NICER delivers best-ever pulsar measurements and first surface map
Dec 13, 2019 (SPX)
The pulsar in question, J0030+0451 (J0030 for short), lies in an isolated region of space 1,100 light-years away in the constellation Pisces. While measuring th...
New NASA image provides more details about first observed interstellar comet
Dec 13, 2019 (SPX)
The comet, called Comet 2I/Borisov (the "I" stands for interstellar), was spotted near a spiral galaxy known as 2MASX J10500165-0152029. It was approximately 20...
A galactic dance
Dec 13, 2019 (SPX)
The existence of our Universe is dependent upon interactions - from the tiniest subatomic particles to the largest clusters of galaxies. At galactic scales, int...
Dark matter may explain mysterious gamma ray source at center of Milky Way
Dec 12, 2019 (UPI)
Gamma rays are the the most energetic electromagnetic waves. Throughout the Milky Way, astronomers have traced gamma rays to two sources: supernovae and pulsars...
ALMA spots most distant dusty galaxy hidden in plain sight
Dec 12, 2019 (SPX)
Dusty star-forming galaxies are the most intense stellar nurseries in the universe. They form stars at a rate up to a few thousand times the mass of the Sun per...
How to shape a spiral galaxy
Dec 11, 2019 (SPX)
Magnetic fields play a strong role in shaping these galaxies, according to research from the Stratospheric Observatory for Infrared Astronomy, or SOFIA. Scienti...
Second stellar population found in Milky Way's thick disk
Dec 11, 2019 (SPX)
The new thick disk component, called metal weak thick disk (MWTD) or metal poor thick disk, differs from the canonical one, the thick disk (TD), in particular f...
Scientists find further evidence for a population of dark matter deficient dwarf galaxies
Dec 10, 2019 (SPX)
This study may challenge the formation theory of dwarf galaxies in the framework of standard cosmology and may provide new clues to the nature of dark matter. T...
Stardust from Red Giants
Dec 10, 2019 (SPX)
Around 4.5 billion years ago, an interstellar molecular cloud collapsed. At its centre, the Sun was formed; around that, a disc of gas and dust appeared, out of...
Russian astrophysicists discovered a neutron star with an unusual magnetic field structure
Dec 10, 2019 (SPX)
The neutron star GRO J2058+42 studied by the researchers offers an insight into the internal structure of neutron star's magnetic field only at a certain phase ...
Twenty years of X-ray astronomy with XMM-Newton
Dec 10, 2019 (SPX)
Since its launch, XMM-Newton has simultaneously collected X-rays, visible and ultraviolet light and demonstrated its role as one of the most important astronomi...
Swiss space telescope CHEOPS launch set for 17 December
Dec 06, 2019 (SPX)
CHEOPS (short for CHaracterising ExOPlanet Satellite) consists of a space telescope developed and assembled by the University of Bern, in collaboration with the...
Scientists have found out why photons flying from other galaxies do not reach the Earth
Dec 05, 2019 (SPX)
Andrey Saveliev said: "In the Universe there are extragalactic objects such as blazars, which very intensively generate a powerful gamma-ray flux, part of photo...
Scientists reveal potential new class of x-ray star system
Dec 05, 2019 (SPX)
"Scientists already knew that the transfer of mass from one star to another is one of the most important processes in astronomy, because it produces events that...

Dec 05, 2019 (SPX)
In a paper published in the journal Monthly Notices of the Royal Astronomical Society, a team of 38 scientists led by researchers from Australia's ARC Centre of...
Gas giant composition not determined by host star
Dec 04, 2019 (SPX)
In their youths, stars are surrounded by a rotating disk of gas and dust from which planets are born. Astronomers have long wondered how much a star's makeup de...
