NASA’s Lucy Spacecraft Images Asteroid Donaldjohanson

4 min read NASA’s Lucy Spacecraft Images Asteroid Donaldjohanson In its second asteroid encounter, NASA’s Lucy spacecraft obtained a close look at a uniquely shaped fragment of an asteroid that formed about 150 million years ago. The spacecraft has begun returning images that were collected as it flew approximately 600 miles (960 km) from the asteroid Donaldjohanson on April 20, 2025.

NASA’s Lucy probe will fly by the asteroid Donaldjohanson on Easter Sunday

Easter Sunday certainly won’t be a day of rest for the astronomy community. All eyes will be on NASA’s asteroid-studying Lucy spacecraft, which is due to have a close encounter at 1:51 p.m. EDT (1751 GMT) on April 20, 2025. Launched in 2021, Lucy is on a 12-year journey to the orbit of Jupiter, during which the probe will perform flybys of eight Trojan asteroids in a quest to learn about the origins of the solar system, searching for elements that could spark the rise of life. But before Lucy gets…

We now know the shape of notorious asteroid 2024 YR4 that dominated headlines recently — it’s probably ‘suburban,’ too

The asteroid 2024 YR4 — the one that caused a stir earlier this year due to its potential collision course with Earth — has a surprising tale to tell. A new study reports that this space rock likely hails from the central region of the main asteroid belt between Mars and Jupiter — a cosmic “suburb” scientists don’t typically associate with asteroids that cross paths with our planet. Shortly after its discovery late last year, astronomers calculated that 2024 YR4 had a 1.3% chance (1-in-83) of impacting Earth in December…

‘City-killer’ asteroid 2024 YR4 could hit the moon instead of us, scientists say

An asteroid that’s big enough to wipe out a city has a 1-in-43 chance of hitting our planet in the year 2032. But according to new calculations, there’s an even smaller chance that it might crash into the moon instead. On Feb. 7, NASA scientists increased the likelihood of asteroid 2024 YR4 colliding with Earth on Dec. 22, 2032, nearly doubling the odds from 1.2% to 2.3%. The potentially hazardous asteroid measures an estimated 180 feet (55 meters) across — about as wide as Walt Disney World’s Cinderella Castle is…

What the asteroid with a 1-in-48 chance of hitting Earth in 2032 looks like (images)

It might not look like much in this image, but this is the asteroid that has made a major news impact in 2025. That’s because this space rock, designated asteroid 2024 YR4, has a 1-in-48 chance of impacting Earth in 2032. For obvious reasons, astronomers are desperate to learn as much as they can about 2024 YR4, estimated to be as large as 177 feet wide (54 meters wide). That’s around as wide as Cinderella’s Castle in Walt Disney World Florida is tall. The image featured here was captured on…

Earth is bombarded with rocks from space — but who gets to keep these ultimate antiques?

Every day, about 48.5 tons of space rock hurtle towards Earth. Meteorites that fall into the ocean are never recovered. But the ones that crash on land can spark debates about legal ownership. Globally, meteorite hunting has become a lucrative business, with chunks of alien rock traded online and shipped between countries. Meteorites hold the key to the mysteries of the universe, but increasingly, significant scientific finds are being lost to private collectors. Last year, New Zealand formally recorded an apple-sized meteorite weighing 810g. It fell on Department of Conservation…

NASA’s Webb Reveals Smallest Asteroids Yet Found in Main Asteroid Belt

Illustration of the main asteroid belt, orbiting the Sun between Mars and Jupiter NASA 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 asteroid belt between Mars and Jupiter. The 138 new asteroids range from the size of a bus to the size of a…
