Coldest material in the cosmos could help scientists find dark matter particles
May 01, 2020 (UPI)
Roughly 80 percent of the cosmos is composed of material that exerts a gravitational influence on surrounding matter but does not interact with light. Astronome...
Hubble's impactful life alongside space debris
May 01, 2020 (ESA)
Hubble itself has felt the impact of this debris, accumulating tiny impact craters across its solar panels that evidence a long and eventful life in space. So w...
NASA's Swift Satellite Celebrates 15 Years of Multiwavelength Science
Apr 29, 2020 (SPX)
"Fifteen years since its launch, Swift continues to observe some of the most exciting events in the cosmos," said Paul Hertz, director of the Astrophysics Divis...
New metasurface laser produces world's first super-chiral light
Apr 28, 2020 (SPX)
"Because light can carry angular momentum, it means that this can be transferred to matter. The more angular momentum light carries, the more it can transfer. S...
An eclipsing binary millisecond pulsar discovered by FAST
Apr 28, 2020 (SPX)
Named as PSR J1717+4307A or M92A, it is the first pulsar known in M92, with a spinning period of 3.16 ms and a dispersion measure (DM) of 35.45 pc cm-3. Follow-...
Hubble marks 30 years in space with tapestry of blazing starbirth
Apr 28, 2020 (SPX)
In this Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic...
Large scale survey telescope to be built in northwest China
Apr 24, 2020 (XNA)
On April 16, the University of Science and Technology of China (USTC) signed a cooperation agreement with the Haixi Mongol and Tibetan autonomous prefecture in ...
The 'Camera That Saved Hubble'
Apr 24, 2020 (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...
New design could make fiber communications more energy efficient
Apr 23, 2020 (SPX)
The University of Pennsylvania, Peking University and Massachusetts Institute of Technology worked on a project funded, in part by the Army Research Office, whi...
Hungry galaxies grow fat on the flesh of their neighbors
Apr 23, 2020 (SPX)
Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation a...
Milky Way could be catapulting stars into its outer halo, UCI astronomers say
Apr 21, 2020 (SPX)
Hyper-realistic, cosmologically self-consistent computer simulations from the Feedback in Realistic Environments 2 project enabled the scientists to model the d...
A tale of two telescopes: WFIRST and Hubble
Apr 21, 2020 (SPX)
Though it's often compared to the Hubble Space Telescope, which turns 30 years old this week, WFIRST will study the cosmos in a unique and complementary way. "W...
New photon-counting camera captures 3D images with record speed and resolution
Apr 17, 2020 (SPX)
"Thanks to its high resolution and ability to measure depth, this new camera could make virtual reality more realistic and let you interact with augmented reali...
Light from stretchable sheets of atoms for quantum technologies
Apr 17, 2020 (SPX)
The ability to finely tune the colors of quantum light has been proposed as a key step in developing quantum network architectures,where photons, the fundamenta...
Beacon in space
Apr 16, 2020 (SPX)
Since the beginning of the BRITE Constellation in 2013 - a mission in which the first two Austrian satellites were involved - the five nanosatellites have taken...
Satellite galaxies of the Milky Way help test dark matter theory
Apr 16, 2020 (SPX)
Using sophisticated simulations, the researchers show a theory called self-interacting dark matter, or SIDM, can compellingly explain diverse dark matter distri...
Seeing the light: MSU research finds new way novae light up the sky
Apr 15, 2020 (SPX)
The explosion occurs when a white dwarf star strips material from its companion star that piles up on the dwarf's surface, eventually triggering a thermonuclear...
Astronomers detect most energetic outflow from a distant quasar
Apr 15, 2020 (SPX)
The most energetic wind from a quasar has been revealed by a team of astronomers using observations from the international Gemini Observatory, a program of NSF'...
New formation theory explains the mysterious interstellar object 'Oumuamua
Apr 14, 2020 (SPX)
How was it formed, and where did it come from? A new study published April 13 in Nature Astronomy offers a first comprehensive answer to these questions. First ...
Scientists discover supernova that outshines all others
Apr 14, 2020 (SPX)
The team, which included experts from Harvard, Northwestern University and Ohio University, believe the supernova, dubbed SN2016aps, could be an example of an e...
