JWST reveals water-ice clouds on a cold Jupiter-mass world
Apr 23, 2026 (SPX)
Epsilon Indi Ab orbits the star Epsilon Indi A in the southern constellation Indus. The planet has a mass of 7.6 Jupiter masses but a similar diameter to Jupite...
Plato clears major vacuum and thermal trials ahead of 2027 launch
Apr 23, 2026 (SPX)
Plato recently came out of the Large Space Simulator at ESA's Test Centre, where engineers exposed the spacecraft to the vacuum and temperature extremes it will...
Tectonic cycling may return buried seafloor microbes to life
Apr 17, 2026 (SPX)
These microbes can remain dormant for thousands or even millions of years beneath about a kilometer of ocean sediment. They survive with specialized adaptations...
Three-Body Exoplanet System TOI-201 Caught Changing Its Orbital Architecture in Real Time
Apr 16, 2026 (SPX)

Desert Worlds in Habitable Zones Unlikely to Support Life Without Sufficient Surface Water
Apr 16, 2026 (SPX)
More than 6,000 exoplanets have been confirmed, but only some are candidates for life. The search has focused on planets in the habitable zone, a range of dista...
Webb finds metal-poor atmosphere on giant world around red dwarf
Apr 04, 2026 (SPX)
TOI-5205 b is similar in size to Jupiter but orbits a cool red dwarf star that is only about four times Jupiter's size and roughly 40 percent the mass of the Su...
Tough microbe study backs idea of life moving between planets
Mar 29, 2026 (SPX)
The study, published in PNAS Nexus, focused on Deinococcus radiodurans, a desert bacterium from the high deserts of Chile known for surviving extreme cold, dryn...
Stellar space weather may blur alien radio beacons
Mar 29, 2026 (SPX)
For decades, many SETI searches have optimized their detection pipelines for extremely sharp, spike like features in radio spectra that are unlikely to be cause...
Study questions assumptions about hidden alien technosignals
Feb 27, 2026 (SPX)
Despite decades of monitoring across radio, optical, and infrared bands, no technosignature has been confirmed, a result often attributed to the fact that only ...
Study revisits chances of detecting alien technosignatures
Feb 18, 2026 (SPX)
Despite these efforts, no technosignature has been confirmed so far, a silence often attributed to the fact that only a tiny fraction of the cosmic search space...
Cheops spots inside out exoplanet quartet
Feb 16, 2026 (SPX)
Astronomers have now found a nearby planetary system that breaks that familiar pattern. An international team led by Thomas Wilson of the University of Warwick ...
Hydrogen sulfide detected in distant gas giant exoplanets for the first time
Feb 16, 2026 (SPX)
Gas giants, such as Jupiter and Saturn in our own solar system, are large planets made mostly of helium and/or hydrogen around a dense core, but they have a bit...
Debris disc oddities point to hidden outer planets
Feb 13, 2026 (SPX)
The study used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to image 24 debris discs made of dust, gas and rocks orbiting stars in systems b...
JWST study links sulfur rich gas giants to core growth in distant HR 8799 system
Feb 10, 2026 (SPX)
HR 8799 lies about 133 light years away in the constellation Pegasus and hosts four giant planets, each between five and ten times the mass of Jupiter and orbit...
Pressure driven leakage from marine snow feeds deep ocean microbes
Feb 10, 2026 (SPX)
The study, led by biologists at the Department of Biology and research centers Nordcee and the Danish Center for Hadal Research, focuses on so called marine sno...
Einstein effect clears planets from tight double star systems
Feb 06, 2026 (SPX)
Of the more than 6,000 extrasolar planets, or exoplanets, confirmed to date - most of them found by NASA's Kepler Space Telescope and the Transiting Exoplanet S...
Engineered microbes use light to build new molecules
Feb 06, 2026 (SPX)
