Upstate NY Stargazing in April: The Lyrid meteor shower

When asked to list the contents of our Solar System, some stop at the Sun, planets, and moons. Others will remember comets – a list of objects that grows much longer every year. For those looking for up-to-date info, see minorplanetcenter.net – we have comfortably cleared the 4000 comet mark. Some may add the asteroid belt – a region between Mars and Jupiter which looks less like the chaotic debris field from "The Empire Strikes Back" and more like oases of larger rocks separated by vast, empty deserts of tiny particles. Don't forget the currently 18,000-long list of NEOs, or Near-Earth Objects.

These are among the more than 18,000 reasons why the late-great Stephen Hawking and others have championed the need for colonization beyond the Earth's surface.

Changing positions in the sky is one thing – changing elevations is very different. Occasional bright flares make the news when captured on video. Events like Tunguska and Chelyabinsk remind us that there thing in space we might miss that could level cities. We are fortunate that most of the roughly 160 tons of debris from space that hits the Earth *each day* is in the form of micrometeorites that you could start collecting with a strong magnet and a flat rooftop.

The highly-anticipated demise of the Tiangong-1 over the weekend was a reminder that we may not be able to always rely on the "dilution-solution" of handling our garbage. Our planet is large, spherical, mostly covered in water, and largely unpopulated – but the number of satellites going to space will only increase as launches get cheaper. It remains to be seen if nations will opt to address the dangers of space junk before or after something serious – and unavoidable – happens here on the ground.

Lectures And Observing Opportunities In Upstate/Central New York

New York has a number of astronomers, astronomy clubs, and observatories that host public sessions throughout the year. Announced sessions from respondent NY astronomy organizations are provided below for April. As wind and cloud cover are always factors when observing, please check the provided contact information and/or email the groups a day-or-so before an announced session, as some groups will also schedule weather-alternate dates.

Lunar Phases

The Moon's increasing brightness as Full Moon approaches washes out fainter stars, random meteors, and other celestial objects – this is bad for most observing, but excellent for new observers, as only the brightest stars (those that mark the major constellations) and planets remain visible for your easy identification. If you've never tried it, the Moon is a wonderful binocular object. The labeled image identifies features easily found with low-power binoculars.

Observing Guides

Items and events listed below assume you're outside and observing most anywhere in New York. The longer you're outside and away from indoor or bright lights, the better your dark adaption will be. If you have to use your smartphone, find a red light app or piece of red acetate, else set your brightness as low as possible.

The sky at 9 p.m. on April 15, accurate all month except for the changing Moon position.

Evening Skies: Observers with bad necks or busy schedules have been waiting all winter for April. The constellations of the Winter Triangle – Canis Major, Canis Minor, and Orion – and additional of the Winter Hexagon – Gemini, Auriga, and Taurus – are finally lower in the western sky after sunset. Binocular viewers have precious little time to take in objects around Taurus and Orion.

This is also our last month to take advantage of Orion as a guide to its local constellations before it disappears again until just before sunrise in early August.

Orion can guide you around its neighborhood. Red = belt stars to Sirius and Canis Major; Orange = Rigel and belt center to Castor and Pollux in Gemini; Yellow = Bellatrix and Betelgeuse to Canis Major; Green = Belt stars to Aldebaran and Taurus; Blue = Saiph and Orion's head to Capella in Auriga. Click for a larger view.

Morning Skies: The observing excitement this month is to the south. Saturn and Mars are putting on an excellent show atop the teapot asterism in Sagittarius, while Jupiter watches from the west in Libra. Hopping from Antares to Jupiter to Spica, try to find the very personable representation of the constellation Virgo, who appears to be falling on her backside on the western horizon this month.

The sky at 5 a.m. on April 15, accurate all month except for the changing Moon position.

Planetary Viewing

Venus: Venus has been an evening delight recently, with early March observers even fitting it and Mercury into the same binocular field of view. Venus continues to set later each day this month, getting brighter throughout.

