The Overview Effect: Astronaut Perspectives from 25 Years in Low Earth Orbit

To see Earth from space is to be forever changed by the view. Since Alan Shepard became the first American to lay eyes on our home planet from above, countless NASA astronauts have described feeling awed by the astonishing sight and a profound shift in perspective that followed. This unique experience is known as the […]

Hubble Captures Puzzling Galaxy

This NASA/ESA Hubble Space Telescope image features a galaxy that’s hard to categorize. The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (the Crab). NGC 2775 sports a smooth, featureless center that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star […]

Europa Clipper Captures Uranus With Star Tracker Camera

Description NASA’s Europa Clipper captured this image of a starfield — and the planet Uranus — on Nov. 5, 2025, while experimenting with one of its two stellar reference units. These star-tracking cameras are used for maintaining spacecraft orientation. Within the camera’s field of view — representing 0.1% of the full sky around the spacecraft […]

NASA’s Quesst Mission Marks X-59’s Historic First Flight

NASA’s X-59 quiet supersonic research aircraft took off for its historic first flight on Oct. 28, 2025, at 11:14 a.m. EDT from Lockheed Martin Skunk Works in Palmdale, California. The one-of-a-kind aircraft flew for 67 minutes before landing and taxiing to NASA’s Armstrong Flight Research Center in Edwards, California.
