Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]

Nine out of 10 Americans have a chemical called bisphenol A in their urine, said Nicholas D. Kristof. BPA, which can be found in plastic food containers, soup can linings, ATM receipts, and many other consumer products, is a proven “endocrine disruptor”—a substance that mimics or alters human hormones. Studies have already linked BPA to breast cancer, diabetes, and hyperactivity, […]

But a new study has revealed that the drug also dulls emotions—including happiness. Prior research showed that acetaminophen can help take the sting out of negative feelings like dread, but the new findings from Ohio […]

The Milky Way and its closest neighbor, the Andromeda galaxy, are on course for “ a head-on collision,” says astronomer Roeland van der Marel of the Space Telescope Science Institute. But no need for precautions because the crash won’t happen for another 4 billion years. Researchers have long known that Andromeda, currently some 2.5 million light-years away, is moving toward […]

A huge research ship costing £200 million has been commissioned, which will probe the oceans and climate of the arctic and Antarctic. They are the cruel seas where Britain’s greatest adventurers made their names. Now the territory of Scott and Shackleton, will be surveyed by a new generation of British explorers who will tackle the ‘final frontier’ of Earth’s […]

Mysterious radio signals from space have been known to repeat, but for the first time, researchers have noticed a pattern in a series of bursts coming from a single source half a billion light-years from Earth. Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don’t repeat. But repeating fast […]

With temperatures in excess of 800 F, Mercury is one of the last places in the solar system you’d expect to find ice. But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy […]
