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.

Sterope (21 Tau) in Tau [HIP 17579]
Distance: 387 light-years, Magnitude: 5.76
Sterope (or Asterope) is a double star separated by 0.047° and designated 21 Tauri (or Sterope I) and 22 Tauri (or Sterope II). 21 Tauri is a blue-white B-type main sequence dwarf with an apparent magnitude of +5.76, while 22 Tauri is a white A-type main sequence dwarf with an apparent magnitude of +6.43.

M18 (Open Cluster) in Sagittarius
Magnitude: 6.9
Located about 4,900 light years and spreading over a 17 light-year expanse of space, this group of around 20 stars is only about 32 million years old. M18's hottest members are spectral type B3, yet it contains many yellow and orange stars as well.

Located in between Taurus and Cancer, Gemini is one of the 12 zodiac constellations. It is characterized by the "brother stars", 2nd-magnitude Castor and 1st-magnitude Pollux. The large open star cluster M35 resides at the feet of Castor.
Star Chart45P/Honda-Mrkos-Pajdusakova

Discovered on December 3, 1948, 45P/Honda-Mrkos-Pajdusakova is a short-period comet on an elliptical orbit with a period of 5.26 years. Its nucleus is estimated to be 0.5-1.6 kilometers in diameter. The comet made a close approach of only 0.06 AU (8,980,000 km) from the Earth on August 15, 2011.
Pallas (Asteroid)
Semi-major: 2.77232 AU, Size: 582 km

Discovered by astronomer Heinrich Wilhelm Matthaus Olbers on March 28, 1802, Pallas, a B-type asteroid is the third largest known asteroid in the main belt. The Palladian surface appears to be a silicate material that is low in iron and water while the surface spectrum and estimated density resemble carbonaceous chondrite meteorites. Pallas' orbit is highly inclined to the ecliptic (38°) and rotates in 7.81 hours. The asteroid has a mean mass of 2.11x1020kg and a density of 2.8g/cm³.
Janus (moon of Saturn)

Discovered in 1966, Janus is an inner moon of Saturn, extensively cratered with several impacts larger than 30 km. Given its low density and high albedo, Janus is obviously a very porous and icy rubble pile 203x185x152.6 km in size. Janus has almost the same orbit as Epimetheus. Epimetheus and Janus may have formed by the break-up of one moon.
