In 1908 something exploded over a remote part of Siberia with the force of roughly 1,000 Hiroshima bombs, flattened 80 million trees, and was heard 600 miles away — and more than a century later, scientists still cannot fully agree on whether it was an asteroi - Space Daily

On the morning of June 30, 1908, the sky over a remote stretch of Siberian forest split open. Eyewitnesses — and there were only a handful, because almost nobody lived there — described a column of bluish light, nearly as bright as the sun, moving across the …

Every GPS satellite is launched with a clock deliberately set to run slow, because Einstein's relativity speeds it up by about 38 microseconds a day once in orbit — and without that built-in correction, your phone's location would drift by roughly ten kilometres a d - Space Daily

Every GPS satellite is launched with a clock deliberately set to run slow, because Einstein's relativity speeds it up by about 38 microseconds a day once in orbit — and without that built-in correction, your phone's location would drift by roughly ten kilometres a d - Space Daily

Every satellite in the GPS constellation carries atomic clocks, and before launch those clocks are deliberately set to tick at the wrong rate. They are adjusted to run slightly slow. The offset is small and precise, and it is built in on the ground, on purpos…

Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness - Phys.org

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. The solution provides insight into high-dimensional r…

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 - Space Daily

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 …
