Distant interacting galaxies – located 23 million light-years away – bear an uncanny resemblance to a penguin guarding an egg. The “penguin” part of the pair was probably once a relatively normal-looking spiral galaxy, flattened like a pancake with smoothly symmetric spiral arms. Rich with newly-formed hot stars, seen in visible light as bluish filaments, its shape has now been twisted and distorted as it responds to the gravitational tugs of its neighbor. The “egg” of the pair is distinctly different with its greenish glow, which tells the story of a population of much older stars. The absence of glowing red dust features informs us that it has long since lost its reservoir of gas and dust from which new stars can form. Eventually these two galaxies will merge to form a single object, with their two populations of stars, gas and dust intermingling. This kind of merger was likely a significant step in the history of most large galaxies we see around us in the nearby universe, including our own Milky Way. Data from our Spitzer and Hubble (@NASAHubble) space telescopes have been combined to show these dramatic galaxies in light that spans the visible and infrared parts of the spectrum.

Went to see the Tonic eye wear at the show. Fishermen love the polorised glass lenses. I like them because they make everything look like a David Lean movie.
Just saw this!
Imagine a Europe invaded by a million solders and artillery and bombs dropping from the sky killing thousands per nightly raid. Replaced now by barrages of media coverage and an onslaught of hysteria. The people who were killed and their loved ones, and the trauma of the event is nothing short of tragic. But it isn’t a world at war taking a 100 million lives in four years. Chin up.
Never give in, never ever surrender. Winton Churchill. Viva La France. Long live freedom.
