Chasing sprites in electric skies! Must watch!
Paul Smith is a night-sky fanatic and photographer. His obsession is sprites: immense jolts of light that flicker high above thunderstorms. Last October, he guided NASA scientist Dr. Burcu Kosar through the backroads of Oklahoma to catch one herself. Although she’d studied sprites for more than 15 years, she hadn’t yet chased one.

watch a live lunar eclipse recorded by NASA !
Go outside with NASA and watch the total lunar eclipse! On the evening of May 15, Earth will pass between the Sun and the Moon, blocking sunlight and casting a shadow on the lunar surface. Starting at 9:32 p.m. EDT (1:32 UTC on May 16), people with clear skies in the Americas, Europe, and parts of Africa will begin to see the Moon get bathed in the red glow of every sunrise and sunset refracted through Earth’s atmosphere. Totality will occur at 12:12 a.m. EDT on May 16 (4:12 UTC).
Join NASA experts to learn about this incredible natural phenomenon, look through telescope views across the world, and hear about plans to return humans to the lunar surface with the Artemis program. Have questions? Ask them in our live chat.

amazing visuals of the moon in 4K!! mindblowing close up of moon
This video uses data gathered from the Lunar Reconnaissance Orbiter spacecraft to recreate some of the stunning views of the Moon that the Apollo 13 astronauts saw on their perilous journey around the farside in 1970. These visualizations, in 4K resolution, depict many different views of the lunar surface, starting with earthset and sunrise and concluding with the time Apollo 13 reestablished radio contact with Mission Control. Also depicted is the path of the free return trajectory around the Moon, and a continuous view of the Moon throughout that path. All views have been sped up for timing purposes — they are not shown in "real-time."

NASA captures shocking footage of 133 days on the sun! must watch !
On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time lapse. There are usually only a few bright regions visible at a time and they shift and flash like small fires. From these regions there are wispy loops reaching up above the surface that rapidly change shape and size.
On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun.

How Do Spacecraft Slow Down? We Asked a NASA Technologist
How do spacecraft slow down? Rigid heat shields and retropropulsion have been the favorites of engineers for years. Now NASA is testing a new inflatable heat shield technology that could allow us to carry even larger payloads to worlds with atmospheres: https://www.nasa.gov/loftid
