A malevolent, screaming skull face. A witch cackling in profile. An all-seeing eye, gazing red and furious from the void of space. Like cosmic Halloween decorations, nebulas are some of the most gorgeous objects in the universe, and some of the spookiest. These vast regions of gas and dust, illuminated by starlight and sculpted by … Read more
After more than a year together on the Red Planet, NASA’s Perseverance rover and its hitchhiking “pet rock” have finally parted ways. The stone had been lodged in one of the rover’s wheels for more than half of its mission on Mars. Perseverance accidentally picked up the pet rock in its front left wheel on … Read more
After 65 years of lunar exploration, the United States is finally going to put its first autonomous rover on the moon. But this mission won’t be helmed by NASA engineers — instead, it is the brainchild of a dedicated group of college students. The Iris rover was developed by students, faculty and alumni at Carnegie Mellon … Read more
Five years ago, NASA’s infrared Spitzer Space Telescope helped discover a family of seven rocky exoplanets orbiting the same star, known as TRAPPIST-1. Now, NASA’s new infrared powerhouse — the James Webb Space Telescope (JWST) — measured the temperature of one of those worlds, TRAPPIST-1b, in new research published in the journal Nature. The bad … Read more
Planetary scientists have found groundbreaking evidence of recent volcanic activity on Venus. Archives from NASA’s Magellan mission show telltale signs that Maat Mons, a 5-mile-high (8 kilometers) volcano on Earth’s hellish twin, was active in 1991. Magellan, launched in May 1989, was the first spacecraft to map the entire surface of Venus. The mission’s radar … Read more
Scientists studying the surface of Mars recently found a piece of the rocky planet smiling back at them. In an image shared Jan. 25 by The University of Arizona (opens in new tab) (UA), what appears to be the face of an enormous Martian teddy bear — complete with two beady eyes, a button nose … Read more
NASA has revealed plans to create a nuclear-powered rocket that could send astronauts to Mars in just 45 days. The agency, which has partnered with the Pentagon’s Defense Advanced Research Projects Agency (DARPA) to design the rocket, announced on Tuesday (Jan. 24) that it could build a working nuclear thermal rocket engine as soon as … Read more
Astronomers have uncovered more than 400 previously hidden black holes feeding on stars and dust in the center of galaxies. It appears that many of the new black holes, discovered using NASA’s Chandra X-ray Observatory, remained unknown until now because they are buried beneath cocoons of dust. Supermassive black holes, which can be millions of … Read more
An ancient, dried-up lake bed on Mars may be teeming with opal gemstones, new data from NASA’s Mars Curiosity rover suggests. Beyond giving the cracked surface of Mars’ Gale Crater a semiprecious glint, these opals could be evidence that water and rock have been interacting beneath the Martian surface much more recently than was previously … Read more
A towering dust storm that engulfed the Mars Perseverance rover in September 2021 was a colossal 390.4 feet (119 meters) tall, the first-ever audio recording of a dust devil on the surface of Mars reveals. The recording, an analysis of which was published Tuesday (Dec. 13) in the journal Nature Communications (opens in new tab), … Read more
