First evidence of gigantic remains from star explosions
Jan 10, 2019 (SPX)
A white dwarf is the dead core of a star. When it is paired with a companion star in a binary system, it can potentially produce a nova explosion. If the condit...
Scientists orchestrate a symphony of the stars
Jan 09, 2019 (SPX)
Astronomers from the Sloan Digital Sky Survey (SDSS) has announced the opening of a new "stellar library" containing spectra of thousands of stars in the Milky ...
SDSS: Science in the Library
Jan 09, 2019 (SPX)
This week, astronomers from the Sloan Digital Sky Survey (SDSS) announced the opening of a new "stellar library" containing spectra of thousands of stars in our...
Dark Energy Survey Completes Six-Year Mission
Jan 09, 2019 (SPX)
After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey (DE...
Programming light on a chip
Jan 09, 2019 (SPX)
The platform draws inspiration from atomic systems and could have a wide range of applications including photonic quantum information processing, optical signal...
Shutdown could delay fix for camera on Hubble telescope
Jan 09, 2019 (UPI)
"Hubble is still conducting science observations with its other instruments (one camera and two spectrographs) -- more than enough to keep the observatory activ...
'Missing' galactic mergers come to light
Jan 09, 2019 (SPX)
In new research, a team led by Rebecca Nevin designed a computer program that scans through surveys of galaxies to look for a wide range of signs that a merger ...
Citizen scientists find new world with NASA telescope
Jan 08, 2019 (SPX)
"It's a very exciting discovery due to how it was found, its temperate orbit and because planets of this size seem to be relatively uncommon," said Adina Feinst...
TESS rounds up its first planets, snares far-flung supernovae
Jan 08, 2019 (SPX)
The mission's sensitive cameras also captured 100 short-lived changes - most of them likely stellar outbursts - in the same region of the sky. They include six ...
Nearly a third of all galaxy clusters may have been previously unnoticed
Jan 08, 2019 (SPX)
Fritz Zwicky, famous American astronomer of Swiss origin, arrived in 1933 at the astonishing conclusion that even though galaxies are the signposts of galaxy cl...
Lifting the veil on star formation in the Orion Nebula
Jan 08, 2019 (SPX)
This is surprising because until now, scientists thought that other processes, such as exploding stars called supernovae, were largely responsible for regulatin...
Hubble takes gigantic image of the Triangulum Galaxy
Jan 08, 2019 (SPX)
This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising view of the 40 billion stars that make up one of the mos...
Tiny satellites could be 'guide stars' for huge next-generation telescopes
Jan 07, 2019 (SPX)
But knowing more about the planet, including whether it harbors oxygen, water, and other signs of life, requires far more powerful tools. Ideally, these would b...
Dark matter on the move
Jan 04, 2019 (SPX)
In the new work, scientists from the University of Surrey, Carnegie Mellon University and ETH Zurich set out to hunt for evidence for dark matter at the centres...
Next up: Ultracold simulators of super-dense stars
Jan 04, 2019 (SPX)
The findings are detailed this week in the journal Science and involve new techniques for laser cooling clouds of rapidly expanding plasma to temperatures about...
Color-changing brittle stars see without eyes
Jan 02, 2019 (UPI)
Previously, scientists discovered that the red brittle star is covered in light-sensitive cells, but researchers weren't sure how the species utilized them. The...
Webb Telescope wrapped in a mobile clean room
Jan 02, 2019 (SPX)
All satellites and observatories are created in clean rooms. Clean rooms filter out harmful contaminants, as even a speck of dust or a fingerprint could severel...
Massive new dark matter detector gets its 'eyes'
Jan 02, 2019 (SPX)
The first of two large arrays of photomultiplier tubes (PMTs) - powerful light sensors that can detect the faintest of flashes - arrived last Thursday at the Sa...
New insights into pion condensation and the formation of neutron stars
Jan 01, 2019 (SPX)
These city-size heavy stellar objects are so dense that on Earth, one teaspoonful would weigh a billion tons. Recently, researchers from the RIKEN Nishina Cente...
Strong interactions produce a dance between light and sound
Dec 27, 2018 (SPX)
A team of researchers from Imperial College London, the University of Oxford, and the National Physical Laboratory have experimentally achieved a long-standing ...
