More than 6,000 exoplanets confirmed in the Milky Way, including rocky worlds
6+ hour, 48+ min ago (290+ words) More than 6,000 exoplanets have been confirmed in the Milky Way, including terrestrial worlds that may be composed mainly of rock and metal. The NASA Exoplanet Archive listed 6,366 confirmed planets as of September 11, 2026, along with thousands of additional candidates awaiting verification....
A backyard astronomer from Broken Hill has contributed to a world-first space discovery
15+ hour, 23+ min ago (112+ words) From a backyard in Broken Hill, a former mine worker has helped make a world first planetary discovery. Trevor Barry has spent years tracking Saturn from the backyard observatory he built himself. In July 2024, Trevor first noticed something unusual around…...
New simulations suggest the moon formed just 5 hours after Earth slammed into protoplanet Theia
8+ hour, 24+ min ago (552+ words) Earth's moon may have formed far faster than scientists once believed, with new simulations suggesting it came together in as little as five hours after a catastrophic collision. That unexpectedly short timeline could reshape researchers' understanding of one of the…...
We Are Probably Not Alone
3+ hour, 54+ min ago (702+ words) Ever since the discovery of exoplanets, more than 4000 of these have been discovered in space. Many of them have very similar properties as Earth, so it is possible that …...
Fermi Paradox: Astronomers Keep Finding Earth-Like Worlds.
8+ hour, 26+ min ago (28+ words) Why Haven’t We Found Anyone Living on Them? — WhatIfScience With every Earth-like planet discovered, the odds of life elsewhere seem to …...
A molecular-hydrogen cloud only 300 light-years away spans roughly 40 full-Moon widths across our sky, yet astronomers did not identify it until 2025. Named Eos, it escaped conventional surveys because they search for molecular hydrogen indirectly through carbon monoxide—and almost all of Eos is CO-dark.
13+ hour, 29+ min ago (858+ words) Eos covers about 20 degrees of sky, but almost all its estimated 3,400 solar masses of molecular hydrogen escaped the carbon-monoxide surveys normally used to find such clouds....
Frozen object beyond Jupiter is transforming into a comet
1+ day, 21+ hour ago (1029+ words) A frozen object beyond Jupiter is venting carbon dioxide gas into space, revealing what can drive activity so far from the sun. A centaur, one of the icy bodies that orbit beyond Jupiter, has started venting gas into space, even…...
Pluto’s Atmosphere May Be Collapsing - Eos
1+ day, 22+ hour ago (539+ words) It takes Pluto 248 years to complete one journey around the Sun. Humanity has known of its existence for less than half of that time, and we are still discovering the myriad ways that Pluto is unlike other celestial objects. Among…...
ALMA Finds Interstellar Comet 3I/ATLAS Loaded With Methanol
3+ day, 5+ hour ago (137+ words) The ALMA radio telescope in Chile has measured an unusually high methanol content in the coma of interstellar comet 3I/ATLAS, among the highest ever recorded in any comet. The ratio of methanol to hydrogen cyanide came out at roughly 70 on…...
Astronomer Theorise That Extraterrestrial Megacomputers Could Soon Reveal Hidden Alien Civilisations
3+ day, 2+ hour ago (541+ words) The idea begins with a simple premise about civilisation itself. Computers have become steadily more powerful and central to human life, and the paper asks whether advanced extraterrestrial societies might also push computation towards its most efficient possible form, making…...
