Amateur Astronomer. Member of Chinese Astronomical Society, Shandong Astronomical Society, Xingming Observatory. I have discovered many new celestial bodies. Asteroid (739634) Zhaojingyuan. My Scientific Publications: https://orcid.org/0000-0002-2770-3481

#astro My collaborators and I discovered M33N 2025-10a, and I also discovered M33N 2011-10a from Palomar Transient Factory (PTF) archive images, all of which were confirmed as outbursts of M33N 2021-08a. These three outbursts make M33N 2021-08a the first confirmed recurrent nova in M33.

I spent almost 2 hours painstakingly copying the orbits of all 128 Saturnian moons from the announcement MPEC and reformatting them for visualization... Behold, here are the orbits of ALL 128 MOONS OF SATURN. This isn't just a moon system—it's a literal asteroid belt around Saturn! 🧪🔭☄️

Saturn's outer moon system viewed from the north pole of Saturn. Moons orbiting in clockwise (retrograde) orbits have red-colored orbits while moons orbiting counterclockwise (prograde; in the direction of Saturn's spin) are colored blue. With so many irregular moons occupying the same region and intersecting each other, the irregular moon system looks like a donut-shaped vortex surrounding Saturn.

Each of the 128 new moons is highlighted in the diagram with a white point representing their location, and a brighter-colored orbit. Previously-known moons of Saturn are included in the diagram, but are colored darker.

The regular moons of Saturn are colored turquoise and the outermost regular moons (Titan, Hyperion, and Iapetus) labeled with their name.

At the lower left corner are scale indicators to help visualize the scale of Saturn's irregular moon system. A small gray circle at the left left corner is shown to represent the diameter of the Earth-Moon orbital distance. A linear scale bar is labeled "10 million km" (6.2 million mi) to give a standard distance.View of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Each moon is labeled with their names in turquioise. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons.Side view of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons.

The irregular moons of Neptune (dark green) are also visible in the background to the right of Saturn. The horizontal red line protruding right of Saturn is the orbit path of Saturn.

Today is paper day! Recently, I discovered two outbursts of the unusual recurrent nova M31N 2017-01e, one new (M31N 2024-08c), one old (M31N 2014-06c). After discussions with Prof. Allen Shafter from San Diego State University, an RNAAS paper was published today. 🔭

【承認】小惑星「アオ(Ao)」命名、漫画『恋する小惑星』にちなんだアプリによる発見 news.livedoor.com/article/deta... 小惑星は『恋する小惑星』の略称にちなんだ未発見小惑星検出アプリ『COIAS』を通じて発見。「アオ(Ao)」という名前は同漫画の2人の主人公が交わした“約束” に由来しているという。

According to the prediction, the recurrent nova T Corona Borealis (T CrB) will outburst in the near future, and global monitoring is very necessary. We sincerely invite amateur astronomers around the world to join our initiative on monitoring T CrB, please read the initiative below.🔭 🧪

Our amateur team has discovered an interesting eclipsing variable star near SH 2-241 nebula from ZTF archive data. It has a period about 830 days, more than 40% in occultation, with a bright peak at the centre of the occultation. 🔭🧪 Image Credit: DSS、PanSTARRS DR1

hep-ex paper of the day: for stars within 500pc of us, SuperK+KamLAND are sensitive to supernova neutrinos---but not just from the core collapse! They'll also see the final hours (up to a day!) of runaway nuclear heating! AND the signal is strongly mass-hierarchy sensitive via the MSW effect! 🧪⚛️

Combined Pre-Supernova Alert System with Kamland and Super-Kamiokande

Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them,...

In an urban area with serious light pollution, the Seestar S50 was used to monitor the upcoming outburst of the recurrent nova T CrB. Because Seestar S50 doesn't have this object in its database, I chose GOTO to the nearby galaxy IC 4587, which places T CrB almost perfectly at the center. 🔭
