April of 2021 delivers a few mornings and a few evenings of lunar close encounters, as well as a meteor shower, as we stay up later to get those dark skies.
Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night.
Naked-eye PLANETS...
Sunset – Mars
- Mars (SW-->W) – Look SW and two-thirds of the way up the sky after sunset to find the non-twinkling reddish-orange dot, much brighter than everything around it, above Taurus in the beginning of the month and above Orion toward the end. Sets around midnight in the WNW.
Throughout the night – None at the moment
Morning – Saturn, Jupiter
- Saturn, Jupiter – The two gas giants are low in the SE, getting higher and rising earlier each day. Look SE in the morning (after 5am in the beginning of the month, after 3am by the end). Jupiter will be on the left, with Saturn up and to the right about 15˚.
EVENTS...
Waning Gibbous (Mostly lit, rises later at night)
Last Quarter Moon – 4th (Visible from midnight into the morning)
Morning Crescents (look East in the AM)
New Moon – 11th (darkest skies)
Evening Crescents (look West after Sunset)
First Quarter Moon – 20th (Visible until midnight)
Evening Gibbous (Mostly lit, after Sunset)
Full Moon – 26th (Visible all night)
5th – 7th – Close Encounter – Moon, Saturn, Jupiter – Before sunrise in the SE, between 5am and 6am EDT on these mornings, a beautiful crescent Moon will be passing by our two biggest gas planets. On the 5th, the Moon will be about 13˚ to the right of Saturn. On the next morning (the 6th) the Moon will be just 4˚ under Saturn. Then on the 7th, our crescent Moon hangs out just 5˚ below Jupiter.
15th – 17th – Close Encounter – Moon, Mars, Pleiades, Taurus – Get out there between sunset and midnight to find the crescent Moon in the West right next to Taurus, with the Pleiades on the opposite side, and Mars far above. On the 16th the Moon moves closer to Mars, leaving Taurus and the Pleiades behind. Finally, on the 17th, the Moon is just 5˚above Mars.
22nd – LYRID METEOR SHOWER – 2021 is a decent year for the Lyrids, if you’re willing to get up in the morning to watch. At only 10-20 meteors per hour, it is a minor shower, and we have a Moon just past its 1st quarter, so it won’t get drowned out by moonlight…after 4am. You’ll still be able to see SOME meteors at night, but it’ll be better without the Moon’s light pollution. So look North in general in the morning before dawn. The shower is greatest on the 22nd, but you might see some on the 21st and 23rd as well. Just remember each meteor is piece of debris left over from a comet, and we’re crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash.
Some advice for watching:
Find a dark location and lie down in a reclining chair or something that insulates you from the ground.
Check the weather to see if the skies will be clear
Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.
If you’re feeling extra nerdy, do a scientific meteor count (S&T and IMO)
CONSTELLATIONS...

After Dinner:
Leo, Orion & his winter companions – Leo will be high in the South, almost straight above you. It has a backward question mark with a right triangle to the left of the question mark. Also, take a moment to get your last glimpse Orion, Taurus, the Pleiades, Gemini, Auriga, and Canis Major off in the West.
Before Bed:
Big Dipper, Bootes – If you look above Leo, behind you and high in the sky, you should find the Big Dipper: seven very bright stars that form a spoon shape. Now if you take the handle of the Dipper, follow its curve to the next bright star you see, about 30˚ away, which is Arcturus. “Follow the arc to Arcturus.” That’s the brightest star in Bootes, which looks like a kite. Take that same curve, and follow it about another 20˚ to “speed on to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid.
Before Work:
Lyra, Hercules, Hercules Cluster – Look pretty much straight above you, and find the brightest star up there. You’ll notice a parallelogram attached to it. This is the brightest star Vega, part of the constellation Lyra, the harp. Next to that is a keystone shaped constellation called Hercules. On the right side of the keystone is a small cluster of stars known at the Hercules Cluster, which is a collection of hundreds of stars on the outskirts of our galaxy. Given how high it is in the sky right now, you might catch its faint fuzziness with your naked eye, but a set of binoculars or a small telescope will really help you see it.

