I stacked 62 raw frames from the Artemis II crew into one HDR picture: a total solar eclipse, seen from behind the Moon. Thank you Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen for shooting it, and NASA for releasing the raws this month. #ArtemisII #Astrophotography

Today I revisited my Carina Nebula from January (once again 😅). Still trying to find the look I like best, and still learning a lot about processing along the way.

A few close-ups: Eta Carinae and the Keyhole, NGC 3324, and some of the dusty clouds. (The spikes are added in processing.) Full size: stinga.jp/carina-2026/

A small remaining curvature in the timings fits the light-travel effect of a distant companion star, though the data can't yet prove it.

A 2024 study suggested that the hot Jupiter WASP-22 b was undergoing rapid orbital decay. At that rate, its 2026 transits should have arrived nearly 9 minutes ahead of schedule. Using new TESS data alongside re-timed 2018 data, I put this to the test.

Saturn from inside its shadow. On 13 April 2017 Cassini flew through Saturn's shadow: the Sun behind the planet, the rings glowing with light scattered through them, the night side lit only by the rings. More than 200 frames, rebuilt from the calibrated archive data at full resolution.

Data: NASA/JPL-Caltech/Space Science Institute. Thank you @carolynporco.bsky.social and the imaging team. @kevinmgill.bsky.social, same day as your Earth-and-Moon-through-the-rings view. @elakdawalla.bsky.social @philplait.bsky.social

The 12 Aug 2026 eclipse from space: the Moon covering the Sun as seen by ESA's Proba-3, joined with SOHO/LASCO and NASA's PUNCH in the same minutes, from the Moon's edge out to Venus. Distances compressed; catalogue stars; one gap filled. Details: www.flickr.com/photos/12467... #Proba3 #eclipse
