Sirius and Its White Dwarf Companion

Description
Sirius and Its White Dwarf Companion
(a) Sirius, the brightest-appearing star in the night sky, is actually a double
star. The smaller star, Sirius B, is a white dwarf, seen here at the five
o’clock position in the glare of Sirius. The spikes and rays around the
bright star, Sirius A, are created by optical effects within the telescope.
