|Water found on asteroid, confirming Bennu as excellent mission target|
Spectral observations made by the OSIRIS-REx spacecraft identified hydrated minerals across the asteroid, confirming that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study the composition of primitive volatiles and organics.

Solar activity research provides insight into sun's past, future
Scientists have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the sun's past and future as well as whether solar activity plays a role in climate change.

Evidence for carbon-rich surface on Ceres
Astronomers have concluded that the surface of dwarf planet Ceres is rich in organic matter. Data from NASA's Dawn spacecraft indicate that Ceres's surface may contain several times the concentration of carbon than is present in the most carbon-rich, primitive meteorites found on Earth.

NASA's Voyager 2 probe enters interstellar space
For the second time in history, a human-made object has reached the space between the stars. NASA's Voyager 2 probe now has exited the heliosphere -- the protective bubble of particles and magnetic fields created by the Sun.

NASA InSight lander 'hears' Martian winds
NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport InSight lander, which touched down on Mars just 10 days ago, has provided the first ever "sounds" of Martian winds on the Red Planet.

NASA's Mars InSight flexes its arm
New images from NASA's Mars InSight lander show its robotic arm is ready to do some lifting. With a reach of nearly 6 feet (2 meters), the arm will be used to pick up science instruments from the lander's deck, gently setting them on the Martian surface at Elysium Planitia, the lava plain where InSight touched down on Nov. 26.

Planetary defense: The Bennu experiment
On Dec. 3, after traveling billions of kilometers from Earth, NASA's OSIRIS-REx spacecraft reached its target, Bennu, and kicked off a nearly two-year, up-close investigation of the asteroid. It will inspect nearly every square inch of this ancient clump of rubble left over from the formation of our solar system. Ultimately, the spacecraft will pick up a sample of pebbles and dust from Bennu's surface and deliver it to Earth in 2023.

Magnetic reconnection in space: Experiment and satellite sightings
New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.

An exoplanet inflated like a balloon
Although helium is a rare element on Earth, it is ubiquitous in the universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only detected recently in the atmosphere of a gaseous giant by an international team. The team has observed for the first time how this gas escapes from the overheated atmosphere of an exoplanet, literally inflated with helium.

Mice display altered immune system following spaceflight
Based on examinations of mice that had been on board the Bion-M1 biosatellite, new research demonstrates that the outer space environment impairs the production of B lymphocytes, the white blood cells responsible for antibody production. The study also shows that such adverse effects persist at least one week after returning to Earth.

Mantle neon illuminates Earth's formation
The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, based on neon isotopes from the depths of the Earth and deep space. Apart from settling Earth's origins, the work could help in identifying extrasolar systems that could support habitable planets.

Tissue chips rocket to International Space Station
Scientists have recently sent tissue chips, a research technology that reflects the human body, into space. On Dec. 4, the first set of NIH-funded tissue chips that model aspects of the human immune system will launch on SpaceX's 16th commercial resupply mission (awarded by NASA) from Cape Canaveral, Florida, to the ISS National Lab.

Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos
New research could shed light on the 'missing' dark matter and dark energy that make up 95 percent of our universe and yet are wholly invisible to us.

NASA's OSIRIS-REx spacecraft arrives at asteroid Bennu
NASA's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft completed its 1.2 billion-mile (2 billion-kilometer) journey to arrive at the asteroid Bennu Monday. The spacecraft executed a maneuver that transitioned it from flying toward Bennu to operating around the asteroid.

Combination of space-based and ground-based telescopes reveals more than 100 exoplanets
Astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

Macroscopic phenomena governed by microscopic physics
Researchers have observed a magnetic reconnection driven by electron dynamics in laser-produced plasmas. Magnetic reconnections are often observed in the magnetic flux on the Sun and the Earth's magnetosphere. It has been highly challenging to reveal the electron scale, microscopic information in the vast universe. Applying a weak magnetic field, where only electrons are directly coupled with the magnetic field, we observed a plasmoid and cusp-like features typical to magnetic reconnections.

To image leaky atmosphere, NASA rocket team heads north
Earth's atmosphere is leaking, but how does oxygen get the energy to escape to space? NASA's VISIONS-2 rocket will soon launch into the unique magnetic environment near the North Pole in pursuit of an answer.

Mars new home 'a large sandbox'
With InSight safely on the surface of Mars, the mission team at NASA's Jet Propulsion Laboratory in Pasadena, California, is busy learning more about the spacecraft's landing site. They knew when InSight landed on Nov. 26 that the spacecraft had touched down on target, a lava plain named Elysium Planitia. Now they've determined that the vehicle sits slightly tilted (about 4 degrees) in a shallow dust- and sand-filled impact crater known as a "hollow." InSight has been engineered to operate on a surface with an inclination up to 15 degrees.

Newly discovered supernova complicates origin story theories
A supernova discovered by an international group of astronomers provides an unprecedented look at the first moments of a violent stellar explosion. The light from the explosion's first hours showed an unexpected pattern, which astronomers analyzed to reveal that the genesis of these phenomena is even more mysterious than previously thought.
