Crescent Moon Occultation
Explanation: On February 22, a young Moon shared the western sky at sunset with bright planets Venus and Jupiter
along the ecliptic plane. The beautiful celestial conjunction was
visible around planet Earth. But from some
locations Jupiter hid for a while, occulted by the crescent lunar disk. The Solar System's ruling gas giant was captured here just before it disappeared behind the the Moon's dark edge,
seen over the RÃo de la Plata at Colonia del Sacramento, Uruguay. In the serene river and skyscape Venus is not so shy, shining brightly closer to the horizon through the fading twilight. Next week Venus and Jupiter will appear
even closer in your evening sky.

These days, Jupiter also becomes "evening star" by definition as sometimes and in turn it's up to Mars or Saturn. In Astronomy it is said that the morning and evening stars can be any bright object on the morning or evening horizon. I had to see the mornings one cool morning before sunrise when I was about 5 years old, a spectacle that I still remember and that impacted me forever, they were Venus and possibly Jupiter quite approximate silhouetted on the eastern horizon in a sky without Luna, for the patience of an older brother who was getting ready to go to the factory where he worked.-
Years later he followed Venus every afternoon until it disappeared behind the horizon and in a few days he reappeared on the morning horizon to be the morning star.

You could if you like call Jupiter an evening star this week. But Venus is also out and so we have TWO evening stars this week. They are actually getting closer the next few days, and in the night of the 28th or March 1st, (I am not sure which night it is) they are practically going to touch! Then they'll combine into one bigger evening star

Hi All,
I'm sure there's a logical explanation for this, but why do they appear reversed, as though they are rising rather than setting? This is how the setting crescent moon appears in my Newtonian reflector, which reverses the image.
Many thanks,
Darren

This is also the second time I have encountered this situation
cookie clicker, a friend of mine said that the moon will be different with each season of the year.
