Sailing among the stars: how photons could revolutionize space flight
Jun 20, 2019 (AFP)
It's been the stuff of scientists' dreams for decades but has only very recently become a reality. The idea might sounds crazy: propelling a craft through the v...
eROSITA - the hunt for Dark Energy begins
Jun 19, 2019 (SPX)
The space telescope will use its seven X-ray detectors to observe the entire sky and search for and map hot sources such as galaxy clusters, active black holes,...
Cool halo gas caught spinning like galactic disks
Jun 19, 2019 (SPX)
The researchers used W. M. Keck Observatory to obtain the first-ever direct observational evidence showing that corotating halo gas is not only possible, but co...
American Astronomical Society to Acquire Sky and Telescope
Jun 19, 2019 (SPX)
ST's current owner, the magazine- and book-publishing company F+W Media, sought Chapter 11 bankruptcy protection in March 2019 after what court filings describe...
Does the Gas in Galaxy Clusters Flow Like Honey?
Jun 19, 2019 (SPX)
Galaxy clusters are comprised of three main components: individual galaxies, multimillion-degree gas that fills the space between the galaxies, and dark matter,...
Astronomers investigate invisible matter and the workings of the galactic ecosystem
Jun 19, 2019 (SPX)
Think again - roughly half of a galaxy's matter is invisible. But scientists have since discovered this missing mass in halos of cool gas surrounding galaxies. ...
ALMA finds earliest example of merging galaxies
Jun 18, 2019 (SPX)
Takuya Hashimoto, a postdoctoral researcher at the Japan Society for the Promotion of Science and Waseda University, and his team used ALMA to observe B14-65666...
Fermi mission reveals its highest-energy gamma-ray bursts
Jun 17, 2019 (SPX)
"Each burst is in some way unique," said Magnus Axelsson, an astrophysicist at Stockholm University in Sweden. "It's only when we can study large samples, as in...
A new study reveals 'hidden' phases of matter through the power of light
Jun 17, 2019 (SPX)
A new study finds that a metal oxide has a "hidden" phase, one that gives the material new, ferroelectric properties, the ability to separate positive and negat...
How NASA's Spitzer has stayed alive for so long
Jun 17, 2019 (JPL)
Managed and operated by NASA's Jet Propulsion Laboratory in Pasadena, California, Spitzer is a small but transformational observatory. It captures infrared ligh...
NASA's Webb sunshield undergoes rocket fitting, more testing
Jun 13, 2019 (SPX)
Since Webb is too large to fit inside a rocket in its "deployed," or operational, form, it will be tested in its folded-up, or "stowed," launch configuration th...
Crash with dark galaxy gave milky way ripples in outer disc
Jun 13, 2019 (SPX)
The Antlia 2 dwarf galaxy was discovered from the second data release of the European Space Agency's Gaia mission, which aims to chart a three-dimensional map o...
Rare 'Superflares' Could One Day Threaten Earth
Jun 12, 2019 (SPX)
These events occur when stars, for reasons that scientists still don't understand, eject huge bursts of energy that can be seen from hundreds of light-years awa...
How acids behave in ultracold interstellar space
Jun 10, 2019 (SPX)
Using spectroscopic analyses and computer simulations, they investigated the question of whether hydrochloric acid (HCl) does or does not release its proton in ...
TESS first light on stellar physics
Jun 06, 2019 (SPX)
5th of June 2019 - Using asteroseismic techniques, an international team searched for pulsations in a subsample of five thousand stars, from the 32 thousand obs...
How the Webb Telescope Will Explore Mars
Jun 06, 2019 (SPX)
When NASA's James Webb Space Telescope, launching in 2021, reaches its destination a million miles from Earth, it will be able to see the whole disk of Mars eve...
Accurate probing of magnetism with light
Jun 04, 2019 (SPX)
A team of researchers led by the Max Born Institute has now provided the experimental and theoretical groundwork to interpret such spectroscopic signals. The re...
Heart of Lonesome Galaxy Is Brimming with Dark Matter
Jun 04, 2019 (SPX)
Scientists have found that it has gone through a different evolution than typical galaxies, both in terms of its stars and the invisible dark matter that, throu...
Precision calibration empowers largest solar telescope
Jun 04, 2019 (SPX)
As with any astronomical instrument, calibration is required in order to remove effects that the instrument itself might have on the data. By concentrating on c...
