Lunar Eclipse Month!!! Get ready for a May that boasts a wonderful blood moon and an array of morning planets all month long.

         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 – Mercury (first week of May)

• Mercury (WNW) – It sounds like this apparition of Mercury will be the best one of the year. Just get out after sunset, look WNW, and the first point of light you’ll see is Mercury.  BONUS: On the 2^nd, Mercury will be right next to the Pleiades, with the Moon. Get out some binoculars or a low-power scope to see both of them in the same view.

Throughout the night – None

Morning – Venus, Mars, Jupiter, Saturn (SE)

Let’s use Venus as our guidepost for the month, as it is the most visible object in the morning sky.

• Venus (E) – Keep an eye out after 4:30am, looking E, for the highlight of the spring and summer mornings this year, Venus. About 15˚ above the horizon and hard to miss, the brightest object in the morning sky will blaze as a “morning star”.
• Jupiter (ESE) ­– Jupiter starts May less than 1˚ away from much brighter Venus, then travels 30˚ rightward to finish the month right next to Mars in the SE
• Mars (ESE) – Mars starts May about 15˚ away from Venus, to the right, and travels away to 30˚ from Venus by the end of the month, with Jupiter joining it.
• Saturn (SE) – Saturn starts cautiously leaving the group of morning planets in May, starting less than 20˚ to the right of Mars, and ending up double that distance away.

 

EVENTS

Evening Crescents (look West after Sunset)

First Quarter Moon – 8^th (Visible until midnight)

Evening Gibbous (Mostly lit, after Sunset)

Full Moon – 17^th (Visible all night)

Waning Gibbous (Mostly lit, rises later at night)

Last Quarter Moon – 22^nd (Visible from midnight into the morning)

Morning Crescents (look East in the AM)

New Moon – 30^th (darkest skies)

 

1^st – CONJUNCTION – Jupiter, Venus – Less than 1˚ apart, Jupiter and Venus rise together this morning.  Get out and look low in the East after 4:30am (when they rise) for the brightest object, Venus, with Jupiter barely up and to the right.

2^nd – Close Encounter – Mercury, Pleiades, Moon – Get out just after sunset, with a nice view of the NWN horizon.  The first light in the sky will be Mercury, in its crescent phase, with the Pleiades about 2˚ down and to the right.  Get your binoculars and scopes out!  The Moon can also be your guide, being 4˚ up and to the left of Mercury.

15th – 16th – TOTAL LUNAR ECLIPSE – Sunday night into Monday morning

           Watch the Moon pass through the Earth’s shadow and witness the light from all the sunrises and sunsets on Earth at the same time! No telescope needed for this event! (Though it will certainly make the event even cooler)  Make sure you have a view of the Moon.  For those of us on the east coast, you’ll be looking South about 25˚ above the horizon.  Those nearby trees could get in the way.  Try going out the night before from 10pm to midnight.  The moon will be in a similar direction, but about 5˚ higher on the 14^th.

• Partial Phases starts: 10:28pm EDT – This is when the dark umbra of the Earth’s shadow will start to “eat away” at the Moon.
• Totality Starts – 85 minutes – 11:29pm EDT – This is when the Moon is FULLY in the umbra of the Earth’s shadow.  Only the light that has passed through the Earth’s atmosphere and bent toward the Moon is visible.  The atmosphere scatters the blue, violet, green, and yellow, leaving only the orange and red to reach the moon, similar to what you see during a sunrise or sunset.  Notice that the top of the Moon will be darkest while the bottom will be lightest.
• Greatest eclipse 12:12am – This is when the Moon is as deep in the Earth’s shadow as possible for this eclipse.  Not quite dead center, but about halfway there.
• Totality Ends – 12:54am EDT on the 16th – The Moon leaves the umbra of the Earth’s shadow and is back to be a partial lunar eclipse until…
• Partial phase ends: 1:56am EDT – Eclipse is over! (Technically, it’s in the penumbra of the Earth’s shadow for about another hour, but that’s really hard to detect with the naked eye.

21^st - 27^th – Close Encounter – Moon, Jupiter, Mars, Venus, Saturn – The Moon joins the sunrise planet party this week!  To set the scene, each morning get out between 4:30am and 5am, and you’ll be able to see Venus, with Jupiter to the right about 15˚, Mars to the right of that 5˚, and Saturn about 30˚ even further to the right of Mars.  From left to right, that’s Venus, Jupiter, Mars, Saturn.  What happens over the next week or so is the Moon travels through the lineup.    The Moon is about 15˚ to the right of Saturn on Saturday the 21^st, but moves to about 5˚ below Saturn on Sunday the 22^nd.  Monday morning it’s between Saturn and Mars, and makes a nice triangle with Mars and Jupiter on Tuesday the 24^th.  On the 25^th, The Moon lines up perfectly with a line connecting Mars and Jupiter.  Thursday the 26^th, you’ll have a beautiful crescent Moon less than 10˚ to the right of Venus, and the next morning it switches over to the other side of Venus.

29^th – 30^th – CONJUNCTION – Jupiter, Mars –  Just like early in the month, but this time with Mars, Jupiter is less than 1˚ away from a fellow planet of in the ESE.  This time, though, you can start seeing them after 3am.

