Hubble Solves Merger Mystery From Milky Way’s Early Years

An illustration of two galaxies in the midst of a collision against a dark, star-filled background. The collision takes up the middle third of the illustration. On the right, a larger galaxy is viewed at an angle from 11 o’clock to 4 o’clock, with a white-yellow core surrounded by mottled brown dust lanes and faint bluish spiral arms. To the left, a smaller, bright blue-white galaxy is stretched into a curved, hook-like shape as gravity distorts it. A broad, glowing bridge of pale blue gas and stars extends off the galaxy at the left, while wispy streams extend above and below the larger galaxy at the right. The words “Artist’s Concept” appear in the lower left corner.

Webb reveals dust and water surviving in the extreme environment around the Milky Way’s central black hole

IRS 3 Field (NIRCam and MIRI image)

11 August 2026

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the centre of our Milky Way galaxy. The observations reveal that the evolved star IRS 3 continues to enrich its surroundings with newly formed material despite the intense radiation environment around Sagittarius A*.

JWST Picture of the Month

Striking star clusters and irregular clumps

https://cdn.esawebb.org/archives/images/thumb350x/potm2608a.jpg

27 August 2026
The latest ESA/Webb Picture of the Month is a new, infrared look into the strange final phase of a galactic merger. Arp 263, an irregular galaxy, lies in the constellation Leo at a relatively nearby distance of around 25 million light-years. Originally discovered in 1784 and also catalogued as NGC 3239, this galaxy was included in American astronomer Halton Arp’s Atlas of Peculiar Galaxies in 1966, as possibly one of the most remarkable and strange galaxies in the sample. Arp categorised it with the galaxies featuring “irregular clumps”. In 2023, the galaxy was featured in an image from the NASA/ESA Hubble Space Telescope, where these clumps are revealed to be bright nebulae between the galaxy’s dense clouds of gas, where stars are forming. Arp 263 is believed to result from a past galactic merger. Apart from its unusual distorted shape, astronomers have noticed a few features that point to this. …

1. This web site is target of "Distributed Denial of Service (DDoS)" attack intended by criminals to exhaust the resources of a hosting server. It is a high frequency random access to all web files in the site directory, a classic tactic, aiming to degrade or crash hosting infrastructure. This website is the entry point, but the real goal is to overwhelm the web server or shared hosting environment. Most of the attacking IP addresses originate in the PRC, either on purpose to blame China or it is real. My provider, Hostgator, does not seem to be interested in deeper investigation, instead suggesting the service of "Cloudflare". Even if the contents of the site isn't sensitive, the attack is criminal calling for harsh punishment. This attack also falsifies the visitor access log, wondering what this human garbage is trying to accomplish besides display of sick brains.

2. Certain people appear to enjoy filling forms with random letters for no purpose but insane self-satisfaction. Most of this stupid folks leave their IP addresses which are forwarded to their provider companies. All so received forms are automatically deleted. Sadly, the world is overfilled with idiots, trolls and criminals. This is a public web site without any sensitive data. No need for these irrational displays.

3. Now in the process of changing all large images to AVIF or WEBP format resulting in considerably reduced file size and download time hardly sacrificing quality as compared with JPEG.

Alhakim (Iot Cen) in Cen [HIP 65109]

Distance: 59 light-years, Magnitude: 2.75

Alhakim, Arabic for 'the wise one' is a white hued star 2.5x more massive and 26x more luminous than the Sun, and is roughly 350 million years old. It rotates at 90.3 km/s and is surrounded by an unusually luminous circumstellar debris disk extending 6 AUs.

GJ 832 (LHS 3865) in Grus

Distance: 16 light-years, Magnitude: 8.6

Gliese 832 is a red dwarf 16.14 light-years away in the constellation Grus and has about half the mass and radius of the Sun. Gliese 832 is home to 2 known planets, the innermost (c) orbiting within the star's habitable zone - the closest potentially habitable Earth-mass range exoplanet to our solar system.

M61 (Galaxy) in Virgo

Magnitude: 10.1

Spanning about 100,000 light-years across and about the same size as our own Milky Way Galaxy, this grand old spiral is one of the largest in the Virgo Cluster, and one of the most active in terms of starbursts and supernovae.

Mensa (southern), area rank: 75

Created by astronomer Louis de Lacaille in the 18th century, this constellation cannot be seen in the northern hemisphere. It is the faintest constellation in the entire sky. The "Table Mountain" south of Cape Town at the southern tip of Africa is an existent mountain with a flattened summit (Mensa). On its boundary with Dorado lies the Large Magellanic Cloud. Only two stars, Alpha and Pi (with a giant planet) are under 100 light-years away.

63P/Wild 1 (2013)

First detected by Paul Wild on a photographic plate exposed on 26 March 1960, who estimated its brightness at a magnitude of 14.3. Its elliptical orbit was then calculated to have an orbital period of 13.21 years. The 2013 return was moderately favorable with magnitude again around 12. [Wikipedia]

 

 

Bamberga (Asteroid)

Semi-major: 2.68477 AU, Size: 235 km

Discovered by Johann Palisa on February 25, 1892 in Vienna. Apart from the near-Earth asteroid Eros, it was the last asteroid which is ever easily visible with binoculars to be discovered - overall the tenth brightest main-belt asteroid. With an unusually long rotation period of 29.43 hours, the asteroid has a mean mass of 1.1x1019kg and a density of 1.52g/cm³.

 

 

Miranda (moon of Uranus)

Discovered in 1948, has one of the strangest and most varied landscapes in the solar system, including three large features known as 'coronae', lightly cratered collections of ridges and valleys. Miranda's giant fault canyons are as much as 12 times as deep as the Grand Canyon. Miranda consist mostly of roughly equal amounts of water ice and silicate rock.

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.
