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...
TRAPPIST-1, an ultracool dwarf star located 38.8 light-years away in the constellation of Aquarius, hosts seven planets. The period ratios of neighboring...
In a new paper published in the Astrophysical Journal, Dr. Ravi Kopparapu of NASA’s Goddard Space Flight Center and colleagues assessed the potential...
Astronomers using Webb’s MIRI (Mid-Infrared Instrument) have imaged Epsilon Indi Ab, a gas giant several times the mass of Jupiter located around 12...
Established in 2006 by the International Astronomical Union, the current definition specifies that to qualify as a planet, a celestial body must orbit...
Astronomers have discovered an exoplanet five times the mass of Jupiter that makes a very peculiar orbit around its star.
An artist’s impression of TIC...
