How to participate in a Wave to OSIRIS-REx social media campaign. Plus, how to see the craft in the sky and where to submit your images.

Exoplanet WASP-12b has the unique capability to trap 94 percent of the visible starlight falling into its atmosphere. The result is a world as black as fresh asphalt.

Researchers using Venus Express spacecraft data report “stationary waves” and slowly moving features in the planet’s upper clouds, during Venus’ long and mysterious night.

The Cassini spacecraft has become part of Saturn, the planet it studied so spectacularly and so long. Cassini’s last images and final moments, here.

NASA said Cassini’s final flyby of Titan – Saturn’s large moon – went as planned. The spacecraft is now on a course that’ll take it inside Saturn’s atmosphere, for a fiery end to its mission, on September 15.

And last week mission scientists filed a flight plan for New Horizons’ next flyby – of the Kuiper Belt object 2014 MU69 – in early 2019. It’ll be farthest encounter yet between an earthly spacecraft and distant solar system body.

Milestones for Cassini’s final week at Saturn. Today’s distant flyby of the large moon Titan will slow down the spacecraft enough so that – on Friday – Cassini will make its final plunge into Saturn’s atmosphere.

Too little UV light, and life might not ever start. Too much, in the form dramatic UV flares from stars, and the atmospheres of orbiting planets might undergo damage.

The sun drives Earth’s auroras. But Jupiter’s brightest auroras may be accelerated by processes within the giant planet’s own magnetic field.

The 14 geological features are the first to be officially named, following the New Horizons spacecraft’s close flyby of Pluto in July 2015.
