With space missions like JWST and Voyager, decades of development yield decades of discovery.
Feast your eyes on these images from space, catch up on the latest in exploration news, and get the lowdown on what’s up in the night sky.
The mission includes a flyby of Neptune and measurements of the heliosphere, the electrically charged gas bubble surrounding our solar system
The LSST is expected to increase the number of known small bodies by more than a factor of 10.
Gonggong is the fan favorite name for this icy distant world, but the International Astronomical Union's (IAU) Committee for Small-Body Nomenclature has the final say.
It’s time to give 2007 OR10 a name. We’re asking for your help to pick a suitable name for the largest as-yet-unnamed solar system world to submit to the International Astronomical Union (IAU).
A crescent view of MU69 reveals its bizarre shape. Let's look at lots of other fun-shaped space crescents.
New Horizons is back in action after going quiet for a period of solar conjunction following the 1 January flyby of 2014 MU69 (informally nicknamed
The latest images downlinked from New Horizons show MU69 to be a textbook example of a contact binary. How do contact binaries form? Updated with images released on 3 January.

Unaffected by the shutdown of the U.S. government, New Horizons is still on course for its New Year’s encounter with 2014 MU69 (nicknamed “Ultima Thule”). This post collects the latest images from New Horizons' approach to the tiny Kuiper belt object and will be updated regularly.
New Horizons is rapidly approaching its New Year’s encounter with the most distant world ever visited, 2014 MU69. Closest approach will be at a distance of 3,500 kilometers at about 05:33 on 1 January UTC.
A collection of before and after slider images showing how views of planets in our solar system have changed over the years since NASA was created.
On Jan. 1, NASA's New Horizons will perform a high-risk, high-reward flyby of an ancient world on the outskirts of the solar system.
Both OSIRIS-REx and New Horizons achieved first light on their still-distant targets this week. Between now and the end of 2018, Bennu and 2014 MU69 will turn from points of light into places.
The Planetary Society has always enjoyed the connections between science and art, so when I saw Leila Qışın's sketches pop up on her Twitter feed during the recent New Horizons team meeting, I knew I had to share them with you.
In a new preprint, Mike Brown and Bryan Butler show evidence that two Kuiper belt moons are even bigger than we used to think. They are Eris' moon Dysnomia, and Orcus' moon Vanth.
Throughout 2018, New Horizons will cruise toward its January 1 encounter with 2014 MU69. Preparations for the flyby are nearly complete.
Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
Haumea has a ring! Two telescopes used in the discovery—one in Slovenia, and one in Italy—received funding from The Planetary Society's Shoemaker Near Earth Object (NEO) Grant program, which helps amateur astronomers find, track and characterize near-Earth asteroids.
