Jared Isaacman is set to appear before lawmakers once again for a hearing to become NASA’s next Senate-confirmed administrator.
The vantage point at Cerro Pachón, with its dark skies and high-altitude clarity, enhances the richness of the image.
Astronomers have spotted a distant world "shedding" its atmosphere into space in real time, creating a giant cloud of helium gas that sweeps across its parent star well before the planet itself.
Auroras may be visible from Alaska to New York as a speedy solar wind and incoming coronal mass ejection are expected to buffet Earth's magnetic field.
There’s been a lot of speculation recently about interstellar visitor 3I/ATLAS - much of which is probably caused by low quality data given that we have to observe it from either Earth, or in some case Mars. In either case it’s much further away that what would be the ideal. But that might not be the case for a future interstellar object. The European Space Agency (ESA) is planning a mission that could potentially visit a new interstellar visitor, or a comet that is making its first pass into the inner solar system. But, given the constraints of the mission, any such potential target object would have to meet a string of conditions. A new paper, available in pre-print on arXiv, by lead author Professor Colin Snodgrass of the University of Edinburgh of his colleagues, discusses what those conditions are, and assesses the likelihood that we’ll find a good candidate within a reasonable time of the mission's launch.
Asteroid Bennu samples contain life-friendly sugars, a strange "space-gum," and ancient stardust
True to its promise, the European Space Agency’s EarthCARE satellite is now being used to calculate directly how clouds and aerosols influence Earth’s energy balance – the all-important balance that regulates our climate. In doing so, EarthCARE is poised to sharpen the accuracy of climate models, the very tools that guide global climate policy and action.
Is it an insect? A strange fossil? An otherworldly eye, or even a walnut? No, it’s an intriguing kind of martian butterfly spotted by ESA’s Mars Express.
A SpaceX Falcon 9 rocket carrying 29 Starlink broadband internet satellites launched from the Cape Canaveral Space Force Station in Florida on Tuesday, Dec. 2, 2025.
Looking to level up your photography gear? Black Friday and Cyber Monday are behind us, but if you're fast, you can still save big on these final few camera deals, from Canon, Sony and Nikon.
Veteran cosmonaut Oleg Artemyev was taken off SpaceX's Crew 12 mission to the International Space Station after violating ITAR regulations, according to the Russian publication The Insider.
Measuring the time discrepancy between Earth and Mars will help make future navigation and communication systems on the Red Planet more accurate.
All eight of the International Space Station's docking ports are currently occupied by visiting spacecraft, marking a milestone for crewed spaceflight.
The Butterfly Nebula is one of those cosmic objects that demands our attention, and even our fascination. It's also known as NGC 6302 or the Bug Nebula, but whatever name we use, the stunning spectacle of ionized gases draws our human eyes in. In fact, Butterfly and its nebulae brethren may be more responsible for generating public enthusiasm in astronomy than any other type of object.
It's not too late to get a great Cyber Monday drone deal, as the DJI Mavic 4 Pro is still $500, but there aren't many left, so you'll have to be quick.
The life of a star is a fascinating journey, governed by its initial mass. Stars are born in dense regions of gas and dust known as nebulae.
The European Space Agency member states have approved a record-breaking budget for the next three years, including increased funding for science exploration.
China's space agency has announced it will return a damaged spacecraft back to Earth without crew after a suspected debris strike left it unfit for flight.
Cyber Monday may be behind us, but there are still a few deals to be had. We've rounded up the remaining bargains, so snap these up before they're gone!
Suppose you slammed together two neutrons at near-luminous speed. The resulting collision would create a cascade of particles from protons, electrons, and neutrinos to more exotic fare. We can't predict the exact number or type of particles produced, but we do know one thing: the total charge of all the particles would be zero. This is because charge is a conserved quantity, and since the neutrons have zero total charge, their resulting particles must have the same.
The U.S. Senate will hold its second hearing to consider billionaire tech entrepreneur Jared Isaacman's nomination for NASA chief on Wednesday (Dec. 3), and you can watch the action live.
