A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]

Often likened to Agent Mulder from “The X-Files,” he worked for Britain’s defense ministry and became a leading commentator on extraterrestrial matters.

There’s no sign reading “home sweet home” in the hangar where the X‑59 now sits, but the sentiment is unmistakable among those tending to the quiet supersonic aircraft. Located at NASA’s Armstrong Flight Research Center in Edwards, California, the X-59 hangar was built in 1968 but looks like new thanks to a full renovation and […]

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 clay-rich rocks that once held water. One standout find resembles building blocks of DNA, raising exciting questions about Mars’ past. Although not proof of life, the discovery suggests the Red Planet may have once been far more biologically promising than we thought.

By Earth Resources Observation and Science (EROS) Center For more than 50 years, Landsat has imaged Earth’s land and near-shore surfaces as the satellites descend in midmorning orbit, when daily sunlight is optimal. That’s just what they’ve always done. Currently, Landsat 8 and Landsat 9 circle the globe while also making better use of their ascending paths, […]

Description NASA’s Curiosity Mars rover captured this 360-degree view of a region filled with low ridges called boxwork formations between Nov. 9 and Dec. 7, 2025 (the 4,714th to 4,741st Martian days, or sols, of the mission). At 1.5 billion pixels, this is one of the largest panoramas Curiosity has ever taken (the rover’s largest […]

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed wave-like interference in positronium, an exotic “atom” made of an electron and its antimatter partner, a positron. This breakthrough not only strengthens the weird reality of quantum mechanics but also opens the door to new experiments involving antimatter, including the possibility of testing how gravity affects it—something never directly measured before.

A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA’s Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first time in years and at power levels exceeding any previous test in the United States, a team fired up […]

Dreams are more structured than they seem, shaped by both personal traits and real-world experiences. Researchers found that the brain doesn’t just replay daily life—it reshapes it into imaginative, sometimes surreal scenarios. People who mind-wander more tend to have fragmented dreams, while those who value dreams experience richer ones. Even major events like the pandemic changed dream content, making it more emotional and restrictive.

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 quasars, this map could unlock new clues about dark energy—the mysterious force driving the universe’s expansion. Despite setbacks like wildfire disruptions, the international DESI collaboration powered through, gathering an unprecedented dataset that already hints dark energy may behave in unexpected ways.
