CubeSat instrument extends solar storm warnings 10x

The sun is the reason life exists on our small, blue planet. It provides solar radiation that warms the planet and ignites intricate biochemical processes like photosynthesis, producing oxygen for life to breathe. However, ...

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 ...

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, ...

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 ...

What's carving active gullies on Mars? It's not water

Scientists were shocked when they received the first images of Martian gullies. They were even more shocked as those gullies appeared to change over time. Their similarities to gullies seen on Earth were uncanny, but all ...

Ancient Swedish Goths had surprisingly accurate calendars

On a mostly flat plain an hour north of Stockholm lies a collection of large burial mounds dating from an ancient culture at least 2,500 years old. These people were not Vikings; they were northern Germanic Goths, pagan polytheists ...

Sun's largest sunspots may have potential to trigger superflares

The sun is capable of great things. In massive eruptions, it repeatedly hurls particles and radiation into space. This solar bombardment can be dangerous for technical infrastructure on Earth: For example, satellites and ...

NASA Johnson pilots chase moon's shadow for eclipse science

During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the sun's outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant ...

Did ocean motion carve Enceladus's tiger stripes?

Saturn's moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers ...
