Astronomers discover a Jupiter‑sized planet orbiting a brown dwarf in CD‑35 2722, revealing a rare three‑body system of star, brown dwarf and planet. At a distance of roughly 73 light‑years in the constellation Columba, the star CD‑35 2722—about half...

in 1992 altered the object’s path, pulling it from a more remote trans-Saturnian trajectory into a warmer orbit closer to Jupiter. This “a-jump” in its orbital semimajor axis exposed the body to heightened solar energy, a phenomenon linked to the...

to form giant-planet cores before their surrounding gas disks disappear. For decades, the formation of gas giants like Jupiter and Saturn has challenged planetary scientists. The conventional model of core accretion requires a massive solid core to form...

system converged, with ice acting as a binding agent for fine dust particles. The researchers argue that the gas giant Jupiter played a decisive, formative role in this process. As Jupiter grew rapidly within the first million years of the solar...

and dust as its orbital path carries it closer to the Sun. Centaurs, which typically reside in the volatile region between Jupiter and Neptune, are believed to be migrants from the Kuiper Belt beyond Pluto. Because their orbits intersect with those of...

a class of clay that forms only when liquid water interacts with rock. Such minerals have never been detected beyond Jupiter, making their presence on Neptune’s tiny moons particularly striking. “If Neptune once had a system of moons that looked...

Mid-Infrared Instrument (MIRI), the team observed how gas—the fundamental building block for massive planets like Jupiter and Saturn—is depleted from these stellar nurseries over time. The Evolution of Disk Outflows The survey indicates that the...

Webb has discovered record-breaking brown dwarfs just twice the mass of Jupiter, challenging existing theories on how stars and planetary bodies form. The James Webb Space Telescope has pushed the boundaries of stellar formation theory, identifying a...

A new study published in The Astrophysical Journal Letters indicates that the orbital stability of the outer planets—Jupiter, Saturn, Uranus, and Neptune—could collapse just one billion years after the Sun completes its final transition into a white...

Astronomers utilizing the James Webb Space Telescope (JWST) have unveiled a striking atmospheric asymmetry on the hot Jupiter exoplanet WASP-17b, located roughly 1,300 light-years from Earth. By applying a sophisticated analysis technique known as...

NASA’s analysis of samples from asteroid Bennu reveals a surprising origin story linked to Jupiter’s early movements and the formation of our solar system. New analysis of extraterrestrial material returned by NASA’s OSIRIS-REx mission has provided a...

is the population of planets farther from their stars, including planets that orbit at distances more like Earth, Mars, or Jupiter do, and planets that might be cold, dim, or even free floating. Another gap is the need for large, uniform surveys that...

dramatic that effect can be. The comet is called 41P/Tuttle–Giacobini–Kresak, or simply 41P. It belongs to a group known as Jupiter family comets, short-period comets whose paths are shaped by the giant planet Jupiter. What happened to 41P was unusual....
