A comet's orbit showing the different directions of the gas and dust tails as the comet passes the Sun Showing how a comet may appear to exhibit a short tail pointing in the opposite direction to its type II or dust tail as viewed from Earth i.e. an antitail
Showing how a comet may appear to exhibit a short tail pointing in the opposite direction to its type II or dust tail as viewed from Earth i.e. an antitail. An antitail is an apparent spike projecting from a comet's coma which seems to go towards the Sun, and thus geometrically opposite to the other tails: the ion tail and the dust tail.
Comet Hale–Bopp (formally designated C/1995 O1) is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades. [11] [12] [13] Alan Hale and Thomas Bopp discovered Comet Hale–Bopp separately on July 23, 1995, before it became visible to the naked eye.
At that time, the comet's tail will essentially be pointing right at Earth. However, in the days to follow, the tail will pivot eastward, making for dramatic changes in viewing from night to night.
500mm shot of Comet Atlas last night over Ohio. I still can't get over how long the tail is and likely the best comet I'll see in my lifetime.
The comet and its induced magnetic field form an obstacle to outward flowing solar wind particles. Because the relative orbital speed of the comet and the solar wind is supersonic, a bow shock is formed upstream of the comet in the flow direction of the solar wind. In this bow shock, large concentrations of cometary ions (called "pick-up ions ...
The rare comet, Tsuchinshan-ATLAS will be visible in the night sky throughout the rest of October. This is the best time to see it. ... The comet tail is still too dim to see with your eyes, but ...
Through his observations, Apianus was able to prove that a comet's tail always points away from the Sun. [113] In the Sikh scriptures of the Guru Granth Sahib, the founder of the faith Guru Nanak makes reference to "a long star that has risen" at Ang 1110, and it is believed by some Sikh scholars to be a reference to Halley's appearance in 1531 ...
