Meet the Habitable Worlds Observatory, NASA’s life-seeking telescope
The observatory will directly image Earth-size exoplanets circling other stars.
NASA's FY 2025 budget request is not enough
Federal spending caps and inflation take a bite out of NASA's ambitions.
Uranus' biggest unsolved mysteries
Distant, icy Uranus has puzzled scientists for decades. From its sideways spin to its mysterious magnetic field, the oddball world has many secrets waiting to be revealed.
Why the true colors of the planets aren't what you think
Cameras on our space probes act as proxies for our own eyes, but what they see isn't necessarily what our eyes would see.
Looking for long waves
Why JWST observes in the infrared.
See for yourself
See the month’s coolest space pictures, see planets in the night sky, and create the future in space that you want to see.
That’s a mare
An unusual lunar feature, Saturn’s shining rings, and Mars’ complex gullies.
Speedy spacecraft and pretty pics
Take a look at some of our favorite recent space images and learn about an express mission to Mars.
Searching the skies to keep us all alive
Astronomers around the world are working to protect the Earth from asteroid impacts, with the help of Planetary Society members and donors.
Day and night, it’s all about starlight
This week in space: Mars days almost match up with ours, and light and molecules are created by distant stars.
The scientific truth is out there
The real science of aliens, the policy implications of ET, and new views of worlds beyond our own.
Would you like some salty water with your space salad?
Two new grant-winning projects, a collection of awesome space imagery, a mighty plume, and much more this week in space.
Want more space? Speak up!
Detailed Mars maps, insights into the Venusian surface, and views of Uranian rings all have one thing in common: they don’t happen without public support for space.
A mission to pull back the shroud
VERITAS would peer through Venus’ clouds to study its surface like never before, but it needs your help.
Unusual Uranus! Moist Moon! Volcanic Venus!
A planet shows its pole, another shows possible volcanic activity, and the Moon keeps surprising us with more water.
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.
Spectacularly crepuscular!
Curiosity captures crepuscular rays on Mars, a new member community launches, and solar sailing takes exploration into the future.
Never let a rock sneak up on you
Finding asteroids before they hit Earth not only protects us from harm, it can also yield beautiful photos.
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.
