Astronomers smash cosmic records to see hydrogen in distant galaxy
Jun 06, 2016 (SPX)
An international team of scientists has pushed the limits of radio astronomy to detect a faint signal emitted by hydrogen gas in a galaxy more than five billion...
Meta-lens sees smaller than a wavelength of light
Jun 03, 2016 (SPX)
Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are ...
Elliptical galaxies not formed by merging
Jun 03, 2016 (SPX)
It all starts from a problem with dust: galaxies with the highest rates of star formation are also the "dustiest", because the violent process of star formation...
Measuring the Milky Way: 1 massive problem, 1 new solution
Jun 01, 2016 (SPX)
It is a galactic challenge, to be sure, but Gwendolyn Eadie is getting closer to an accurate answer to a question that has defined her early career in astrophys...
Blowing bubbles in the Milky Way's magnetic field
Jun 01, 2016 (SPX)
An international team of astronomers has discovered a possible connection between the magnetic fields of supernova remnants and that of our own Milky Way Galaxy...
The Little Fox and the Giant Stars
Jun 01, 2016 (JPL)
New stars are the lifeblood of our galaxy, and there is enough material revealed by this Herschel infrared image to build stars for millions of years to come. S...
The Galaxy Is Under Pressure to Make Stars
Jun 01, 2016 (SPX)
A new study led by Canadian astronomers provides unprecedented insights into the birth of stars. Using observations from the Green Bank Telescope in West Virgin...
Beating the limits of the light microscope, one photon at a time
May 31, 2016 (SPX)
The world's most advanced light microscopes allow us to see single molecules, proteins, viruses and other very small biological structures. But even the best mi...
Engineers discover a new gatekeeper for light
May 30, 2016 (SPX)
Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment. Such...
Astronomers Confirm Faintest Early-Universe Galaxy Ever Seen
May 26, 2016 (SPX)
An international team of scientists, including two professors and three graduate students from UCLA, has detected and confirmed the faintest early-universe gala...
A Young Mammoth Cluster of Galaxies Sighted in the Early Universe
May 26, 2016 (SPX)
Astronomers have uncovered evidence for a vast collection of young galaxies 12 billion light years away. The newly discovered "proto-cluster" of galaxies, obser...
Hunting for Dark Matter's Hidden Valley
May 25, 2016 (SPX)
Kathryn Zurek realized a decade ago that we may be searching in the wrong places for clues to one of the universe's greatest unsolved mysteries: dark matter. De...
Closing in on the elusive rotational-vibrational CH5+ spectra
May 25, 2016 (SPX)
Protonated methane, a.k.a. CH5+, is a highly unusual molecule that scientists and astronomers suspect may be found within the interstellar medium where stars an...
OU astrophysicists detect most luminous diffuse gamma-ray emission from Arp 220
May 25, 2016 (SPX)
A University of Oklahoma team has detected for the first time the most luminous gamma-ray emission from a galaxy--the merging galaxy Arp 220 is the nearest ultr...
