Q:

Who developed the first catalog of stars and the first map of the skies?

A:

Quick Answer

The name of the first person to map the stars is unknown, although according to David Whitehouse, writing for the BBC, a map of Orion was found etched on a 32,000-year-old ivory tablet. Early star charts may also have been painted on cave walls at Lascaux.

Full Answer

A map of the Pleiades, along with representations of the phases of the Moon, has been found embossed on a bronze tablet, called the Nebra Star Disk, that is dated to approximately 1600 B.C.E., and is associated with the Unetice people of Bronze Age Germany, according to Wikipedia. The disk is the earliest portable map of the sky known to exist.

  • Q:

    How are stars classified?

    A:

    Scientists use a star's temperature to classify it into one of seven main groups referred to by the letters O, B, A, F, G, K and M, in descending order. Within those groups, stars receive a number classification based upon their temperature as compared to other stars within the same group. An additional classification denotes the luminosity of the star through a Roman numeral between I and VIII.

  • Q:

    How do stars function?

    A:

    Stars balance energy released by thermonuclear fusion with gravity based on their massive size. Most stars fuse hydrogen into helium, releasing light and thermal energy. Stars hold together because the large amount of matter involved compresses the gas, forming a luminous sphere. This process is known as hydrostatic equilibrium.

  • Q:

    Why is it that stars twinkle but planets do not?

    A:

    Stars twinkle because they are point light sources. Passing through the atmosphere, the small beam of light constantly shifts by bouncing off particles in the air. Planets are closer, so they appear as discs, with the shifting of light from one side cancelling out the other.

  • Q:

    Why do stars explode?

    A:

    Stars explode either due to gravitational collapse or runaway nuclear fusion. The core of a giant star can become so dense it collapses in on itself, releasing a tremendous amount of energy in one final explosion. Alternately, a white dwarf in a binary system may draw stellar material from its companion star, enough to overload it and create a runaway fusion reaction.
