Have there been any recent astronomical phenomena?

Let's not talk about the past.

Solar and Lunar Eclipse: March 19, partial solar eclipse.

On August 28, the moon is eclipsed.

Planets: June 6, Jupiter at opposition.

On December 23, Mars opposes the Sun.

In August, Venus was at a great western elongation and is now a dusk star, and the observation conditions are getting better and better.

Mercury City is hard to see, so let's not talk about it.

Meteor shower: April 22 Lyrid meteor shower 20

May 6 Aquariids 50

August 12 Perseid meteor shower 100

September 1 (highly recommended) Auricorn Meteor Shower 100012 14 Geminid meteor shower 120

December 28 Ursid Minor meteor shower 50

Especially on September 1. The landlord can observe as long as the weather is good, and you can definitely find a place with absolute magnitude in the city, according to my calculations, more than 40 meteors can be seen in the hour, counting meteors in the moonlight, which can not be considered enjoyment?

In addition, it is unpredictable to know all comets. Comet 2006p1 (McCotro) a few days ago has magnitude -4! Brightest in 10 years!

Maybe a supernova; Iridium, the International Space Station is also an object that can be observed.

There was a lunar eclipse at 01:00 the night before

Also, tomorrow morning you can see the sun rising

September 1 (highly recommended) Auricorn 1000"It was my birthday! It's romantic to think about!

<> astronomical phenomenon is a total solar eclipse.

Partial solar eclipse, annular solar eclipse, total lunar eclipse, partial lunar eclipse, etc.

1. Total solar eclipse: A total solar eclipse is a solar eclipse.

It is an astronomical phenomenon in which the sun's rays are completely obscured by the moon in some parts of the earth.

2. Partial solar eclipse: when the moon.

Orbiting between the Earth and the Sun, when the Earth orbits to the penumbra of the Moon, there is an area of the Earth that is partially covered by the penumbra on the outer side of the Moon's shadow.

3. Annular solar eclipse: An annular solar eclipse is a type of solar eclipse. It occurs when the central part of the sun is dark and the edges are still bright, forming a halo. This is because the Moon is between the Sun and the Earth, but it is far away from the Earth and cannot completely cover the Sun.

4. Total lunar eclipse: A total lunar eclipse is a lunar eclipse.

When the moon, the earth, and the sun are completely in a straight line, the entire moon walks into the shadow of the earth, and the surface of the moon is dim, forming a total lunar eclipse.

5. Partial lunar eclipse: A partial lunar eclipse occurs when only part of the Moon enters the Earth's umbra. When a partial lunar eclipse occurs, the moon will appear half white and half bronze.

25th, 16:22: The moon passes over the node.

27th, 01:03: First quarter moon.

29th, 10:30 p.m.: Mars conjunct Andearc, Mars is located north of Contarest.

The appearance of a double crescent moon on the moon is a rare spectacle. Unless the most excessive drinking is seen as a double.

For astronomy enthusiasts, July 22 is a once-in-500-year feast. This total solar eclipse lasts more than 2 hours from the beginning of the eclipse to the full circle, and the duration of the total solar eclipse can reach about 6 minutes at the longest. It was the longest total solar eclipse observed in China between 1814 and 2309, and the largest total solar eclipse in world history.

The characteristics of this total solar eclipse are: First, the number of people covered is very large, reaching more than 300 million people, which is unprecedented in the history of the world. Second, it covers a very wide observable area, with the entire daily zone reaching tens of thousands of kilometers, which is equivalent to the length of the Yangtze River in China.

Over such a vast area, hundreds of millions of people have observed a total solar eclipse.

The formation of a total solar eclipse is a phenomenon caused by the geometric relationship between the orbits of the Sun, the Earth, and the Moon. In today's celestial mechanics calculations, it is possible to accurately calculate when a solar eclipse will occur and when a lunar eclipse will occur in what year, just as we can predict what time the sun will rise and what time it will set every day. [

All total solar eclipses are invaluable to researchers. Why? During a total solar eclipse, the moon obscures the sun.

In this way, the sun that we usually see is very bright, but there is actually a coronal structure next to the sun. The corona is very dark, and its brightness is only one to two millionths of the surface of the sun. So I can't see it every day.

The total eclipse of the day just obscures this light, so the beautiful corona next to it will be visible. In this book, you can see that this is a total solar eclipse, which is the corona, which is usually not visible. So we can see a very beautiful structure, this very beautiful structure for scientists is most concerned about the physical processes inside, what is its temperature, what is its density, this is a good opportunity for us scientists.

Because now that we have the means of space observation, we can directly observe the corona by putting observation instruments into space. But at a time when we didn't have the means to put instruments into space before, the only chance to observe the corona on the ground was when a total solar eclipse occurred, which is an important reason why many scientists paid attention to total solar eclipses, that is, the corona could be observed on the ground.

1. The celestial phenomena that can be used include: the phenomenon of occult food between celestial bodies and celestial bodies, mainly such as "eclipse", "occult bridge", "ling" and other phenomena.

2. The position of the circular celestial body forecast, such as the position of the sun, moon, planets, planetary moons, and asteroids, and the relative position of the celestial body to the earth and the sun.

3. The relative position of the moon and the earth: the first quarter - the second quarter - the second quarter - the far (near) position of the moon.

4. The apparent motion of the inner planets: upper conjunction, eastern elongation, staying, inner conjunction, remaining (inferior), remaining - western elongation, upper conjunction.

5. The apparent motion of the outer planets (asteroids): stay-opposition-stay-conjunction, the apparent position of celestial bodies and celestial bodies is close, such as planetary conjunction with the moon, double (three or more) stars with the moon, Saturn conjunction with the ghost star cluster, five-star alignment, etc.

An annular lunar eclipse is an astronomical phenomenon that is impossible.

A lunar eclipse occurs when the Earth is between the Sun and the Moon, and the three spheres are basically in a straight line. The Earth is four times the diameter of the Moon, much larger than the Moon, and will block all sunlight, so it is impossible to form an annular lunar eclipse.

Since the diameter of the earth is 4 times that of the moon, when the sun, the moon, and the earth are in a straight line, and the moon is in the middle, the sunlight can reach the earth through the moon's limbs, forming an annular solar eclipse, while on the contrary, the light that hits the moon when the earth is in the middle is completely blocked by the earth, and it cannot reach the moon, so it cannot form an annular lunar eclipse.

Even in the orbit of the Moon, the diameter of the Earth's umbra is still twice that of the Moon, much larger than the Moon, blocking sunlight, and the length of the Earth's umbra is about twice the average distance between the Moon and the Earth, and the diameter of the Moon is much smaller than the diameter of the Earth, so it is impossible to form a lunar mill annular eclipse.

An unlikely astronomical phenomenon is an annular lunar eclipse. Since the diameter of the Earth is 4 times that of the Moon, even in the orbit of the Moon, the diameter of the Earth's umbra is still twice that of the Moon, much larger than that of the Moon; The Earth, on the other hand, blocks sunlight, and the length of the Earth's umbra is about twice the average distance between the Moon and the Earth, and the diameter of the Moon is much smaller than the diameter of the Earth, so it is impossible to form an annular lunar eclipse. <
