VISNJAN, June 12 (Hina) - A bright star, hitherto unmarked on
astronomical charts, was spotted in the Scorpio constellation by
telescopes at an observatory at Visnjan, on the Croatian peninsula
of Istria, at 3 a.m. on May 23.
The discovery was immediately communicated to the nearest
observatories and the International Astronomical Union at Harvard
University in the United States, a statement from the Visnjan
observatory said on Wednesday.
Subsequent research has shown that the star is so distant that
it takes several dozens of thousands of years before its light
reaches the Earth.
The newly-found star, with a radius of 400 to 500 million km
(the Sun has a 1.5 million km radius), is so big that it would
engulf the Earth if it were situated in our galaxy.
Since the star is old and has nearly exhausted its nuclear
fuel supply, it pulsates and changes its brightness more than a
thousand times in over 400 days. The star's bright red colour
indicates that its temperature is about 2,300 degrees Celsius.
The first such star was discovered by the Dutch astronomist
David Fabricius on August 13, 1596, and was called "Omicron ceti".
In 1662, astronomers noticed that its shine rises and falls
periodically so they called it Mira (Latin for admirable or
wonderful). After that, all newly-discovered stars with similar
features are given the name "Mira".
