You can discover a comet at home using a telescope.
Look at or take pictures of the night sky. If you see a spot of light that has changed relative position from one night to another (or one week to another...) then this might be a comet.
Maria Mitchell discovered a telescopic comet
Maria Mitchell
Depends. Halley didn't discover the comet, mearly recognised it as a periodic comet from data recorded by Petrus Apianus in 1531 (German) and Johannes Kepler in 1607 (also German). Halley (English) predicted when the comet would return but did not live long enough to see it.
The Comet plasma is created by solar wind. The Comet plasma enables scientists to discover and understand what the solar wind is doing and is very useful.
yes
maria had found her comit in 1881
In 1705 Halley determined the comet's periodicity, but he was not the first person to discover it.
Because someone looked up in the sky and saw it.
I would guess so.Bopp - as in the co-discover of the Hale-Bopp comet - observed the comet in (Stanfield) Arizona, as did the discoverer of Pluto in 1930.
I think the only thing she discovered was "Miss Mitchells Comet"
She didn't invent the telescope, but she used a telescope to discover a comet.
get a telescope, wait until it is dark and stargaze for a while and you might see one
