Magnitude –4 Venus blazes within the west at sundown, seen even whereas the sky stays gentle. An hour after the Solar sinks under the horizon, the twilight has deepened and Venus now hangs like a surprising jewel simply to the decrease left (south) of the Pleiades star cluster (M45) in Taurus. It’s a beautiful pairing that may be loved for a number of hours, lastly sinking out of sight shortly after 10:30 P.M. native time.
By a telescope, you’ll see that Venus’ 15″-wide disk is 74 % lit, its jap half in deep shadow. Close by, the Pleiades are finest seen at low energy by way of binoculars and even your finder scope. As a result of this cluster is so near us — simply 445 light-years distant — it spans virtually 2° on the sky, that means all its stars can’t match inside a extremely magnified discipline of view. Take away any optical help and see whether or not you suppose the naked-eye sight of the celebrities seems like a tiny dipper. Some skygazers suppose that is the Little Dipper when simply beginning out due to this form; the true Dipper lies within the north and covers a a lot bigger space of the sky.
For those who step out significantly early within the night, you’re prone to additionally catch magnitude –0.2 Mercury, which sits nearer to the horizon and units inside two hours of the Solar. We’ll focus right here tomorrow, when the solar system’s smallest planet reaches its best jap elongation.

Jupiter is in conjunction with the Solar at 6 P.M. EDT. This place renders it invisible all month.
So immediately, our focus is Mercury, which reaches best jap elongation 19° east of the Solar additionally at 6 P.M. EDT. Shortly after the Solar disappears this night, step exterior and look west to see should you can spot the innermost planet. Now magnitude –0.1, Mercury stands simply over 10° excessive half-hour after sundown.
By a telescope, Mercury is 8″ extensive and seems slightly below 40 % lit. The planet will shortly start fading from evening to nighttime, although it’s going to stay within the night sky for many of the month. Towards the tip of April, it’s going to “fall” again towards the Solar and, along with fading considerably, may even set earlier every evening because it heads for inferior conjunction Might 1.
Tonight, although, Mercury is in Aries and never removed from one other planet: Dim, distant Uranus additionally sits throughout the Ram’s borders, simply lower than 1° east of Mercury. As a result of the sky will nonetheless be vibrant whereas Uranus is seen, its magnitude 5.9 glow can be unimaginable to identify with the bare eye. As a substitute, use binoculars or a small telescope to slip simply east of Mercury. Your finest guess is to attend for twilight to deepen, however this additionally means the planets can be decrease once you go searching. If attainable, get to larger elevation to spice up your possibilities of catching the ice giant in your eyepiece.

Canes Venatici the Looking Canine is a circumpolar constellation near the North Celestial Pole. Its two brightest stars lie south of the curve within the Massive Bear’s elongated tail (additionally drawn because the deal with of the Massive Dipper). Magnitude 2.8 Cor Caroli (Alpha Canum Venaticorum) is a few 17.5° due south of Alioth (Epsilon [ε] Ursae Majoris), the third star in from the tip of the Massive Dipper’s deal with. By a telescope, the star splits into a good looking binary star with elements practically 20″ aside. The extra luminous sun is blue-white, whereas its dimmer companion shines with a yellowish hue.
Cor Caroli additionally serves as a jumping-off level tonight for our second goal: Upgren 1, some 5° southwest of this star. Cataloged in 1963, Upgren 1 seems a bit like a small triangle of stars by way of binoculars or a small scope. Although initially believed to belong collectively as a cluster, these stars aren’t actually related and as a substitute are an opportunity superposition. This makes Upgren 1 an asterism relatively than a real cluster.

At magnitude 0.9, will probably be seen to the bare eye till the sky grows too gentle, floating within the comparatively sparse area of southwestern Aquarius.
For this goal, you’ll undoubtedly wish to pull out a telescope when you have one. The planet’s disk spans some 16″, whereas its rings stretch greater than double that. You might also spot Saturn’s largest and brightest moon, Titan, far west of the planet, sitting some 2.5′ away. The moon will attain its best western elongation from Saturn early tomorrow morning.
