The three bands then correspond to the galactic center of a galaxy in the Hubble field and the interacting galaxy, the center of a bright star in the Magellanic cloud and a star cluster and the last band corresponds to the white dwarf in the Helix and Cat's eye nebulae.
As general relativity predicts, light from the background star bent around the white dwarf, distorted by its gravitational field.
A «brown dwarf» star that appears to be the coldest of its kind — as frosty as Earth's North Pole — has been discovered by a Penn State University astronomer using NASA's Wide - field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes.
Previous ground - based observations characterized all the possible targets in each field (Deleuil et al. 2009); during the target selection, this allowed preference to be given to likely dwarf stars and hence to maximize the probability of finding a transiting planet.
That change caused the minor planet to travel very close to the white dwarf, where the star's strong gravitational field ripped the minor planet apart into gas and dust.

It implies that reliable ages can be derived for field dwarf stars with measured colors and rotation periods, and it promises to enable further understanding of various aspects of stellar rotation and activity for cool stars.
The type of radio emission seen in the brown dwarfs arises in more - massive stars as a result of plasma interacting with the star's magnetic field.
