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...

While the massive atmosphere of Jupiter consists mainly of hydrogen and helium, the key to understanding the gas giant’s formation and evolution lies...

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...

Saturn is unique among planets observed to date in that some of its aurorae are generated by swirling winds within its atmosphere, and not just from the...

A team of professional astronomers and citizen scientists has discovered a giant exoplanet orbiting the G5-type star TOI-2180. An artist’s impression...

The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....

Solar system’s gas giants, such as Jupiter, Saturn, and massive exoplanets, were formed via the gas accretion onto the solid cores, each with a mass...

Astronomers have obtained 12 new high-precision transit observations of WASP-103b — a planet almost twice the size of Jupiter with 1.5 times its...

In their hunt for elusive exomoon candidates, astronomers have looked at 70 cool gas giants found by NASA’s Kepler space telescope. They’ve found only...

Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based facilities, astronomers have discovered a long-period sub-Neptune...

A team of professional astronomers and citizen scientists from the Backyard Worlds: Planet 9 project has discovered a planetary-mass object co-moving with...

Named b Centauri (AB)b (or b Centauri b), the newfound exoplanet is estimated to be only 15 million years old and 10 times the mass of Jupiter, according...

With an extremely short orbital period of 0.67 days (16 hours), the newly-discovered ultrahot Jupiter — named TOI-2109b — has the shortest...

Using photometric data from NASA’s Kepler/K2 mission, astronomers have identified 747 unique planet candidates and 57 multiplanet systems; of these candidates,...

Using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton satellite, astronomers have investigated unusual X-ray activity in three white dwarfs:...

Hubble’s snapshots of the outer Solar System’s planets — Jupiter, Saturn, Uranus, and Neptune — reveal both extreme and subtle changes...

Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and confirmed a...

Juno launched on August 5, 2011 and successfully entered Jupiter’s orbit on July 4, 2016. During each of the spacecraft’s 37 passes of Jupiter to date,...

Using the Immersion GRating INfrared Spectrometer (IGRINS) at the Gemini South Observatory on Cerro Pachon, Chile, astronomers have measured carbon-to-hydrogen...
