New research presented at the Goldschmidt geochemistry conference suggests a significantly higher likelihood of finding Earth-like exoplanets with liquid water, essential for life, than previously…
A multi-institution team found evidence that the Earth’s magnetic field was stable 3.9 to 3.4 billion years ago when life is thought to have emerged,…
Researchers from Freie Universität Berlin have discovered phosphorus in the subsurface ocean of Saturn’s moon Enceladus. The search for extraterrestrial life in our solar system…
A study from the University of Rochester, using zircon crystals, found that plate tectonics was inactive during the period when life first appeared on Earth….
This molecule, never before seen in space, is believed to be a cornerstone of interstellar organic chemistry. Carbon compounds form the foundations of all known…
Saturn’s moon Enceladus contains phosphates, a key building block of life, at levels significantly higher than Earth’s oceans, suggesting potential habitability, according to a study…
Phosphorus, a key chemical element for many biological processes, has been found in icy grains emitted by the small moon and is likely abundant in…
Southwest Research Institute helped find evidence for phosphorus in the liquid water ocean beneath the moon’s icy surface. Researchers, using data from NASA’s Cassini mission,…
Professor Tomonori Totani from the University of Tokyo posits that cosmic dust, particularly grains measuring about 1 micrometer, could carry signs of extraterrestrial life to…
A new study posits that the earliest building blocks of life on Earth, namely amino acids and carboxylic acids, may have been formed due to…
Is there life on Mars? There’s lots of pieces of evidence that say there was once a huge ocean on Mars and an atmosphere that…
A study led by the researcher Susana Iglesias of the Instituto de Astrofísica de Canarias has detected the presence of large quantities of complex organic…
Radio emissions originating about 12 light-years outside our solar system reveal possible magnetic interactions between star YZ Ceti and its prospective close-orbiting, rocky planet. Researchers…
Gas giants orbiting our sun show a clear pattern; the more massive the planet, the lower the percentage of “heavy” elements (anything other than hydrogen…
Wouldn’t discovering life on other worlds be made easier if we knew the exact locations to search? However, opportunities to collect samples or access remote…
A new NASA mission to Saturn’s largest moon, Titan, is due to launch in 2027. When it arrives on the giant moon in the mid-2030s,…
These in-between regions could be prime sites for liquid water. In a new study, University of California, Irvine (UCI) astronomers describe how extraterrestrial life has…
