The Evening Sky for April-May 2018:
Venus is now dominate in the early evening sky and is known as the "evening star" (even though it is not a star but a planet). It's magnitude is around -3.7 making it the 3rd brightest object in the sky only to be outshined by the sun and the moon. Jupiter is rising about an hour after sunset and is very bright (magnitude of -2.3) in the eastern sky at 9 pm. Saturn (Magnitude +0.2) a yellowish bright object with Mars (magnitude -0.38) are both rising around midnight and gaining in brightness. By June and July, Mars will be brilliantly red out-shining even mighty Jupiter.
Note about Magnitudes: The lower the number the brighter the object. For example, the sun's magnitude is -26, the full moon is -12, Venus: -4. The dimmist stars that you can see in a very dark area are around +5. The galaxies are around +7to +12 (except Andromeda which is +3.5)
Galaxies and Star Clusters
The sky though is dominated with deep space objects mainly the galaxies. One of my favorites is the The Whirlpool galaxy is high in the NE by sunset near the handle of the Big Dipper. A cluster of galaxies in the constellation of Virgo is high overhead at midnight with the Sombrero galaxy in the south at the same time. A globular cluster of stars can be found high in the east at 9 pm as well known as Messier 53 (All these pictures taken in my backyard).
