The star eclipse was visible almost everywhere in the United States and most of southern Canada this Sunday (April 10). Even observers in Hawaii were able to see the eclipse, although it was not visible from Alaska.
A growing sickle, 15 percent lit by the Sun, passed in front of a star that looks like an angry orange eye in the constellation Taurus, also commonly known as the Bull.
This star is Aldebaran, the 13th brightest star in the sky and, of course, one of the most colorful of them. This eclipse is known to astronomers as the lunar. When the moon rotates around the earth, it seems, from our point of view, that it is slowly moving eastward relative to the stars, moving approximately its distance in diameter per hour. The rising moon always has a dark edge in relation to the starry background when it moves in its orbit. However, there is an eclipse effect: on most of its path, the moon passed in front of the star during the daytime.
Some observers might think that this would prevent them from seeing the shading, but it is not. Although you, of course, could not see it with the naked eye, still good binoculars or a small telescope allowed you to see Aldebar during the day against a blue sky.
