Do stars fall quietly into black holes, or crash into something utterly unknown?

Tue, 05/30/2017 - 11:51am
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.

Camera on NASA's Lunar Orbiter survived 2014 meteoroid hit

Mon, 05/29/2017 - 2:21pm
Images from LRO show a brief violent movement of one of the Narrow Angle Cameras on NASA's Lunar Orbiter in October of 2014.

Extreme Jupiter weather and magnetic fields

Thu, 05/25/2017 - 2:58pm
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.

Juno mission to Jupiter delivers first science results

Thu, 05/25/2017 - 2:15pm
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.

The big star that couldn't become a supernova

Thu, 05/25/2017 - 2:15pm
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.

Just after the Big Bang: Galaxies created stars a hundred times faster now

Wed, 05/24/2017 - 1:11pm
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.

How most antimatter in the Milky Way forms: Mystery solved

Wed, 05/24/2017 - 10:45am
Astrophysicists have now shown how most of the antimatter in the Milky Way forms.

Volunteers help find star that exploded 970 million years ago, predating the dinosaurs

Wed, 05/24/2017 - 10:15am
Online volunteers have helped astronomers find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.

Biggest ever simulations help uncover the history of the galaxy

Wed, 05/24/2017 - 8:46am
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.

New object near supermassive black hole in famous galaxy

Tue, 05/23/2017 - 2:41pm
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.

CAST project places new limitations on dark matter

Tue, 05/23/2017 - 10:43am
CERN research results deliver no evidence for the existence of solar axions.

ASKAP telescope to rule radio-burst hunt

Tue, 05/23/2017 - 8:33am
A CSIRO telescope in Western Australia has found its first 'fast radio burst' from space after less than four days of searching.

How radioactive decay could support extraterrestrial life

Tue, 05/23/2017 - 8:19am
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.

Kepler telescope spies details of TRAPPIST-1 system's outermost planet

Tue, 05/23/2017 - 8:18am
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.

A new approach to forecasting solar flares?

Mon, 05/22/2017 - 8:10am
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.

Mapping super massive black holes in the distant universe

Fri, 05/19/2017 - 1:18pm
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.

History of Titan's landscape resembles that of Mars, not Earth

Thu, 05/18/2017 - 2:38pm
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 mission uncovers a dance of electrons in space

Thu, 05/18/2017 - 2:02pm
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.

Moon orbits third largest dwarf planet in our solar system

Thu, 05/18/2017 - 2:02pm
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.

Icy ring surrounds young planetary system

Thu, 05/18/2017 - 2:02pm
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.
