Caltech researchers discover a process that turns carbon dioxide into molecular oxygen.
A UC Riverside-led team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the smaller planets in other solar systems.
Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, including CNRS researchers, has found that one family of comets, the hyperactive comets, contains water similar to terrestrial water. The study relies in particular on measurements of comet 46P/Wirtanen carried out by SOFIA, NASA's Stratospheric Observatory for Infrared Astronomy.
Three extrasolar comets have been discovered around the star Beta Pictoris, 63 light years away, by the University of Innsbruck. Analysis of data from the current NASA mission TESS by Sebastian Zieba and Konstanze Zwintz from the Institute for Astro- and Particle Physics, together with colleagues from Leiden University (Netherlands) and the University of Warwick (UK) has revealed the objects for the first time using TESS data.
Scientists at Oak Ridge National Laboratory studying super-cold states of water discovered a pathway to the unexpected formation of dense, crystalline phases of ice thought to exist beyond Earth's limits. Their findings, reported in Nature, challenge accepted theories and could lead to better understanding of ice found on other planets, moons and elsewhere in space.
The stark difference between the moon's heavily-cratered farside and the lower-lying open basins of the Earth-facing nearside has puzzled scientists for decades. Now, new evidence about the moon's crust suggests the differences were caused by a wayward dwarf planet colliding with the moon in the early history of the solar system.
A years-long study that involved scientists and experiments at Berkeley Lab and UC Berkeley concludes that an odd assortment of particles found in beach sands in Japan are most likely fallout debris from the 1945 Hiroshima A-bomb blast.
Astronomers map the substance aluminum monoxide (AlO) in a cloud around a distant young star -- Origin Source I. The finding clarifies some important details about how our solar system, and ultimately we, came to be. The cloud's limited distribution suggests AlO gas rapidly condenses to solid grains, which hints at what an early stage of our solar evolution looked like.
Which of Earth's features were essential for the origin and sustenance of life? And how do scientists identify those features on other worlds? A team of investigators with array of expertise ranging from geochemistry to planetary science to astronomy published this week an essay in Science urging the research community to recognize the vital importance of a planet's interior dynamics in creating an environment that's hospitable for life.
Observers watching January's total eclipse of the Moon saw a rare event, a short-lived flash as a meteorite hit the lunar surface. Spanish astronomers now think the space rock collided with the moon at 61,000 kilometers an hour, excavating a crater 10 to 15 meters across. Professor Jose Maria Madiedo of the University of Huelva, and Dr. Jose L. Ortiz of the Institute of Astrophysics of Andalusia, publish their results in a new paper in Monthly Notices of the Royal Astronomical Society.
