In a study published recently in the Astrophysical Journal Letters, a team of astronomers analyzed spectroscopic atmospheric data from 19 exoplanets, ranging...
There isn’t a strong correlation between gas giant and host star compositions when it comes to elements heavier than hydrogen and helium, according to...
Astronomers using the Subaru Telescope in Hawaii have found 20 new moons orbiting Saturn. The discovery brings the total number of known Saturnian moons...
Astronomers have discovered a massive exoplanet orbiting Gliese 3512 (GJ 3512), an M-dwarf star (red dwarf) located 31 light-years away. Dubbed Gliese...
Saturn is so beautiful that astronomers cannot resist using the NASA/ESA Hubble Space Telescope to take yearly snapshots of the gas giant when it is at...
A volcanically active rocky exomoon may orbit WASP-49b, a hot gas giant approximately 550 light-years away in the constellation of Lepus.
An artist’s...
The temperature on the nightsides of short-period gas giants (hot Jupiters) is surprisingly uniform, suggesting the dark sides of these exoplanets have...
Using data from several ground-based telescopes, astronomers found that a nearby star called HR 5183 hosts a giant planet with an orbital period of between...
An international team of astronomers has managed to peer deep into the Jovian atmosphere using the Atacama Large Millimeter/submillimeter Array (ALMA)...
An energetic head-on collision between a large planetary embryo and the proto-Jupiter about 4.5 billion years ago could explain puzzling gravitational...
The NASA/ESA Hubble Space Telescope obtained a detailed image of Jupiter on June 27, 2019, when the gas giant was approximately 400 million miles (644...
WASP-121b is about two times bigger than Jupiter and 1.2 times more massive. Discovered in 2016, the planet is located 881 light-years away in the constellation...
