Scientists thought the exceptionally quiet Sun of 2008 might be slipping into a decades-long lull. Instead the trend reversed, and a NASA study published in September 2025 found that its underlying solar-wind activity has been strengthening for nearly two decades.
JWST found an object in the early universe whose dense hydrogen cocoon made it look eerily like an enormous star — until astronomers realized it was radiating roughly 100 billion times the Sun’s luminosity, with a growing black hole hidden inside.
A telescope array still in early construction was pointed at the Helix Nebula and came back with 22 arcs of shocked gas in the faint outskirts — each one carved by an invisible clump of a dead star’s ejecta that interstellar space is pulling apart
Two of Neptune’s tiny inner moons contain clay minerals that could not have formed on worlds so small and cold — suggesting they’re built from the exposed interiors of much larger moons shattered when the captured Kuiper Belt world Triton tore through Neptune’s original satellite system billions of years ago.
Thought of the day from Stoic philosopher Marcus Aurelius: “Let not future things disturb you, for you will come to them, if it shall be necessary, with the same reason which now you use for present things.”
Astronomers announced in January 2026 that they had found a 710-metre asteroid — nearly eight football fields across — spinning once every 1.88 minutes. A normal rubble-pile asteroid should tear itself apart at anything close to that speed, meaning 2025 MN45 must have internal strength comparable to solid rock.
Right now, without moving a muscle, you are aboard a planet orbiting the Sun at 107,000 kilometres per hour, inside a solar system orbiting the galaxy at 720,000 kilometres per hour, while the Milky Way and Andromeda close on each other at roughly 400,000 kilometres per hour — and you cannot feel any of it.
A drone caught Maserati the dolphin lifting a football-sized shell to trap a fish, then her calf picking it up and trying the same
A 250-seat jet is being built with four aisles instead of one. The reason is the shape: when you blend wings directly into a body wide enough to hold a small apartment, a single corridor down the middle no longer makes any sense
In April 2026, scientists reported that Curiosity had detected the first nitrogen heterocycle on the Martian surface — a class of organic molecule that on Earth forms part of the chemical pathway toward RNA and DNA. It isn’t evidence of life, but it shows that ancient Mars possessed surprisingly complex prebiotic chemistry.
Scientists reported phosphine in Venus’s clouds in 2020, then watched the finding come under fierce attack. But years of follow-up observations have repeatedly recovered the signal with far more data, while no known non-biological process has yet been shown to produce the claimed amounts.
SpaceX spent $15.8 billion building AI compute infrastructure in just three months — more than four times what its entire Space division spent on capital projects throughout 2025. And Elon Musk is already warning that global chip production isn’t scaling fast enough to meet AI demand.
