Massive dead disk galaxy challenges theories of galaxy evolution
By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.

Ten near-Earth size planets in habitable zone of their star
NASA's Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet.

Making waves with the hot electrons within Earth's radiation belts
An international team of scientists recently discovered the role that hot electrons may play in the waves and fluctuations detected by satellites. The results are based on data collected by the Van Allen Probes, twin robotic spacecraft launched by NASA in 2012 to help scientists better understand these belt regions.

A unique data center for cosmological simulations
Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

MAVEN's top 10 discoveries at Mars
Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

On the road to creating an electrodeless spacecraft propulsion engine
Researchers have been trying to find out how the plasma flow is influenced by its environment via laboratory experiments. And in doing so, have made headway on research towards creating an electrodeless plasma thruster used to propel spacecraft.

Low-mass stars always born with a sibling: Many, like our sun, split up
Though astronomers have long known that many if not most stars are binaries, the question has always been, Were they born that way, or did one star capture another? Astronomers teamed up to systematically study very young stars inside their nest eggs, called dense cores, in the Perseus molecular cloud and concluded that all sunlike stars are born as wide binaries. Most subsequently split up, while the rest become tight binaries.

Search for Earth-like planets: Try a statistical approach
A team of astronomers seeks to change the way scientists approach the search for Earth-like planets orbiting stars other than the sun. They favor taking a statistical comparative approach in seeking habitable planets and life beyond the solar system.

Cloudy with a chance of radiation: NASA studies simulated radiation
NASA's Human Research Program (HRP) is simulating space radiation on Earth following upgrades to the NASA Space Radiation Laboratory (NSRL) at the US Department of Energy's Brookhaven National Laboratory. These upgrades help researchers on Earth learn more about the effects of ionizing space radiation to keep astronauts safe on a journey to Mars.

Hot rocks, not warm atmosphere, led to relatively recent water-carved valleys on Mars
Some scientists have interpreted water-carved valleys on Mars formed within the last few billion years as a sign of either an active groundwater system or of transient warm periods in the atmosphere. But new research shows that snow and ice melted by hot impact ejecta could have produced enough water to carve those valleys with no groundwater or heat wave required.

Galaxy alignments traced back 10 billion years
The most massive galaxies in the universe have been aligned with their surroundings for at least ten billion years. This discovery shows that galaxies, like people, are influenced by their environment from a young age.

VST captures Eagle Nebula and close companions
Two of the sky's more famous residents share the stage with a lesser-known neighbor in an enormous new three gigapixel image from ESO's VLT Survey Telescope (VST). On the right lies Sharpless 2-54, the iconic Eagle Nebula is in the center, and the Omega Nebula to the left. This cosmic trio makes up just a portion of a vast complex of gas and dust within which new stars are springing to life and illuminating their surroundings.

ALMA hears birth cry of a massive baby star
Astronomers have determined how the enigmatic gas flow from a massive baby star is launched. The team used ALMA to observe the baby star and obtained clear evidence of rotation in the outflow. The motion and the shape of the outflow indicate that the interplay of centrifugal and magnetic forces in a disk surrounding the star plays a crucial role in the star's birth cry.
