A brown dwarf in the southern constellation Columba is rocking back and forth on a steady rhythm, and the best explanation is a body at least as heavy as Jupiter circling it. If the signal holds up, that companion is…
The same observations carry a second result. The atmosphere has largely recovered from the Great Dimming, the episode in which Betelgeuse faded to its faintest in more than a century of records. Gas that had turned unusually cool just before…
Comets carry one of the raw ingredients that origin-of-life chemists prize most, hydrogen cyanide, and they carry plenty of it. New simulations of the young Earth’s bombardment find that comets almost never landed it on the surface in a usable…
The largest canyon in the solar system is not a dead landscape. A marsquake recorded by NASA’s InSight lander came from a fault slipping deep beneath Valles Marineris, the canyon system that slashes across Mars for nearly four thousand kilometres,…
NASA's Perseverance rover has collected samples from Mars, particularly from a region known as Sapphire Canyon near Jezero Crater. These samples may contain crucial evidence of ancient microbial life, making them significant for the search for extraterrestrial life. The samples…
Division of Planetary Science (DPS) carries out a survey of the Planetary Science Workforce to learn about the demographics, educational background and employment experience of the planetary science... Every five years or so, the American Astronomical Society (AAS) Division of…
An international team led by astronomers from the University of Trieste and the University of Warwick has discovered a double ring of planetary debris around a dead star. The discovery may foreshadow what happens to our own Solar System. The…
Using a technique developed by researchers at Brown, scientists have discovered a strange warm spot deep in the interior of the Red Planet. PROVIDENCE, R.I. [Brown University] - The satellites that orbit the Moon and Mars have provided scientists with a wealth…
Scientists use infrared telescopes like the US$10 billion James Webb to hunt for alien life. Infrared light easily penetrates thick cosmic dust and reveals clear chemical signatures of biological gases like methane and carbon dioxide hiding in distant exoplanet atmospheres.
