This unique spiral galaxy, which is situated 3.2 billion light-years from the Earth, has an extended stream of bright blue knots and diffuse wisps of young stars. [2] It rushes at 3.6 million km/h (1000km/s [2]) through the cluster Abell 2667 and therefore, like a comet, shows a tail, with a length of 600,000 light-years.
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.
Comet Tucker, formally designated as C/2004 Q1, is a faint non-periodic comet that had a very distant perihelion on 11 December 2004. It was the second of two comets discovered by famed amateur astronomer, Roy A. Tucker .
The host star of IRAS 04125+2902 b is IRAS 04125+2902, a T Tauri variable [5] located at 520 light-years from Earth. [1] It has cool effective temperature and a spectral type M1.25 ± 0.25. [ 6 ] Despite its cool temperature and late spectral type, this star is larger than the Sun, mostly because of its young age. [ 1 ]
Little is known of what people thought about comets before Aristotle, who observed his eponymous comet, and most of what is known comes secondhand.From cuneiform astronomical tablets, and works by Aristotle, Diodorus Siculus, Seneca, and one attributed to Plutarch but now thought to be Aetius, it is observed that ancient philosophers divided themselves into two main camps.

The comet was first spotted as a magnitude 16.4 object by the ASAS-SN survey from images taken at the Cerro Tololo Observatory's 14-cm "Cassius" telescope between 7–11 July 2018. [ 3 ] [ 4 ] It made its closest approach to Earth on 19 October 2019 at a distance of 205 million mi (330 million km) before reaching perihelion on 11 November 2019.
The comet reached a brightness of 0–1 mag on November 29. [2] In Europe, the comet was observed by many astronomers from the end of November. Johannes Kepler saw it in Linz on the morning of November 29th and was able to measure its orbit until January 7th. [6] The Swiss Jesuit Johann Baptist Cysat observed the comet from Ingolstadt from ...
