Astronomers Measure Temperature Shift in Brown Dwarfs for the First Time
Brown dwarfs, the larger cousins of giant planets, undergo atmospheric changes from cloudy to cloudless as they age and cool. A team of astronomers led…
Water on the Moon Raises Questions About Its Origin Story
It’s amazing what a difference a little water can make. The Moon formed between about 4.4 and 4.5 billion years ago when an object collided…
New ALMA Discovery Raises Questions About the Habitability of Proxima b
Space weather emitted by Proxima Centauri, the star closest to our sun, may make that system rather inhospitable to life after all. Using data from…
Astronomers Unlock the Mysteries of Super-Earths
A star about 100 light-years away in the Pisces constellation, GJ 9827, hosts what may be one of the most massive and dense super-Earth planets…
Carbon-Rich Stardust Grains Unlock Astrophysical Mysteries
Dust is everywhere — not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance…
Oxygen-Rich Iron Reservoirs Could Have Played a Crucial Role in the Creation of Life
A new study from the Carnegie Institution For Science shows that reservoirs of oxygen-rich iron between the Earth’s core and mantle could have played a…
