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.

Piscis Austrinids
15 Jul - 10 Aug, Peak: 7/28
Radiant: Star Chart, Rating: faint
Aldebaran (87 Alp Tau) in Tau [HIP 21421]
Distance: 65 light-years, Magnitude: 0.87
Heralded by the Pleiades, Aldebaran, the primary star in Taurus, is an orange giant which has exhausted its hydrogen fuel. Close to the ecliptic, it can be occulted by the Moon. Aldebaran is a system of six optical double stars. Aldebaran has a metallicity of 70% that of the sun and rotates around its axis once in 642 days. The Romans called it 'Palilicium', in Persia it was known as 'Tascheter'.
Star Chart | DSS IR Image 🔗GJ 699 (Barnard's Star) in Ophiuchus
Distance: 6 light-years, Magnitude: 9.5
Located 5.98 light-years away in Ophiuchus (near the celestial equator), Barnard's Star is a small spectral class M red dwarf star known for its fast motion of 10.358 seconds of arc per year, for which reason it is also called the 'runaway star'. The 10 Gyr old star rotates around its axis in 130.4 days. At its radial velocity towards the sun at 110.6km/s it will make its closest approach around AD 9,800 at about 3.75 light-years. The star's radius is less than 0.2 that of the sun. Barnard's Star is a BY Draconis-type variable.

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.
Star Chart | DSS IR Image 🔗Sagitta (northern), area rank: 86

Located south of Cygnus with Vulpecula in between, this constellation forms a 'Y' and is the third smallest. Sagitta can be found quickly sweeping with binoculars around Altair in Aquila.
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.
Aurora (Asteroid)
Semi-major: 3.16041 AU, Size: 225 km

Discovered by J. C. Watson on September 6, 1867, in Ann Arbor, and named after Aurora, the Roman goddess of the dawn, Aurora is a C-type main belt asteroid, darker than soot and has a primitive compositions consisting of carbonaecous material. Aurora rotates in 7.22 hours. The asteroid has a mean mass of 6.23x1018kg and a density of 1.83g/cm³.
Weywot (moon of Quaoar)

Weywot is the only known moon detected in 2005 around the trans-Neptunian object Quaoar and likely to be a collisional fragment of Quaoar.
