The NASA/ESA/CSA James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding...
University of Toronto astronomer Evelyn Macdonald and her colleagues have identified substantial differences in surface temperature, sea ice and water...
The NASA/ESA/CSA James Webb Space Telescope mission today released its first full-color scientific images and spectroscopic data.

Pulsar planets are extrasolar worlds that are found orbiting pulsars, or rapidly rotating neutron stars. In new research, Iuliana Camelia Nitu, a Ph.D....
An international team of astronomers, using the radial velocity (RV) method, has discovered a third planet in the planetary system HD 33142.
An artist’s...
Astronomers using the Gemini Planet Imager instrument at the Gemini South telescope in Chile have imaged a sample of 44 bright Herbig Ae/Be and T-Tauri...
HD 53143 is a one-billion-year-old solar-type star located 59.8 light-years away in the constellation of Carina.
This composite image shows the HD 53143...
Using the radial velocity technique, astronomers have discovered a super-Earth exoplanet orbiting near the inner edge of the habitable zone of the cool...
In a new paper published in the International Journal of Astrobiology, Houston Community College researcher Irina Romanovskaya proposes that free-floating...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a transiting multi-planetary system around a nearby red dwarf (M-dwarf)...
In a new paper in the Astrophysical Journal, a duo of astronomers from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University...
For over 70 years, astronomers have been scanning for radio or optical signals from other civilizations in the search for extraterrestrial intelligence...
In a study published on April 25, 2022 in the Astrophysical Journal Supplement Series, astronomers analyzed archival spectroscopic and photometric data...
The gravity of a large object in space can keep a smaller object from spinning, a phenomenon called tidal locking. The discovery and characterization of...
It’s raining vaporized rock on WASP-178b, and KELT-20b has its upper atmosphere getting hotter rather than cooler because it is being sunburned by intense...
Using the Subaru Telescope and the NASA/ESA Hubble Space Telescope, astronomers have found evidence for a Jupiter-like protoplanet around the young star...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
The case for methane as a biosignature stems from its instability in the planet’s atmosphere. Because photochemical reactions destroy atmospheric methane,...
According to NASA astronomers, the 5,000-plus exoplanets confirmed so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter,...
Physicists have observed the transition from a previously known cubic phase, ice VII, to the newly-discovered intermediate, and tetragonal, phase, ice...
