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.

The electric sands of Titan
Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.

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.

Milky Way-like galaxies in early universe embedded in 'super halos'
Astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age.

New portal to unveil the dark sector of the universe
Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists catalogued 17 types of visible particles, with the most recent one being the Higgs boson, creating the 'Standard Model'. However, they are still struggling to detect the hidden particles, the ones that constitute the dark sector of the Universe.

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.

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.

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.

Eruptions on the sun trigger surprising phenomenon near Earth
Eruptions on the Sun's surface not only send bursts of energetic particles into the Earth's atmosphere causing disturbances in our planet's magnetic field, they can also strangely decrease the number of free electrons over large areas in the polar region of the ionosphere, new research concludes.

Scientists make the case to restore Pluto's planet status
Kirby Runyon wants to make one thing clear: regardless of what one prestigious scientific organization says to the contrary, Pluto is a planet. So, he says, is Europa, commonly known as a moon of Jupiter, and so is the Earth's moon, and so are more than 100 other celestial bodies in our solar system that are denied this status under the prevailing definition of 'planet.'

The rotation axes of stars tell us about how they were born
Using asteroseismology, an international research team has discovered a surprising alignment of the rotation axes of stars in open clusters, shedding light on the conditions in which stars are formed in our galaxy. Using data from Nasa’s Kepler mission, this result was obtained by studying a group of red giants in two old open clusters in the Milky Way.

Gigantic Jupiter-type planet reveals insights into how planets evolve
A team of astrophysicists studying an enormous and bizarre young planet approximately 300 lights years from Earth has gained a rare glimpse into the final stages of planetary evolution. While astronomers think the vast majority of planets outside our solar system are inside their star system's vast dusty debris disk, this strange planet is far beyond the disk.

Dark matter less influential in galaxies in early universe
New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or 'normal' matter. This is in stark contrast to present-day galaxies, where the effects of mysterious dark matter seem to be much greater. This surprising result was obtained using ESO's Very Large Telescope and suggests that dark matter was less influential in the early universe than it is today.

Relativistic electrons uncovered with NASA's Van Allen Probes
Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's Van Allen Probes mission show that the fastest, most energetic electrons in the inner radiation belt are not present as much of the time as previously thought.

Radiation from nearby galaxies helped fuel first monster black holes
Researchers have shown how supermassive black holes may have formed in the early universe. They suggest that radiation from a neighboring galaxy could have shut down star-formation in a black-hole hosting galaxy, allowing the nascent black hole to rapidly put on weight.

Keeping liquids off the wall
On Earth, liquid flows downhill thanks to gravity. Creating an effective liquid fuel tank involves little more than putting a hole at the bottom of a container. That won't work in space, though. In microgravity, with no gravity to force liquids to the bottom of a container, they cling to its surfaces instead. The Slosh Coating investigation tests using a liquid-repellant coating inside a container to control the movement of liquids in microgravity.

Hubble dates black hole's last big meal
NASA's Hubble Space Telescope has found that the black hole at the center of our Milky Way galaxy ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas. After the meal, the engorged black hole burped out a colossal bubble of gas weighing the equivalent of millions of suns, which now billows above and below our galaxy's center.

The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, newly published research suggests that mysterious phenomena called fast radio bursts could be evidence of advanced alien technology.

In particular, it will help astronomers understand why there are so many more young radio galaxies than old.
