A nearby river of stars
Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.

Insulating crust kept cryomagma liquid for millions of years on nearby dwarf planet
A recent NASA mission to the dwarf planet Ceres found brilliant, white spots of salts on its surface. New research delved into the factors that influenced the volcanic activity that formed the distinctive spots and that could play a key role in mixing the ingredients for life on other worlds.

Possibility of recent underground volcanism on Mars
New research suggests liquid water is present beneath the south polar ice cap of Mars. Now, a new study argues there needs to be an underground source of heat for liquid water to exist underneath the polar ice cap.

Developing a flight strategy to land heavier vehicles on Mars
The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton, about 2,200 pounds. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. To do that, we need to figure out how to land more mass. That was the goal of a recent study.

Chang'e 4 Rover comes into view
The Lunar Reconnaissance Orbiter got a closer look at Chang'e 4 on the lunar far side. This time the small Yutu-2 rover shows up (two pixels) just north of the lander. Also, shadows cast by the lander and rover are now visible.

Shedding light on the science of auroral breakups
Scientists have quantitatively confirmed how energetic an auroral breakup can be. Using a combination of cutting-edge ground-based technology and new space-borne observations, they have demonstrated the essential role of an auroral breakup in ionizing the deep atmosphere. The research furthers our understanding of one of the most visually stunning natural phenomena.

A thousand new objects and phenomena in night sky
The Zwicky Transient Facility, based at the Palomar Observatory, has identified over a thousand new objects and phenomena in the night sky, including more than 1,100 new supernovae and 50 near-Earth asteroids. The alert system informs science teams of possible new objects or changes to known objects in the sky.

New technology helps address big problems for small satellites
The small size and relatively low cost of CubeSats have made them a popular choices for commercial launches in recent years, but the process to propel such satellites in space comes with a number of problems. Researchers have developed a technology to address one key problem - the uncertainty of ignition system that initiates the propulsion system of the CubeSats. Current ignition systems are unreliable and can be subject to significant and irreversible damage.

Bubbles of brand new stars
This dazzling region of newly forming stars in the Large Magellanic Cloud (LMC) was captured by the Multi Unit Spectroscopic Explorer instrument (MUSE) on ESO's Very Large Telescope. The relatively small amount of dust in the LMC and MUSE's acute vision allowed intricate details of the region to be picked out in visible light.

Scientists study organization of life on a planetary scale
In astrobiology, there is an increasing interest in whether life as we know it is a quirk of the particular evolutionary history of the Earth or, instead, if life might be governed by more general organizing principles.
