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.

Zaniar (15 Eta Vir) in Vir [HIP 60129]
Distance: 250 light-years, Magnitude: 3.89
Eta Virginis is a very close triple star system consisting of two stars only 0.5 AU apart with a third slightly more distant star. The inner pair orbits with a period of 72 days while the third companion orbits the inner pair in 13.1 years. Located near the ecliptic, Eta can be occulted by the moon and the planets.
Star Chart | DSS IR Image 🔗GJ 570 A (33 G. Librae) in Libra
Distance: 19 light-years, Magnitude: 5.6
Gliese 570 (33 G. Librae) is a multiple star system with the primary, A, being an X-ray emitting orange dwarf star of 77% solar size. It is separated 190 AUs from the binary components B and C, moving in an eccentric orbit with a period of 2130 years. In 2000, a brown dwarf star (one of the coolests known) has been detected in more than 1500 AU distance from the triple system. The primary has 80% solar masses and measures 74% solar radii.

M49 (Galaxy) in Virgo
Magnitude: 9.3
Elliptical galaxy M49 is the brightest of the Virgo Cluster galaxies and about 60 million light years away spanning an area of 160,000 light-years.
Star Chart | DSS IR Image 🔗Chamaeleon (southern), area rank: 79

Invented in the 15th and 16th century by sea voyagers, this constellation first appeared in Bayer's star atlas in the 17th century as one of the 12 southern constellations. It consists of faint stars and can only be seen in the southern hemisphere owing to its location near the celestial south pole.
Star Chart324P/La Sagra

Discovered on September 14, 2010, main-belt comet 324P/La Sagra, formerly dubbed P/2010 R2, is now the fourth main-belt comet confirmed to be recurrently active, a strong indication that its activity is driven by sublimation. It has the largest confirmed active range of all likely main-belt comets, and also the most distant confirmed inbound activation point at R~2.8 AU.
2012 VP113 (Dwarf Planet)
Semi-major: 271.74058 AU, Size: 450 km

Discovered on November 5, 2012, 2012 VP113 has properties that likely make the 450 km wide (assumed) body a dwarf planet in an highly eccentric orbit at a mean distance of 263 AU. If placed in 1 AU distance, 2012 VP113 would shine like a 4th magnitude star. Its surface is believed to exhibit a pink tinge as a result of chemical formations caused by radiation on frozen water, methane, and carbon dioxide. The discoverer team nicknamed the body "Biden", after the VP od the United States.
Hydra (moon of Pluto)

Hydra is the second largest and outermost natural satellite of Pluto discovered in 2005 by the Hubble Space Telescope. The first well resolved picture of Pluto's small moon Hydra reveals an elongated body with a surface predominantly made of water ice. In addition, scientists have come up with a good estimate for its size: 55km by 40km.
