HEIC 1716 is bursting with starbirth
Oct 03, 2017 (ESA)
Compared to the other fundamental forces in the Universe, gravity is fairly weak. Despite this, gravity has an influence over huge distances and is the driving ...
Astronomers detect Freon-40 around infant stars, comet
Oct 01, 2017 (UPI)
Freon-40, also known as chloromethane, belongs to a class of molecules called organohalogens. The radio telescopes at the ALMA observatory in Chile are the firs...
NASA pushes back launch date for James Webb Space Telescope
Sep 29, 2017 (UPI)

New supernova analysis reframes dark energy debate
Sep 27, 2017 (SPX)
Dark energy is usually assumed to form roughly 70% of the present material content of the Universe. However, this mysterious quantity is essentially a place-hol...
New Mirror-Coating Technology Promises Dramatic Improvements in Telescopes
Sep 27, 2017 (SPX)
"It turns out that improving the performance of mirrors is all about thin-film materials, and that's what I do. So then I got hooked," said Kobayashi, a profess...
IceCube helps demystify strange radio bursts from deep space
Sep 26, 2017 (SPX)
The phenomena, known as fast radio bursts or FRBs, were first detected in 2007 by astronomers scouring archival data from Australia's Parkes Telescope, a 64-met...
New type of supercomputer could be based on 'magic dust' combination of light and matter
Sep 26, 2017 (SPX)
The researchers, from Cambridge, Southampton and Cardiff Universities in the UK and the Skolkovo Institute of Science and Technology in Russia, have used quantu...
Oxygen-deficient dwarf galaxy hints at makings of early universe
Sep 26, 2017 (SPX)
Their new finding, published in the journal Monthly Notices of the Royal Astronomical Society, shows that the oxygen level in the little galaxy is the lowest ye...
Researchers demonstrate quantum teleportation of patterns of light
Sep 25, 2017 (SPX)
To make it secure and fast requires a higher-dimensional alphabet, for example, using patterns of light, of which there are an infinite number. One such pattern...

Sep 24, 2017 (SPX)
The CNRS is the observatory's principal French funding agency. The discovery is published in the journal Science dated 22 September 2017 by an international col...
Study confirms cosmic rays have extragalactic origins
Sep 22, 2017 (SPX)
In an article to be published Sept. 22 in the journal Science, a group of more than 400 scientists from 18 nations describe how they detected an anisotropy, an ...
Detecting cosmic rays from a galaxy far, far away
Sep 22, 2017 (SPX)
The article, titled "Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 + 1018 eV", notes that studying the distribution o...
NASA using light to align the primary mirror segments of Webb Telescope
Sep 21, 2017 (SPX)
Part of the Webb telescope's ongoing cryogenic testing in Chamber A at Johnson includes aligning, or "phasing," the telescope's 18 hexagonally shaped primary mi...
Molecular motors: Slowing the clockwork
Sep 21, 2017 (SPX)
LMU chemists led by Dr. Henry Dube have developed a new method to synthesize a next generation of molecular motors. Using this method "we were able to reduce th...
Is the Milky Way an outlier galaxy
Sep 21, 2017 (SPX)
The Milky Way, which is home to Earth and its solar system, is host to several dozen smaller galaxy satellites. These smaller galaxies orbit around the Milky Wa...
Study shows star formation influenced by environmental conditions
Sep 15, 2017 (UPI)
According to the classical model, a star is formed when a prestellar core, a roundish accumulation containing 99 percent gas and 1 percent dust, collapses due t...
Keeping NASA's James Webb Space Telescope in the dark
Sep 13, 2017 (SPX)
Because of the Webb telescope's extreme sensitivity to infrared light, the shroud was made nearly impervious to outside light sources that could contaminate the...
