The starry sky offers two exceptional astronomical events in July: the 27th, the longest total lunar eclipse of the 21st century takes place. The same day, the Earth overtakes the reddish Mars, causing an extreme approach to our neighboring outer planet. Mars becomes a bright shining star visible all night long.
The full moon phase takes place on July 27 at 22:20 in the constellation Capricorn. On this day, the moon reaches its lowest point in the morning. It separates then 406 220 kilometers of us. That's why you see the smallest full moon of the year in the evening.
The lunar eclipse on July 27, 2018
At 8:24 pm, the moon enters the shadow of the earth. It remains completely from 9:30 pm to 11:14 pm
With an hour and 44 minutes of total duration, it is the longest lunar eclipse of the 21st century. It is only surpbaded by the lunar eclipse of June 9, 2123, all of which lasts two minutes longer. In addition, the total lunar eclipse of July 16, 2000 was three minutes longer than this year, in terms of total phase. It was the last in the twentieth century to end on December 31, 2000.
With the moon leaving the Earth's shadow at 0:19, the visible part of the eclipse essentially ends. The full moon is the 27th in Germany only after the beginning of the lunar eclipse. In Berlin, the moon rises at 8:58 pm, in Hamburg at 9:17 pm, in Cologne at 9:18 pm, in Leipzig at 8:57 pm and in Munich at 8:57 pm
A little south of the full moon eclipsed in a red light, Mars, which is the 27th, facing the sun on the earthly firmament. The astronomer is talking about opposition position. Due to the extreme position of Mars in the constellation Capricorn, the atmosphere of the Earth provides an additional red coloring – similar to the sun and moon appearing reddish on ancestry and sunset
Mars is particularly close on July 31st. The orbits of the Earth and Mars will reach the shortest distance only on July 31st. On this day, the distance from Mars is only 57.6 million kilometers. This corresponds to about one-third of the Earth-Sun distance. Closer yet Mars arrived at the end of August 2003 with only 55.8 million kilometers. It is only on September 15, 2035 that the red planet will come back with 56.9 million kilometers in the extreme proximity of the earth.
From the beginning of the month until the end of July, Marshellness is still increasing sharply. Mars becomes the dominant star of the night sky. It shines much more than Jupiter, which can still be seen in the first half of the night. On July 1st, Mars will leave half an hour before midnight. At the end of the month, it already crosses the line of the south horizon at half past nine in the evening
The solar eclipse can only be seen from the Arctic Ocean
The new moon is reached on the 13th at 4:48. The same day, the moon reaches 357,430 kilometers near the earth, which in turn causes spring tides and tensions in the Earth's crust. In addition, the new black moon covers nearly a third of the solar disk, a partial eclipse occurs.
It is only in the sea of ice south of Australia, in the south-east of the Indian Ocean and in the South West Pacific. We can still see Sagittarius well after midnight.
Saturn in the constellation Sagittarius can be seen well after midnight. The brightness of the ring planet decreases slightly. His disappearance begins at 5:14 in the morning at the beginning of the month at 3:07 at the end of July
Venus continues to play his role of evening star. Shortly after sunset, you can see them in the sky from the west. Venus slightly increases brightness. However, their visibility is shortened by about an hour. At the end of July, it leaves shortly after half past ten pm
Mercury remains invisible in our latitudes. In the southern countries and in the southern hemisphere, the agile planet is visible at dusk at dusk
Lion and girl disappear
The fixed starry sky now has a summery character. Spring constellations such as Leo and Jungfrau are in decline. Only Arcturus, the main orange star of the boat, is still prominent in the west. The summer triangle with the shining stars Wega in the lyre, Deneb in the swan and Atair in the Eagle conquered the southern sky
The weak constellations Hercules and Serpent Bearer with the Serpent pbad the line midday. Just above the southern horizon, you can see a bright red star: he calls Antares and he is the main star of Scorpio. Scorpio is followed by Sagittarius, which is currently Saturn.
The Big Dipper began his descent. Its drawbar points up, the body of the car hangs. The sky W, the Cbadiopeia, begins in the north-east with its ascent to the zenith.
Days shorten again
On the 6th, the Earth pbades its sunniest orbit at night. Their distance from the star of the day is 152 million kilometers. At the beginning of January, we are five million kilometers closer to the Sun.
The sun began its descent towards the autumn to the celestial equator. On the 21st, she leaves the twins early in the morning and goes to the cancer constellation. A day later, she enters the Leo zodiac one hour before midnight. The length of the day decreases by one hour, the height of the sun at noon decreases by five degrees.
