ZEISS INSTALLED A NEW FULLDOME VIDEO SYSTEM IN THE PLANETARIUM IN GRANADA, SPAIN.

In mid-July, ZEISS installed a new fulldome video system in the planetarium in Granada, Spain. The two ZEISS VELVET projectors replace an older fulldome system. The computer technology and software have also been completely renewed. The new technology ensures that the planetarium, which was built over 20 years ago, once again meets modern presentation standards and keeps pace with technological and scientific advances in astronomy. The VELVET projectors were developed by ZEISS to best meet the special requirements of astronomical dome projections.
In October last year, the European Space Agency (ESA) announced the opening of an office of the European Space Education Resource Office (ESERO) network, a programme providing educational resources to primary and secondary school teachers and students at the Science Park in Granada. Granada is thus the only Spanish city to have a European space office.
The Granada Science Park is an important attraction with 600,000 visitors a year near the city centre. Besides the planetarium, it includes many interactive exhibitions for families and school groups. Since its opening in 1995, the planetarium with a dome diameter of 10 m has been equipped with an upgraded ZEISS SKYMASTER ZKP 3/B planetarium projector, which continues to perform reliably.

Cerealia Facula, also known as the brightest spot on Ceres, is shown in this stunning mosaic close-up view. The high-resolution image data was recorded by the Dawn spacecraft, in a looping orbit, from altitudes as low as 34 kilometers (21 miles) above the dwarf planet's surface. Cerealia Facula is about 15 kilometers wide, found in the center of 90 kilometer diameter Occator crater. Like the other bright spots (faculae) scattered around Ceres, Cerealia Facula is not ice, but an exposed salty residue with a reflectivity like dirty snow. The residue is thought to be mostly sodium carbonate and ammonium chloride from a slushy brine within or below the dwarf planet's crust. Driven by advanced ion propulsion on an 11-year mission, Dawn explored main-belt asteriod Vesta before traveling on to Ceres. But sometime between this August and October, the interplanetary spacecraft is expected to finally run out of fuel for its hydrazine thrusters, with the subsequent loss of control of its orientation, losing power and the ability to communicate with Earth. Meanwhile Dawn will continue to explore Ceres in unprecedented detail, and ultimately retire in its orbit around the small world.

Apparently this comet now had second outburst and now has produced even quite long tail.

We stayed a few nights in the beautiful Warrumbungle National Park in NSW where the world famous Siding Spring Observatory is located. While camping in the park in a very cold -6 degrees, I managed to get some really lovely images of the night sky with just my camera and lenses on a tripod. The sky was just so amazingly beautiful, diamonds in the sky beautiful :-)

This image is of the South Celestial Pole above the trees, to the right of the image that trailing smudge is associated with the stars in the Milky Way where the Southern Cross (Crux) is going down to the west.

This is just a one image with an exposure time of 7314 seconds (2hours) which included another 2 hour in camera dark frame. I used a Canon 700D camera and a Sigma 10-20mm lens set at 11mm and f4.5, the ISO was 200.

The second outburst brightened the comet by 2m5 within three days. On the morning of July 17, he was already 8m0. A deep image showed a nearly 10 arc minute coma and a faint ion tail of more than half degree. After the first outburst, the comet was weak from 6 to 14 July.
Everything is possible now.

VENUS AND THE MOON Taken by Constantine Emmanouilidi on July 15, 2018 @ Drimonas mountain, Greece



Yesterday we had a magnificent view of the Moon and Venus conjunction in the evening sky. Me and Emelie were at the Greek National star party of amateur astronomers and while preparing for imaging a deep sky target, we had a pleasant surprise by the sky!

EGYPT UNCOVERS MUMMY BURIAL SITE NEAR GREAT PYRAMIDS

CAIRO (Reuters) - Egyptian archaeologists revealed on Saturday the details of an ancient burial shaft and a mummification workshop that were discovered 30 meters underground, near the Saqqara necropolis south of Cairo.




