On September 27, 2025, Hurricane Humberto reached its peak intensity as a Category Five hurricane well northeast of Puerto Rico on its journey across the western Atlantic Ocean. The polar orbiting satellite Suomi-NPP captured a spectacular view of the clear eye of Humberto. (1/5)
This image of Hurricane Humberto contains the visible (band I1) product from the S-NPP weather satellite from 17:10 UTC on 2025-09-27.

Melanie Metz is one of the most famous storm chasers in the world. We traveled around North Dakota with her to learn why she loves to capture extreme weather.

Well, forget what I said, turns out you can process marsrover images on the train too :)

There is a super faint smudge where comet 3I/Atlas should be. The new orbit parameters in Stellarium are a pretty good match. 🔭 #3iatlas

Continuous activity of 🌋in Saunders is (S. Atlantic). MODIS image of a long #volcanotrack with a good #sentinel overpass (line). The latter shows how the puffs from the top ascend and mix with existing clouds which become brighter. It is most obvious in NIR bands, not so much in VIS bands.

#NASAWebb has found the first direct evidence of potential moon formation around a giant exoplanet. The discovery is shedding light on how such systems evolve and why moons could be potentially habitable worlds: https://bit.ly/46xGodN 🔭 🧪
An illustration of a young planet with a surrounding disk of dust and gas potentially forming moons. The planet, which appears dark red, is shown at lower right, circled by a cloudy, clumpy reddish orange-colored disk. The host star appears at upper left, and glows yellow, with its own reddish disk of debris. The disk that surrounds the planet takes up about half the illustration. The black background of space is speckled with stars. At the bottom of the illustration, graphics of molecules are listed in the following order: Acetylene, Carbon Dioxide, Ethane, Benzene, Hydrogen cyanide. The words Artist’s Concept appear at upper right.

This satellite image highlights the confluence of three of Guyana’s major rivers—the Cuyuni, the Mazaruni, and the Essequibo. Darker waters likely contained less suspended sediment. Light brown waters likely contained enormous amounts of fine-grained sediment🧪

A moderately strong M6.4 solar flare was detected this morning around AR 4232 at 08:43 UTC (Sept 28). So far the event does not look to be the source of an Earth directed CME. Image by SDO/AIA.
