Taking advantage of a total lunar eclipse in January 2019, astronomers using the NASA/ESA Hubble Space Telescope have measured the amount of ozone in the...
A team of researchers at the Massachusetts Institute of Technology (MIT) has demonstrated that single-celled microorganisms such as Escherichia coli and...
A team of astrobiologists from the Carl Sagan Institute at Cornell University has developed a spectral field guide for Earth-like exoplanets transiting...
Since exoplanets are so far away, astronomers cannot look for signs of extraterrestrial life by visiting these distant worlds. Instead, they must use a...
The Habitable Exoplanet Observatory (HabEx) would use a telescope with a mirror larger than Hubble’s, and would employ origami techniques to utilize...
A team of researchers at MIT has found that phosphine, which is among the stinkiest, most toxic gases on Earth, cannot be produced in any other way except...
Using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument aboard NASA’s Mars Reconnaissance Orbiter, researchers have...

K-type dwarf stars are dimmer than the Sun but brighter than the faintest stars. These stars live a very long time — 17 billion to 70 billion years,...
By looking at Earth’s natural history, Cornell University’s Carl Sagan Institute astrobiologists Jack O’Malley-James and Lisa Kaltenegger have found...
Jupiter’s moon Europa is one of the most compelling targets in the search for life beyond Earth. However, its water-ice surface is affected by the harsh...
A team of leading astronomers, biologists and geologists have come together under the Nexus for Exoplanet System Science (NExSS), a NASA research coordination...
