Space exploration presents unique health challenges for astronauts due to lack of gravity, isolation, and radiation exposure. ESA's SciSpacE activities aim to comprehend these effects and their implications for human well-being during extended missions.
If this tech demonstration is successful, the system could one day allow astronauts to converse by laser.
The moon will have a close encounter with Saturn on Wednesday, Aug. 30 as the ringed gas giant sits just below the full Super Blue Moon.
The third episode of Ahsoka reminds us of George Lucas' stance on the Jedi Order and the Force without sacrificing the sense of adventure and wonder.
A dead star feeding on a stellar companion seems to have two brightness modes. It's because, astronomers discovered, the system launches cosmic cannonballs.
While we wait for Avatar 3 to arrive in 2025, James Cameron and Ubisoft plan to keep us busy with the open-world video game Avatar: Frontiers of Pandora.
NASA will discuss the September arrival of asteroid samples collected by its OSIRIS-REx probe during a press conference today (Aug. 30), and you can watch it live.
An instrument aboard the mission’s Pragyan rover has found traces of sulfur within the lunar south pole’s soil.
Skywatchers get to see a second full moon this month on Wednesday (Aug. 30), and it is a special one: A rare unification of a Blue Moon and a "supermoon."
The two most powerful space telescopes ever built, NASA’s James Webb Space Telescope (JWST) and Hubble Space Telescope, are about to gather data about the most volcanically body in the entire solar system, Jupiter’s first Galilean Moon, Io. This data will be used in combination with upcoming flybys of Io by NASA’s Juno spacecraft, which is currently surveying the Jupiter system and is slated to conduct these flybys later this year and early 2024. The purpose of examining this small, volcanic moon with these two powerful telescopes and one orbiting spacecraft is for scientists to gain a better understanding of how Io’s escaping atmosphere interacts with Jupiter’s surrounding magnetic and plasma environment.
The U.S. National Science Foundation reported that a cybersecurity incident has temporarily shut down operations at its Gemini North Telescope in Hawaii and Gemini South Telescope in Chile.
The Whirlpool Galaxy, aka M51, is one of the most well-known objects in the night sky. It’s close enough and prominent in the northern sky that amateur astronomers have shared stunning pictures of it for decades. But you’ve never seen anything like this: M51 as seen by the James Webb Space Telescope (JWST). This image contains data from the telescope’s NIRCam and MIRI instruments, which shows incredible detail and reveals hidden features among the spiral arms.
Ever since the first direct observations of the solar wind in 1959, astronomers have worked to figure out what powers this plasma flow. Now, scientists using the ESA/NASA Solar Orbiter spacecraft think they have an answer: tiny little outbursts called “picoflares” They flash out from the corona at 100 kilometers per second.
Space junk could one day be snatched in orbit with a strong bag, if a new contract to test the technology ends up flying in space.
After years of build-up and anticipation, the James Webb Space Telescope finally launched into orbit on December 25th, 2021 (what a Christmas present, huh?). Since then, the stunning images and data it has returned have proven beyond a doubt that it was the best Christmas present ever! After its first year of operations, the JWST has lived up to one of its primary objectives: to observe the first stars and galaxies that populated the Universe. The next-generation observatory has accomplished that by setting new distance records and revealing galaxies that existed less than 1 billion years after the Big Bang!
A rare temperature-sensitive molecule usually found in stars has been discovered in the atmosphere of an exoplanet for the first time, a marshmallow-like hot Jupiter called WASP-31b.
Satellites watched as a temporary city sprang up in the Nevada desert, where the famed Burning Man "radical self-expression" festival kicked off on Monday (Aug. 28).
A James Webb Space Telescope image of M51 boasts amber hues and reddish streaks, capturing the galaxy's gravitational relationship with a neighboring realm.
Weather satellites in orbit above Earth are watching Hurricane Idalia and Hurricane Franklin as they pick up strength in ocean waters off the southern coast of the United States.
When you think of a black hole, you might think its defining feature is its event horizon. That point of no return not even light can escape. While it’s true that all black holes have an event horizon, a more critical feature is the disk of hot gas and dust circling it, known as the accretion disk. And a team of astronomers have made the first direct measure of one.
