Unlike most types of stars, which are just as likely as not to have companions and be part of a binary system, an ancient type of variable stars known as RR Lyrae stars seemed to always live out their lives on their own – something that has long puzzles astronomers.

Observations from the NASA/ESA Hubble Space Telescope, collected over the span of five weeks, show the variable star RS Puppis growing alternately brighter and dimmer – a phenomenon known as a light echo.
A new NASA study introduces a cautionary note in the interpretation of rings and spiral arms as signposts for new planets. The team discovered interactions between gas and dust may cause a debris disk, under the right circumstances, to produce narrow rings on its own without a planet present.
Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
Binary Star -- A binary star system consists of two stars both orbiting around a gravitational point between them. The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star - the union of two stars that are formed together in one system by the laws of attraction." At present, binary stars are classified into three types according to their observable properties: visual binaries, spectroscopic binaries, and eclipsing binaries....
