New mapping in Australia has revealed a strange dent in the magnetic field beneath the country’s Northern Territory. The Australia Magnetic Anomaly, named after its similarity in shape to the country, holds valuable information about Australia’s geological history, including how different rock layers formed and acquired their distinctive magnetic properties. “Magnetic data allows us to
One of the universe’s largest stars, previously predicted to be in the throes of a violent supernova death, may not imminently explode after all, a new study suggests. The surprise finding also hints that the stellar “behemoth” is slowly being cannibalized by a smaller, hidden partner. WOH G64, often dubbed the “behemoth star,” is a
Jupiter’s ice-covered moon Europa appears to have life-friendly molecules on its surface. Al Emran, a researcher with NASA‘s Jet Propulsion Laboratory, spotted ammonia on the surface of Europa while looking through old data from the Galileo mission, which studied Jupiter and its moons from 1995 to 2003. Data gathered from Galileo’s near-infrared mapping spectrometer in
The Turritopsis dohrnii is a small, bell-shaped jellyfish found in temperate and tropical waters. It has stinging tentacles and is completely transparent, allowing you to see its pulsating internal organs. It’s a predator and hunts in the open ocean, feeding on small crustaceans and plankton. An adult Turritopsis dohrnii jellyfish. This deep-water, alien-seeming creature has

The superhydrophobic design could lead to resilient ships, floating platforms, and renewable energy innovations. More than a century after the Titanic sank, engineers still have hopes of someday creating “unsinkable” ships. In a
As humanity moves from brief space missions toward longer stays — driven by commercial ambitions for moon bases and eventual Martian settlements — scientists are beginning to confront how the conditions of space may affect human reproduction. A new study argues that the absence of clear evidence and shared standards around reproductive health beyond Earth
In the early 1960s, Dutch astronomer Adriaan Blaauw observed stars moving at unusually high speeds moving through the Milky Way. These stars, as it turned out, were unbound objects that had been kicked out of the Milky Way and periodically looped back and forth through the disk. Blaauw proposed that these stars originated in binary
For all we’ve learned about places far away in outer space, we may have barely scratched the surface of the places lying deep within Earth. As a result, there’s a lot of information we seem to be missing out on—for example, the influence of two huge rock blobs on Earth’s magnetic field. In a Nature
Jupiter has had its length and breadth measured again, and it turns out the giant planet is skinnier and shorter than scientists had thought. “Textbooks will need to be updated,” said Yohai Kaspi of the Weizmann Institute in Israel in a statement. “The size of Jupiter hasn’t changed, of course, but the way we measure
