What's happening to these spiral galaxies? Although details remain uncertain, there sure seems to be a titanic battle going on. The upper galaxy is labelled UGC 1810 by itself, but together with its collisional partners is known as Arp 273 https://t.co/IZdk7nvND8
Can a lighthouse illuminate a galaxy? No, but in this image, gaps in light emanating from the Jose Ignacio Lighthouse in Uruguay appear to match up nicely, although only momentarily and coincidently, with dark dust lanes of our Milky Way Galaxy https://t.co/GdVQ8lOmo2
Have you ever seen a dragon in the sky? Although real flying dragons don't exist, a huge dragon-shaped aurora developed in the sky over Iceland earlier this month and was captured by Jingyi Zhang & Wang Zheng https://t.co/p96l7kccvO
The Flame Nebula stands out in this optical image of the dusty, crowded star forming regions toward Orion's belt, a mere 1,400 light-years away. Click on the link and explore it by swiping the cursor https://t.co/FjvmwxXbeW
A ghostly visage on a cosmic scale, these remains of shocked, glowing gas haunt planet Earth's sky toward the constellation of Cygnus and form the Veil Nebula, a large supernova remnant, an expanding cloud born of the death explosion of a massive star https://t.co/PeemC9KRtx
The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away https://t.co/9lSo0HaKXh
Why is there long red streak attached to this galaxy? The streak is made mostly of glowing hydrogen that has been systematically stripped away as the galaxy moved through the hot gas in a cluster of galaxies. The gas tail is about 200,000 light-years long https://t.co/lNoJRQ74iI
This image is a panorama of 38 images taken last month and compiled into a Little Planet projection by Anton Komlev. You can see the night sky, the Milky Way, the ruins of an abandoned outpost on a hill https://t.co/bYsnMFY1FB
Delicate in appearance, these filaments of shocked, glowing gas, are draped across planet Earth's sky toward the constellation of Cygnus. They form the western part of the Veil Nebula https://t.co/H6U2H7bgd4
The large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen https://t.co/YlWWQD1w0o
