A reconstruction of the inner heliosphere for the last 18 months and 926 coronal mass ejections. This is a new method: The ambient solar wind at the inner boundary is produced from the near-Earth observations. The CMEs are still determined by coronagraph observations.

JWST 🔭 infrared images reveal complex H3+ ionospheric emission above and around Jupiter's Great Red Spot. Possible cause: gravity waves from the lower atmosphere breaking in ionosphere. Science paper: nature.com/articles/s4155… Press release: le.ac.uk/news/2024/june…

今朝はペルセウス座流星群が活発でしたね!2024年8月13日3時26分58秒に流れたペルセウス座流星群の火球を、平塚から撮影しました。娘と一緒にひそひそ話しながら観測していて、これが初めて娘が見た流星になりました!緑色の禁制線の光が美しく、上空の風で少しずつ流星痕の形が変化していきました。

The framing of this question as reasonable cannot be accepted. We shouldn’t be asking if getting into tens of thousands of pounds of debt is ‘worth it’ for university students. We should be asking why there is any debt at all.

Water across the Solar System: - Moon: Found in permanently shadowed craters and within rocks - Mars (1.5 AU): Exists as surface ice, a subsurface ocean, and in the atmosphere - Ceres (asteroid belt, 2.7 AU): Possibly up to 25% water ice - Jupiter (5.2 AU): Subsurface oceans on

#Saturn emerging from behind the moon after Wednesday morning's #occultation. An MP4 video made from 100 stacked images from a single 10,000 frame AVI taken through my telescope. Playing at 10 frames/second. Single video. No composite #animation #astrophotography #ThePhotoHour

1/2 I've written about NGC 346 in the past, but I couldn't leave out this new gem, recently released by Hubble, that gives us a unique ultraviolet view. Observations in ultraviolet light are useful because they help researchers understand more about star formation and evolution.

Do you love the moon? As part of NASA's International Observe the Moon Night, scientists from Reading Meteorology will bring telescopes out onto campus for young stargazers to be inspired by the wonders of the night sky. Limited tickets: rdg.ac/47dNBjq

Speaking of potentially hazardous objects, "2024 RW1" is only the 9th object detected on an incoming trajectory, allowing us to predict where/when it would slam into Earth's atmosphere. It hit today (Sept. 4) around 12:46 p.m. ET over the Pacific Ocean near the Philippines.
