SDO reveals how magnetic cage on the Sun stopped solar eruption
A dramatic magnetic power struggle at the Sun's surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights the role of the Sun's magnetic landscape, or topology, in the development of solar eruptions that can trigger space weather events around Earth.

On second thought, the Moon's water may be widespread and immobile
A new analysis of data from two lunar missions finds evidence that the Moon's water is widely distributed across the surface and is not confined to a particular region or type of terrain. The water appears to be present day and night, though it's not necessarily easily accessible.

Dust dilemma settles on upcoming moon missions
The world's foremost authority on lunar dust is suggesting the powder-like substance, which is finer than talcum powder and more abrasive than sandpaper, remains a major risk-management problem hampering upcoming space expeditions.

Researcher sets eyes on Saturn's largest moon
Co-led by a Western space scientist, NASA is exploring a revolutionary plan that could see a drone-like quadcopter buzz above the surface of Saturn's largest moon.

Goonhilly antenna goes deep space
Until now, if you're an entrepreneur planning future missions beyond Earth, you'd have to ask a big space agency to borrow their deep-space antennas. Now, thanks to the UK's county of Cornwall and ESA, you'll have a commercial option, too.

Swarm trio becomes a quartet
With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora borealis.

Improved Hubble yardstick gives fresh evidence for new physics in the universe
Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.

SpaceX launches Spanish satellite, two others from California
An Earth-observation satellite built for Spain and two experimental satellites for internet service were successfully launched into orbit from California at dawn Thursday, creating a brief light show as it arced over the Pacific Ocean west of Los Angeles.

Image: Hypervelocity impact testing
What looks like a mushroom cloud turned sideways is actually the instant an 2.8 mm-diameter aluminium bullet moving at 7 km/s pierces a spacecraft shield, captured by a high-speed camera.

Magnetic field traces gas and dust swirling around supermassive black hole
Astronomers reveal a new high resolution map of the magnetic field lines in gas and dust swirling around the supermassive black hole at the centre of our Galaxy, published in a new paper in Monthly Notices of the Royal Astronomical Society. The team, led by Professor Pat Roche of the University of Oxford, created the map, which is the first of its kind, using the CanariCam infrared camera attached to the Gran Telescopio Canarias sited on the island of La Palma.

New atmosphere wind/temperature sensor to improve space weather prediction
Global wind and temperature measurements in the lower thermosphere (100-150 km above Earth) are the two most important variables needed to accurately predict space weather and climate change. An innovative technique is being developed jointly by the Johns Hopkins University Applied Physics Laboratory, GSFC, and JPL to make these measurements using the atomic oxygen emission at 2.06 THz (145 μm).

Co-evolution black hole mystery deepened by a new ALMA observation
Using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe an active galaxy with a strong ionized gas outflow from the galactic center, a team led by Dr. Yoshiki Toba of the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan) has obtained a result making astronomers even more puzzled—the team clearly detected carbon monoxide (CO) gas that is associated with the galactic disk, yet they have also found that the CO gas which settles in the galaxy is not affected by the strong ionized gas outflow launched from the galactic center.

Team publishes roadmap to enhance radioresistance for space colonization
An international team of researchers from NASA Ames Research Center, Environmental and Radiation Health Sciences Directorate at Health Canada, Oxford University, Canadian Nuclear Laboratories, Belgian Nuclear Research Centre, Insilico Medicine, the Biogerontology Research Center, Boston University, Johns Hopkins University, University of Lethbridge, Ghent University, Center for Healthy Aging and many others have published a roadmap toward enhancing human radioresistance for space exploration and colonization in the peer-reviewed journal Oncotarget.

Pulsating aurora mysteries uncovered with help from NASA's THEMIS mission
Sometimes on a dark night near the poles, the sky pulses a diffuse glow of green, purple and red. Unlike the long, shimmering veils of typical auroral displays, these pulsating auroras are much dimmer and less common. While scientists have long known auroras to be associated with solar activity, the precise mechanism of pulsating auroras was unknown. Now, new research, using data from NASA's Time History of Events and Macroscale Interactions during Substorms—or THEMIS—mission and Japan's Exploration of energization and Radiation in Geospace—shortened to ERG, or also known as Arase—satellite, has finally captured the missing link thought responsible for these auroras. The answer lies in chirping waves that rhythmically pulse the particles that create the auroras.

James Webb Space Telescope to reveal secrets of the Red Planet
The planet Mars has fascinated scientists for over a century. Today, it is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth's. But evidence suggests that in the early history of our solar system, Mars had an ocean's worth of water. NASA's James Webb Space Telescope will study Mars to learn more about the planet's transition from wet to dry, and what that means about its past and present habitability.

Lyman-alpha emission detected around quasar J1605-0112
Using the Multi Unit Spectroscopic Explorer (MUSE) instrument astronomers have discovered an extended and broad Lyman-alpha emission in the form of a nebula around the quasar J1605-0112. The finding is reported February 9 in a paper published on the arXiv pre-print repository.

'Ultramassive' black holes discovered in far-off galaxies
Thanks to data collected by NASA's Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists has detected what are likely to be the most massive black holes ever discovered in the universe. The team's calculations showed that these ultramassive black holes are growing faster than the stars in their respective galaxies.
