The constellations of Canes Venatici and Coma Berenices can be found above the handle of the famous asterism of the Big Dipper (Figure 3). Both constellations are rich in deep-sky objects and also host several prominent galaxies. The Whirlpool Galaxy (M51), Sunflower Galaxy (M63), Cat's Eye Galaxy (M94), Whale Galaxy (NGC 4631), Hockey Stick Galaxies (NGC 4656 and NGC 4657, Cocoon Galaxy (NGC 4490), the spiral galaxy M106, and the bright, large globular cluster M3, are only some deep-sky objects that are observable in Canes Venatici (Figure 2).

Cor Caroli, a binary star system and the brightest star in Canes Venatici, serves as one of the vertices of a prominent spring asterism called Great Diamond or Diamond of Virgo. The other vertices of the asterism include Arcturus, Spica, and Denebola from the constellations of Bootes, Virgo, and Leo, respectively [1]. Figure 3 shows the view of the Great Diamond if an observer is looking north on the night of 15 May at 9:00 PM.

Coma Berenices also hosts numerous deep-sky objects, including the Black Eye Galaxy and the globular cluster M53. Coma Berenices is also the home of the Coma Cluster of galaxies, a cluster of at least 10,000 galaxies, mostly elliptical galaxies, and also the northern part of the Virgo Cluster including M85, M88, M91, M98, M99 (Coma Pinwheel), and M100, the grand design spiral galaxy. Figure 4 shows the location in the sky of some deep-sky objects in Coma Berenices.

Located south of Coma Berenices is Virgo, the second-largest constellation, next to Hydra. Virgo also contains numerous Messier objects, including the famous Sombrero Galaxy (M104) and the galaxies belonging to the Virgo Cluster, namely, M49, the brightest member of the cluster, M58, M59, M60, M61, M84, M86, M87 (also known as Virgo A), the largest and one of the most massive galaxies in the cluster, M89, and M90. Figure 5 shows the position of the galaxies (magnitude < 10) belonging to the Virgo Cluster.

Centaurus and Crux are the best known southern constellation. Centaurus is the ninth-largest constellation in the sky containing 10 stars brighter than magnitude 3.00. Centaurus is also the home of Omega Centauri, the brightest globular cluster. Meanwhile, Crux, also known as the Southern Cross, is the smallest constellation in the sky and is used for navigation towards the true south [2].
A close pairing of the planets Venus and Jupiter will be on 1 May at 04:56 AM. The pair will be located in Pisces and will be merely 13.8" from each other. The close pairing is observable from 3:30 AM until before sunrise (Figure 6) [3, 4]. Meanwhile, Venus and the waning crescent Moon, both in Pisces, will be 10.9" away from each other on 27 May. The exact moment of the close approach will occur at 11:03 AM, but the pair may still be observed early morning until before sunrise. Figure 7 shows the view Venus-Moon pairing on the eastern horizon on 27 May. The angular separation of these pairings is close enough to fit in the field of view of a telescope. However, the pairing is also visible to the naked eye or through the aid of a pair of binoculars [5, 6].
The planets Jupiter and Mars will be merely 34.9" from each other on 29 May at 6:26 PM. The pair will not be observed at the exact moment of the close approach since it is still below the horizon. However, the pairing is observable as soon as it rises in the east at around 2:00 AM until before sunrise. Figure 8 presents the view of the eastern sky during the close approach of Jupiter and Mars on 29 May 2022 at 4:00 AM. The planetary pairing has a little too wide angular separation, which cannot fit into the field of view of a telescope but will still be visible to the naked eye or through a pair of binoculars [7, 8]. A few days prior, the waning crescent Moon can be observed close to the planets Jupiter and Mars on 25 May [9]. The view of the trio, located in Pisces, is observable in the east from around 2:00 AM until before sunrise. Figure 9 shows the eastern horizon at 4:00 PM on 25 May during the Jupiter-Mars-Moon pairing.

Saturn and the waning gibbous Moon will closely approach each other at about 411' on 22 May, 3:20 PM. The exact moment of the pair is not directly observable since it will occur in the afternoon, and both Saturn and the Moon are still below the horizon. However, the close pairing is observable on the same day but from around 1:00 AM until before sunrise. Figure 10 shows the view of the Saturn-waning gibbous Moon pairing on 22 May at 4:00 PM [10, 11].
