Space Science Notes study notes for college and university students: the study of stars, planets, and other objects in space. Astronomers want to understand the universe and our planet’s.
The Summer Triangle is a set of three stars visible in the summer night sky in the northern hemisphere. It is made up of the stars Altair , Deneb and Vega , all of them of the first magnitude , connecting the constellations of the Eagle, the Swan and the Lyre, respectively, in a clockwise direction. Asterism was traced in the late 1920s by astronomer Owald Thomas … Read more

Tau Ceti . (τ Cet / τ Ceti) It is a star in the constellation Cetus similar to the sun in mass and spectral type. Just under 12 light-years distant from the solar system, it is a relatively close star. It is a star with a low metallic content, from which its low probability of harboring terrestrial planets in its system … Read more
The brightness of a star in the night sky is due to its proximity to Earth, its absolute luminosity, or a combination of the two. Listed below are 91 of the individual stars, ordered by their apparent magnitude in the visible spectrum , measured from Earth. This list would be different if the measurements were made with the naked eye, since multiple nearby stars may … Read more
A star superimán or magnetar is a cosmic magnet. These types of stars are stellar “corpses” whose magnetic field is about a billion times stronger than Earth’s.

The pole star is a visible star that is aligned, at least roughly, with the axis of rotation of the planet Earth . That is, a star whose apparent position is close to one of the celestial poles (the two points in the night sky around which the stars appear to rotate throughout the night) and is exactly at the … Read more
