Trails Of Lights And Fires On Mount Etna 2 - Unesco World Heritage Site
dariogiannobile.com
Copyright: Dario Giannobile
Sicily - March 2017, The Volcano Etna woke for the second time in a month.
According to Greek mythology, Hephaestus was the craftsman and smith of gods.
The ancient Greeks and Sicilians believed that he had his abode and his forge under the volcano Etna and that the eruptions were the proof of his mighty work.
From ct.ingv.it: "On the morning of 15 March 2017, a new eruptive episode started at Etna's Southeast Crater. The eruptive vent was located in the area of the former "saddle" between the southeast Crater (SEC) and the New Southeast Crater (NSEC). In the early morning hours of 15 March, a small lava flow started oozing down the south flank of the SEC-NSEC cone complex. Then the eruptive activity rapidly intensified with nearly constant Strombolian explosions that generated amounts of volcanic ash dispersed in the atmosphere. The lava flow had reached the base of the cone and was slowly expanding on the gently sloping terrain toward south.”
The landscape was enlightened by the gentle light of the Moon showing the “Sciara”, the black volcanic, rocks covered by a thick layer of snow.
From the top crater a fountain of lava left traces on the sky in front of a curtain of gentle lights pictured by the stars rotating around Polaris.

After publishing the image I discovered that small earthquakes were recorded in the picture as a consequence of the Strombolian activity!
Here is a detail that shows the volcanic tremor as can be seen in the star trails that appear not regular and smooth!!!

The constellation of Orion is full op splendour. Here we can see a river of ionised hydrogen atoms streaming from the top left to the lower right corner of the image. It is part of Barnard's Loop. In this composition, Barnard's Loop crosses between M78 (in the lower left) and LDN 1622, also know as the "Boogie Man Nebula".

M88. Copyright KG Observatory.
Charles Messier described the 88th entry in his 18th century catalog of Nebulae and Star Clusters as a spiral nebula without stars. Of course the gorgeous M88 is now understood to be a galaxy full of stars, gas, and dust, not unlike our own Milky Way. In fact, M88 is one of the brightest galaxies in the Virgo Galaxy Cluster some 50 million light-years away. The arms are lined with young blue star clusters, pink star-forming regions, and obscuring dust lanes extending from a yellowish core dominated by an older population of stars. Spiral galaxy M88 spans over 100,000 light-years.

Powerfull aurora borealis display in Denmark
Credits: Adrien Mauduit
We have been waiting over 4 months to see a display like that! And the wait is finally over, it's not so easy to be at the bottom of the hill in the sun's cycle. The NOAA promised a G1 storm watch for last night, and we got a good show from 8:00pm til 10:00pm but Lady aurora was hardly visible through the fast moving storm cells and showers!! Then around 11:00pm it snowed for an hour, so I went back home and I thought my night was over. As I look back at the magnetometer before going to bed, it's going crazy again and the rain had let up, clearing up! I hurried back to the point I was shooting at and got in just in time to capture these magnificent green and pink pillars (G2 storm)! The marvelous show lasted only minutes, but it was well worth going back!

Milky way core reflecting onto the still Baltic

It is really to get a clean shot of the milky way in Denmark, as the main island is constantly battered by sea mist, salty winds and haze. Two nights ago was the perfect night to get the perfect rare shot at the rising milky way core over the silent and still waters of the Baltic sea, mirroring our galaxy

After a very rainy winter in Lofoten, I am heading for one month to my home country, Romania.
Last night, while flying from Bodø to Oslo I was expecting to see some Aurora activity, given the forecast. So, the moment we took off, my eyes got stuck to the window. For about 3/4 of the flight, beautiful Northern Lights danced on both sides of the plane. Big thank you to the crew of SAS flight SK4127 for turning off the cabin lights. Really beautiful show.

Solar storm under the Danish milky way
Credits: Adrien Mauduit
The on-going solar storm was bright and powerful enough to be seen from Denmark, where it put on a magical show before the clouds rolled in on March 27th 2017. The picture is taken on Høve strand in Denmark over the calm shores of the Baltic sea, reflecting the aurorae. The nice arc of the winter milky way (orion, California nebula, Rosette nebula) is disappearing towards the north to give its place to the spring milky way that will appear above the south-eastern horizon hours later.
