JWST Picture of the Month

The exotic stellar population of Westerlund 1

https://cdn.esawebb.org/archives/images/thumb350x/potm2409a.jpg

4 October 2024
The open cluster Westerlund 1, showcased in this new Webb Picture of the Month, is located roughly 12 000 light-years away in the southern constellation Ara (the Altar) where it resides behind a huge interstellar cloud of gas and dust. It was discovered in 1961 from Australia by Swedish astronomer Bengt Westerlund. Westerlund 1 is an incomparable natural laboratory for the study of extreme stellar physics, helping astronomers to find out how the most massive stars in our Galaxy live and die. The unique draw of Westerlund 1 is its large, dense, and diverse population of massive stars, which has no counterpart in other known Milky Way galaxy clusters in terms of the number of stars and the richness of spectral types and evolutionary phases. All stars identified in this cluster are evolved and very massive, spanning the full range of stellar classifications including Wolf-Rayet stars, OB supergiants, yellow hypergiants …

Imagining the Future

An unidentified illustration of NASA's space shuttle. The space shuttle fleet flew 135 missions and helped construct the International Space Station between the first launch on April 12, 1981 and the final landing on July 21, 2011. There were five orbiters: Columbia, Challenger, Discovery, Atlantis and Endeavour.

Random Objects

 

Rana (23 Del Eri) in Eri [HIP 17378]

Distance: 29 light-years, Magnitude: 3.54

Delta (23) Eridani, or Rana, Latin for frog, is just under 30 light-years away in Eridanus. Being 3 times more luminous and measuring 2.327 times the radius of the sun, Rana is a subgiant with 1.33 solar masses which has almost depleted its hydrogen, now consuming helium as it expands. The star rotates slowly at 1 km/s.

GJ 273 (Luyten's Star) in Canis Minor

Distance: 12 light-years, Magnitude: 9.8

Named after Dutch-American astronomer Willem Jacob Luyten, who measured its proper motion, red-orange hued Luyten's Star is a red dwarf, a third the size and a quarter the mass of the Sun. Luyten's star is a slow rotater but moves across the sky at a rate of 3.74 arc seconds per year. It came as close as 11.8 light-years some 13,000 years ago. Its curent distance to its next neighbor Procyon is 1.2 light-years.

M87 (Galaxy) in Virgo

Magnitude: 9.6

Stretching across 120,000 light-years, M87 has much more stars than our Milky Way galaxy, and is extremely luminous as it contains a remarkable system of several thousands globular clusters.

Pictor (southern), area rank: 59

Invented in the 18th century by astronomer Louis de Lacaille. Located southwest of Canopus in Carina, the constellation can be seen at 25 degrees northern latitude in the south over the horizon. It resembles a canvas on a tripod with a paint palette.

19P/Borrelly

Discovered in 1904, the elongated 8km wide 19P/Borelly is a short-period comet orbiting the sun in 6.8 years. On September 2001, NASA's Deep Space 1 probe visited Borelly during an extended mission and sent back detailed images of the surface.

 

 

1994 CC (NEO)

Semi-major: 1.63761 AU, Size: 0.7 km

Radar imaging at NASA's Goldstone Solar System Radar on June 12 and 14, 2009, revealed that near-Earth asteroid 1994 CC is a triple system. Asteroid 1994 CC encountered Earth within 2.52 million kilometers on June 10. Prior to the flyby, very little was known about this celestial body. 1994 CC is only the second triple system known in the near-Earth population. 1994 CC consists of a central object about 700 meters in diameter that has two smaller moons revolving around it. Preliminary analysis suggests that the two small satellites are at least 50 meters in diameter.

 

 

Ganymede (moon of Jupiter)

Discovered in 1610 by G. Galileo, Ganymede is the third and largest of Jupiter's 'Galilean Satellites', and the largest known moon in the solar system with 0.413 Earth radii. Ganymede is composed of equal amounts of silicate rock and water ice under which a saltwater ocean is believed to exist about 200 km below. Its surface is composed of old impact craters and regions of grooves and ridges with tidally forced tectonic activity. Ganymede is the only moon known to have a magnetossphere. March 2015: NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface. Hubble was used to watch aurorae glowing above the moon's icy surface. The aurorae are tied to the moon's magnetic field, which descends right down to the core of Ganymede. A saline ocean would influence the dynamics of the magnetic field as it interacts with Jupiter's own immense magnetic field, which engulfs Ganymede.

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.
