lithium, the lightweight metal that powers electric‑vehicle batteries and large‑scale storage systems. In September 2025, Neptune Energy disclosed that independent assessors had verified a resource of 43 million tonnes of lithium‑carbonate‑equivalent at...

at an unseen giant planet sculpting its whole system, offering fresh clues for astronomers. Astronomers have identified a Neptune‑sized world that circles its star in the opposite direction of the star’s rotation, a configuration that challenges...

Webb data hint Neptune’s tiniest moons could be relics of an ancient satellite system shattered by a violent cosmic event billions of years ago. New observations from the James Webb Space Telescope indicate that the tiny inner moons of Neptune may be...

Astronomers have discovered hidden clues in the faint light of Neptune’s moons that may explain why its satellite system is unlike any other in the solar system. New evidence from the James Webb Space Telescope (JWST) indicates that the rings and minor...

New observations of a distant object beyond Neptune reveal an unexpected atmosphere, reshaping theories on which worlds can hold one. A distant, icy body orbiting past Neptune has revealed an unexpected gaseous envelope, a finding that challenges...

with a significant display on September 26, as the Harvest Moon rises in tandem with Saturn and the distant planet Neptune. While Saturn will be easily visible to the naked eye, Neptune—shining at approximately magnitude 8—will remain a challenge,...

Telescope on Mauna Kea, GJ 3378b was initially assigned a mass of 5.26 Earth masses, classifying it as a mini‑Neptune‑type world dominated by gases. A follow‑up campaign by the UC Irvine team employed the Habitable‑zone Planet Finder on the Hobby‑Eberly...

NASA’s Hubble and Webb telescopes have discovered that small, icy objects beyond Neptune may hold the key to understanding the early history of our planets. A collaborative investigation by the Hubble and James Webb Space Telescopes has uncovered a...

of the processes that transition a chaotic cloud of debris into a structured planetary system. Orbiting the Sun far beyond Neptune, “Trans-Neptunian Objects” are surviving relics from our solar system’s formation. Hubble and @NASAWebb studied the color,...

the James Webb Telescope might overlook hidden water on distant exoplanets, raising doubts about its detection limits. Mini‑Neptunes—planets a bit smaller than Neptune yet less dense than Earth—have long confounded astronomers because no analogue exists...

the team turned to archival data from the Voyager 1, Voyager 2 and New Horizons flybys of Jupiter, Saturn, Uranus and Neptune. By comparing theoretical emission models with the observed ultraviolet spectra, they derived upper limits on the strength of...

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 dwarf. This finding...

is designed to deliver population level insight, the kind you need to answer questions like: How common are Earth mass to Neptune mass planets beyond the “hot” close in region? How do planetary systems vary across the galaxy? How often do planets form...

month, around August 12, 2026, six planets will line up across the morning sky: Jupiter, Mercury, Mars, Uranus, Saturn, and Neptune Look before sunrise to catch the planet parade — and don’t stop there. The same… pic.twitter.com/T4JwNwQNMh — Star Walk...

Ongoing Exploration of Interstellar Space Having visited every giant planet, including the only close fly‑bys of Uranus and Neptune, Voyager 2 pressed onward after completing its primary objectives. The probe eventually breached the heliopause, the...

core fraction and potential temperature. Black open circles labeled “N” and “U” mark the core–mantle boundary conditions of Neptune and Uranus (Nettelmann et al., 2013). The orange shaded area corresponds to Saturn’s estimated core‑mantle conditions...

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 the solar...