 

CONSTELLATIONS

Use a sky map from www.skymaps.com to help you out.

After Dinner, Before Bed:

Leo, Big Dipper, Bootes – 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. 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.

         Quite the exciting month for planets…if you like getting up early.  4 of the 5 visible planets are hanging out together in the mornings, with Mercury having its best apparition for the year in the evenings, along with two conjunctions of morning planets and some possible meteors.

         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 – Mercury (last week or two of April)

• Mercury (WNW) – It sounds like this apparition of Mercury will be the best one of the year. The last two weeks of April it SHOULD be visible, but the 30^th will be the best day, given Mercury will be higher in the sky than ever, and doesn’t set until 9:45pm.  Just get out after sunset, look WNW, and the first point of light you’ll see is Mercury.  BONUS: On the 30^th, Mercury will be right next to the Pleiades.  Get out some binoculars or a low-power scope to see both of them in the same view.

Throughout the night – None

Morning – Venus, Mars, Jupiter, Saturn (SE)

Let’s use Venus as our guidepost for the month, as it is the most visible object in the morning sky.

• Venus (SE) – Keep an eye out after 5am, looking SE, for the highlight of the spring and summer mornings this year, Venus. About 20˚ above the horizon and almost impossible to miss, the brightest object in the morning sky will blaze as a “morning star”.
• Mars (SE) – Mars starts February about 5˚ to the right of Venus, with Saturn nearby as well. Mars is considerably dimmer than Venus, so you’ll have to get out there before dawn starts, when it’s still dark, and look right around Venus for it.  Throughout April, Venus moves away from Mars to be about 15˚ to the right by the 30^th.
• Saturn (SE) – Saturn begins the month in between Mars and Venus, but a little lower. By the 5^th, Saturn passes Mars in its rightward march away from the cluster of planets, and is less than one degree away from Mars. Onward through the month, Saturn continues to move rightward, ending April about 17˚ degrees to the right of Mars.
• Jupiter (SE) ­– Jupiter is coming into its own as a morning planet this month. On April 1^st, it rises after 6am, so it will be low and hard to see in twilight, and far away (25˚ to the left) from the cluster of Venus, Saturn, and Mars.  Each day from there though, it rises earlier and is higher, pretty easily visible by mid-month, when Jupiter, Venus, Mars, and Saturn are lined up and about equally spaced. Venus then closes in on Jupiter, and on April 30^th, the pair are less than 1˚ apart, rise around 5am, and are easily visible.

 

EVENTS

New Moon – 1^st (darkest skies)

Evening Crescents (look West after Sunset)

First Quarter Moon – 9^th (Visible until midnight)

Evening Gibbous (Mostly lit, after Sunset)

Full Moon – 16^th (Visible all night)

Waning Gibbous (Mostly lit, rises later at night)

Last Quarter Moon – 23^rd (Visible from midnight into the morning)

Morning Crescents (look East in the AM)

 

5^th – CONJUNCTION – MARS, SATURN – The first of a couple conjunctions this month, go out early in the morning after about 5am and find Venus (the brightest one). About 7˚ to the right of Venus will be both Mars and Saturn less than half a degree apart.  Them being so close should allow some good telescope opportunities, astrophotos, and a chance to see how differently colored they are, Mars being red, Saturn typically described as light caramel.

22^nd – LYRID METEOR SHOWER – At only 10-20 meteors per hour, it is a minor shower, and we have a Moon washing out the fainter ones starting at 2:30am.  You’ll still be able to see SOME meteors at night, but don’t get too excited.  The shower is greatest on the 22^nd, but you might see some on the 21^st and 23^rd 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)

23^rd - 27^th – Close Encounter – Moon, Jupiter, Mars, Venus, Saturn – The Moon joins the sunrise planet party this week!  To set the scene, each morning get out between 4:30am and 5am, and you’ll be able to see Venus, with Jupiter to the left 6˚, Mars to the right 13˚, and Saturn about 13˚ further to the right.  From left to right, that’s Jupiter, Venus, Mars, Saturn.  What happens over the next week or so is the Moon travels through the lineup.  On the 23^rd, the Moon is 22˚ to the right of Saturn, and then move to only about 10˚ to the right on the 24^th.  On the 25^th, the Moon moves between and below Mars and Saturn, making a nice triangle.  Then it switches dance partners up on the 26^th, moving between and below Venus and Mars.  Finally, on the 27^th the Moon is closest to some planets for this trip, about 5˚ below both Venus and Jupiter. 

30^th – CONJUNCTION – Jupiter, Venus – Only ½˚ apart!  Get out there by 5am at the latest (they rise at 4:30am) and look ESE with a decently low horizon and find the VERY bright Venus with also bright Jupiter less than a pinky-width to the left. Get out that telescope and see both of them in the same view!

30^th – Close Encounter – Mercury, Pleiades – Get out just after sunset, with a nice view of the NWN horizon.  The first light in the sky will be Mercury, in its crescent phase, with the Pleiades about 1˚ to the right.  Get your binoculars and scopes out!

30^th – Partial Solar Eclipse (that you probably won’t see) – Only visible in western South America and the ocean around there.  Check social media for pictures and live streams!

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.
