JUICE Jupiter probe spotted 1 million miles from Earth (video, image)
An Earth-based telescope spotted Europe's JUICE spacecraft as it zooms toward Jupiter to study the giant planet's mysterious, icy ocean moons.
What Cassini’s “Grand Finale” Taught Us About Saturn’s Interior
Six years ago the Cassini spacecraft, which had spent nearly two decades in orbit around Saturn, finished its mission with a grand finale, plunging itself into the depths of Saturn’s atmosphere. Those last few orbits and the final plunge revealed a wealth of information about Saturn’s interior. A team of astronomers have collected all of the available data and are now painting a portrait of the interior of the solar system’s second largest planet.
Stratolaunch's huge Roc plane drops hypersonic test vehicle for 1st time (video)
Stratolaunch's giant Roc airplane dropped a prototype of the company's Talon hypersonic vehicle in mid-air for the first time during a test flight on Saturday (May 13).
62 New Moons Found for Saturn
Jupiter is the King, Earth is teeming with life, Venus is a weird, spacecraft-crushing hellhole, and now Saturn has the most moons. Again.
James Webb Space Telescope discovers water around a mysterious comet
The James Webb Space Telescope has imaged a rare main asteroid belt comet, discovering water around the object that could help reveal how Earth became a wet planet teeming with life.
ESA Wants Your Ideas for Living off the Land… on the Moon
Challenges have been a mainstay of space exploration for several years at this point. In the past, they have ranged from making a potential space elevator to designing a solar power system on the Moon. The European Space Agency is continuing that tradition and has recently released a new challenge focusing on lunar resources. Called the Identifying Challenges along the Lunar ISRU Value Chain campaign, this new ESA platform is the next step in the agency’s efforts to develop an entire “value chain” of in-situ resource utilization (ISRU) technologies.
Two Super-Earths Found Orbiting a Red Dwarf Star at the Edge of the Habitable Zone
NASA’s Transiting Exoplanet Survey Satellite, or TESS, was designed to find other worlds. Following in the tradition of the Kepler spacecraft, TESS has a hundred thousand stars looking for small but regular dips in their brightness. These dips are typically caused by planets as they pass in front of the star. TESS has been quite effective, logging nearly 6,000 candidate exoplanets. Confirming or rejecting these candidates takes time, but it has led to some interesting discoveries.
Saturn's rings are much younger than we thought
Saturn's rings are surprisingly youthful and much younger than the gas giant planet itself, new research has revealed.
'Foundation' season 2 launches July 14 on Apple TV+. Watch the new teaser (video)
A thrilling new preview trailer for "Foundation" season 2 has just landed from Apple TV+ for its July 14 premiere.
Watch Nick Fury return in this 'Secret Invasion' behind-the-scenes featurette from Marvel Studios (video)
Marvel Studios has dropped a fresh behind-the-scenes trailer for June's "Secret Invasion" series, offering a glimpse as Nick Fury's return.
The most powerful black holes in the universe may finally have an explanation
Quasars, the most extreme phenomena in the universe, are triggered when galactic collisions deliver gas to feeding black holes, new research suggests.
The Moon Occults Jupiter Wednesday Morning for North America
Be sure to set your alarm for early Wednesday morning, as the Moon occults the King of Planets.
Webb finds water, and a new mystery, in rare main-belt comet
The NASA/ESA/CSA James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for Solar System scientists studying the origins of the water that has made life on Earth possible. Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapour – around a comet in the main asteroid belt for the first time, proving that water from the primordial Solar System can be preserved as ice in that region. However, the successful detection of water comes with a new puzzle: unlike other comets, Comet 238P/Read had no detectable carbon dioxide.
Confirmed. Ultra-Luminous X-Ray Sources are Really That Bright
At the extreme end of astrophysics, there are all sorts of phenomena that seem to be counter-intuitive. For example, how can an object not possibly get any brighter? For a long time, this limit, known as the Eddington limit, was thought to be an upper bound on how bright an object could be, and it was directly correlated with the mass of that object. But observations showed that some objects were even brighter than this theoretical limit, and now data collected by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) confirms that these objects are, in fact, breaking the Eddington limit. But why?
The James Webb Space Telescope May Have Spotted a Baby Galaxy Merger
New JWST images reveal that one of the most distant objects ever observed is actually two baby galaxies on a possible collision course.
Photographers capture the exact moment a gargantuan storm blasts out of the sun during a total solar eclipse
A stunning composite image of the sun during a recent 'hybrid eclipse' in Australia is further proof that solar activity is ramping up.
Scientists Confirm: Meteorite Crashed Into New Jersey Home
A rock that crashed through the roof of a house in New Jersey proved to be the real thing — a chunk spalled from a 4.5 billion-year-old asteroid.
Black Holes Might be Defects in Spacetime
A team of theoretical physicists have discovered a strange structure in space-time that to an outside observer would look exactly like a black hole, but upon closer inspection would be anything but: they would be defects in the very fabric of the universe.
The Earth's Magnetosphere Could be Used as a Gravitational Wave Observatory
One of the challenges of gravitational wave astronomy is moving its abilities beyond observations of stellar mass mergers. The collision of two black holes or neutron stars releases a tremendous amount of gravitational energy, but even this is a challenge to detect. Gravitational waves do not couple strongly with most matter, so it takes a tremendous amount of sensitive observations to observe. But we are getting better at it, and there are a few proposals that hope to take our observations even further. One example of this is a recent study that looks at utilizing the magnetospheres of Earth and Jupiter.
50 years ago, Skylab launched into orbit. See what it meant to an astronaut on a space station now.
Stephen Bowen remembers seeing Skylab fly overhead. At eight years old, Bowen's experience fueled his interest in spaceflight. Little did he know where that would take him 50 years later.
