Galactic cosmic rays now available for study on Earth, thanks to NASA
May 20, 2020 (SPX)
An article publishing on May 19, 2020 in the open access journal PLOS Biology from Lisa Simonsen and colleagues at the NASA Langley Research Center, USA, descri...
No evidence of an influence of dark matter on the force between nuclei
May 19, 2020 (SPX)
It is not yet known whether dark matter also interacts with itself or with normal matter via the other three fundamental forces - the electromagnetic force, the...
Surveying the gamma-ray sky continuously
May 19, 2020 (SPX)
More than two thousand sources were discovered since the previous catalog (3FGL) published in 2015. This improvement was made possible by doubling the observing...
NASA's James Webb Space Telescope fully stowed
May 15, 2020 (SPX)
Webb is NASA's largest and most complex space science telescope ever built. Too big for any rocket available in its fully expanded form, the entire observatory ...
Astronomers find regular rhythms among pulsating stars
May 14, 2020 (SPX)
"Previously we were finding too many jumbled up notes to understand these pulsating stars properly," said lead author Professor Tim Bedding from the University ...
NASA's TESS enables breakthrough study of perplexing stellar pulsations
May 14, 2020 (SPX)
"Delta Scuti stars clearly pulsate in interesting ways, but the patterns of those pulsations have so far defied understanding," said Tim Bedding, a professor of...
Where neutrinos come from
May 14, 2020 (SPX)
Cosmic neutrinos turned out to be linked to flares at the centers of distant active galaxies, which are believed to host supermassive black holes. As matter fal...
Mysterious delta Scuti stars start to surrender secrets
May 14, 2020 (SPX)
Pulsations are a common feature of stars. They are natural resonances, formed by trapped waves like those in musical instrument, and provide a unique way to loo...
Powerful new AI technique detects and classifies galaxies in astronomy image data
May 13, 2020 (SPX)
Morpheus is a deep-learning framework that incorporates a variety of artificial intelligence technologies developed for applications such as image and speech re...
Bending the bridge between two galaxy clusters
May 12, 2020 (SPX)
Galaxy clusters are the largest objects in the universe held together by gravity. They contain hundreds or thousands of galaxies, vast amounts of multi-million-...
How to manipulate light on the nanoscale over wide frequency ranges
May 11, 2020 (SPX)
Research with nanolight based on phonon polaritons has developed considerably in recent years thanks to the use of sheet-structured nanomaterials such as graphe...
South Africa's MeerKAT Solves Mystery of X-Galaxies
May 08, 2020 (SPX)
Several possible explanations have been proposed to understand this phenomenon. These include changes in the direction of spin of the black hole at the centre o...
NASA to demonstrate first-of-its-kind in-space manufacturing technique for telescope mirrors
May 06, 2020 (SPX)
A NASA engineer was selected for a flight opportunity to show that an advanced thin-film manufacturing technique called atomic layer deposition, or ALD, could a...
Age of NGC 6652 globular cluster specified
May 06, 2020 (SPX)
Globular clusters are mostly situated tens and hundreds of thousands of light years from Earth, and only the brightest stars in them can actually be studied. Ma...
Identifying light sources using artificial intelligence
May 06, 2020 (SPX)
In Applied Physics Reviews, from AIP Publishing, researchers demonstrated a smart quantum technology that enables a dramatic reduction in the number of measurem...
