New high-resolution images of the Fomalhaut A system from the NASA/ESA/CSA James Webb Space Telescope show three debris belts extending out to 23 billion...
Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research,...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Terbium, a chemical element with the symbol Tb and atomic number 65, has never before been seen in an exoplanet atmosphere.
This illustration shows how...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
Since its launch in April 2018, NASA’s Transiting Exoplanet Survey Satellite (TESS) have mapped more than 93% of the entire sky, discovered 329 new alien...
Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
Observing magnetic star-planet interactions offers promise for determining the magnetic fields of exoplanets. Models of star-planet interactions predict...
The dayside of TRAPPIST-1b, the innermost planet in the seven-planet system TRAPPIST-1, has a temperature of about 227 degrees Celsius (441 degrees Fahrenheit),...
To facilitate studies of exo-Venus candidates, astronomers from the University of California, Riverside, the University of California, Santa Cruz, Brown...
Gas giants, like other planets, form from protoplanetary disks of material around protostars. According to core accretion theory, they first form a core...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
Dr. Lokesh Mishra and his colleagues from the University of Bern and Geneva Observatory propose that the space of planetary system architectures be partitioned...
Wolf 1069b is the sixth closest Earth-mass exoplanet situated in the conservative habitable zone of its parent star, after Proxima Centauri b, Gliese 1061d,...
Astronomers recently announced the discovery of TOI-700e, a habitable-zone, Earth-sized planet some 102 light-years away in the southern constellation...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have validated the discovery of a warm, 0.99 Earth-radius exoplanet interior to the habitable...
The newly-discovered alien world, named TOI-700e, is 95% Earth’s size and likely rocky.
An artist’s impression of TOI-700e (larger planet) and TOI-700d....
