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 down. The resulting brightness changes are so dramatic that it is the most variable planetary-mass object known to date. The…
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…
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 California. Their effects, both hazardous and beneficial, are felt globally.
A new study using NASA data shows that a recently…
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…
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 its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
Massive stars race…
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…
Pi Day Challenge: Solve Stellar Math Problems With NASA
March 10, 2023
Pi Day is the annual tribute to the mathematical constant pi, whose infinite number of decimals is usually rounded to 3.14. So what better day to celebrate than March 14? To find pi, aka the Greek letter π, you simply divide any circle’s circumference by its diameter. It’s a ratio that’s indispensable to NASA missions studying Earth, Mars, and beyond.
This Pi Day marks the 10th year that…
