Laser altimeter BELA ready to explore Mercury's surface

Launched on Oct. 20, 2018, the joint ESA/JAXA BepiColombo mission has traveled for almost eight years, using a carefully planned but eventful sequence of planetary flybys and solar-electric propulsion to gradually approach ...

A new design for a plasma engine fuels on only thin air

Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and ...

How the 2024 solar superstorm drained Earth's radiation belt

In May 2024, Earth experienced its most intense geomagnetic storm since the Halloween storms of 2003. This "superstorm" filled night skies in many parts of the world with colorful aurorae, and it disrupted some infrastructure, ...

Dense galaxies are carving out a bubble in the early universe

When JWST's first science results started rolling in, it was a triumph for scientific vision and persistence. For years, the fate of the powerful space telescope was uncertain. It went way over budget, and for 25 years, troubling ...

Astronomers unmask a supernova impostor

A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is behind the star's outbursts. ...

Cataract surgery will be needed in space, surgeon predicts

An eye surgeon with a passion for space since childhood predicts that as astronauts start to make journeys to the moon and Mars in the near future, eye surgery in space will eventually become a necessity.

NASA's next great observatory could spot oceans on distant worlds

We've found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we've never definitively found a liquid ocean on another ...

NASA science soars during August total solar eclipse

Each time the moon covers the sun during a total solar eclipse—darkening daytime skies and briefly revealing the sun's ethereal outer atmosphere, the corona—it presents new opportunities to better understand our star and ...

JWST could spot volcanic 'exo-Ios' around super-Jupiters

Jupiter's moon Io is the most volcanically active planetary body in the solar system, boasting hundreds of active volcanoes that spew molten lava into space. This activity results from a process called tidal heating, in which ...

Hubble shows star formation in Andromeda galaxy is winding down

A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