For bright sightings, Venus has the first half of the month to itself. On the 17th, it pairs with a thin crescent moon after sunset, then spends the next few days sliding right between our two closest star clusters – the Pleiades and Hyades in Taurus. April 28th is the closest grouping of the three, with Venus almost making a straight line with Aldebaran and the Pleiades.

Groupings of Venus, the Moon, Pleiades, and Hyades later this month.

Mercury, Mars, Jupiter and Saturn: Jupiter starts the month rising close to 11 p.m. and finishes the month clearing the horizon at 9 p.m. We'll have Jupiter in our nighttime sky until October, ideal for small telescopes all summer long. As an early marker, the Moon joins Jupiter from above in Libra on April 3rd

The full view of the southern sky on April 3, showing morning pairings of the Moon and Jupiter to the southwest and Mars and Saturn to the southeast.

Those with even poor-quality binoculars are able to see the four bright satellites of Jupiter – known as the "Galilean Moons" for their first observer – and the appearance of Jupiter as a disc of light instead of a simple pinpoint like all stars. Many websites, including the Jupiter's Moons webapp at Sky & Telescope, can provide you with the real-time and future positions of the fast-moving moons for any viewing opportunity you get this and every month.

The best show will be between Mars and Saturn this month. On April 1st, the two are just above the handle of the Sagittarius teapot with Mars on the right. On April 3rd, Mars will be directly below Saturn, an excellent site with or without binoculars. Mars move farther west each night thereafter, buzzing just below distant Pluto on the 26th and 27th. For those still not sure if those two extremely bright pinpoints are Mars and Saturn or not, the Moon provides an obvious marker on the morning of April 7.

The Moon meets Saturn and Mars above the teapot asterism of Sagittarius on April 7. Click for a larger view.

If you scan the area around both planets with binoculars, don't be surprised if you see batches of stars or little fuzzy features that don't come into focus – you're looking into the center – and densest – part of the Milky Way in this direction, where open clusters, globular clusters, and nebulae abound.

Swift Mercury even makes an appearance due east just before 6 a.m. starting in mid-April. If you intend on using binoculars to find it, be sure to stop your search well before sunrise.

ISS Flyovers

Satellite flyovers are commonplace, with several bright passes easily visible per hour in the nighttime sky, yet a thrill to new observers of all ages. Few flyovers compare in brightness or interest to the International Space Station. The flyovers of the football field-sized craft with its massive solar panel arrays and six current occupants can be predicted to within several seconds and take several minutes to complete.

Those looking to figuratively catch the ISS this month have the first 12 days to do so, after which it is gone from our skies until early May. The ISS is an evening target these first two weeks, with several days of double-flyovers all between 8 and 11 p.m.

Meteor Showers: Lyrids – Active April 16 To April 25, Peaking The Morning Of April 22

Meteor showers occur when the Earth passes through the debris field of a comet or asteroid. As these objects approach the warming sun in their long orbits, they leave tiny bits behind – imagine pebbles popping out the back of a large gravel truck on an increasingly bumpy road. In the case of meteor showers, the brilliant streaks you see are due to particles usually no larger than grains of sand. The Earth plows through the swarm of these tiny particles at up-to 12 miles-per-second. High in the upper atmosphere, they burn up due to friction and ionize the air around them, producing long light trails. We can predict the peak observing nights for a meteor shower because we know when and where in Earth's orbit we'll pass through the same part of the Solar System – this yearly periodicity in meteor activity is what let us identify and name meteor showers well before we ever had evidence of what caused them.

The name of each meteor shower is based on the constellation from which the shooting stars appear to radiate – a position in the sky we call the radiant. The Lyrid radiant is precariously close to the funny bone of the troubled Hercules, but is still considered within the official borders of Lyra the Harp. Finding the radiant is as easy as finding the bright star Vega, which rises in the northeast just before 9 p.m. on the active nights of the Lyrids. Those awake during the peak 1 a.m. to 5 a.m. window are treated to the complete Summer Triangle – a reminder that the summer constellations are well on their way.

