably well-defined band of rubble and gas is likely the result of exocomets smashing together near the outer edges of a planetary system 25 light-years from Earth.
