“In time you may discover everything that can be discovered, and still your progress will only be progress away from humanity. The distance between you and them can one day become so great that your joyous cry over some new gain could be answered by an universal shriek of horror.“
– Galileo Galilei
Did you know Galileo documented his discovery of the Venus phases in an encrypted manner?Our neighboring planet Venus imitates the light figures of Cynthia (goddess of hunting), a poetic name used for the moon. In spring 2020, there is a good opportunity to observe the Venus phases for yourself. Venus appears as an evening star until mid-May and from the end of the year until the end of the year. It plays its role as a morning star. In January, it appears small and rounded in the telescope. It is exciting to see how Venus apparently grows in size over the course of the spring, gradually declining until it presents itself as a large, slim crescent in early May.The race of the two giant planets Jupiter and Saturn can be observed with the naked eye until they can be seen close to each other at dusk deep in the south-west sky towards the end of the year. In March, both gas planets appear in the morning sky. In July, they represent a firmament in the sky all night long. On December 21, 2020, Jupiter finally overtakes the much slower Saturn.
The two are getting closer together than since their last encounter in February 1961.

Eclipses of the Moon & Sun
Sadly, all other eclipses this year remain invisible from Central Europe, such as the one on the 5th of June.
10th of January:
In 2020, a ring-shaped solar eclipse will take place on June 21st and a full solar eclipse will occur on December 14th. In sum, a total of four penumbra eclipses of the moon are happening this year. From Central Europe, as already stated, the only penumbra eclipse that can be observed under good conditions is on the evening of Friday, January 10th. The moon submerges 92.1% of its apparent diameter in the penumbra of the earth. At the height of the darkness, the southern cap shows a light gray veil…though penumbra eclipses of the moon are consideted largely unremarkable nowadays and are barely noticed.
The eclipse is trackable from Europe. Africa and Asia. However, neither the entry nor the exit of the moon from the penumbra can be observed.
The penumbra eclipse takes the following course:
- Entry of the Moon: MET
- In the Penumbra: 18h06m
- Middle of the Darkness: 20h10m
- Exit of the Moon from the Penumbra: 22h14m
In the middle of the eclipse, the apparent diameter of the moon is 92.1% that of the earth. This lunar eclipse is the 16th in the Saros cycle No. 144, which comprises a total of 71 lunar eclipses. The first of this cycle took place on the 29th of July 1749, whereas the last will occur on the 4th of September 3011. The Saros cycle No. 144 stretches over a third-period of 126213 years. The first total lunar eclipse of this cycle is on the 16th of July 2326.
5th of June
This eclipse occurs in the evening hours on Friday, June 5th, 2020. The moon is 59.3 percent of its apparent diameter immersed in the penumbra of the Earth. The slight shading of the southern calotte is quite inconspicuous. This eclipse can be observed in Asia without the northeastern areas and without Japan, eastern and southern Africa, Australia and the Indian Ocean.
The moon rises for 10° east longitude and 50° north latitude on June 5 at 20h12m CET (=> 21h12m CET). By the time the moon has risen above the thickest layers of haze on the horizon, the darkness has progressed so far that it is hardly noticed.
The eclipse proceeds as follows:
- Entry of the moon into the penumbra:
- Middle of the Eclipse: 20h25m / 21h25m
- Exit of the Moon from Penumbra:22h07m / 23h07m
In the middle of the eclipse, 59.3% of the apparent diameter of the moon is in the penumbra of the earth. This is the 67th eclipse of Saros Cycle No. 111, to the total of 71 eclipses. The first eclipse of the Saros Cyle was the penumbral eclipse on the 10th of June 830.
21th of June
Ring-Shaped Solar Eclipse
This eclipse will take place on Sunday, 21th June 2020. In Central Europe, it will remain unobservable even in its partial phases. It is visible in Southeast Europe, in Africa with the exception of the western and southernmost areas, in vast parts of Asia including Japans, in Oceania and in the northern Indian Ocean.
5th of July
Penumbra Eclipse of the Moon
It occurs in the morning hours on Sunday, 5th of Jult 2020. The moon only immerses itself in the penumbra of Earth at 38,000 of its apparent diameter. So this darkness is hardly going to be registered.