The Lyrid Meteor Shower radiant, roughly between the bright star Vega and the southern elbow of Hercules. Click for a larger view.

How to observe: The nights leading up to the Lyrid peak will be the best time for viewing this month, as observers on the 23rd and 24th will have to compete with the bright moon to the west. One thing you'll be sure *not* to see this year is the comet producing the Lyrids – Comet Thatcher (C/1861 G1) has a 415-year orbit and was last in our part of the Solar System in 1861, just a bit too early for anyone to even attempt capturing it on a photographic plate.

Learn A Constellation: Gemini

Gemini in the western sky after sunset this month above Orion's Club.

In last month's article, we delved into some of the mathematics that made up the early lunar calendars, noting how much simpler life would be if only the Moon went around the Earth every 30 days and the Earth went around the Sun every 360 days. This month, we go with a full-on mythological possibility.

Venus is bright enough to cast shadows, but is never out for more than a few hours past sunset or a few hours before sunrise – a planet can only be visible all night long if it's beyond our own orbit. Mars, Jupiter, and Saturn are the only three throughout human history that any one of our ancestors could have observed all night long. Of the three, Jupiter is the brightest object, no doubt the reason for its moniker of "king of the planets," its association with Zeus throughout Greek/Roman antiquity, and its attribution to the Babylonian god Marduk long before the Greeks.

Jupiter's orbit is 11.86 years long. That means, nearly every 12 years, Jupiter appears in roughly the same place in the sky from our vantage point on Earth. If one were to believe that the god(s) did not trade in coincidences in the nighttime sky, certainly the 12-year cycle for Jupiter's return to its starting point was something profound – and the division of its path into 12 stations by the Babylonians was simply good bookkeeping to make sure of no confusion when it came to knowing where one's god might be.

Our year-long walk around the zodiac brings us to Gemini the Twins this month. These two have spent at least the last 2,000 years dancing atop Orion's club in their Greek mythological roots, and have had their bright stars Castor and Pollux regarded as celestial twins as far back as Babylonian times. As the eastern-most member of the Winter Hexagon, Pollux and all of Gemini are easy to find and all the more prominent by their placement above Orion and Taurus. Often sketched with hands held, Pollux is all knees-and-feet, while the svelte Castor seems to have had a part of one leg knocked to the other by Orion's club.

M35, off Castor's foot and as wide as the full Moon. The smaller, denser cluster at lower-right is NGC 2158.

Gemini is best known for four observing targets of astronomical or historical significance. Off the western foot of Castor lies the open cluster M35, observable as a fuzzy patch without binoculars under dark skies. Much closer to home, Aristotle mentioned observing Jupiter occulting, or temporarily covering, a star in Gemini way back in December of 337 B.C.E. Much closer to home and recent history, both Uranus (1781) and Pluto (1930) were discovered within the borders of Gemini.

Upstate New York Stargazing – July, 2016

Author's Note: The "Upstate New York Stargazing" series ran on the newyorkupstate.com and syracuse.com websites (and limited use in-print) from 2016 to 2018. For the full list of articles, see the Upstate New York Stargazing page.

Upstate New York has had a rare recent run of some excellent clear nights. Those taking the extra hour past sunset to take in some of the nighttime sky have not been disappointed, with the three bright planets Jupiter, Mars, and Saturn making ideal targets for good binoculars and small telescopes. With the Summer Solstice just past us, amateur astronomers are now adding up the extra minute-or-so of dark sky each evening, while the younger astrophiles (and their parents) are able to return to observing free from worries of sleeping through morning classes with the end of the school year.

July is also the month when the band of our Milky Way galaxy – the original “late night TV” for most of human history, returns in all of its cloud band-like glory to suburban and darker skies during reasonable observing hours (that is, before midnight for most of us).

