Hubble Spots a Magnificent Barred Galaxy

The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across.

Pectus (35 Lam Tau) in Tau [HIP 18724]

Distance: 370 light-years, Magnitude: 3.41

Lambda Tauri, or Pectus Tauri (Latin for the bull's chest) is a triple star system. Lambda Tauri AB orbit around each other with a period of 3.95 days at a distance of 0.1AU. Since B eclipses A, their combined brightness changes between 3.37 and 3.91 magnitudes. A third component, C, is orbiting the inner pair every 33 days. With its 50% solar mass C alters the orbit of the inner pair.

WISE 0855-0714 (Luhman 18) in Hydra

Distance: 7 light-years, Magnitude: 16.2

WISE 0855-0714 is a (sub-)brown dwarf 7.175 light-years from Earth announced in 2014 by Kevin Luhman using data from the Wide-field Infrared Survey Explorer (WISE). It has the third highest proper motion and the fourth largest parallax of any known star or brown dwarf. It is also the coldest known brown dwarf with an estimated effective temperature of 225 to 260°K and a mass of 3 to 10 that of Jupiter. This mass is in the range of a sub-brown dwarf or other planetary mass object. Any planets that might orbit it would be much too cold to support life as we know it. It was discovered in March 2013 through its rapid motion across the sky in two infrared images the WISE satellite taken six months apart (for parallax measurement) in 2010. As seen from WISE 0855-0714, the sun shines at magnitude 1.54 in Delphinus alongside nearby Altair which shines at 1.46 magnitudes 23.7ly away from WISE 0855-0174.

M71 (Globular Cluster) in Sagitta

Magnitude: 8.2

M71 is a loosely concentrated globular cluster at a distance of about 13,000 light-years and spans some 27 light-years across. The irregular variable star Z Sagittae is a member of this cluster.

Canis Major (southern), area rank: 43

Canis Major's mark is the brightest star in the night sky, Sirius. In the constellation picture, Sirius represents the mouth of the "dog". The star connecting constellation lines allow easy recognition of the dog-shape. South of Sirius is the star cluster M41, beautiful to see in binoculars. The five brightest stars are printed on the flag of Brazil to represent 5 of its 27 states.

81P/Wild 2 (2013)

Discovered in 1978, 81P/Wild or Wild 2 is 5.5km wide short-periodic comet with an orbit period of 6.41 years originating from beyond Pluto. In September 1974, the comet passed within one million kilometers of the planet Jupiter, as it's orbital period changed from 43 years to current 6.41 years due to Jupiter's strong gravitational pull. NASA's Stardust mission reached Wild on January 2, 2004, collecting particles from its coma (including organic compounds) and sent back detailed surface images of the nucleus.

 

 

Ryugu (Asteroid)

Semi-major: 1.18965 AU, Size: 0.914 km

Discovered on May 10, 1999 by the LINEAR project, Ryugu, formerly 1999 JU3, is a C-type Apollo asteroid, a rocky body expected to contain notable organic matter and water in its rocks. Its mean distance to the sun is 1.1895AU resulting in an orbital period of 1.3 years. It is therefore classified as near-Earth object (NEO) and potentially hazardous asteroid (PHA) of the Apollo group. Ryugu is approximately 1km in diameter (polar radius 440m) and has a mass of 450 million tons. It takes Ryugu about 7.627 hours to spin retrograde once around its axis. Due to 'seasons' the surface temperature varies between 30 and 100°C. Japan's Hayabusa 2 is designed to study asteroid Ryugu from multiple angles, using remote-sensing instruments, a lander and a rover. It will collect a surface, and possible subsurfaces materials from and return the samples to Earth in a capsule for analysis by December 2020.

 

 

Weywot (moon of Quaoar)

Weywot is the only known moon detected in 2005 around the trans-Neptunian object Quaoar and likely to be a collisional fragment of Quaoar.

Dark Site in Morocco

Some say that the seeing is better only in space.

Click on the banner to visit the new website of SaharaSky, the first and currently only private observatory with Casbah-style *** hotel in North Africa.

 

The owner, Fritz, is a German with a life-long passion for astronomy. Then, as he felt in deep love with Morocco and its wonderful people, he built a self-contained hotel at the feet of the Sahara about 30 kilometers to the southeast of the town of Zagora entirely in the traditional southern Moroccan Casbah-style and equipped it, besides comfortable rooms, a restaurant, spa and sauna, with a rich portfolio of optical instruments and accessories for amateur astronomers.

Fritz chose the location extremely well, a truly dark site in absence of city and street lights, blessed with an average of 300 clear dry nights annually. The observatory atop the hotel building offers a 360 degrees panoramic view on 500 square meters.

Most guests are professional and amateur astronomers, but also people of all ages with affection for the fascination of the stars and the desert. From the hotel's wide roof terrace, everybody can enjoy the starry sky dominated by the arch of the Milky Way with bare eyes or with rental telescopes and cameras.

The heart and soul of SaharaSky's observatory is Patrick from Belgium, not only a senior professional astronomer, but also a talented animator and entertainer under the Saharan stars.

A stay at SaharaSky is not limited to the night sky. SaharaSky provides equipment for solar observation, but Fritz also organises desert excursions for several days, overnight or day-return treks in a 4x4 or on dromedar backs, plus guided tours to historically invaluable local sites, such as the Petroglyphs of Ait Ouazzik.

Owner and staff as a team speak Arabic, local Berber, English, French, German, Spanish and Dutch.

Scotty, lock on to the coordinates of SaharaSky and beam us over!


SaharaSky owns telescopes with apertures from 40 to 400mm, such as Takahashi APOs, each of which can be saddled on high precision GM2000 mounts featuring GPS, GoTo and accurate guiding for both, visual observation and photography.
