Cameras on spacecraft are our eyes into the Cosmos. Sometimes they teach us things, sometimes they reveal gaps in our knowledge.

Weeks before the new fiscal year, Congress still hasn't finalized NASA's 2025 budget.

NASA is preparing to launch its flagship mission to explore Jupiter’s moon Europa. Launching as early as Oct. 10, 2024, and arriving in 2030, the mission will explore the icy world with a subsurface ocean that scientists think could have conditions favorable to life.

Life thrives on Earth, and we even send evidence of our presence out into the Solar System. Is anyone out there looking for us?

A Planetary Society-funded project to understand asteroids achieved its main goals and scientific objectives this year.

Looking at life on Earth from another perspective.

Looking to the past to guide the search for life.

Could the Solar System host traces of other intelligent life?

Exploring Europa and defending Earth.

From holes on Mars to a spun-around moon and a flipped reflection, space science involves looking at things from all different angles.

China is in the early stages of planning a huge space observatory to help answer the matter of whether we are alone in the galaxy.

The Planetary Society and Lerner Publishing Group have teamed up to bring young readers an engaging series of books that make space science fun and accessible.

The habitable zone is a useful concept in astrobiology, but it can sometimes paint an over-simplified picture of planetary habitability.

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?
