The field of SETI searches for technosignatures could provide the first detection of life beyond Earth through the technology that an extraterrestrial...
Astronomers using the Immersion GRating INfrared Spectrograph (IGRINS) instrument on the Gemini South telescope have examined the atmosphere of WASP-121b,...
One of these exoplanets, HD 20794d, is likely to be a rocky planet in the habitable zone of its parent star, the G-dwarf HD 20794.
This image shows the...
WASP-132 is a unique multi-planet system in that both an inner rocky planet and the newly-discovered outer giant planet are in a system with a hot-Jupiter...
In a new paper, planetary researchers from Texas A&M University and the University of Washington introduce a new thermodynamic concept called the centotectic...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
Kepler-51 is a 500-million-year-old G-type star hosting four low density planets, according to a new paper published in the Astronomical Journal.
This...
The newly-discovered exoplanet orbits TOI-3261 (also known as TIC 358070912), an inactive main-sequence star located 300 parsecs (978.5 light-years) away...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured high-resolution images of eight protoplanetary disks in Sigma...
A team of scientists from the Lunar and Planetary Laboratory at the University of Arizona, TU Delft, and Caltech has developed a new method to compute...
There is no obvious evidence for one or more large exoplanets plowing through the face-on debris disk encircling Vega, one of the brightest stars in the...
The TRAPPIST-1 system is a compact system of at least seven exoplanets with sizes similar to Earth. Penn State and SETI Institute astronomers spent 28...
In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope to the more-distant view from NASA’s New...
An exoplanet at least half the mass of Venus orbits Barnard’s star, the closest single star to the Sun, once every 3.15 days.
An artist’s impression...
Astronomers using the Keck II 10-m telescope have discovered evidence for an Earth-mass planet and a brown dwarf orbiting a white dwarf star. The planet...
There is a significant difference between the two edges of the atmosphere of WASP-107b, a super-Neptune exoplanet about the size of Jupiter but only a...
Using the Near-Infrared Imager and Slitless Spectrograph (NIRISS) instrument on the NASA/ESA/CSA James Webb Space Telescope, astronomers have discovered...
Water is an important component of exoplanets, with its distribution, that is, whether at the surface or deep inside, fundamentally influencing the planetary...
