On january 31st, the hebei news network (reporter zhang huai-sung) will be in the middle of the night tonight with the "super blue moon foods". It is known that most of hebei province has weathered well this evening. At that point, people can watch with their naked eyes。
What's "super blue moon food"? According to professor choi wenwon, professor of astrophysics, school of physical sciences and information engineering, hebei university, this is the three-view astronomical wonders of “the blood moon + super moon + blue moon”, 152 years after their last appearance。
We know that when the moon, the earth and the sun are all on a straight line, the earth is in the middle and the whole moon enters its shadow, forming the whole moon. So, why the "blood moon"? The "blue moon" means the blue moon? How can we be super? And listen to the experts。
The monthly diet is divided into semi-moderated monthly meals, moon appetites and full monthly meals. The middle part of the earth's shadow is known as this shadow, which is half a shadow around it. The moon enters the earth's half-earth, part of the moon enters the earth's own shadow, and all of the moon enters the earth's own shadow。
“at the full moon, the earth's dense atmosphere absorbed and dispersed the relatively short wavelengths of purple, blue, green and yellow, leaving only red light that passed through the atmosphere and was repulsed on the surface of the moon (like the red of the sun at dawn and dusk), so that what we see in the night sky became a red moon, the `blood moon'.” according to choi, “blue moon” is not a blue moon. It means that if two full months in a row fall in the same month of the calendar, the second full month is customarily referred to as the “blue moon” and only happens every two to three years. In addition, the moon happens to be in its public orbit perigee at the time of the full moon, when it appears to be about one tenth larger than usual and is also called “super-lunar diet”
Here is a schedule for watching the full meal this month。
