I stopped posting satellite pics because those putin-lovin' moderation fuckers suspended my account. Again. It was the 4th time. Enough is enough.

Dark Shrouds in Orion Shadowy clouds of LDN 1622 are pictured in this observ from Nicholas U. Mayall 4m🔭at Kitt Peak National Observ. Image captured in 2018 by Mosaic-3 instrument, wide-field 📸 used to capture large swaths of night sky from Kitt Peak in Arizona noirlab.edu/public/image...

Mosaic-3 has since been retired to make way for the Dark Energy Spectroscopic Instrument
(DESI), the most powerful multi-object survey spectrograph in the world. This swap highlights one of the benefits of ground-based astronomy: the ability to upgrade and replace instruments as new technologies become available.

LDN 1622 is a dark nebula, so called because these dense interstellar clouds of gas and dust blot out light from background objects, appearing as ink-dark clouds against a backdrop of stars. This enigmatic cosmic cloud lies 1300 light-years from Earth in the nearby Orion complex, a star-forming region thronging with young stars and other dark nebulae.

This observation was taken before the 2022 Contreras Fire, which affected KPNO.

A large, snaking coronal hole is directly facing Earth now. Effects are already being felt at Earth with Bt > 15 nT - pretty enhanced! Mid-latitude auroral displays are possible tonight, especially strong during substorms. Coronal hole influences may persist for a few more days.

This is a real timelapse video of the Moon transiting in front of the Earth. It was captured by the Artemis 1 Orion spacecraft in November 2022 while flying at it's furthest point from the Earth. The video covers about 3.75 hours of real time. 🔭🧪

Ongoing eruption of Piton de la Fournaise volcano in Reunion Island. Lava flow is ~3.5 km long 📏😊 Image taken today by Sentinel-2.

Multiple C flares erupt across large sunspot which sent out massive X flare few days ago 5h time lapse sped up several times. In certain situations, features can actually move fast enough to be observed real time,in a more practical sense,hydrogen plasma moving much faster than we think. 📸simon2940
