Lava Lakes on Io Images in Infrared

I don’t think there is an astronomer who doesn’t love a pretty high resolution image of …well… pretty much anything in space. Give me a crisp clear galaxy, or a nebula, or even a quiet frost field on another planet and I will happily stare at the pretty picture. But science… the coolest science sometimes comes from the gnarliest looking images.   Back in May and October 2023, the Juno spacecraft flew near Jupiter’s volcanic moon Io and pointed its infrared camera and Io to see what it could see… and what it saw was lava lakes that appear hottest around the edges.  The data isn’t pretty,...

The Dying Sun will Take Out the Earth

The Dying Sun will Take Out the Earth

Clumps of debris from a disrupted planetesimal are irregularly spaced on a long and eccentric orbit around the white dwarf. Individual clouds of rubble intermittently pass in front of the white dwarf, blocking some of its light. Because of the various sizes of the...

Watching Atoms Escape Venus

This image was processed from archived Mariner 10 data by JPL engineer Kevin M. Gill. Credit: NASA/JPL-Caltech Atmospheres are what make a planet good or evil for life. One of the questions I get asked most often is, “Can we terraform Venus to be like Earth?” Sure!...

Catch the (Alien) Rainbow

Each glory is unique, depending on the composition of the planet’s atmosphere and the colors of the light from the star that illuminates it. WASP-76 (the «Sun» of WASP-76b) is a yellow and white main sequence star like our Sun, but different stars create glories with...

Can Radar Protect Us From the Earth-Killer?

Deep Space Station 13 at NASA’s Goldstone complex in California – part of the agency’s Deep Space Network – is an experimental antenna that has been retrofitted with an optical terminal. In a first, this proof of concept received both radio frequency and laser signals...

Using Radar to Watch Asteroid Rotation

The day before asteroid 2008 OS7 made its close approach with Earth on Feb. 2, this series of images was captured by the powerful 230-foot (70-meter) Goldstone Solar System Radar antenna near Barstow, California. Credit: NASA/JPL-Caltech One of the most...

Migration Solves Exoplanet Puzzle

Artistic representation of an exoplanet whose water ice on the surface is increasingly vaporizing and forming an atmosphere during its approach to the central star of the planetary system. This process increases the measured planetary radius compared to the value the...

Water on Asteroids

Using data from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), Southwest Research Institute scientists have discovered, for the first time, water molecules on the surface of an asteroid. Scientists looked at four silicate-rich asteroids using the...
