Microbes and minerals may have set off Earth’s oxygenation
Scientists propose a new mechanism by which oxygen may have first built up in the atmosphere
Richard Binzel: Eyes on the skies and a passion for planetary science
Over more than three decades at MIT, Binzel developed key insights into the solar system and played a role in multiple NASA missions.
A “hot Jupiter’s” dark side is revealed in detail for first time
The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream.
MIT engineers test an idea for a new hovering rover
A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.
Could acid-neutralizing life-forms make habitable pockets in Venus’ clouds?
A new study shows it’s theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions.
“Newer, nimbler, faster:” Venus probe will search for signs of life in clouds of sulfuric acid
Report led by MIT scientists details a suite of privately-funded missions to hunt for life on Earth's sibling planet.
TESS discovers a planet the size of Mars but with the makeup of Mercury
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
One year on this giant, blistering hot planet is just 16 hours long
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
Nanograins make for a seismic shift
A new study finds curious properties of tiny crystals hold clues to earthquake formation.
Astronomers detect signs of an atmosphere stripped from a planet during giant impact
Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.
Scientists find evidence the early solar system harbored a gap between its inner and outer regions
The cosmic boundary, perhaps caused by a young Jupiter or an emerging wind, likely shaped the composition of infant planets.
Rover images confirm Jezero crater is an ancient Martian lake
The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.
Zeroing in on the origins of Earth’s “single most important evolutionary innovation”
A new study shows oxygenic photosynthesis likely evolved between 3.4 and 2.9 billion years ago.
Taylor Perron receives 2021 MacArthur Fellowship
In his research, the geomorphologist seeks connections among landscape evolution, biodiversity, and human history.
TESS Science Conference II draws nearly 700 virtual attendees
Not just an exoplanet-finder anymore, TESS yields diverse astrophysics results at second science conference.
