Sea level data gathered Jan. 21 in the Gulf Stream by SWOT’s KaRIn instrument, visualized at left, has 10 times the spatial resolution of data taken over the same area by altimeters on seven other satellites, visualized at right. Red represents sea levels higher than the global average, while blue is lower. Credit: left: NASA/JPL-Caltech; right…
Researchers observing with NASA’s James Webb Space Telescope have pinpointed silicate cloud features in a distant planet’s atmosphere. The atmosphere is constantly rising, mixing, and moving during its 22-hour day, bringing hotter material up and pushing colder material…
After two days of fast-paced competition complete with team uniforms, cheerleaders, pounding music, and blaring horns, multiple teams of high schoolers came out victorious at the 23rd annual FIRST Robotics Competition Los Angeles Regional over the weekend. Next, they’ll be…
The average global sea level rose by 0.11 inches (0.27 centimeters) from 2021 to 2022, according to a NASA analysis of satellite data. That’s the equivalent of adding water from a million Olympic-size swimming pools to the ocean every day for a year, and is part of a multidecade trend of rising seas.
Since satellites began observing sea surface height in 1993 with the U.S.-French TOPEX/Poseidon…
Atmospheric rivers – vast airborne corridors of water vapor flowing from Earth’s tropics toward higher latitudes – can steer much-needed rain to parched lands. But in extreme form, they can also cause destruction and loss of life, as recently occurred in parts of…
Since NASA launched the 2001 Mars Odyssey Orbiter to the Red Planet almost 22 years ago, the spacecraft has looped around Mars more than 94,000 times. That’s about the equivalent of 1.37 billion miles (2.21 billion kilometers), a distance that has required extremely…
NASA’s Magellan Data Reveals Volcanic Activity on Venus
March 16, 2023
Direct geological evidence of recent volcanic activity has been observed on the surface of Venus for the first time. Scientists made the discovery after poring over archival radar images of Venus taken more than 30 years ago, in the 1990s, by NASA’s Magellan mission. The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year.

The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with…
As Christmas approached last year, astronomers and space fans around the globe gathered to watch the much-anticipated launch of the James Webb Space Telescope. Though a wondrous piece of engineering, the telescope was not without its controversies — from being way over…
NASA scientists have strong evidence that Jupiter’s moon Europa has an internal ocean under its icy outer shell – an enormous body of salty water swirling around the moon’s rocky interior. New computer modeling suggests the water may actually be pushing the ice shell along, possibly speeding up and slowing down the rotation of the moon’s icy shell over time.
Scientists have known that…
