Astronomers using the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope have captured coronagraphic images of the HR 8799...
For a century, astronomers have been studying Barnard’s star in the hope of finding planets around it. First discovered by E.E. Barnard at Yerkes Observatory...
Astronomers may finally have settled the question of what is causing highly energetic X-rays from WD 2226-210, a white dwarf star located at the center...
Ultrahot Jupiters, an extreme class of planets not found in our Solar System, provide a unique window into atmospheric processes. Using four telescope...
White dwarfs may present amenable environments for life on planets formed within or migrated to their habitable zones, generating warmer surface environments...
The candidate planetary system, detected with the microlensing method, is thought to move at least 540 km per second (1.2 million mph).
An artist’s impression...
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...
