Astronomers missed a space explosion as powerful as a billion suns — until they spotted its echo
A cosmic explosion with an energy equivalent to the output of a billion suns went unnoticed by astronomers until they caught the "echo" of this gamma-ray burst.
Scientists solve 12,800-year-old climate mystery hidden in Greenland ice
A mysterious spike of platinum buried deep in Greenland’s ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago—possibly triggering a sudden return to icy conditions known as the Younger Dryas. But new research points to a far less dramatic, yet still powerful culp

A not-so-equal equinox: Why day beats night on the 1st day of spring
The spring equinox marks the first day of spring today, but daylight actually lasts several minutes longer than night. Here's why the equinox doesn't appear perfectly equal.
Astronomers discover nearby galaxy was shattered by cosmic crash
A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created the illusion that its gas was rotating. The discov
Scientists turn CO2 into fuel using breakthrough single-atom catalyst
Researchers have created a cutting-edge catalyst that turns CO2 into methanol more efficiently than ever before. Instead of using clumps of metal atoms, they engineered a system where each single indium atom actively drives the reaction. This dramatically reduces energy needs while making the proces
