A fossil site in North Dakota appears to have captured the day the dinosaur-killing asteroid struck Earth, right down to tiny glass beads from the impact lodged in the gills of fish that died within hours - Space Daily

A fossil site in North Dakota appears to have captured the day the dinosaur-killing asteroid struck Earth, right down to tiny glass beads from the impact lodged in the gills of fish that died within hours - Space Daily

The site is called Tanis, in the Hell Creek Formation of southwestern North Dakota. In 2019, a team led by Robert DePalma described it as a rare snapshot of the first minutes to hours after the Chicxulub asteroid impact 66 million years ago. The most arrestin…

Researchers simulated 30 million routes to the Moon and found a hidden detour through L1 that saves fuel and keeps spacecraft talking to Earth the whole way - Space Daily

An international team of researchers has identified a new fuel-efficient route between Earth and the Moon that also avoids the kind of communications blackout the Artemis II crew experienced when their spacecraft slipped behind the lunar far side in April. Th…

The Cassini spacecraft was deliberately flown into Saturn in 2017 because NASA refused to risk contaminating Enceladus, and in its final 90 seconds its thrusters fought the atmosphere so it could keep sending data home - Space Daily

Mysterious Earthquakes Strike Like Clockwork – We May Finally Know Why - ScienceAlert

For more than three decades, experts have been trying to solve the mystery of why a certain kind of underwater fault triggers earthquakes way more predictably than others.

The Voyager Golden Record carries a small sample of uranium on its cover, placed there so that whoever finds it can measure the decay and work out how long it has been drifting — a built-in clock for a message engineered to last around a billion years. - Space Daily

Each of the two Voyager spacecraft, launched in 1977, carries a phonograph record. The records hold sounds and images chosen to represent Earth, assembled by a committee led by Carl Sagan. The records themselves are the part most people know about. The cover …

When they reach the bottom of a soap dispenser, frugal handwashers might try adding water to the bottle to push out the last bit of soap. But usually, the water drills right through the soap and jets out an only slightly sudsy splash.
