Change'e 5 landing site overview. Credit: Chinese National Space Agency's (CNSA) Lunar Exploration and Space Engineering Center On Dec 1, 2020, China landed the Chang’e 5 mission on the near side of the moon. Three days later, that little lander lifted back off with about 1.7 kg lunar rocks and soil. On Dec 16 this mission would successfully return to Earth and analysis would begin. In this sample, researchers found tiny glass beads produced in Lunar Volcanoes. Analysis of their chemical composition indicates these beads were formed as recently as 120 million years ago. It is unclear...
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...
It’s a Star-Eat-Planet Universe Out There
Artist's impression of a terrestrial planet being captured by a twin star. Credit: intouchable, OPENVERSE Data, at the end of the day, is our first and last source of understanding. We look, build models to match what we see, predict things we haven’t seen yet, and...
Closer Look: Diversity Makes Understanding More Difficult (Planetary Edition)
Planet-forming discs around young stars and their location within the gas-rich cloud of Orion, roughly 1600 light-years from Earth. The mesmerising images of the discs were captured using the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument...
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...
Bennu Descended from an Ocean World
A view of the outside of the OSIRIS-REx sample collector. Sample material from asteroid Bennu can be seen on the middle right. Scientists have found evidence of both carbon and water in initial analysis of this material. The bulk of the sample is located inside....
Mimas’ Baby Ocean
In this view captured by NASA's Cassini spacecraft on its closest-ever flyby of Saturn's moon Mimas, large Herschel Crater dominates Mimas, making the moon look like the Death Star in the movie "Star Wars." Herschel Crater is 130 kilometers, or 80 miles, wide and...
