Hubble sees Neptune's mysterious shrinking storm
Feb 16, 2018 (SPX)
Immense dark storms on Neptune were first discovered in the late 1980s by NASA's Voyager 2 spacecraft. Since then, only Hubble has had the sharpness in blue lig...
Physicists create new form of light
Feb 16, 2018 (SPX)

Milky Way ties with neighbor in galactic arms race
Feb 15, 2018 (SPX)
It had been thought that Andromeda was two to three times the size of the Milky Way, and that our own galaxy would ultimately be engulfed by our bigger neighbou...
Galaxies that feed on other galaxies
Feb 15, 2018 (SPX)
The method that was used, i.e. a spectroscopic analysis, consists in separating the light of the stars in its different frequencies in order to obtain informati...
The search for dark matter: Axions have ever fewer places to hide
Feb 15, 2018 (SPX)
The latest analysis of measurements of the electrical properties of ultracold neutrons published in the scientific journal Physical Review X has led to surprisi...
Astronomy: A rotating system of satellite galaxies raises questions
Feb 15, 2018 (SPX)
Like other large galaxies, our Milky Way is surrounded by smaller galaxies that orbit it as satellites. According to the standard model of cosmology that descri...
Astronomers Concerned with Proposed Cancellation of Space Telescope

Prototype dish for SKA super telescope assembled in China
Feb 12, 2018 (XNA)
The SKA, an international effort to build the world's largest radio telescope using arrays in Australia and South Africa, is not a single telescope, but a colle...
Cosmic x-rays may provide clues to the nature of dark matter
Feb 12, 2018 (SPX)
But to date and despite intensive research, it has proved impossible to actually identify the particles involved. Researchers at Johannes Gutenberg University M...
Clocking electrons racing faster than light in glass
Feb 09, 2018 (SPX)
Why is this question important? There are many reasons. Firstly, these electrons drive giant current pulses (millions of ampere) that can generate some of the m...
New use for telecommunications networks: Helping scientists peer into deep space
Feb 07, 2018 (SPX)
The ability to send stable frequency references over the telecommunications network could be particularly useful for radio telescope arrays such as the Square K...
Natural telescope sets new magnification record
Feb 02, 2018 (SPX)
Using the Hubble Space Telescope (HST) to survey a sample of huge clusters of galaxies, the team found a distant galaxy, eMACSJ1341-QG-1, that is magnified 30 t...
