Uranus and Neptune May Be More Rock Than Ice, New Research Suggests
A new pre-print study proposes that Uranus and Neptune might not be “ice giants” after all. Using assumption-free models, scientists found their interiors could range from mostly icy to mostly rocky, suggesting we know far less about these distant worlds and that new missions are essential to solve the mystery.

Hubble Spots White Dwarf Devouring Icy Pluto-Like Planet 260 Light-Years Away
Using Hubble’s ultraviolet spectrograph, scientists detected carbon, nitrogen, sulphur, and abundant oxygen falling onto a white dwarf 260 light-years away, evidence of an icy planetesimal being torn apart. The find shows volatile worlds can persist into a star’s final stages, offering a preview of the Sun’s distant fate.

Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

NASA Confirms Discovery of 6,000 Exoplanets Beyond Our Solar System
NASA has confirmed 6,000 exoplanets beyond our solar system, highlighting three decades of accelerating discovery. From scorching hot Jupiters to worlds with jewel-like clouds, the catalog reflects cosmic diversity. Future missions aim to identify true Earth analogs and investigate signs of life across distant planetary systems.

Exoplanets Explained: How Astronomers Find Worlds Orbiting Stars Beyond the Sun
Exoplanets are planets orbiting stars outside our solar system, hidden by stellar glare and detected indirectly. Astronomers identify them by tracking star wobbles or dips in brightness during planetary transits. NASA’s Kepler mission revealed thousands, with TESS now expanding the search. These discoveries confirm that planetary systems are abun...

Mysterious Planet Nine May Still Lurk in the Outer Solar System
Astronomers have long speculated about a hidden planet—Planet Nine—lurking beyond Neptune. First proposed in 2016, the theory explains the strange orbits of distant Kuiper Belt objects through the gravitational pull of a massive, unseen world. Caltech researchers remain confident, while others suggest alternatives like debris rings or even a bl...

Hubble Captures First Images of Ancient Interstellar Visitor Comet 3I/ATLAS
Hubble has captured images of comet 3I/ATLAS, an ancient interstellar object likely 7 billion years old. As only the third known visitor from beyond the solar system, it offers rare insights into distant planetary systems. With its water ice and D-type asteroid-like dust, 3I/ATLAS is now under global scientific scrutiny before it vanishes back into...

China’s Tianwen 2 Probe Snaps Striking Views of Earth and Moon While En Route to Asteroid
China’s Tianwen 2 spacecraft, now millions of kilometers from Earth, captured distant images of Earth and the moon as it journeys to asteroid Kamo'oalewa. Set to collect samples by 2026 and return them in 2027, the mission could reveal insights into the solar system’s formation—before continuing on to a second deep-space target, comet 311P/PA...

New Interstellar Object 3I/ATLAS Could Reveal Secrets of Distant Worlds
Astronomers have confirmed the arrival of 3I/ATLAS, only the third interstellar object ever spotted in our solar system. First seen on July 1, 2025, by the ATLAS survey team in Chile, it was quickly identified by its unusual hyperbolic orbit and comet-like tail. Larger and brighter than either 1I/ʻOumuamua or 2I/Borisov, 3I/ATLAS is estimated to b...

NASA's New Horizons Proves Deep-Space Navigation via Stellar Parallax
NASA’s New Horizons spacecraft accomplished a world-first by performing a deep-space stellar navigation test using stellar parallax. On April 23, 2020, while 438 million miles from Earth, it imaged nearby stars Proxima Centauri and Wolf 359. From the spacecraft’s distant viewpoint, the stars appeared slightly shifted compared to Earth-based obs...

Scientists Spotted the Largest Comet Lying in the Solar System’s Outskirts with Outbursting Gases
NASA confirms comet C/2014 UN271, the largest known from the Oort Cloud, is chemically active. Detected by ALMA from far beyond Neptune, the comet’s carbon monoxide jets offer rare insights into icy body chemistry and early solar system conditions.

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...

Scientists Reportedly Found a Potential Sign of Life on a Distant Planet: What You Need to Know
The expert team of scientists from the University of Cambridge, UK, has made a shocking statement by claiming that there are signs of life at a distant planet, K2- 18 b. The scientists have discovered DMS and DMDS molecules in the plant’s atmosphere. However, the claims are being questioned worldwide.

Most Promising "Hints" Of Potential Life Detected On Distant Planet
Astronomers announced Thursday that they had detected the most promising "hints" of potential life on a planet beyond our solar system, though other scientists expressed skepticism.

NASA Supercomputer Finds Spiral Structure in the Oort Cloud’s Inner Region
A NASA supercomputer model suggests that the Oort Cloud’s inner structure forms a spiral, influenced by galactic tides. The Oort Cloud, a distant icy shell surrounding the solar system, has remained unobservable due to its vast distance. Researchers believe this finding could redefine understanding of how comets originate and interact with cosmic...
