2026-03-13 Exoplanets
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.

2026-02-08 solar system
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.

No, we are not on Facebook but proudly on AstroBin with Mille Gracie to the author Salvatore Iovene:

If anybody is interested in the night life of bats, here is a funny 1-minute MP4 video (24MB).
The author's first steps into video editing. They are about Deepsky & Lunar imaging, Milky Way & Constellations, Solar System, Apollo Missions, Artemis II and LROC.

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.

Alzirr (31 Xi Gem) in Gem [HIP 32362]
Distance: 57 light-years, Magnitude: 3.35
Alzirr is a F-class evolved subgiant star with 2.7 solar radii, shining 11 times brighter than the sun. It is an X-ray emitter and rotating rapidly, There is some evidence for a spectroscopic companion star s of equal mass.
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.

M70 (Globular Cluster) in Sagittarius
Magnitude: 7.9
Running away from us at a speed of 200 km/s, this 68 light-year wide cluster of stars is only slightly brighter than its neighboring globular cluster ? M69. Even though it is being ripped apart by tidal forces from being so near to the center of our galaxy, M70 still has a super dense core region, perhaps the product of a core collapse at one point in its evolution.

Located southwest of Canis Major, this constellation depicts the shape of the letter T formed by 3rd-magnitude stars. Modelled after the dove in the Old Testimony, the constellation picture draws a dove holding a branch in its mouth.
Star Chart67P/Churyumov-Gerasimenko

Discovered by Klim Ivanovych Churyumov, who examined a photograph that had been exposed for periodic comet 32P/Comas Sola by Svetlana Ivanova Gerasimenko on September 11, 1969, at the Alma-Ata Astrophysical Institute. The comet's core is 4.1km wide and target of ESA's Rosetta spacecraft mission, launched on 2 March 2004, which woke up from hibernation mode on 20 January 2014 to monitor the comet and select a suitable site for an attempted landing in November 2014 by its Philae lander. The spacecraft arrived at the comet on 6 August 2014. On 12 November 2014, Rosetta's lander Philae was deployed to the surface. The landing site has been named 'Agilkia'. The comet rotates around its axis in 12.4043 hours, its orbital period is 6.55 years, its density is 0.4 g/cm³. So far detected gasses include water, carbon monoxide, carbon dioxide, ammonia, methane, methanol, sodium, and magnesium.
Sylvia (Asteroid)
Semi-major: 3.49320 AU, Size: 384 km

Asteroid 87 Sylvia, discovered in May 1866, has two orbiting satellites. They have been named Romulus (3.65 day orbit) and Remus (1.37 day orbit), the central characters of Rome's foundation myth and the children of the mythological Rhea Silvia. The mean size of Sylvia is 286 km.
Io (moon of Jupiter)

Io is the innermost of Jupiter's 'Galilean Satellites' and the most volcanically active body in the solar system with over 400 known volcanoes producing plumes of sulfur and sulfur dioxide reaching up to 500 km into space. They are kept active by Jupiter's tremendous tidal force and its own tidal heating. Io's surface counts about 100 mountains, but hardly any crater, and if produced, they will soon be filled with lava.