The sunshine is coming! March may be bringing some shorter nights and daylight savings time, but the sunshine and warmth during the daytime is very much appreciated! This month Mars dominates the evening sky with Taurus and the Pleiades, and Saturn, Jupiter, and Mercury dance in the morning twilight.
Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night.
Naked-eye PLANETS...
Sunset – Mars
- Mars (SW-->W) – Look SW and two-thirds of the way up the sky after sunset to find the non-twinkling reddish-orange dot, much brighter than everything around it, in between the Pleiades and Taurus in the beginning of the month, moving up throughout. Sets around midnight in the WNW.
Throughout the night – None at the moment
Morning – Venus, Saturn, Jupiter, Mercury
- Saturn, Jupiter, Mercury (SE) – The two gas giants have just started their morning appearances after their conjunction with the Sun in January, so they will be very close to the Sun in the mornings, getting higher and rising earlier each day, but difficult to see without a clear horizon. Look SE well before sunrise (about 6:30am EST in beginning, 6:50am EDT at the end of the month). Jupiter will be the lower and brighter one, with Saturn up and to the right about 10˚. Mercury joins them as well, appearing right in between Jupiter and Saturn, but dives below and to the left of Jupiter on the 6th, getting further away and harder to spot every day.
EVENTS...
Waning Gibbous (Mostly lit, rises later at night)
Last Quarter Moon – 3rd (Visible from midnight into the morning)
Morning Crescents (look East in the AM)
New Moon – 13th (darkest skies)
Evening Crescents (look West after Sunset)
First Quarter Moon – 21st (Visible until midnight)
Evening Gibbous (Mostly lit, after Sunset)
Full Moon – 28th (Visible all night)
8th – 10th – Close Encounter – Moon, Saturn, Jupiter, Mercury – Before sunrise in the SE on these mornings, a beautiful crescent Moon will be passing by three of our planets. On the 8th, the Moon will be about 20˚ (two fist-widths) to the right of Saturn. On the next morning (the 9th) the Moon will advance close to Saturn, only 7˚ away. All the while, Mercury, Jupiter, and Saturn line up from left to right, with slight upward incline. Finally, most spectacularly and most difficult to see, on the 10th the Moon will be directly below these three planets, forming a neat triangle mimicking Capricornus. Definitely worth a shot to see, but make sure your horizon is clear.
14th – Daylight Savings Time Begins at 2am
18th – 19th – Close Encounter – Moon, Mars, Pleiades, Taurus – Get out there between sunset and midnight to find the crescent Moon in the West with red, ruddy Mars close and bright just 4˚ above it. On the 18th, make sure to notice the Pleiades to the right and Taurus to the left, making a wonderful sight. Even better, on the 19th watch the Moon pass very close to Mars, with the Pleiades and Taurus still nearby.
20th – Spring Equinox - Astronomically the first day of Spring, even though meteorologically Spring starts in the beginning of March. Here’s some more info.

After Dinner:
Orion & his winter companions – By 7pm, Orion is about as high as it will get for the night about halfway up the southern sky, tempting us to tour the winter constellations. Begin by finding Orion by looking for three stars in almost a straight line and close to each other, Orion’s Belt, which is surrounded by a bigger, vertical, almost rectangle of stars. Orion will be our guidepost for the other winter constellations. Start at the left belt star and draw a straight line connecting them, then continue that line far past the last belt star about 20˚ or two fist-widths held at arm’s length. There you’ll find the V constellation Taurus, with bright red Aldebaran at the top left of the V. Taurus is part of a big cluster of stars known as the Hyades. Remember that line you just made? Follow it just 10˚ further (one fist-width) and you’ll find a mini-mini-dipper of stars call the Pleiades, which is another open cluster of stars within our Milky Way Galaxy. Let’s go back to the belt, but draw the connecting line from right to left, and continue about 20˚ past the belt, where you’ll find the brightest star in the sky, Sirius. Perhaps you can also see the constellation Canis Major, known as the big dog. We’ll stop there for this month, and pick up next month with Gemini, Auriga, and Canis Minor.
Before Bed:
Auriga, Gemini – Look almost straight up, and you’ll find a pentagon shaped constellation which is the Charioteer Auriga, with its brightest star Capella. Gemini, the twins, will be to the left of Auriga, with bright Castor and Pollux heading them up. For reference, Orion will be below both of them.
Before Work:
Big Dipper, Bootes, Virgo – The Big Dipper should be easy to find in the NW. Follow the curve of his tail or handle to the next bright star you see, about 30˚ away, which is Arcturus. “Follow the arc to Arcturus.” That’s the brightest star in Bootes, which looks like a kite. Take that same curve, and follow it about another 20˚ to “speed on to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid.
