The Incredible Expanding Crab. The #Crab #Nebula is cataloged as M1, the first on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, an expanding cloud of debris from the explosion of a massive star.

Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. Pictured above is the west end of the Veil Nebula known technically as NGC 6960 but less formally as the Witch's Broom Nebula. The expanding debris cloud gains its colors by sweeping up and exciting existing nearby gas.

LE LAC MORAINE : lac de montagne situé dans le Parc national de Banff dans la province de l'Alberta au #Canada. Il est situé à 14 kms du village de « Lac Louise ». Il s’étend sur un demi-kilomètre carré dans la « Ten Peaks Valley », à une altitude de 1 885 mètres. Le lac Moraine est ainsi nommé d'après les moraines (des débris de roches, cailloux, galets et sable) déposées par le glacier Wenkchemna, lors de sa fonte. Ce sont ces moraines qui donnent au lac sa couleur #turquoise. Merci B…

This supernova blast was so close, it littered the ocean floor with radioactive dust

A new star, likely the brightest supernova in recorded human history, lit up planet Earth's sky in the year 1006 AD. The expanding debris cloud from the stellar explosion, found in the southerly constellation of Lupus, still puts on a cosmic light show across the electromagnetic spectrum. In fact, this composite view includes X-ray data in blue from the Chandra Observatory, optical data in yellowish hues, and radio image data in red. Now known as the SN 1006 supernova remnant, the debris…
