Jupiter's Great Red Spot storm, which usually appears dark-red, can be seen shining a lurid blue color in an ultraviolet image of the planet.

The asteroid is estimated to be between 656 and 1,443 feet across, and will pass at 16 times the distance to the moon.

A little-known chapter of the Hubble Space Telescope’s history is a reminder of the risks of looking at the sun

With the installation of a charged particle detector on Dec. 3, 2024, all 10 of NASA's Interstellar Mapping and Acceleration Probe (IMAP) science instruments have been fully integrated on the spacecraft.

"Some of the extreme ultraviolet light above active regions flickers erratically for a few hours before a solar flare," researcher Emily Mason said.

"The question 'Are we alone?' is one of the most significant questions, not just in the history of science, but in the history of humanity."

NASA noted that a particularly strong El Niño — a natural climate fluctuation — that began in fall 2023 likely pushed the average temperature up in 2024. Plus, scientists are still studying the effects of events like the January 2022 Tonga volcanic eruption,

Pandora, NASA's newest exoplanet mission, is one step closer to launch with the completion of the spacecraft bus, which provides the structure, power and other systems that will allow the mission to carry out its work.

SpaceX plans to launch the seventh full-scale test flight of its massive Super Heavy booster and Starship rocket Thursday afternoon. It's the first of what might be a dozen or more demonstration flights this year as SpaceX tries new things with the most powerful rocket ever built.

With that in mind, Rocket Lab this week urged NASA to immediately launch an official commercial competition for MSR, and open up the project to competing bids. As Rocket Lab argues, other companies' proposals will probably cost between $5.8 billion and $7.7 billion, and won't be ready to go until at least 2035, maybe as long as 2039.

Firefly Aerospace's first mission to the moon is poised to launch in the early morning hours on Jan. 15. The company's Blue Ghost lunar lander is sharing a payload bay with another mission to the moon's surface,