Archaeologists are hoping the mummification workshop will provide fresh insight into the chemical make-up of the oils used by ancient Egyptians to mummify their dead.

The burial shaft, which is over 2,000 years old, is believed to date back to the Saite-Persian period, approximately 664-404 BC. The shaft was originally discovered in April of this year containing 35 mummies in addition to stone sarcophagi.

"What this discovery will add are two very important things; the first is the type of oils used (in mummification), and their chemical make-up. So we will be able to identify the exact types of oils used," said Ramadan Badry Hussein, head of the Egyptian-German mission that uncovered the site.

Hundreds of small stone statues, jars, and vessels used in the mummification process were all found inside the burial chambers and excavated.

The most significant artifact was a gilded silver mask, the second only such discovery ever made, Minister of Antiquities Khaled al-Anany said.

"This object is very rare, to have a silver mask gilded with gold, and as Ramadan mentioned now, we have only two of this kind, so it is a very nice discovery," al-Anany told Reuters.

Archaeologists have so far this year excavated a number of relics that include a 4,400-year-old tomb at the Giza plateau and an ancient necropolis in Minya, south of Cairo.

Egypt is hoping these discoveries will brighten its image abroad and revive interest among travelers who once flocked to its iconic pharaonic temples and pyramids but who have shunned the country since its 2011 political uprising.

RINGS AROUND THE RING NEBULA Image Credit: Hubble, Large Binocular Telescope, Subaru Telescope; Composition & Copyright: Robert Gendler






Explanation: There is much more to the familiar Ring Nebula (M57), however, than can be seen through a small telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star. This remarkable composite image includes narrowband hydrogen image, visible light emission, and infrared light emission. Of course, in this well-studied example of a planetary nebula, the glowing material does not come from planets. Instead, the gaseous shroud represents outer layers expelled from a dying, sun-like star. The Ring Nebula is about 2,000 light-years away toward the musical constellation Lyra.

" ESTRELLA VEGA " DESDE ROSARIO - ARGENTINA //// FOTOS: ESMERALDA SOSA - INFO: LICENCIADO EN FÍSICA: JOSÉ LUIS LOMÁSCOLO




Estrella VEGA desde Rosario - Argentina /// 09-07-2018 1am





Lira puede verse sobre la derecha en Mapa Estelar de 1825 de " Urania's Mirror ".



Vega la estrella más brillante de la constelación de la Lira se sitúa a unos 25 años luz de la Tierra.



Hace 14000 años, cuando  todavía caminaban  sobre este  planeta el Mamut, el Megaterio, el Gliptodonte, el Smilodon, cuando hacía más de  3000 años que en la cueva de Lascaux, llamada la capilla Sixtina del arte  prehistórico, desconocidos artistas habían  plasmado sobre sus paredes y techo figuras de ciervos, caballos, bisontes y toros, Vega no era visible desde la posición geográfica que hoy ocupa la ciudad de Rosario.




Imagen de una sección de la cueva de Lascaux.




Por entonces, esta estrella se encontraba a  3° 41' del polo norte celeste, pudiendo ser calificada en ese momento como estrella polar, denominación que hoy ostenta Polaris, la estrella más brillante de la constelación de la Osa Menor.


Vega volverá a convertirse en la estrella polar en unos 11 720 años.


El responsable de este fenómeno es la precesión de los equinoccios, un lento movimiento del eje de rotación de la Tierra provocado por las fuerzas que ejercen la Luna y el Sol sobre el abultamiento ecuatorial de esta ( el eje de rotación de la Tierra realiza un giro completo en unos 25 776 años ).





El eje de la Tierra está sometido a un movimiento de precesión similar al que se puede observar en un trompo.





Proyección del movimiento del eje de rotación de la Tierra sobre la esfera celeste, +2000 indica el año 2000, con Polaris como la estrella polar, +14000 indica el año 14000, con Vega muy próxima a lo que en ese momento será el polo norte celeste ( Vega está representada por el círculo blanco de gran tamaño que se puede observar en la parte inferior de la imagen ).
