El Niño and the 2024 Total Solar Eclipse
What will the ongoing El Niño event do to the chance of cloud cover along the 2024 total solar eclipse track?
It's Time for a Gravitational Wave Observatory in the Southern Hemisphere
What’s true for optical astronomy is also true for gravitational wave astronomy: the more observatories you have, the better your view of the sky. This is why the list of active gravitational wave observatories is growing. But so far they are all in the Northern Hemisphere. As a recent article on the arXiv points out, that means we are missing out on a good number of gravitational events.
Wired for space - Muscle stimulation to enhance astronaut health
Video: 00:05:10
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.
SpaceX resupply mission will bring NASA laser communication system to ISS this year
If this tech demonstration is successful, the system could one day allow astronauts to converse by laser.
See Saturn snuggle up to the Super Blue Moon in the night sky tonight
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 last Super Blue Moon until 2037 rises tonight. Here's how to see it
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."
Exploring Io’s Volcanic Activity via Hubble and Webb Telescopes
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.
Hackers shut down 2 of the world's most advanced telescopes
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, Seen by JWST
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.
Is the Solar Wind Coming From These Tiny Jets on the Sun?
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.
Private company wants to clean up space junk with 'capture bags' in Earth orbit
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.
JWST Plucks One Single Star out of a Galaxy Seen 12.5 Billion Years Ago
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!
Bizarre super-puffy exoplanet hosts rare 'thermometer molecule'
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.
