I like astronomy, archaeology, photography, music and drinking a lot of tea. I hate politics. Something that annoys me: that I shall not respect the permanence, and to take me by what I'm not. The best sign: VIRGO. The worst: the health. The best: adapt and know how to get ahead.

ZEISS FULLDOME SHOW - THE GREAT UNDERSEA ADVENTURE OF BARNEY AND BEENIE
Now in ZEISS fulldome show distribution:
THE GREAT UNDERSEA ADVENTURE OF BARNEY AND BEENIE
This new planetarium show is a Fulldome Studio DN Original.
Interested planetariums can choose to purchase licenses with terms of one year, five years and fifty years.
Feel free to contact us by email at planetarium@zeiss.com!
This fun, educational and entertaining fulldome show for children is dedicated to the protection of the environment, the seas and the oceans.
Two friends, Barney and Beenie, take care of the cleanliness of their lagoon. Many adventures await them, one of which is the rescue of a small turtle stuck in a plastic net. And at night, friends learn the constellations.

COMET C/2023 P1 (NISHIMURA) NEAR NGC 2392 Taken by Georg Klingersberger on August 19, 2023 @ Kobernaußen Upper Austria
UT 02:23h FSQ 106mm F/3.6 EOS RP 6x60sec.ISO 1600 Such a joy, this comet surprise. You just have to get out of bed,into the wunderful night,chasing the comet!
COMET NISHIMURA VISITS ESKIMO NEBULA! Taken by Bill Williams on August 19, 2023 @ Chiefland Astro Village, Florida, USA
Read about newly discovered Comet Nishimura C/2023 P1 on Spaceweather.com. So I decided to take on the challenge of capturing it although my observatory roof slides east and usually precludes capturing low altitude pre-dawn objects. However, I was thrilled this morning when not only did Comet Nishimura show up but also the Eskimo Nebula just 18 arc minutes away in the same field!! I took 2-minute LRGB images (binned 3x3) to accelerate the capture since I was imaging after the beginning of astronomical twilight! I do not know what percentage of the 14.5-inch telescope aperture actually captured comet photons but it is safe to say much of the scope got a nice view of the roof gable! A thin ion tail also showed up! As well as distant galaxy PGC 21100! You don't know unless you try!
SUNSPOTS MAKE CLOUDS ON NEPTUNE
A new paper published Aug. 17th in the research journal Icarus offers dramatic proof that solar activity can affect planetary weather. The big surprise: That planet is Neptune, 2.5 billion miles from the sun. Twenty-six years of images taken by the Hubble Space Telescope show bright clouds forming in sync with the 11-year solar cycle:
The connection between Neptune and solar activity is surprising to planetary scientists because Neptune is our solar system's farthest major planet and receives only 0.1% of the sunlight Earth receives. Yet Neptune's cloudy weather seems to be driven by solar activity, and not the planet's four seasons, which each last approximately 40 years.
"This is extremely exciting and unexpected," says Erandi Chavez, a graduate student at Harvard-Smithsonian's Center for Astrophysics, who led the study when she was a student at UC Berkeley.
The research team confirmed Hubble's results using data from the Webb Space Telescope, the Keck Observatory, and the Lick Observatory. The link between sunspots and Neptune's clouds appears to be solar ultraviolet (UV) radiation, which peaks when sunspot counts are high.
"Our findings support the theory that the sun's UV rays, when strong enough, may be triggering a photochemical reaction that produces Neptune's clouds," says Imke de Pater, emeritus professor of astronomy at UC Berkeley and a senior co-author of the study.
Based on the data so far, it seems to take about two years for Neptune's clouds to fully form once the solar cycle reaches its peak. Solar Cycle 25 is rising now with a peak expected in 2024. This means Neptune's cloudy season is about to begin--a development amateur astronomers may be able to observe.

PERSEID METEOR HEADING UNDERNEATH POLARIS STAR Taken by Andrea Garcia on August 13, 2023 @ Frankfurt am Main, Germany
I left the camera outside during the night of August 13th and was pleased to see I catched a perseid meteor heading right underneath the polaris star. This image is taken with 50mm focal length, it is cropped.
DINOSAURS - A STORY OF SURVIVAL - ZEISS FULLDOME SHOW DISTRIBUTION
This planetarium show is a production of Render Area.
Interested planetariums can choose to purchase licenses with terms of one year, three years, five years and fifty years.
Feel free to contact us by email at planetarium@zeiss.com!
Like almost all children, Celeste is fascinated with dinosaurs. She is preparing a talk for her class about how they went extinct when Moon, a very wise and magical character, poses a tantalizing question: what if I told you that there are still dinosaurs among us?
Celeste will join Moon in a journey through time, and exciting adventure that will show them the Earth as it was in the very, very distant past.
They will see the fascinating transformations that these animals underwent over millions of years, creating giant creatures, armored beasts and super predators, until the day that a cataclysmic impact event caused a mass extinction on Earth.
But all is not lost. Celeste will discover the key to their survival.
