Sun: Igniting a solar flare in the corona with lower-atmosphere kindling
Recent images have revealed the emergence of small-scale magnetic fields in the lower reaches of the corona researchers say may be linked to the onset of a main flare.

How a young-looking lunar volcano hides its true age
A young-looking volcanic caldera on the Moon has been interpreted by some as evidence of relatively recent lunar volcanic activity, but new research suggests it's not so young after all.

Astronomers probe swirling particles in halo of starburst galaxy
Astronomers have used a radio telescope in outback Western Australia to see the halo of a nearby starburst galaxy in unprecedented detail.

From the room next door to the next planet over
The new Albert Chadwick Research Room inside the Roberts Proton Therapy Center is no ordinary laboratory space. In fact, there’s nothing else quite like it anywhere else in the United States, and whether it’s treating patients with cancer or helping NASA with its plans to send astronauts to Mars, the discoveries that could propel scientists forward will happen right here.

Timing a space laser with a NASA-style stopwatch
To time how long it takes a pulse of laser light to travel from space to Earth and back, you need a really good stopwatch -- one that can measure within a fraction of a billionth of a second. That kind of timer is exactly what engineers have built at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Ice, Cloud and land Elevation Satellite-2.

Stars born in winds from supermassive black holes
Observations using ESO's Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment. The discovery has many consequences for understanding galaxy properties and evolution.

Planetary waves, first found on Earth, are discovered on sun
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the sun, according to a new study.

NASA spacecraft investigate clues in radiation belts
NASA's Van Allen Probes uncover new phenomena in our near-Earth environment with their unique double orbit. Recently, the spacecraft were in just the right place, at just the right time, to catch an event caused by the fallout of a geomagnetic storm as it happened.

Astronomers identify purest, most massive brown dwarf
Astronomers have identified a record breaking brown dwarf (a star too small for nuclear fusion) with the 'purest' composition and the highest mass yet known. The object, known as SDSS J0104+1535, is a member of the so-called halo -- the outermost reaches -- of our galaxy, made up of the most ancient stars.

Gravitational wave kicks monster black hole out of galactic core
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of the distant galaxy 3C 186. The black hole was most likely ejected by the power of gravitational waves.

Astronomers find unexpected, dust-obscured star formation in distant galaxy
Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, astronomers report that they have detected a surprising rate of star formation, four times higher than previously detected, in a dust-obscured galaxy behind a Frontier Fields cluster.

Tracing aromatic molecules in the early Universe
A molecule found in car engine exhaust fumes that is thought to have contributed to the origin of life on Earth has made astronomers heavily underestimate the amount of stars that were forming in the early Universe, a study has found. That molecule is called polycyclic aromatic hydrocarbon. On Earth it is also found in coal and tar. In space, it is a component of dust.

Upper part of Earth’s magnetic field reveals details of a dramatic past
Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about the Earth’s crust. The result is the release of highest resolution map of this field seen from space to date. This ‘lithospheric magnetic field’ is very weak and therefore difficult to detect and map from space. But with the Swarm satellites it has been possible.

Comet 67P full of surprises: Growing fractures, collapsing cliffs and rolling boulders
Images returned from the European Space Agency's Rosetta mission indicate the surface of comet 67P/Churyumov-Gerasimenko was a very active place during its most recent trip through the solar system, says a new study.

Looking for signs of the Big Bang in the desert
The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand meters for the purposes of studying primordial gravitational waves which originated in the first instants of the Big Bang.

When helium behaves like a black hole
A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space -- is also true for cold helium atoms that can be studied in laboratories. This finding may be a step toward a long-sought quantum theory of gravity and new advances in quantum computing.

Astronomers hazard a ride in a 'drifting carousel' to understand pulsating stars
What sounds like a stomach-turning ride at an amusement park might hold the key to unraveling the mysterious mechanism that causes beams of radio waves to shoot out from pulsars -- super-magnetic rotating stars in our galaxy.

Mars volcano, Earth's dinosaurs went extinct about the same time
Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct.

Does Mars have rings? Not right now, but maybe one day
Researchers have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon.

Less radiation in inner Van Allen belt than previously believed
The inner Van Allen belt has less radiation than previously believed, according to a recent study. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.
