Blue giant stars were not discovered by one person, as they have been observed and studied by astronomers over time. However, they were first classified and extensively studied by Annie Jump Cannon and Ejnar Hertzsprung in the early 20th century.
The closest known blue giant star to our Sun is Spica, which is located in the constellation Virgo and is approximately 250 light years away from us. It is one of the brightest stars in the night sky and is a binary system composed of two stars, with the primary star being a blue giant.
Scientists classify stars by size based on their mass. Stars can be categorized as dwarf stars (like our Sun), giant stars, or supergiant stars, with the size increasing as the mass of the star increases. The classification can also include specific categories such as red dwarfs, white dwarfs, or blue giants, depending on additional characteristics.
No, the black hole will swallow it because it's gravity is much stronger than the blue giant star.
I assume you mean 17 Tauri, one of the stars in the Pleaides cluster. The best information I can find is that it's about six times the radius of the Sun. Despite not being that much larger than the Sun, it's still a "giant" (not on the main sequence). Blue "dwarf" (main sequence) stars are actually not much smaller than the smallest blue "giant" stars, and the difference is determined spectroscopically rather than by size measurements.
A stars color is determined mainly by it's surface temperature. They tend to range from Blue (hottest) thru white and yellow to red (coolest). One thing to bear in mind tho is that a Red Giant star, for example, produces more heat than a smaller yellow star but because the star is much bigger the heat is more spread out (because the surface area is so much bigger) and therefore it appears red.
The blue giant is blue because of the temperature of the gases surrounding the star. These stars are extremely hot.
blue stars are hotter
White Dwarves and Blue giants are both hotter than Red giant stars.
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
usually blue, but some are purple-ish like.
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
Giant stars are commonly referred to as "giant" stars because of their large size compared to main sequence stars like the Sun. These stars are in a later stage of their evolution and have expanded in size due to the depletion of their core's hydrogen fuel.
A blue giant star is made of the same material as other stars. It is made of several types of gases that burn very hotly.
I can't understand this question. There are lots of these stars that are clearly visible. Some of the brightest stars in the sky are these types.

All stars are different but a blue giant will only "live" for about a couple of million years. Our Sun will "live" for about 10 billion years.
