The Orion #Nebula in Visible and #Infrared

The Orion Nebula, visible to the naked eye, is a vibrant mix of young stars, hot gas, and dust. This image combines visible and infrared light from Spitzer #Telescope, revealing shock waves and the Trapezium's bright stars. Spanning 40 light-years, it's 1500 light-years away in our #Galaxy's spiral arm.

Milchstrasse
Aussichtspunkt Niesenbänkli in Ringoldswil um 4 Uhr morgens. Es war kalt und ich habe 2-3 Stunden an der gleichen Stelle die Milchstrasse fotografiert, wunderte mich, dass die Sicht durch die Kamera immer trüber wurde, bis ich feststellte, dass sich Raureif auf der Linse gebildet hatte.

Virgo Cluster Galaxies

This telescopic view captures the Virgo Cluster, 50 million light-years away, featuring bright elliptical galaxies M87, M86, and M84. M87 dominates with its supermassive black hole, first imaged by #Earth's Event Horizon #Telescope. Markarian's Chain is visible, including the interacting galaxies NGC 4438 and NGC 4435.

NGC 4449: Star Stream for a Dwarf #Galaxy

NGC 4449, a dwarf galaxy 12.5 million light-years away in Canes Venatici, is actively forming stars. Comparable to the Large Magellanic Cloud, it has blue star clusters and dust clouds. It features a tidal star stream from a merging satellite galaxy, hinting at dark matter's role in galactic mergers and evolution.
