A crowded galaxy field on a black background, with one large star dominating the image just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many other are red or orange. Even without zooming in, different galaxy shapes are detectable, like spirals, ovals, and arcs.

This starry view of the nearby star-forming region IC 348 is one of the largest images from the NASA/ESA/CSA James Webb Space Telescope released to the public so far. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered brown dwarfs just twice the mass of Jupiter, bringing the study of these curious objects into a new mass range.

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. …

On Feb 6, 2026, NASAs SPARCS Mission returned first images of an exoplanet, HD 71262, in both, near-UV and far-UV. SPARCS' mission is for monitoring flares and sunspot activity on low-mass stars about 30% to 70% the mass of the Sun which are likely to host rocky planets inside their habitable zones.

AR4366 stands out as the most active sunspot of early 2026, producing an extraordinary sequence of high‑energy flares and posing meaningful space‑weather risks as it faces Earth. Its behavior is characteristic of a highly unstable, rapidly evolving magnetic system capable of generating the strongest solar eruptions of the cycle. Ø71mm APO, IMX178 camera.

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.

Persian (Alp Ind) in Ind [HIP 101772]
Distance: 101 light-years, Magnitude: 3.11
The 3rd magnitude primary star in Indus is a class-K giant star which has twice the mass of the sun and has expanded to 12 times the solar radius. There may be two unconfirmed M-type companions some 2000AUs away. In China, its name is Pe Sze (meaning Persia), and is also known as 'The Persian'.

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.

Star Chart103P/Hartley 2 (2010)

Comet Hartley 2 is a small periodic comet with an orbital period of 6.47 years. It was discovered by Malcolm Hartley in 1986 at the Schmidt Telescope Unit, Siding Spring Observatory, Australia. Its diameter is estimated to be 1.2 to 1.6 km while its mass is estimated to be about 300 megatons. The comet was the target of a flyby of the Deep Impact spacecraft, as part of the EPOXI mission, on 4 November 2010, which was able to approach within 700 km as part of its extended mission. As of November 2010 Hartley 2 is the smallest comet which has been visited.
Metis (Asteroid)
Semi-major: 2.38602 AU, Size: 235 km

Discovered by Andrew Graham on 25 April 1848, at Markree Observatory in Ireland, Methis is an S-type main belt asteroid composed of silicates and metallic nickel-iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. Light curve data indicated a satellite, but subsequent observations failed to confirm this. Metis rotates in 5.079 hours. The asteroid has a mean mass of 1.47x1019kg and a density of 4.12g/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.
