Europa Clipper is a big spacecraft with big solar panels, all so it can perform a big mission. The galaxy is big too, and a Planetary Society member painted it that way.

The “Wow!" signal has a new explanation, and an ultra-cool experiment advances quantum sensing in space. Plus, making an asteroid go “boom!” might work, depending on the circumstances.

When a skyscraper-sized asteroid narrowly misses Earth in 2029, three spacecraft may be along for the ride.

NASA is underfunding planetary exploration relative to recommendations made by the National Academies Decadal Survey report, resulting in mission delays and cancelations.

Detonating a nuclear weapon on or near an asteroid is one of several options for defending the Earth from an impact. Here's what nuking an asteroid might actually do, and why it isn't always the best option.

New research suggests liquid water might be hiding under the surface of Mars. Could life be there too?

With all the advances in private space exploration, why do taxpayers still pay for space science missions?

The tentative discovery hints at an habitat where life could potentially thrive.

From X-ray imaging to slithering beneath Enceladus’ crust, space technology is always expanding what we can see for ourselves.

The snake-like robot is being designed to autonomously navigate the challenging terrain of Saturn’s moon Enceladus, including descending into fissures in the moon’s icy crust. The skills it needs in order to explore this distant, unfamiliar world may make EELS well equipped to explore even more alien worlds, perhaps including exoplanets.

Knowing that you've found signs of life beyond Earth may not be as clear-cut and simple as one might think.

A big rover makes a big find on Mars. Little rovers have their place in exploration, too.

A single 3.5 billion-year-old rock shows signs of all the conditions life needs to thrive.

An analysis of the U.S. Senate's FY 2025 budget request for NASA.

Jupiter has often been thought to protect the inner Solar System from asteroids and comets, but new research has shown that the giant planet may actually increase the risk of an impact.

This was a big week in space, from Curiosity stumbling upon sulfur crystals to an exoplanet discovery and a major advocacy effort.

The gas giant is the Solar System's largest planet. Here's why it's also the fastest-spinning planet.

NASA has canceled VIPER, a rover designed to seek out water ice and other resources in the lunar south pole.

A comet collided with Jupiter 30 years ago, and the resulting images still inspire awe and wonder today.

One rocket could decide how soon humanity returns to the Moon — and maybe one day sets foot on Mars.
