We’re always learning more about the worlds of the outer Solar System, and even those beyond.
Meet the Solar System’s five official dwarf planets, celebrate two major launches, and find out why planets sometimes seem to go backwards across the sky.
With space missions like JWST and Voyager, decades of development yield decades of discovery.
A crescent view of MU69 reveals its bizarre shape. Let's look at lots of other fun-shaped space crescents.
Look up at space at night from a dark location and you can see innumerable stars. Why, then, do photos of so many things in space show black space, devoid of stars?
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.
New Horizons has
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.
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.
Take a look at how electronics of spacecraft are built to survive the harshness of space environments.
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.
Throughout 2018, New Horizons will cruise toward its January 1 encounter with 2014 MU69. Preparations for the flyby are nearly complete.
The team reported two weeks ago that the first attempts at observing 2014 MU69 were unsuccessful. But in their third try, on July 17, astronomers in Argentina saw the telltale sign of MU69's presence: a stellar wink.
A team of scientists recently traveled to rural Argentina in the hopes of catching New Horizons' next target—Kuiper Belt object MU 69—crossing in front of a distant star.
Using new image processing techniques, Alex Parker brings new life to an old image of Jupiter captured by the New Horizons mission on its way to Pluto over a decade ago.
In the second and final chapter of our series, we’ll explore what the rocket equation has to say about travel through the solar system, using the example of launching a rocket to Pluto.
What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.
