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 from the asteroid Donaldjohanson on Sunday, April 20.

The asteroid Donaldjohanson as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI) on NASA’s Lucy spacecraft during its flyby. This timelapse shows images captured approximately every 2 seconds beginning at 1:50 p.m. EDT (17:50 UTC), April 20, 2025. The asteroid rotates very slowly; its apparent rotation here is due to the spacecraft’s motion as it flies by Donaldjohanson at a distance of 1,000 to 660 miles (1,600 to 1,100 km). The spacecraft’s closest approach distance was 600 miles (960 km), but the images shown were taken approximately 40 seconds beforehand, the nearest ones at a distance of 660 miles (1100 km).

Earth Information Center

For more than 50 years, NASA satellites have provided data on Earth's land, water, air, temperature, and climate. NASA's Earth Information Center allows visitors to see how our planet is changing in six key areas: sea level rise and coastal impacts, health and air quality, wildfires, greenhouse gases, sustainable energy, and agriculture.

NASA’s Kennedy Space Center shares boundaries with the refuge, which is home to more than 330 native and migratory bird species, along with 25 mammal, 117 fish, and 65 amphibian and reptile species.

Fuzzy Rings of a Dying Star

NASA’s James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique mid-infrared observations. Webb shows its rings as intricate clumps of dust. It’s also easier to see holes punched through the bright pink central region.
