Sky Watch May 2023: Penumbral Lunar Eclipse and Planetary Views

 May 2023 brings celestial excitement with a penumbral lunar eclipse on the 5th, visible from parts of Europe, Asia, Australia, Africa, and Antarctica[1][3]. Although subtle and challenging to observe, the eclipse will be the deepest penumbral event until September 2042[2]. The eclipse begins at 15:14 GMT, reaches its maximum at 17:22 GMT, and concludes around 21:30 GMT[2]. Observers should ensure clear skies and an unobstructed view of the Moon for the best experience.

In addition to the lunar eclipse, May offers opportunities to observe Mars and Venus in the early evening, with both planets residing in the constellation Gemini[3]. No significant conjunctions occur during the month, but the two planets will be in close proximity, leading to a conjunction in the following month.

For those interested in observing gas giants Jupiter and Saturn, the pre-dawn hours are the best times[3]. Jupiter's visibility improves throughout the month, rising around 4:40 a.m. at the beginning and 3:00 a.m. by the end of May, while Saturn rises just past midnight towards the month's end.

May's night sky also showcases the Spring Triangle, featuring the stars Arcturus, Spica, and Denebola[3]. Eastern skies reveal summer constellations such as Lyra, the Swan, and the Eagle. This month is perfect for observing the Virgo and Coma Berenices constellations, which contain numerous galaxies visible through a telescope[3].
