First Light for SPECULOOS Telescopes at Paranal Observatory
Dec 07, 2018 (SPX)
The SPECULOOS Southern Observatory (SSO) has been successfully installed at the Paranal Observatory and has obtained its first engineering and calibration image...
COSINE-100 experiment investigates dark matter mystery
Dec 06, 2018 (SPX)
Astrophysical evidence suggests that the universe contains a large amount of non-luminous dark matter, yet no definite signal of it has been observed despite co...
Discovery of single material that produces white light could boost efficiency of LED bulbs
Dec 06, 2018 (SPX)
"Due to its high efficiency, this new material can potentially replace the current phosphors used in LED lights - eliminating the blue-tinged hue - and save ene...
Topping Off a Telescope with New Tools to Explore Dark Energy
Dec 05, 2018 (SPX)
DESI will create the largest 3-D map of the universe by gathering light from tens of millions of galaxies after its scheduled startup in late 2019. It is design...
The 'Camera That Saved Hubble' Turns 25
Dec 05, 2018 (JPL)
About the size of a school bus, the Hubble Space Telescope has an 8-foot (2.4-meter) primary mirror. The largest optical telescope ever launched into space, whe...
Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos
Dec 05, 2018 (SPX)
Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only kno...
Will light be the basis for quantum computing?
Dec 04, 2018 (SPX)
For nearly ten years, Professor Roberto Morandotti has been building an ambitious system piece by piece by developing chips that use light particles (photons) a...
Double Trouble: A White Dwarf Surprises Astronomers
Dec 04, 2018 (SPX)
In several billion years, our Sun will run out of most of its nuclear fuel and shrink down to a much smaller, fainter "white dwarf" star about the size of Earth...
IAU astronomers show exceptional involvement in outreach activities
Dec 03, 2018 (SPX)
A recently published study of the outreach activities of IAU members, Bustling public communication by astronomers around the world driven by personal and conte...
Newly discovered supernova complicates origin story theories
Dec 03, 2018 (SPX)
Their findings are published in a trio of papers in The Astrophysical Journal and The Astrophysical Journal Letters. Type Ia supernovae are fundamental to our u...
Newly discovered supernova may rewrite exploding star origin theories
Dec 03, 2018 (SPX)
This category of supernova, called "Type Ia," is fundamental to our understanding of the cosmos. Their nuclear furnaces are crucial for generating many of the e...
Kepler's supernova experiment captures first moments of dying star
Dec 03, 2018 (SPX)
NASA's Kepler space telescope detected the unfurling light of SN 2018oh, as it has been labeled. The first ground-based facility to identify the signal was with...
Fermi Traces the History of Starlight Across the Cosmos
Nov 30, 2018 (SPX)
"Stars create most of the light we see and synthesize most of the universe's heavy elements, like silicon and iron," said lead scientist Marco Ajello, an astrop...
Powerful Telescope to Explore 'Cosmic Dawn' from Chilean Peak
Nov 30, 2018 (SPX)
The 6-meter aperture telescope will be installed near the top of Cerro Chajnantor, a peak in Chile's Atacama Desert. CCAT-p will provide insights into "cosmic d...
Hubble Uncovers Thousands of Globular Star Clusters Scattered Among Galaxies
Nov 30, 2018 (SPX)
The survey, published in the November 9, 2018, issue of The Astrophysical Journal, will allow for astronomers to use the globular cluster field to map the distr...
Magnetic Fields Found in Jet from Baby Star
Nov 30, 2018 (SPX)
Jet is believed to play an important role in star formation, enabling the protostar to accrete mass from an accretion disk by carrying away angular momentum fro...
New device widens light beams by 400 times
Nov 29, 2018 (SPX)
Wider light beams could boost the speed and sensitivity of medical imaging and diagnostic procedures, security systems that detect trace amounts of toxic or vol...
Atomic jet - the first lens for extreme-ultraviolet light developed
Nov 29, 2018 (SPX)
A tree trunk partly submerged in water appears to be bent. Since hundreds of years people know that this is caused by refraction, i.e. the light changes its dir...
