Bright areas on Ceres suggest geologic activity
If you could fly aboard NASA's Dawn spacecraft, the surface of dwarf planet Ceres would generally look quite dark, but with notable exceptions. These exceptions are the hundreds of bright areas that stand out in images Dawn has returned. Now, scientists have a better sense of how these reflective areas formed and changed over time -- processes indicative of an active, evolving world.

Hubble's celestial snow globe
It's beginning to look a lot like the holiday season in this Hubble Space Telescope image of a blizzard of stars, which resembles a swirling snowstorm in a snow globe. The stars are residents of the globular star cluster Messier 79 (also known as M79 or NGC 1904), located 41,000 light-years from Earth, in the constellation Lepus.

Electrical and chemical coupling between Saturn and its rings
A Langmuir probe, flown to Saturn on the Cassini spacecraft, has made exciting discoveries in the atmosphere of the planet. They discovered that there is a strong coupling, both chemically and electrically, between the atmosphere of Saturn and its rings.

Life's building blocks observed in spacelike environment
Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility is that they originated in space, possibly within our solar system. A new study shows that a number of small organic molecules can form in a cold, spacelike environment full of radiation.

Telescopes team up to study giant galaxy
Astronomers have used two Australian radio telescopes and several optical telescopes to study complex mechanisms that are fuelling jets of material blasting away from a black hole 55 million times more massive than the Sun.

Unravelling the mysteries of extragalactic jets
Researchers have mathematically examined plasma jets from supermassive black holes to determine why certain types of jets disintegrate into huge plumes.

Black holes' magnetism surprisingly wimpy
Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light. It turns out the reality may not live up to the hype.

Galaxy growth in a massive halo in the first billion years of cosmic history
Observations of two galaxies made with the National Science Foundation-funded Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope suggest that large galaxies formed faster than scientists had previously thought.

Mars' atmosphere well protected from the solar wind
Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using measurements from the Swedish particle instrument ASPERA-3 on the Mars Express spacecraft.

NASA's SuperTIGER balloon flies again to study heavy cosmic particles
A science team in Antarctica is preparing to fly SuperTIGER, a balloon-borne instrument designed to collect heavy high-energy particles from beyond the solar system that constantly bombard Earth's atmosphere.

Clay minerals on Mars may have formed in primordial steam bath
New research suggests that the bulk of clay minerals on Mars could have been formed as the planet's crust cooled and solidified, not by later interactions with water on the surface as has long been assumed.

ALMA finds massive primordial galaxies swimming in vast ocean of dark matter
New observations push back the epoch of massive-galaxy formation even further by identifying two giant galaxies seen when the universe was only 780 million years old, or about 5 percent its current age.

NASA telescope studies quirky comet 45P
When comet 45P zipped past Earth early in 2017, researchers observing from NASA's Infrared Telescope Facility, or IRTF, in Hawai'i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial details about ices in Jupiter-family comets and reveal that quirky 45P doesn't quite match any comet studied so far.

Two Super-Earths around red dwarf K2-18
New research has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the planet has a neighbor.

WASP-18b has smothering stratosphere without water
Scientists have found evidence that the oversized planet WASP-18b is wrapped in a smothering stratosphere loaded with carbon monoxide and devoid of water.

The bacterial community on the International Space Station resembles homes
Microbiologists have analyzed swabs taken by astronauts on the International Space Station (ISS) and compared them with samples from homes on earth as well as the Human Microbiome Project. This work, part of a nationwide citizen science project called Project MERCCURI, found that the microbial community in this unique habitat was very diverse and more closely resembled that of homes than of humans.

Astronomer's map reveals location of mysterious fast-moving gas
The most detailed map ever of clouds of high-velocity gas in the universe around us has now been developed by scientsits. The map covers the entire sky and shows curious clouds of neutral hydrogen gas that are moving at a different speed to the normal rotation of the Milky Way.

Voyager 1 fires up thrusters after 37 years
A set of thrusters aboard the Voyager 1 spacecraft successfully fired up Wednesday after 37 years without use. Since 2014, engineers have noticed that the thrusters Voyager 1 has been using to orient the spacecraft, called "attitude control thrusters," have been degrading.
