Asteroids worth getting psyched about
New discoveries from Ryugu, material heading our way from Bennu, and anticipation for a mission to Psyche.
What the search for aliens can learn from life on Earth
When searching for extraterrestrial life, we have to base our hunt on what we know about life on our own planet. This may seem limiting, but there's a lot we can learn from the astonishingly diverse lifeforms we have here on Earth.
The Planetary Society’s Space Book Club
Announcing a new space book club, where Planetary Society members can discuss great books and connect directly with authors and other experts.
Volcanic Venus, myriad moons, and space sonification
Learn all about the possible volcanic activity found on Venus, the facts about a hyped-up near-Earth asteroid, Jupiter’s newest moons, and what space images sound like.
NASA’s 2024 budget proposal is pretty good, but it faces political headwinds
The requested $27.2 billion would keep all major human and robotic initiatives going forward, though most of it would be offset by inflation.
Scientists spot possible signs of active volcanism on Venus
The findings bolster long-held suspicions that the planet, which is covered in volcanic rock, is still active today.
The secrets of Jupiter’s tiny new moons
Jupiter's 92 confirmed moons can teach us how the giant planets formed, and what conditions were like in the early Solar System.
Spectacularly crepuscular!
Curiosity captures crepuscular rays on Mars, a new member community launches, and solar sailing takes exploration into the future.
Welcome to your member community!
The Planetary Society has a new virtual space for members to connect and work together to advance space science and exploration.

Red hot space
This week’s roundup of space news and exploration inspiration will leave you seeing red (in the best way possible).
Why we need the NEO Surveyor space telescope
A space-based solution like NEO Surveyor will find more asteroids, more quickly, than any ground-based alternative. Combined with deflection technology, this gives humanity a chance to alter its fate should a threatening asteroid be found early enough.
Weaving together a picture of the Cosmos
When we combine data sources, collaborate with each other, and invite artistic perspectives, we can better understand the Universe we live in.
What was the Chelyabinsk meteor event?
When an asteroid exploded in the atmosphere above Chelyabinsk, Russia on Feb. 15, 2013, it made history and underscored the importance of planetary defense.
What does a bear have in common with a megatsunami?
An old image of Mars drives scientific questions today, moons and mini asteroids fuel fascination, and an unexpected ursine figure shows itself.
