Discovery of Many New Ultra-Diffuse Galaxies in Clusters
Mar 01, 2019 (SPX)
Galaxies, like our Milky Way, can live in large groups with many others, the so-called galaxy clusters. Such associations contain a potpourri of galaxies with m...
Dark matter may be hitting the right note in small galaxies
Feb 28, 2019 (SPX)
Dark matter is a mysterious and unknown form of matter that comprises more than 80 per cent of matter in the Universe today. Its nature is unknown, but it is be...
ALMA differentiates two birth cries from a single star
Feb 27, 2019 (SPX)
Stars in the Universe have a wide range of masses, ranging from hundreds of times the mass of the Sun to less than a tenth of that of the Sun. To understand the...
World-first technology to revolutionise space imaging
Feb 26, 2019 (SPX)

Australia Designs Local Infrastructure for World's Largest Telescope
Feb 26, 2019 (SPX)
The SKA will explore the universe in unprecedented detail, doing so hundreds of times faster than any current facility. Antennas will be located in both Austral...
Stellar wind of old stars reveals existence of a partner
Feb 26, 2019 (SPX)
The stellar wind is not more intense than normal, but is affected by a partner that was overlooked until now: a second star that circles the red giant. These ar...
Quantum dots can spit out clone-like photons
Feb 25, 2019 (SPX)
The study, which involves using a family of materials known as perovskites to make light-emitting particles called quantum dots, appears in the journal Science....
In Colliding Galaxies, a Pipsqueak Shines Bright
Feb 21, 2019 (JPL)
The most stunning features of the Whirlpool galaxy - officially known as M51a - are the two long, star-filled "arms" curling around the galactic center like rib...
Firefly-inspired surfaces improve efficiency of LED lightbulbs
Feb 20, 2019 (SPX)
"LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering. "Overall commercial LED efficiency is currentl...
ASU astronomer helps research team zero in on puzzling astrophysical object
Feb 20, 2019 (SPX)
The star, LSPM J0207+3331 or J0207 for short, is forcing researchers to reconsider models of planetary systems and could help us learn about the distant future ...
Confirming a source of the process behind auroras and the formation of stars
Feb 20, 2019 (SPX)
The phenomenon takes place in plasma, the state of matter composed of free electrons and atomic nuclei, or ions, that makes up 99 percent of the visible univers...
Team uses quantum of light to create new quantum simulator
Feb 20, 2019 (SPX)
Turns out we're not talking about magic - we're talking atomic and subatomic particles. An electron, for instance, can be in multiple places at once. This is a ...
