Whale constellation _ Whale constellation picture

1 1 month.

Pisces is one of the zodiac signs. Located in the south of Aries and Pisces, between Bojiang and Aquarius, it is a big constellation across the equator.

On the night of late autumn and early winter, we first found the famous Pegasus quadrangle, which extends from the east side of the quadrangle to the south for about twice the distance, and we can see that 1 star with second-class brightness "kills the sky", which is the whale's tail. From this star to the east, you can find 1 third star, which is the whale's nose. This third-class star and four other nearby stars form a pentagon, which is the whale's head.

Learning history:

1959, a star in the constellation Cetacea, but it gradually dimmed and was never seen again after two months. It was not until1665438+February 2009 that people discovered it again. Later, it gradually darkened and disappeared into the vast starry sky a few months later.

After another 60 years, astronomers finally figured out that this is a variable star with a period of 330 days. In fact, this 330 days is only an average, and its darkening period is not fixed at all. The shortest is 365,438+00 days, and the longest is 355 days. It's really a "strange star".

British astronomers have discovered that there are a large number of small celestial bodies around τ star in Cetacea, which is only 12 light-years away from the earth, which is not conducive to the formation of life in this galaxy. This discovery is another blow to people's expectation of finding life outside the earth.

Cetacea τ is the closest sun-like star to the earth except the sun. Because its shape is very similar to the sun and there is a belt around it that may breed planets, many astronomers think that there may be life in this galaxy.
