NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early solar system trapped on stable orbits associated with — but not close to — the planet Jupiter. NASA’s Lucy in the L4 Trojans Participating Scientist Program supports scientists to carry out new investigations … Read more
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid. Lucy will pass within 596 miles … Read more
That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft. Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is covered with a layer of ice, and below that ice, we … Read more
A new international study partially funded by NASA on how Mars got its iconic red color adds to evidence that Mars had a cool but wet and potentially habitable climate in its ancient past. The current atmosphere of Mars is too cold and thin to support liquid water, an essential ingredient for life, on its … Read more
So how long does it take to get from Earth to the Moon, to Mars or to Jupiter? As with most things in life, the answer is: it depends. During the Apollo program, when NASA sent humans to the Moon, those missions took several days to reach the Moon. The fastest of these was Apollo … Read more
Why does the Moon look larger on the horizon? The short answer is, we don’t know. We’ve been talking about this for 2,000 years. Aristotle mentions it. And in our own time, scientists are designing experiments to figure out exactly what’s going on. But there’s no consensus yet. Here’s what we do know. The atmosphere … Read more
The Moon will pass into Earth’s shadow and appear to turn red on the night of March 13 or early in the morning of March 14, depending on time zone. Here’s what you need to know about the total lunar eclipse. The March 2025 total lunar eclipse will take place between late night on March … Read more
Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme. Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake Superior, but … Read more
NASA’s powerful James Webb Space Telescope includes asteroids on its list of objects studied and secrets revealed. A team led by researchers at the Massachusetts Institute of Technology (MIT) in Cambridge repurposed Webb’s observations of a distant star to reveal a population of small asteroids — smaller than astronomers had ever detected orbiting the Sun in the main … Read more
These celestial objects look like asteroids but act like comets now come in two flavors. The first dark comet — a celestial object that looks like an asteroid but moves through space like a comet — was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce … Read more
