On the morning of january 31st in nanjing, xinhua news agency (journalist chen zheng yuan), many friends' circles were painted by the super blue moon。
What time is the best night? What do you mean, super moons, blue moons, all moons? How can the moon be blue and red at the same time? In response, journalists interviewed the science scholars of the purple mountain observatory of the chinese academy of sciences。
An alarm bell was set and the moon was “until dark times” at 2129 hours。
Zhang zhang zheng, director of science and technology at the purple mountain observatory of the chinese academy of sciences, told the journalists that, as long as the sky is beautiful, most parts of the country will be able to observe this rare event directly with their naked eyes tonight. The whole of the eclipse is visible in the central east. The western parts of tibet and the western parts of xinjiang do not see the beginnings and initial losses, but the process can be followed。
It is projected that the semi-film food phase of the monthly diet will begin at 18:51 beijing time and the moon will start to be ash from the bottom left; the initial loss will occur at 19:48, when there will be a gap at the bottom left of the moon。
“the most exciting full-eat phase will begin at 20:51, when the moon will enter the earth's face completely, presenting the palaeonous light, that is, the `red moon' that you usually understand.” according to zhang zhang, “it occurs at 21:29, when the moon enters the deepest part of the earth's landscape, which is also the darkest moment on its surface”
The whole meal phase will end at 22:07 and the light will return to the bottom of the moon until the return of round 23:11 and the full full moon will resume until 00:08 on 1 february。
"the sky dog eats the moon" is a popular interpretation of the whole moon. When the whole of the moon occurs, the moon becomes dim and eventually becomes dark red, and when the eclipse ends, it returns to its brightness, known as the “red moon”. The day attracted widespread attention not only because of its rareness, but also because of the name of the blue blood moon。
“the principle of the full moon is that the moon runs into the shadows of the earth, which has blocked the sun from its original light.” zhang zhang explained that, because the earth's atmosphere was refractioned and dispersed to the sun, the longest-length red light of which fell most on the moon, the moon would appear in dark red and the whole of the moon would become “blood moon”。
The blue moon is not a blue moon, but a second full moon in the same month. "as a general rule, the time between full moons is about 29. 5 days, i. E. On astronomy. A time difference arises when the number of calendar days per month is typically 30 or 31 days. So, on average, after 32 months, there are two full moons in a calendar month, the "blue moon." zhang zheng told journalists that there were two full months in january of this year, the last one on 2 january。
In addition, the term “super moon” refers to a larger and brighter moon when it runs to its perigee; in contrast, the term “mini moon” means that when the moon runs to a distant location, in visual terms, “super moon” is generally 14 per cent larger than the term “mini moon” and 30 per cent more bright。
The “super moon” is common, but it is rare to see it at the same time as the full moon and, by chance, in the same month as the last full moon. “the blue moon is no different from the usual full moon, so tonight the public is still seeing a red moon created by the whole diet.” zhang said。
