Astronaut candidates do "parabolic training" on a plane nicknamed the "Vomit Comet" (due to its tendency to induce motion sickness in passengers) so that they can experience weightlessness before being launched into space. If a potential astronauts is found to not be able to handle weightlessness, it's better to find that out before they actually get sent there for a long period of time. Also, weightless training gives them experience in how objects behave in zero-gee, so it's not a surprise when they get there.
In 1066, the comet was seen in England and thought to be an omen.
Comets are named after the people who have discovered it or by the shape or after break away from a parent comet. eg: Halley's comet Tempel-Tuffle comet Biela's comet Encke's comet Ikeya Seki comet kooutek comet comet west comet Bowell comet IRAS -Araki-Alcock Comet Austin.

Halley's comet was named after Edmond Halley, the English astronomer who first discovered that it was a periodic object in 1705. The comet had been seen and recorded as early as 240 B.C., but no one realized it was the same comet in the sky before Halley.
A comet head is the top of the comet like its nucleus is on the top of the comet.
It is important cause they will vomit
Halley's comet is important because it has 5 most important facts about it.
Using the Vomit Comet to experience moments of temporary weightlessness.
thuttt
The Modified B-707 (or K/C-135) used for low gravity training, (astronauts, etc.). It flew a paraboloic curve that simulated weightlessness.
Comet Hale Bopp

Flying in a parabolic arc is the best we can do presently. Astronauts have to take such training aboard the "Vomit Comet"
By themselves, comets are not really important. Even the most impressive comet, like Hale-Bopp, is a visual spectacle only. But the POTENTIAL for a comet - to strike the Earth directly and cause untold devastation - is far more significant. Right now, if we were to see a comet aimed at the Earth, there is very little that we could do about it, other than stand there and die. The threat of a comet impact, like the ones that have devastated our planet several times before, ought to be enough spur us all into looking for ways to protect ourselves from the inevitable time that it WILL happen again.

Halley's Comet was last seen in 1986 and before that it was last seen in 1910.
