When the orbital plane of the comet and Earth roughly align, the otherwise faint heavy dust left behind a comet appears as a spike pointing towards the Sun. It is quite common among comets. Bright comet Tsuchinshan-ATLAS last year had one too.

A Unique Moment. Images of the Comet that Passed by Earth
C/2023 A3 Tsuchinshan-ATLAS is not expected to approach our planet again for hundreds of thousands of years. After months of anticipation by astronomers and night sky observation enthusiasts, it was finally possible to witness the passage of comet C/2023 A3 Tsuchinshan-ATLAS. This comet, originating from the Oort Cloud, was observed all over the world this Sunday, the 13th, and beautiful images of its passage were also captured in Portugal.

NASA Astronomy Hourly Picture - 2024-11-27: The Meteor and the Comet
#Astronomy #NASA #Space
How different are these two streaks? The streak on the upper right is Comet Tsuchinshan-Atlas showing an impressive dust tail. The comet is a large and dirty iceberg that entered the inner Solar System and is shedding gas and dust as it is warmed by the Sun's light. The streak on the lower left is a meteor showing an impressive evaporation trail. The meteor is a small and cold rock that entered the Earth's atmosphere and is shedding gas and dust as it is warmed by molecular collisions. The meteor was likely once part of a comet or asteroid -- perhaps later composing part of its tail. The meteor was gone in a flash and was only caught by coincidence during a series of exposures documenting the comet's long tail. The featured image was captured just over a month ago from Sichuan Province in China. Gallery: Comet Tsuchinshan-ATLAS in 2024

El cometa Lemmon

Hace un par de semanas me alejé de la contaminación lumínica de la ciudad de México junto a unos amigos para cazar al cometa C/2025 A6 Lemmon.

Puedo decir que son mis mejores fotos de un cometa, superado en detalles al Tsuchinshan-ATLAS del año pasado.

The key to understanding the - to many - bewildering images of 3I from 9 + 10 November was the viewing geometry in combination with dust tail theory: what we saw matches simulations like groups.io/g/comets-ml/... well. (How antitails work was also amply demonstrated by Tsuchinshan-ATLAS last year.)

NASA Astronomy Hourly Picture - 2024-09-30: Comet Tsuchinshan-ATLAS over Mexico
#Astronomy #NASA #Space
The new comet has passed its closest to the Sun and is now moving closer to the Earth. C/2023 A3 (Tsuchinshan–ATLAS) is currently moving out from inside the orbit of Venus and on track to pass its nearest to the Earth in about two weeks. Comet Tsuchinshan-ATLAS, pronounced "Choo-cheen-shahn At-less,", is near naked-eye visibility and easily picked up by long-exposure cameras. The comet can also now be found by observers in Earth's northern hemisphere as well as the south. The featured image was captured just a few days ago above Zacatecas, Mexico. Because clouds were obscuring much of the pre-dawn sky, the astrophotographer released a drone to take pictures from higher up, several of which were later merged to enhance the comet's visibility. Although the future brightness of comets is hard to predict, there is increasing hope that Comet Tsuchinshan-ATLAS will further brighten as it enters the early evening sky.

NASA Astronomy Hourly Picture - 2024-10-21: Comet Tsuchinshan-ATLAS over California
#Astronomy #NASA #Space
The tails of Comet Tsuchinshan-ATLAS were a sight to behold. Pictured, C/2023 A3 (Tsuchinshan–ATLAS) was captured near peak impressiveness last week over the Eastern Sierra Mountains in California, USA. The comet not only showed a bright tail, but a distinct anti-tail pointing in nearly the opposite direction. The globular star cluster M5 can be seen on the right, far in the distance. As it approached, it was unclear if this crumbling iceberg would disintegrate completely as it warmed in the bright sunlight. In reality, the comet survived to become brighter than any star in the night (magnitude -4.9), but unfortunately was then so nearly in front of the Sun that it was hard for many casual observers to locate. Whether Comet Tsuchinshan-Atlas becomes known as the Great Comet of 2024 now depends, in part, on how impressive incoming comet C/2024 S1 (ATLAS) becomes over the next two weeks.

On January 24, 2026, astronomers anticipate the closest approach of Comet Tsuchinshan-ATLAS (2023 F1) to Earth. While not expected to be visible to the naked eye, this comet is being closely monitored due to its potential for increased brightness as it nears the inner solar system. This close fly...

The comet C/2023 A3 (Tsuchinshan–ATLAS) reached its perihelion on Sep 27 2024, at a distance of 0.391 AU from the Sun.

I photographed it in Oct 2024.
