Hubble survey unlocks clues to star birth in neighboring galaxy
Sep 04, 2015 (SPX)
In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M3...
Cosmic recycling at the Prawn Nebula
Sep 03, 2015 (SPX)

Scientists 'squeeze' light one particle at a time
Sep 02, 2015 (SPX)
A team of scientists has successfully measured particles of light being "squeezed", in an experiment that had been written off in physics textbooks as impossibl...
Abell 1033 suggests giant collision triggered Radio Phoenix
Aug 31, 2015 (SPX)
Astronomers have found evidence for a faded electron cloud "coming back to life," much like the mythical phoenix, after two galaxy clusters collided. This "radi...
Astronomers unravel the history of galaxies for the first time
Aug 31, 2015 (SPX)
A team of international scientists, led by astronomers from Cardiff University's School of Physics and Astronomy, has shown for the first time that galaxies can...

Dying Star Suffers Irregular Heartbeats
Aug 26, 2015 (SPX)
Some dying stars suffer from 'irregular heartbeats', research led by astronomers at the University of Warwick has discovered. The research confirms rapid bright...
Gaia's first year of scientific observations
Aug 26, 2015 (ESA)
Last Friday, 21 August, ESA's billion-star surveyor, Gaia, completed its first year of science observations in its main survey mode. After launch on 19 December...
A detector shines in search for dark matter
Aug 21, 2015 (SPX)
Results of the XENON100 experiment are a bright spot in the search for dark matter. The team of international scientists involved in the project demonstrated th...
Physicists test theories of dark energy by mimicking the vacuum of space
Aug 21, 2015 (SPX)
Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energ...
Detecting dark matter might need a different approach
Aug 21, 2015 (SPX)
Physicists suggest a new way to look for dark matter: They believe that dark matter particles annihilate into so-called dark radiation when they collide. If tru...
Searching for ingredients of dark matter and dark energy
Aug 21, 2015 (SPX)
Two new reports advance efforts to identify components of dark matter and energy, which together comprise about 95% of the universe yet leave much to scientists...
Experiment attempts to snare a dark energy 'chameleon'
Aug 21, 2015 (SPX)
If dark energy is hiding in our midst in the form of hypothetical particles called "chameleons," Holger Muller and his team at the University of California, Ber...
The tumultuous heart of our Galaxy
Aug 21, 2015 (ESA)
