Latest STScI News Release

NASA's Hubble, Webb Probe Surprisingly Smooth Disk Around Vega

The top-left half of the image is a Hubble Space Telescope view of a 100-billion-mile-wide disk of dust around the summer star Vega. The disk is represented in blue. The color trails to white as we get closer to the center of the disk. The black spot at the center blocks out the bright glow of the hot young star. The disk is perfectly circular because we are looking down on top of it. The lower-right half of the image is a view from the James Webb Space Telescope, which reveals the glow of warm dust in the disk's halo that is colored orange. The disk is brighter toward the center. There is a notable dip in surface brightness between the inner and outer disk.

Webb and Hubble examine spooky galaxy pair

Galaxies IC 2163 and NGC 2207 (Webb and Hubble image)

31 October 2024

Stare deeply at these galaxies. They appear as if blood is pumping through the top of a flesh-free face. The long, ghastly ‘stare’ of their searing eye-like cores shines out into the supreme cosmic darkness.

JWST Picture of the Month

Catching the edge of the Phantom Galaxy

https://cdn.esawebb.org/archives/images/thumb350x/potm2410a.jpg

29 October 2024
In August 2022, to mark the launch of the Picture of the Month series, ESA/Webb published a stunning image of the Phantom Galaxy (also known as M74 and NGC 628). Now, this series is revisiting the target to feature new data on this iconic spiral galaxy. M74 resides around 32 million light-years away from Earth in the constellation Pisces, and lies almost face-on to Earth. This, coupled with its well-defined spiral arms, makes it a favourite target for astronomers studying the origin and structure of galactic spirals. This image features data from two of Webb’s instruments: MIRI (Mid-InfraRed Instrument) and NIRCam (Near-InfraRed Camera). Observations in the infrared reveal the galaxy’s creeping tendrils of gas, dust and stars. In this image the dark red regions trace the filamentary warm dust permeating the galaxy. The red regions show the reprocessed light from complex molecules forming on dust grains, while orange and yellow …

NASA Image of the Day

X-59’s Engine Started for Testing

NASA’s X-59 quiet supersonic research aircraft sits in its run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California, firing up its engine for the first time. These engine-run tests start at low power and allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.

Distance: 268 light-years, Magnitude: 2.65

A star designated ALPHA in the constellation Corvus. The name is Arabic for "collared dove".

Star Chart | DSS IR Image 🔗

 

Archid A (eta Cassiopeiae A ) in Cassiopeia

Distance: 19 light-years, Magnitude: 3.4

Eta Cassiopeiae (Archid or GJ 34) is a spectroscopic binary pair in a 480 years orbit (eccentricity 0.5) at a mean distance of 71 (36 to 106) AU. The primary is a sun-like star, 97% the mass and 1.04 times the solar radius with a low projected rotational velocity of 3.15 km/s. The companion, B, has 57% the mass of the sun and measures 0.66 solar radii.

M25 (Open Cluster) in Sagittarius

Magnitude: 14.5

Cruising along about 2,060 light-years away, M25 spans about 19 light-years across. Caught inside of its influence are four giant stars - two of spectral type M and two of type G. It contains the variable star U Sagittarii, a Delta Cephei-type, which lets us know this group of 86 or so stars may have began life together 90 million years ago.

Ophiuchus (southern), area rank: 11

Displaying the shape of a large pentagon, this constellation is situated south of Hercules. The name of the 2nd-magnitude star, Rasalhague, is Arabic for "the head of the serpent-charmer". The figure represents the Greek healer Asclepius.

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.

 

 

Hektor (Asteroid)

Semi-major: 5.22753 AU, Size: 370 km

Discovered on February 10 1907 by August Kopff, Hektor is the largest Jupiter trojan and a D-type asteroid, dark and reddish in colour. Hektor is one of the most elongated bodies of its size in the Solar System, being 370 x 200 km. On July 17th 2006, a 12-km-diameter moon of Hektor, S/2006 (624) 1, was detected with an orbit semi-major axis of 623.5 km and an orbit period of 2.9651 days. Hektor is the first known trojan with a satellite companion. Rotating once around its axis in 6.92 hours, the asteroid has a mean mass of 9.95x1018kg and a density of 1.63g/cm³.

 

 

Triton (moon of Neptune)

Discovered in 1846, Triton is Neptune's largest moon in a retrograde orbit. Triton has a sparsely cratered surface with smooth volcanic plains, mounds and round pits formed by icy lava flows. Triton's thin atmosphere is composed mainly of nitrogen with small amounts of methane.

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.
