Portales, described the object as a massive gaseous body bound to an unusually heavy companion. She remarked: “In the Solar System we have a clear separation between planets and the Sun, making moon definitions straightforward. In CD‑35 2722, where the...

planets trace back to the same ancient interstellar ices. In essence, the story of water on Earth began long before the Solar System formed. The Bigger Picture: How Water Travels Through Space Chemical models have long predicted that deuterium...

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 moons of Neptune may be...

Scientists have discovered organic carbon in ancient Martian river rocks, providing a compelling new clue in the ongoing search for past life on the Red Planet. New data harvested from the Martian surface has unveiled the presence of organic carbon...

of new samples from asteroid Bennu reveals a surprising origin story that challenges our current understanding of the solar system’s history. Deep-Space Samples Rewrite the Origin Story of Asteroid Bennu New geochemical analysis of material retrieved...

Solar wind‑driven giant plasma waves are eroding Mars’ atmosphere, shedding new clues on the planet’s dramatic loss. New research published in Science Advances shows that the solar wind does far more than skim past Mars. The study identifies gigantic...

behavior of a natural icy body that has spent billions of years drifting through interstellar space before entering the Solar System. Chemical Composition and Spectral Evidence The spectral properties of an object provide critical insight into its...

have remained largely unchanged since their formation in the cold, outer regions of the protoplanetary disk. Mapping the Solar System’s Chemistry The study suggests that the organic matter was synthesized through grain chemistry or the radiation-driven...

chaos varied significantly between models, with some scenarios witnessing the total expulsion of planets from the solar system, while others saw Uranus and Neptune swapping their orbital positions. Simulations show how the dying Sun could shake up...

New study suggests a massive asteroid shattered 800 million years ago, unleashing a debris wave that swept through the inner Solar System. New calculations suggest that a catastrophic breakup of a parent body in the main asteroid belt around 800...

A 2026 outburst reshaped Comet 220P/McNaught, painting it green as astrophotographers snapped stunning shots over Namibia. Astrophotographers Gerald Rhemann and Michael Jäger captured a vivid view of Comet 220P/McNaught on August 8, 2026, when the...

New JWST observations reveal how shifting winds in young solar systems may strip away the essential gas required to build planets. New data from the James Webb Space Telescope (JWST) is reshaping our understanding of how infant planetary systems shed...

Observations of WOH G64 suggest the massive red supergiant may be nearing a supernova, but new evidence of titanium oxide in its atmosphere complicates its true identity and evolutionary path. WOH G64 is a massive star located in the Large Magellanic...

Astronomers have discovered a rare baby planet less than 1 million years old, providing a unique glimpse into the earliest stages of planetary formation. Astronomers have confirmed the existence of Elias 2-24 b, a massive infant world that currently...

NASA is developing a 99-meter starshade designed to block starlight, allowing ground-based telescopes to capture images of Earth-like rocky exoplanets. Detecting an Earth-like world remains one of the most formidable challenges in modern astronomy....

NASA astronauts finish pivotal spacewalk to ready the ISS for upgraded solar power systems, boosting station energy capacity. On 6 August, NASA astronauts Jessica Meir and Anil Menon completed a 6‑hour‑plus extravehicular activity that placed the last...

A heavy, rusty “rock” found in an Australian goldfield turned out be something far rarer than gold: a meteorite that preserves untouched material from the early solar system. The Maryborough meteor is one of the most intriguing space rocks found in...

Study finds the asteroid that ended the dinosaurs was a rare CO chondrite, with fine atmospheric debris—not sulfur—driving the global extinction. A new analysis of nickel isotopes trapped in the thin clay layer that marks the Cretaceous‑Paleogene...

Could a shared astronomical alignment help Earth coordinate first contact with distant civilizations? Scientists are now testing this interstellar theory. Astronomers are reimagining the search for extraterrestrial intelligence by shifting the focus...

Neptune, are believed to be migrants from the Kuiper Belt beyond Pluto. Because their orbits intersect with those of the solar system’s giant planets, these bodies remain gravitationally unstable over millions of years. Researchers have long theorized...
