Hubble traces the halo of a galaxy more accurately than ever before

Astronomers using the Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.

Transiting exoplanet with longest known year

Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods.

It's go time for LUX-Zeplin dark matter experiment

From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence. The US Department of Energy's Office of Science and the National Science Foundation recently gave the go-ahead to Large Underground Xenon-Zeplin, a key experiment in the hunt for dark matter, the invisible substance that may make up much of the universe.

Van Allen Probes show how to accelerate electrons

One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Recent data from the Van Allen Probes - two nearly identical spacecraft that launched in 2012 - address this question.
