LL ORI AND THE ORION NEBULA Image Credit: NASA, ESA, and The Hubble Heritage Team

Stars can make waves in the Orion Nebula's sea of gas and dust. This esthetic close-up of cosmic clouds and stellar winds features LL Orionis, interacting with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged Sun. As the fast stellar wind runs into slow moving gas a shock front is formed, analogous to the bow wave of a boat moving through water or a plane traveling at supersonic speed. The small, arcing, graceful structure just above and left of center is LL Ori's cosmic bow shock, measuring about half a light-year across. The slower gas is flowing away from the Orion Nebula's hot central star cluster, the Trapezium, located off the upper left corner of the picture. In three dimensions, LL Ori's wrap-around shock front is shaped like a bowl that appears brightest when viewed along the "bottom" edge. This beautiful painting-like photograph is part of a large mosaic view of the complex stellar nursery in Orion, filled with a myriad of fluid shapes associated with star formation.

Yesterday moon 3% illuminated with beautiful earth shine and an airplane landing in Brasilia.

ZODIACAL LIGHT Taken by Noel Keating on February 17, 2018 @ Rossnowlagh Beach , Co Donegal , Ireland

Its that time of year again to witness the Zodiacal Light and Yesterday I rushed down the beach to capture it. I was a little later than I planned to be but it was still very vivid and easily spotted to the west. I love watching this light and although it doesnt actually do everything spectacular compare to Auroras or Noctilucent clouds, it still a beautiful sight in the night sky and to think you are seeing a beam of sunlight shining through space, well that is awesome..
