- NASA’s NEOWISE Extends Legacy With Decade of Near-Earth Object Data As the infrared space telescope continues its long-duration survey of the universe, it is creating a unique resource for future astronomers to make new discoveries. NASA’s NEOWISE mission has released its 10th year of infrared data – the latest in a unique long-duration (or “time-domain”) survey that captures how celestial objects change over long periods.

- NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk. When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide (170-meter-wide) asteroid on Sept. 26, 2022, it made its mark in more ways than one. The demonstration showed [&#8230;]
- NASA’s Planetary Radar Images Slowly Spinning Asteroid During the close approach of 2008 OS7 with Earth on Feb. 2, the agency’s Deep Space Network planetary radar gathered the first detailed images of the stadium-size asteroid. On Feb. 2, a large asteroid safely drifted past Earth at a distance of about 1.8 million miles (2.9 million kilometers, or 7 1⁄2 times the distance [&#8230;]
- NASA System Predicts Impact of a Very Small Asteroid Over Germany The Scout impact assessment system calculated where and when the asteroid 2024 BX1 would impact Earth’s atmosphere, providing a useful demonstration of planetary defense capability. A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET). At 95 minutes before it impacted [&#8230;]
- NASA’s NEOWISE Celebrates 10 Years, Plans End of Mission The asteroid and comet-hunting infrared space telescope has gathered an impressive haul of observations, but it’s now at the mercy of the Sun, which is accelerating its demise. NASA’s NEOWISE has had a busy decade. Since its reactivated mission began on Dec. 13, 2013, the space telescope has discovered a once-in-a-lifetime comet, observed more than [&#8230;]
- Data From NASA’s WISE Used to Preview Lucy Mission’s Asteroid Dinkinesh Researchers have utilized infrared survey data to refine the asteroid’s size and surface brightness in support of the Nov. 1 encounter by NASA’s Lucy mission. NASA’s Lucy mission will soon have its first asteroid encounter as the spacecraft travels through deep space en route to Jupiter’s orbit. But before the spacecraft passes 265 miles (425 [&#8230;]
- Earth May Have Captured a 1960s-Era Rocket Booster In 1966, NASA launched Surveyor 2 to the Moon. Now its rocket booster has apparently returned to near-Earth space. Earth has captured a tiny object from its orbit around the Sun and will keep it as a temporary satellite for a few months before it escapes back to a solar orbit. But the object is [&#8230;]
- ‘Echo Mapping’ in Faraway Galaxies Could Measure Vast Cosmic Distances Matter swirling around supermassive black holes creates bursts of light that “echo” in nearby dust clouds. These traveling signals could serve as a new cosmic yardstick. When you look up at the night sky, how do you know whether the specks of light that you see are bright and far away, or relatively faint and [&#8230;]
- School Bus-Size Asteroid to Safely Zoom Past Earth Roughly 15 to 30 feet wide, the object will make its closest approach on Sept. 24. A small near-Earth asteroid (or NEA) will briefly visit Earth’s neighborhood on Thursday, Sept. 24, zooming past at a distance of about 13,000 miles (22,000 kilometers) above our planet’s surface. The asteroid will make its close approach below the [&#8230;]
