Astrophysicists measure precise rotation pattern of sun-like stars for the first time

Thu, 2018-09-20 16:09
Scientists have measured the differential rotation on Sun-like stars for the first time, and their findings challenge current science on how stars rotate.

Matter falling into a black hole at 30 percent of the speed of light

Thu, 2018-09-20 11:55
Astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in the center of the billion-light year distant galaxy PG211+143. The team used data from the European Space Agency's X-ray observatory XMM-Newton to observe the black hole.

Gaia hints at our Galaxy’s turbulent life

Wed, 2018-09-19 13:30
Our Milky Way galaxy is still enduring the effects of a near collision that set millions of stars moving like ripples on a pond, the Gaia star mapping mission has shown.

Looking back in time to watch for a different kind of black hole

Wed, 2018-09-19 10:10
A simulation has suggested what astronomers should look for if they search the skies for a direct collapse black hole in its early stages.

Magellanic Clouds duo may have been a trio

Tue, 2018-09-18 09:08
Two of the closest galaxies to the Milky Way -- the Large and Small Magellanic Clouds -- may have had a third companion, astronomers believe. New research describes how another 'luminous' galaxy was likely engulfed by the Large Magellanic Cloud some three to five billion years ago.

NASA's TESS shares first science image in hunt to find new worlds

Mon, 2018-09-17 15:36
NASA's Transiting Exoplanet Survey Satellite, which began science operations in July, has released its first full frame image using all four of its cameras.

Never-before-seen features found around a neutron star

Mon, 2018-09-17 11:43
An unusual infrared light emission from a nearby neutron star detected by NASA's Hubble Space Telescope could indicate new features never before seen.

Ice volcano activity on dwarf planet Ceres

Mon, 2018-09-17 11:15
Ice volcanoes on the dwarf planet Ceres generate enough material to fill one movie theater each year, new calculations show.

When is a star not a star?

Mon, 2018-09-17 10:13
The line that separates stars from brown dwarfs may soon be clearer. Astronomers demonstrate that brown dwarfs can be more massive than astronomers previously thought.

BUFFALO charges towards the earliest galaxies

Thu, 2018-09-13 11:39
The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.

VLBA measures asteroid's characteristics

Thu, 2018-09-13 11:38
Astronomers took advantage of a celestial alignment to make a novel and creative radio observation yielding information about the size, shape, and orbit of an asteroid.

Stunning details of spiral galaxy NGC 3981

Wed, 2018-09-12 08:13
FORS2, an instrument mounted on ESO's Very Large Telescope, has observed the spiral galaxy NGC 3981 in all its glory. The image was captured as part of the ESO Cosmic Gems Programme, which makes use of the rare occasions when observing conditions are not suitable for gathering scientific data.

Astronomers witness birth of new star from stellar explosion

Wed, 2018-09-12 08:12
Astronomers have observed a new phenomena in the aftermath of a stellar explosion.

Evidence of early planetary shake-up

Mon, 2018-09-10 11:12
Scientists have studied an unusual pair of asteroids and discovered that their existence points to an early planetary rearrangement in our solar system.

Legacy of NASA's Dawn, near the end of its mission

Fri, 2018-09-07 17:59
NASA's Dawn mission is drawing to a close after 11 years of breaking new ground in planetary science, gathering breathtaking imagery, and performing unprecedented feats of spacecraft engineering.

Pluto should be reclassified as a planet, experts say

Fri, 2018-09-07 11:04
The reason Pluto lost its planet status is not valid, according to new research.

Galactic 'wind' stifling star formation is most distant yet seen

Thu, 2018-09-06 14:15
For the first time, a powerful 'wind' of molecules has been detected in a galaxy located 12 billion light-years away. Probing a time when the universe was less than 10 percent of its current age, astronomers sheds light on how the earliest galaxies regulated the birth of stars to keep from blowing themselves apart.

New exoplanet found very close to its star

Wed, 2018-09-05 16:19
Using data from NASA's Kepler Space Telescope, an international team has discovered a new exoplanet twice the size of Earth. It orbits its star every six days and is thus very close to it, about 10 times closer than Mercury is to the Sun.

Saturn's famous hexagon may tower above the clouds

Wed, 2018-09-05 15:54
The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds.

Radio observations confirm superfast jet of material from neutron star merger

Wed, 2018-09-05 13:18
The supersharp radio 'vision' of a continent-wide collection of radio telescopes has answered an outstanding question about the aftermath of a merger of two neutron stars.
