We mark on the calendar 1 and 2 Aprilbecause they will be unforgettable evenings: the Moon it will in fact be immersed in the stellar ambassador of the Pleiadi the first day of the month, while the following evening will give a “Kiss” to Jupiter. Both shows – time permitting – will be visible to the naked eye. And there is more: because we can also admire the early stages ofconcealment of the Pleiades.
The concealment of the pleaids
As the UAI explains, on 1 April the subtle crescent moon sickle in the constellation of the bull approaches Pleiadi up to the initial stages of a suggestive concealment that we will not be able to observe in all its phases because the meeting between these stars takes place when they are already close to sunset (on the map the Heaven of April 1, 2025 at about 20.30).
Concealment is a phenomenon very similar to eclipseas it occurs when a celestial object passes in front of another, temporarily hiding it from sight. In the case of the eclipses we speak more correctly than Shadow projectedbut there is another difference between the two phenomena, such as explains NASAwho writes:
Concealmentthat is, when an object passes in front of another object with much smaller apparent dimensions, like the moon that passes in front of a distant star
Which is precisely the case that awaits us on the evening of April 1st.
And that is not only a suggestive visual phenomenon, it is in fact “used” even in astronomical research: it can in fact provide precious information on the size, shape and atmospheric properties of the planets and other worlds. For example, in 1977, Uranus rings were discovered by Kuiper Airborne Observatory of the NASA just when the planet occupied a star.
And then – we always say it – the Pleiadi They are also a spectacle: in fact the stellar cluster, far from sources of light pollution (which is in fact becoming a huge problem), there Show up to 12 stars And anyway, if the weather is Clemente, it is not difficult to count 4 or 5 even in the city.
The “kiss” moon-game
But it does not end here, because the following evening, on April 2, the Falce di Luna continues its path in the constellation of the Taurus, where it will enter the conjunction with the planet Jupiter, and also this show – time permitting – will be visible to the naked eye (on the map the Heaven of April 2, 2025 at about 20.30).
Not to be missed!
