Parker Solar Probe pulls back the veil on Venus’s night side
When flying past Venus in July 2020, Parker Solar Probe’s WISPR instrument, short for Wide-field Imager for Parker Solar Probe, detected a bright rim around the edge of the planet that may be nightglow — light emitted by oxygen atoms high in the atmosphere that recombine into molecules in the nightside. The prominent dark feature…

Five years after New Horizons flyby, scientists assess next mission to Pluto
A composite of enhanced color images of Pluto (lower right) and Charon (upper left), taken by NASA’s New Horizons spacecraft as it passed through the Pluto system on July 14, 2015. This image highlights the striking differences between Pluto and Charon. The color and brightness of both Pluto and Charon have been processed identically to…

Discoveries at solar system’s distant frontier shed light on how planets form
The uniform color and composition of Arrokoth’s surface shows the Kuiper Belt object formed from a small, uniform, cloud of material in the solar nebula, rather than a mishmash of matter from more separated parts of the nebula. The former supports the idea that Arrokoth formed in a local collapse of a cloud in the…

New Horizons finds Ultima Thule has an unexpected, flattened shape
Scientists’ understanding of the shape of Ultima Thule, officially known as 2014 MU69, has changed since the New Horizons spacecraft’s Jan. 1 flyby. Imagery downlinked by the probe in recent weeks suggests Ultima Thule’s two lobes have a flatter shape than the spherical projection suggested by the flyby’s initial pictures. The dashed blue line marks…

Ultima Thule revealed in new detail with fresh flyby image
A new image captured minutes before NASA’s New Horizons probe zipped by a rocky object in the Kuiper Belt on New Year’s Day shows the dual-lobed world — nicknamed Ultima Thule — is covered with intriguing fractures and a large crater-like depression that could provide clues about the early history of the solar system. The…

Most distant object ever visited resembles a snowman
The Kuiper Belt Object 2014 MU69 — nicknamed “Ultima Thule” — appears as a dual-lobe contact binary in this photo captured by NASA’s New Horizons spacecraft at a distance of around 18,000 miles (28,000 kilometers). Credit: NASA/SWRI/JHUAPL LAUREL, Maryland — The first well-resolved image of the faraway chunk of rock fleetingly visited by NASA’s New…
