SUBAURORALARC (STEVE) OVER THE ISLE OF LEWIS, SCOTLAND Taken by Giuseppe Petricca on March 18, 2018 @ Isle of Lewis, Eilean Siar, Scotland
A meeting with STEVE!
Last night, for the very first time for me, the phenomenon known as STEVE (Strong Thermal Emission Velocity Enhancement) appeared on the western skies, dancing for about half an hour in front of my eyes, on the left of the main aurora borealis arch.
An ever-changing tornado, with violet tones, always in movement, always with different shapes! There is not a picture when the details are the same compared to the previous or the next one! Another wonder of Nature!

Yesterdays unexpected Northern Lights storm was visible with the naked eye! Finally, lady Aurora visited Denmark since the beginning of November!
Taken with Canon EOS 6Da + Samyang 24mm f/1.4
Panorama of 15 shots @ 13 seconds, f/2, ISO 2500

A longer exposure a few minutes later revealed the Zodiacal Light.
CONJONCTION OF MERCURY, VENUS AND THE OLD MOON IN THE NEW MOONS ARMS Taken by David Joly on March 18, 2018 @ Saint-Didace, Québec, Canada
Venus was very bright in this perfect sky after sunset, side by side with Mercury and a crescent moon.
Details: Pentax K-01 with Pentax FA 77 mm lens, F/8, 3s exposure.

Comet C/2016 R2 (PANSTARRS) photographed on March 6, 2018 seems less active in spite of be still to two months of perihelion, although keeps its appearance with a small coma from which departs a blue narrow ionic tail that is opening in distance.

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from the death explosion of a massive star. This intriguing false-color image combines data from space-based observatories, Chandra, Hubble, and Spitzer, to explore the debris cloud in X-rays (blue-white), optical (purple), and infrared (pink) light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus.
This image captures a close-up view of a storm with bright cloud tops in the northern hemisphere of Jupiter.
NASA’s Juno spacecraft took this color-enhanced image on Feb. 7 at 5:38 a.m. PST (8:38 a.m. EST) during its 11th close flyby of the gas giant planet. At the time, the spacecraft was 7,578 miles (12,195 kilometers) from the tops of Jupiter’s clouds at 49.2 degrees north latitude.
Citizen scientist Matt Brealey processed the image using data from the JunoCam imager. Citizen scientist Gustavo B C then adjusted colors and embossed Matt Brealey's processing of this storm.
JunoCam's raw images are available for the public to peruse and process into image products at:

Seen as a seagull and a duck, these nebulae are not the only cosmic clouds to evoke images of flight. But both are winging their way across this broad celestial landscape, spanning almost 7 degrees across planet Earth's night sky toward the constellation Canis Major. The expansive Seagull (top center) is itself composed of two major cataloged emission nebulae. Brighter NGC 2327 forms the head with the more diffuse IC 2177 as the wings and body. Impressively, the Seagull's wingspan would correspond to about 250 light-years at the nebula's estimated distance of 3,800 light-years. At the lower right, the Duck appears much more compact and would span only about 50 light-years given its 15,000 light-year distance estimate. Blown by energetic winds from an extremely massive, hot star near its center, the Duck nebula is cataloged as NGC 2359. Of course, the Duck's thick body and winged appendages also lend it the slightly more dramatic popular moniker, Thor's Helmet.
