30 Doradus, located in the heart of the Tarantula nebula, is the brightest star-forming region in our galactic neighborhood. The nebula resides 170,000 light-years away in the Large Magellanic Cloud. Links to very large images in comments.
After chasing it for more than two years I was finally rewarded with two displays of Aurora Australis (Southern lights) within a week visible from Mornington peninsula, not far from Melbourne. The nights were warm an clear and the Moon was not in the sky either - I could not have asked for better conditions. The red color of this aurora is caused by the charged particles from the Sun exciting oxygen atoms high in the Earth’s atmosphere. … Being able to photograph it all night I came up with a nice video. The brighter Aurora happened on January 22nd and the smaller one, featured in the middle section, was from January 16th, followed by a rather bright Moonrise.
I never like videos that boomerang but still had to share this one - stars rotating over a dead, undecomposed tree in Sossusvlei, Namibia - you can clearly make out the large and small Magellanic Clouds - two minor galaxies close to the Milky Way.
Why would the sky glow red? An aurora! A solar storm in 2012, mostly coming from an active sunspot, showered particles on the Earth that excited oxygen atoms high in the Earth’s atmosphere. As the excited element’s electrons fell back to their ground state, they emitted a red glow.
The sky that night, however, also glowed with more familiar but more distant objects, including the central disk of our Milky Way Galaxy on the left, and the neighboring Large and Small Magellanic Cloud galaxies on the right.

Here’s the labelled image for anyone who is interested:
When a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way, it left behind an expanding shell of debris called SNR 0519-69.0. Here, multimillion degree gas is seen in X-rays from Chandra (blue). The outer edge of the explosion (red) and stars in the field of view are seen in visible light from Hubble.
In parts of Antarctica, not only is it winter, but the Sun can spend weeks below the horizon.At China's Zhongshan Station, people sometimes venture out into the cold to photograph a spectacular night sky.The featured image from one such outing was taken in mid-July, just before the end of this polar night.Pointing up, the wide angle lens captured not only the ground at the bottom, but at the top as well. In the foreground is a colleague also taking pictures.In the distance, a spherical satellite receiver and several windmills are visible.Numerous stars dot the night sky, including Sirius and Canopus.Far in the background, stretching overhead from horizon to horizon, is the central band of our Milky Way Galaxy.Even further in the distance, visible as extended smudges near the top, are the Large and Small Magellanic Clouds, satellite galaxies near our huge Milky Way Galaxy.
This delicate shell, photographed by the NASA/ESA Hubble Space Telescope, appears to float serenely in the depths of space, but this apparent calm hides an inner turmoil. The gaseous envelope formed as the expanding blast wave and ejected material from a supernova tore through the nearby interstellar medium. Called SNR B0509-67.5 (or SNR 0509 for short), the bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud (LMC), a small galaxy about 160 000 light-years from Earth. Ripples in the shell’s surface may be caused either by subtle variations in the density of the ambient interstellar gas, or possibly be driven from the interior by fragments from the initial explosion. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 18 million km/h.
Hubble’s Advanced Camera for Surveys observed the supernova remnant on 28 October 2006 with a filter that isolates light from the glowing hydrogen seen in the expanding shell. These observations were then combined with visible-light images of the surrounding star field that were imaged with Hubble’s Wide Field Camera 3 on 4 November 2010.
