NASA’s Nancy Grace Roman Space Telescope is now aiming for an earlier launch in September 2026. Designed to explore dark matter, dark energy, and distant exoplanets, the telescope will capture massive, ultra-detailed surveys of the cosmos using ...
NASA is testing a next-generation space computer chip that could give spacecraft the ability to operate far more independently in deep space. The radiation-hardened processor is showing performance levels hundreds of times beyond current spaceflight ...
NASA’s Roman Space Telescope could expose a vast hidden population of neutron stars lurking unseen across the Milky Way. By detecting subtle shifts in starlight caused by gravity, the mission may ...
Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By ...
NASA’s Psyche spacecraft is about to pull off a dramatic close flyby of Mars, skimming just 2,800 miles above the planet to get a powerful gravitational boost on its journey to the mysterious metal-rich asteroid Psyche. The maneuver will save ...
NASA’s Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed “Atacama” — the entire chunk ripped loose from the ground and stayed stuck to the rover’s drill. Engineers watched as Curiosity shook, ...
A bold step toward returning humans to the Moon is underway with Blue Origin’s uncrewed MK1 “Endurance” lander, designed to test the technologies that future astronauts will rely on. Built in ...
A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory. Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached ...
Artemis II proved NASA’s deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad ...
Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space. The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going. Despite the shutdown, it continues to ...
Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way. By analyzing millions of stars, the system has ...
A group of undergraduate students pulled off something remarkable: they built their own dark matter detector and used it to probe one of physics’ biggest mysteries. Working with limited resources but plenty of creativity, they designed a ...

Dante’s Inferno may have been far more than a religious epic. New research argues that the 14th-century poet essentially imagined a catastrophic asteroid impact centuries before modern science ...

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black ...

A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A “lonely” hot Jupiter — typically found without nearby ...

Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe. A massive galaxy, formed less than 2 billion years after the ...

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, ...

A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets. Using the James Webb Space Telescope, researchers studied LHS 3844 b—a ...

A mysterious comet from beyond our solar system is giving astronomers a rare glimpse into alien worlds — and it may have formed in a place far colder and stranger than anything around our Sun. The ...

Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models. By directly imaging Epsilon Indi Ab with the James Webb Space ...

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a telltale U-shaped pattern showing that star formation drops sharply ...

Curiosity has detected a surprising variety of organic molecules on Mars, including compounds tied to the chemistry of life. Some of these molecules may be billions of years old, preserved in ancient ...

As the Moon swallowed the Sun during the April 8, 2024, total solar eclipse, something remarkable happened on the ground—cities went eerily quiet. Scientists analyzing seismic data found that ...

Scientists have captured stunning new insights into one of the universe’s most powerful phenomena—black hole jets—by using a planet-sized network of radio telescopes. Focusing on Cygnus X-1, ...

A massive cosmic milestone has just been reached: scientists have completed the largest high-resolution 3D map of the universe ever created. Built using data from over 47 million galaxies and ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s faster than early-Universe models predict. By linking multiple ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers ...

Earth’s nights are steadily getting brighter overall, but the changes vary dramatically by region. Rapid urban growth is lighting up countries like China and India, while parts of Europe are ...

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...

A group of undergraduate students stumbled into a cosmic time capsule—one of the oldest stars ever discovered—while combing through massive astronomy datasets. What began as a class project ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands ...

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself. New research suggests ...
