The 29 Canis Majoris is a binary star which belongs to the Beta Lyrae variable class. The star then turns into a red giant. According to stellar evolution theory, it is a massive star entering the latter part of its life, having exhausted most of the hydrogen . (red supergiant stars are large but usually have low luminosity). Red supergiants are a class of star that end their lives in supernova explosions. Binary stars can be invisible See more ideas about universe, stars, astronomy. Based on extensive research in the archives, this biography of Walter Baade is an impressive contribution to the history of astronom."--Karl Hufbauer, author of Exploring the Sun The time it will take to travel to this star is dependent on how fast you are going. A blue giant star is also an old star, but this star burns helium at a much hotter temperature, which is what gives it that blue appearance A supergiant star can be as large as a solar system, and tends to be blue in color (we'll have more for you on this star in just a moment) In fact, they attain the central role and position in cosmic bodies, owing to the energy that they produce. It's very tiny, but very dense. The true monsters of the Universe are blue supergiant stars, like Rigel. In general terms, red giants stars represent the late evolutionary stage of low-mass stars, whereas red supergiants stars are the late evolutionary stage of high-mass stars.
