NASA’s LRO Finds Photo Op as It Zips Past SKorea’s Danuri Moon Orbiter

NASA’s LRO (Lunar Reconnaissance Orbiter), which has been circling and studying the Moon for 15 years, captured several images of Korea Aerospace Research Institute’s Danuri lunar orbiter last month. The two spacecraft, traveling in nearly parallel orbits, zipped past each other in opposite directions between March 5 and 6, 2024.

How NASA’s Roman Telescope Will Measure Ages of Stars

Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the […]

Rock Sampled by NASA’s Perseverance Embodies Why Rover Came to Mars

The 24th sample taken by the six-wheeled scientist offers new clues about Jezero Crater and the lake it may have once held. Analysis by instruments aboard NASA’s Perseverance Mars rover indicate that the latest rock core taken by the rover was awash in water for an extended period of time in the distant past, perhaps […]

NASA’s Europa Clipper Survives and Thrives in ‘Outer Space’ on Earth

A gantlet of tests prepared the spacecraft for its challenging trip to the Jupiter system, where it will explore the icy moon Europa and its subsurface ocean. In less than six months, NASA is set to launch Europa Clipper on a 1.6-billion-mile (2.6-billion-kilometer) voyage to Jupiter’s ocean moon Europa. From the wild vibrations of the […]

ESA, NASA Solar Observatory Discovers Its 5,000th Comet

On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed […]

Hubble Tracks Jupiter’s Stormy Weather

The giant planet Jupiter, in all its banded glory, is revisited by NASA’s Hubble Space Telescope in these latest images, taken on January 5-6, 2024, capturing both sides of the planet. Hubble monitors Jupiter and the other outer solar system planets every year under the Outer Planet Atmospheres Legacy program (OPAL). This is because these large […]

On Jan. 19, 2024, at 10:20 a.m. EST, the JAXA (Japan Aerospace Exploration Agency) Smart Lander for Investigating Moon (SLIM) landed on the lunar surface. Five days later, NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft passed over the landing site and photographed SLIM. LRO acquired the image at an altitude of about 50 miles (80 km). […]
