![]() (In 1779, its brightness was briefly a match for that of Aldebaran.) This large range in brightness is exceeded only by another Mira-type star, Chi Cygni, which can go from a very faint magnitude +13 or +14 up to +5 or even +4 in a typical cycle. Mira usually ranges between magnitudes +3 and +9 (lower magnitudes are brighter), although it sometimes gets much brighter. Indeed, the length of Mira's cycle has varied by as much as a whole month. ![]() These stars' brightness cycles take months or years, and their periods are not highly predictable, like the Cepheid class of variables and eclipsing binary stars like Algol. With a period of about 332 days, Mira is the prototype of a large class of long-period variable stars. It appears to rise to its greatest splendor twice as fast as it fades to obscurity. While Tycho's star never reappeared, this one apparently brightened and faded over a time span of roughly 11 months. As the intruder faded gradually from view, it was logical to assume that it was a nova or "new star" like the one that astronomer Tycho Brahe had watched with amazement a quarter of a century before.īut during the winter of 1638, the Dutch astronomer Johannes Holwarda watched this reddish star brighten and grow dim again. But he only stumbled across Mira by accident the star was then near its peak brightness, and he had not noticed the object before, nor did he find it recorded on any of his star maps. The discovery of Mira as a variable star is often attributed to the German astronomer David Fabricius, said to have made the discovery in August 1596. And the word "miraculous" itself comes from the Medieval Latin, "miraculosus." ![]() No doubt, the name Mira was also derived from the word "miraculous," meaning occurring through divine or supernatural intervention. This Latin name is from the book "Historiola Mirae Stellae" ("A Short History of the Wonderful Star") written by the 17th century German astronomer Johannes Hevelius. The star that marks Cetus' head is Menkar, which is about half a magnitude dimmer than Diphda.īut Cetus' main claim to fame is the star found in the lower part of the monster's neck: Mira, the Wonderful. Its brightest star is second-magnitude Diphda, also known as Deneb Kaitos, located in the beast's tail. Something wonderfulĪlthough Cetus is not a particularly bright constellation, it is fairly simple to trace out, largely because it lies in a relatively star-poor region. titles Count in Lemony Snicket books Tesla _ Astrological creation Just because Tiny amount 4/ Aplomb Sports standout Grave Aid in tidying up the house Calendario commencer Musical instrument whose name means "three strings" Four-time World Cup champion How a tie may be broken, for short Whale constellation _ Shah Pahlavi, former leader of Iran Title based on the name "Caesar" Relative of a foil Cavity revealer Breach Godsend Old Roman course Garage services Bump in a ski run Cartoonist who created Fearless Fosdick Part of a spread Lao-tzu and others Somers or Winters Southernmost active volcano on earth Tranquil Silo filler, in brief No longer either hot or cool?
