The Milky Way ate another galaxy. Scientists say they’ve found the scraps
An unusual collection of stars may represent the remnants of a dwarf galaxy that the Milky Way devoured about 10 billion years ago.
Something ‘unprecedented’ is now happening to Earth’s rotation, scientists say | BBC Science Focus Magazine
Climate change is slowing Earth’s spin – and there’s nothing quite like it in 3.6 million years
Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness
Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn’t believe it would ever be solved. …
In 1990, after years of lobbying by Carl Sagan, Voyager 1 turned its camera back toward home from about 6 billion kilometres away and photographed Earth as a pale blue speck smaller than a single pixel — an image NASA had repeatedly resisted because it offered little scientific value, but that became one of the most famous photographs ever taken.
On 14 February 1990, the Voyager 1 spacecraft turned its cameras back toward the inner solar system and photographed the planets it had left behind. Among the 60 frames was one that caught Earth: a point of light less than a single pixel across, sitting in a band of scattered sunlight. The image became known […]
China merges space programmes as race to the moon with US heats up
The country releases further details about how it is ‘combining experiences and expertise’ from its crewed and uncrewed lunar missions.
Voyager 1 is now so far from Earth that a signal traveling at the speed of light takes more than 22 hours to reach it — so when engineers send a command, they can wait nearly two days to know whether the spacecraft responded
Sending a command to Voyager 1 is closer to mailing a letter than placing a phone call. The probe, launched in September 1977, is now roughly 16 billion miles from Earth, heading away from the Sun at roughly 38,000 miles per hour. In November 2026, Voyager 1 will become the first human-made object to pass […]

Heavily reddened quasars caught going through a ‘blow-out’ phase
At the center of most large galaxies sits a supermassive black hole (SMBH). When these black holes are actively consuming material, they become incredibly luminous quasars. But some quasars appear wrapped …
The Atlantic Ocean Was Hiding a Massive Freshwater Reservoir Big Enough to Supply NYC for 800 Years
Scientists have discovered a massive freshwater reservoir buried beneath the Atlantic Ocean, stretching from New Jersey to Maine — and early estimates suggest it could hold enough water to supply New York City for nearly 800 years. Researchers believe the reservoir dates back to the last ice age, though it could take years to determine whether the water can — or should — ever be tapped.
Astronomers Spent 160 Years Trying to Explain This Star’s Strange Signal. A White Dwarf Hidden in Its Orbit May Have Finally Solved the Mystery
A star at the heart of Cassiopeia has baffled science since 1866, until lost Soviet research and a Japanese X-ray telescope changed everything.
