Earth and the Martian moon Phobos dance together in a series of images recently acquired by NASA’s Perseverance Mars rover. Earth appears as a point of light in the Martian sky, disappearing behind the crescent of Phobos, the larger of…
The annual Perseid meteor shower is scheduled to peak this August 11-12. Cross your fingers for good weather, find a nice dark spot to bring a blanket or lounge chair, and get ready to relax and spot some meteors.
Using continuous imagery from NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, scientists predicted the near-Earth arrival of a solar eruption to within 30 minutes in an initial proof of concept test. The results, presented Tuesday at the…
A solar eclipse, the Perseids, bright Venus after sunset, and a deep partial lunar eclipse highlight August’s skywatching. Skywatching Highlights Transcript A solar eclipse, one of the year’s best meteor showers, Venus at its brightest in the evening sky, and…
If you live in the Northern Hemisphere and look up during July evenings, you’ll see the brilliant star Vega shining overhead. Did you know that Vega is one of the most studied stars in our skies? As one of the brightest summer…
As NASA’s Curiosity rover recently began climbing up a Martian valley nicknamed “Valle Grande,” it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each one about 1.5 to 3 inches (4 to…
Editor’s note: An update to this story was made on July 30, 2026, to share information about NASA’s live eclipse broadcast. Each time the Moon covers the Sun during a total solar eclipse — darkening daytime skies and briefly revealing…
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth-based auroras. Results published Thursday in Nature Communications show…
Lee esta historia en español aquí. NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system.…
Background Human exploration of Mars will expose crews to a persistent, fine particulate environment whose physicochemical properties and health implications remain only partly understood. Because no samples of authentic Martian airborne dust have been returned to Earth, NASA must rely…
