Dark Matter May Behave Like Ordinary Matter Under Gravity, New Study Finds
A new study shows dark matter falls into cosmic gravity wells much like ordinary matter, narrowing one of astronomy’s biggest mysteries. Researchers say any unknown force acting on dark matter must be very weak, though future missions could detect smaller effects. The findings bring scientists closer to understanding how the universe’s unseen mass behaves.

Interstellar Visitor 3I/ATLAS Brightens Faster Than Expected, Surprising Scientists
The interstellar comet 3I/ATLAS has brightened far faster than expected during its solar approach, surprising researchers. Scientists say the unusual surge may point to rare chemical traits from another star system. Further observations in 2025 may reveal why this cosmic visitor behaves differently from typical comets in our solar neighbourhood.

Point Nemo: The Remote Ocean Graveyard Where the ISS Will Make Its Final Descent in 2030
NASA will retire the ISS in 2030, sending it to Point Nemo, a remote Pacific zone known as the spacecraft cemetery. Most of the station will burn up during reentry, with remaining debris falling harmlessly into the sea. The controlled descent aims to avoid past mishaps and reflects a new era of commercial space stations.

Ghostly Neutrinos May Hold the Answer to Why Matter Exists in Our Universe
In a breakthrough study, scientists merged data from Japan’s T2K and the U.S. NOvA neutrino experiments to explore why matter exists in the universe. The findings improve measurements of neutrino behavior and may help reveal whether these particles break symmetry with antimatter, offering vital clues to how the universe survived after the Big Bang.

German Scientists Develop Laser Drill to Explore Icy Moons’ Hidden Oceans
Scientists from TU Dresden have created a laser drill that vaporises ice to reach potential subsurface oceans on Europa and Enceladus. Lighter and more energy-efficient than mechanical drills, it enables deep exploration with minimal power, paving the way for studying icy worlds and their potential for extraterrestrial life.

Japan’s Akatsuki Spacecraft Declared Inoperable, Marking End of Dedicated Venus Missions
Japan’s Akatsuki spacecraft, which studied Venus for nearly a decade, has been declared inoperable by JAXA. Successfully orbiting in 2015 after an initial failure, Akatsuki uncovered major insights into Venus’s swirling clouds and atmosphere. Its mission’s end leaves a gap until NASA’s VERITAS and DAVINCI+ missions take over.
Kevin Rose’s simple test for AI hardware — would you want to punch someone in the face who’s wearing it?
“As an investor, you kind of have to not only say, okay, cool tech, sure, but emotionally, how does it make me feel? And how does it make others feel around me?”
