Solar wind samples suggest new physics of massive solar ejections

A new study led by the University of Hawai'i (UH) at Mānoa has helped refine understanding of the amount of hydrogen, helium and other elements present in violent outbursts from the Sun, and other types of solar "wind," ...

Status update: OSIRIS-REx Osprey Flyover

NASA's OSIRIS-REx spacecraft safely executed a 0.4-mile (620-m) flyover of the backup sample collection site Osprey as part of the mission's Reconnaissance B phase activities. Preliminary telemetry, however, indicates that ...

Galactic cosmic rays affect Titan's atmosphere

Planetary scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) revealed the secrets of the atmosphere of Titan, the largest moon of Saturn. The team found a chemical footprint in Titan's atmosphere indicating ...

Images: The two halves of Mars' whole

Mars is very much a world of two halves, as this new image from ESA's Mars Express highlights, showing where these dramatically different regions come together as one.

NASA's Mars 2020 rover goes coast-to-coast to prep for launch

NASA's next Mars rover has arrived in Florida to begin final preparations for its launch to the Red Planet this July. Two Air Force C-17 Globemaster cargo planes carrying the Mars 2020 rover as well as the cruise stage, descent ...

Image: 'Pale Blue Dot' revisited

For the 30th anniversary of one of the most iconic views from the Voyager mission, NASA's Jet Propulsion Laboratory in Pasadena, California, is publishing a new version of the image known as the "Pale Blue Dot."

New models hint at longer timescale for Mars formation

The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists ...

Astronomers discover potential near earth objects

Three astronomers from Leiden University (the Netherlands) have shown that some asteroids that are considered harmless for now can collide with the earth in the future. They did their research with the help of an artificial ...

Hackers could shut down satellites–or turn them into weapons

Last month, SpaceX became the operator of the world's largest active satellite constellation. As of the end of January, the company had 242 satellites orbiting the planet with plans to launch 42,000 over the next decade. ...

Video: Lagrange mission to provide solar warning

Earth's magnetic field protects life on Earth from the intense radiation and titanic amounts of energetic material our Sun blasts in every direction. However, astronauts and satellites in space, future explorers travelling ...

Ten things we've learned about the sun from NASA's SDO this decade

In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives ...

Astronomers have serious concerns about satellite constellations

Picture the space around Earth filled with tens of thousands of communications satellites. That scenario is slowly coming into being, and it has astronomers concerned. Now, a group of astronomers has written a paper outlining ...

Asteroid experts catch final glimpse of Solar Orbiter

Last night, ESA's Planetary Defence team observed the rare moment in which an object escaped our planet's gravity, in contrast to their normal objects of study—potentially hazardous rocks that could strike it.

Study reveals details of 'golf ball asteroid'

Asteroids come in all shapes and sizes, and now astronomers at MIT and elsewhere have observed an asteroid so heavily cratered that they are dubbing it the "golf ball asteroid."
