NASA recently showed off its new underwater rover that it hopes one day could help in exploring alien ocean worlds in the search for life. The robot, known as Buyant Rover for Under-Ice Exploration (BRUIE), is designed to crawl under an ice cap. Right now, it is being tested in Antarctica, in hopes one day it could go to ocean worlds ...

Nearly a year after it was supposed to launch, NASA has finally assembled the James Webb Space Telescope, the long-awaited successor to the Hubble Space Telescope. The government agency said the two halves of the telescope were joined earlier this week in Redondo Beach, Calif., where engineers used a crane to put the telescope together. The next step is to ...

Earth’s oceans have made it the perfect environment for biodiversity, but a new study suggests that it may not have the best conditions in the galaxy. The study suggests that exoplanets that have “favorable ocean circulation patterns” could be better suited to support a wider range of life than Earth. “This is a surprising conclusion,” said lead researcher Dr. Stephanie ...

The Hubble Space Telescope has spotted a “jellyfish”-like star deep in space, located in the Orion constellation. The space telescope snapped the picture of the star, known as NGC 2022, a so-called “red giant,” showing the ancient star expanding to a size larger than our sun. “When stars like the sun grow advanced in age, they expand and glow red,” Hubble ...

Shortly before the start of World War II, Albert Einstein, perhaps the world’s most famous theoretical physicist, wrote a letter to a colleague detailing his thoughts on the “power of the resistance” of the Jewish people. And now that letter is set to go up for auction and it could fetch a staggering sum. The letter, postmarked June 10, 1939, ...

Video grab from the incredible footage of a 14-day-old polar bear cub and its mother at Berlin Zoo, shot using cutting-edge camera technology. (Credit: SWNS) There’s only one word to describe this — aww. A polar bear cub no bigger than a guinea pig was caught on video at the Berlin Zoo snuggling with its mother, SWNS reports. The cub is just ...

Earth’s natural history may now serve as a guide for astronomers to spot exoplanets. About 500 million years ago, this planet had a different light signature due to the dominance of moss. About 300 million years ago, ferns dominated and mature plant forms rule today – strengthening our planet’s light signature (Jack O’Malley-James/Wendy Kenigsberg/Brand Communications). Earth’s history could be useful ...

A 3D-printed Twitter logo is seen through broken glass, in this picture illustration taken February 8, 2016. (REUTERS/Dado Ruvic/Illustration) Fair Play for Women, a self-described “group of ordinary women” who say they are concerned their voices will not be heard when it comes to transgender laws, have accused Twitter of making a “concerted attack on women’s free speech.” In a ...
