Astronomers found evidence that the Milky Way's disc was flipped over 90 degrees about 10 billion years ago after a head-on collision with a dwarf galaxy called the Gaia Sausage, long before the solar system formed. Supercomputer simulations by Durham University researchers explain the slow rotation of stars in the Milky Way's halo.
Recent space and geological discoveries include unexplained compounds on Pluto and Titan, identified repeating radio signals, deep space sugar molecule, Earth's potential Sun avoidance, and more.
Astronomers detected an atmosphere on LHS 1140b, a super-Earth in a habitable zone 49 light-years from Earth, by analyzing escaping helium. While no evidence of life exists, the discovery makes LHS 1140b a prime target for astrobiology studies.
Smaller Indian cities are leading rooftop solar adoption, with households in Lucknow, Nagpur, and Surat seeing reduced electricity bills. The Pradhan Mantri Surya Ghar Muft Bijli Yojana has driven installations, benefiting over 44 lakh households, while major metros lag behind.
Odisha is integrating the PM Surya Ghar scheme with housing projects like PMAY, offering subsidized rooftop solar systems. This aims to reduce electricity costs for low-income households and improve housing affordability.
Controversial Harvard cosmologist Avi Loeb, known for his theories on alien life, is heading a new, secret US scientific advisory panel on UFO security risks. The panel, which has requested Pentagon data, aims to analyze unidentified aerial phenomena (UAP) from a national security perspective, though some critics question Loeb's unconventional approach and lack of security experience.
Astronomers suggest comet 3I/Atlas, the third observed interstellar visitor, may be up to 12 billion years old, predating our solar system. Its unique chemical composition, detected by the James Webb telescope, indicates formation in a very cold environment, unlike any known solar system body.
A new analysis suggests interstellar comet 3I/ATLAS could be 7 billion years old, potentially making it older than our Solar System. Discovered in July 2025, its unusual features initially sparked speculation about artificial origins, but the Oxford model points to an ancient natural object from the Milky Way's thick disk.
A new study suggests humanity lacks the technology to rule out the presence of extraterrestrial probes or artifacts in the Solar System. Current observations cover only a tiny fraction of space in sufficient detail, making detection difficult.
A study analyzing 122 scenarios of solar system instability suggests Uranus' moons, particularly Miranda, show evidence of a violent past involving now-ejected giant planets, supporting the hypothesis of the solar system once having more planets.
The SETI Institute has announced that extensive radio scans of an interstellar comet have revealed no signs of alien technology. The comet, the third known object from another star to enter our solar system, was observed by SETI's telescope in Northern California.
