An amateur astronomer searching satellite maps for a Quebec camping spot accidentally discovered a massive ancient impact crater. Scientists later found shatter cones that confirmed the ...
NASA’s Roman Space Telescope has successfully activated its 300-megapixel infrared camera, which will capture enormous stretches of the cosmos with Hubble-like sharpness. Its planet-hunting coronagraph is also working as expected, putting Roman ...
NASA’s Roman Space Telescope may now have enough fuel for at least 22 years of science, more than double its original 10 year design life. An extremely precise course correction, extra fuel at ...
A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth and even through our bodies. What began as a student physics project is now being used in major experiments, balloon missions, ...
Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA’s Deep Space Food Challenge, the system can produce proteins, fats, ...
Solar sails pushed by powerful lasers could reach incredible speeds, but relativity may eventually make the light itself work against them. At around 75% of the speed of light, scattered photons can begin creating drag, adding a surprising obstacle ...
NASA has brought two of Swift’s telescopes back online after technical problems derailed a commercial mission intended to rescue the aging observatory by raising its orbit. With atmospheric drag pulling the spacecraft downward faster than ...
NASA’s Roman Space Telescope has launched on a million mile journey to L2, where it will scan huge portions of the cosmos for clues about dark matter, dark energy, and distant worlds. With survey ...
NASA’s Roman Space Telescope will combine Hubble-like detail with a field of view 100 times larger, giving astronomers a sweeping new way to explore the cosmos. Its observations could uncover hidden planets, map billions of cosmic objects, and ...
NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known orbits of more than 200 space objects completely ...
NASA’s Roman Space Telescope is now enclosed inside its Falcon Heavy fairing and nearly ready for launch. Its mission could uncover thousands of exoplanets while helping scientists investigate dark matter, dark energy, and the accelerating ...
NASA’s Roman Space Telescope has been cleared for final launch preparations ahead of a targeted August 30 liftoff aboard SpaceX’s Falcon Heavy. The powerful new observatory will probe cosmic expansion, the history of the universe, and distant ...

The James Webb Space Telescope has revealed surprising changes in the rings around Chariklo, a small object orbiting between Saturn and Uranus. Over just a few years, its inner ring became more ...

Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an ...

A huge 10-sided atmospheric pattern has appeared around Saturn’s south pole, giving the planet a surprising counterpart to its famous northern hexagon. Hubble data suggest the strange decagon only ...

Astronomers have detected an exceptionally faint hydrogen radio signal from billions of light-years away using South Africa’s MeerKAT telescope. Instead of finding galaxies one at a time, the ...

September’s sky features brilliant Venus, the Milky Way’s hazy center, and the seasonal turning point of the equinox. The month ends with a glowing Harvest Moon rising near Saturn and faint ...

Star formation across the universe has fallen dramatically over the past 4.5 billion years, but astronomers have uncovered a surprising twist: the supply of neutral hydrogen, a key ingredient for ...

NASA and SpaceX have delayed Crew-13 after finding an oxidizer leak in the Dragon spacecraft’s propulsion system during prelaunch preparations. Engineers are investigating the problem before the ...

Scientists have discovered that Mercury’s surface contains far less silicon dioxide than previously thought, pointing to an unexpectedly hot volcanic past. The finding suggests ancient lava may ...

A century-old mystery in Venus’s clouds just became more intriguing, as scientists calculated how strongly the unidentified material behind its dark ultraviolet patterns must absorb light. The ...

Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help explain several long-standing ...

NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares of its youth. Those events may help ...

A magnetar with an astonishingly powerful magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago. Its light shows signs that supposedly empty space is ...

The Artemis II crew will receive the Congressional Space Medal of Honor after becoming the first humans in more than 50 years to travel beyond the Moon. Their 10-day Orion mission also carried them ...

Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more ...

Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ...

Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with ...

Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for ...

NASA scientists found that microbes brought by astronauts could survive in cold, shadowed niches around the Moon’s South Pole, potentially complicating future searches for pristine lunar chemistry. ...

Astronomers have identified a surprisingly young population of fading radio galaxies whose supermassive black holes have already switched off their powerful jets. The confirmed remnants range from ...