Your First Steps Outside:

Items and events listed below assume you’re outside and observing between 9:00 p.m. and midnight throughout July anywhere in New York State. The longer you’re outside and away from indoor or bright lights, the better your dark adaption will be. If you have to use your smartphone, find a red light app or piece of red acetate, else set your brightness as low as possible.

The view looking Southwest at 10:00 p.m. on July 15th (except for the changing Moon position, this mid-month view is accurate for all of July). Image made with Stellarium. Click the image for a larger size.

If you walk outside around 9 p.m., you’ll not be able to miss Jupiter beaming bright to the West/Southwest. It will be the first “star” visible after sunset and is easily confused as being a distant plane. Through the first-half of July you’ll be able to find the bright star Regulus in Leo the Lion to Jupiter’s right, then Leo’s tail star Denebola (not as bright as Regulus, but still an easy find) above Jupiter. Sweeping left from Jupiter along the red line above, your first bright stopping point is the star Spica in Virgo. Move your eyes a similar distance to the left to land on the very bright and red-orange Mars, now sitting in Libra the Scales. Mars is second only to Jupiter in brightness right now – if you can see Jupiter before dusk, Mars will also be visible to the South, in which case test your eyes with finding the bright star Spica near their middle. Star hop to the left of Mars and you next land on Antares, a red-orange supergiant that is the heart of Scorpius. Leaving the line above, the planet Saturn lies just above, and brighter than, Antares.

Mars, Jupiter, and Saturn are three of the five “Superior Planets” in our Solar System – which simply means they are on the outside of Earth’s orbit with respect to the Sun (Venus and Mercury then referred to as “Inferior Planets” – and, to temper our planet’s ego, we’re an Inferior Planet to all the Superior Planets). Uranus and Neptune, the remaining two Superior Planets, can be tough catches that require some decently dark skies (and, especially for Neptune, magnification).

ISS And Other Bright Flyovers:

Satellite flyovers are commonplace (several bright passes per hour, dozens hourly once you know what to look for), yet a thrill to new observers of all ages. Few scheduled flyovers compare in brightness or interest to the International Space Station. The flyovers of the football-sized craft with its massive solar panel arrays can be predicted to within several seconds, with these flyovers taking several minutes to complete. The Top-10 brightest July flyovers for Upstate NY (in terms of pre-midnight timing and peak brightness) are listed below (predictions courtesy of heavens-above.com). Due to its orbit, we won’t see pre-midnight flyovers until later this month, then we’ll have many bright flyovers in August. Simply go out a few minutes before the start time, orient yourself, and look for what will first seem like a distant plane (the difference being that satellites don’t have flashing lights at their wingtips – or wingtips, for that matter).

This Month’s Moon:

New Moon – July 5th

First Quarter – July 12th

Full Moon (the Full Buck Moon) – July 19th

Third-Quarter – July 26th

Your first thin Crescent Moon appears close to sunset on July 6th and is in the pre-Midnight sky until July 25nd. The Moon’s increasing brightness as Full Moon approaches washes out fainter stars and celestial objects – this is bad for most observing, but excellent for new observers, as only the brightest stars (those that mark the major constellations) and planets remain visible for your easy identification. If you’ve never tried it, the Moon is a wonderful binocular object.

This Month’s Planets:

Jupiter: The king of the planets lies to the West/Southwest, biting at the hind feet of the constellation Leo the Lion. It is the brightest object in the nighttime sky after the Moon right now and appears early after sunset. Over the next few days, you will hopefully see news and updates about NASA’s Juno Mission as it begins its Jupiter survey on July 4th – we’ve still many questions about this planet despite (and because of) many previous missions.

Through good binoculars, Jupiter is a bright disc circled by its four Galilean Moons (Io, Europa, Ganymede, and Callisto). You can continue the tradition begun by Galileo himself by observing these moons and, over the course of an hour or less, see their positions change even with low-power binoculars.

Mars: We made our closest approach to the bright red-orange Mars in late May and it continues to be prominent in the Southeast/South sky, balanced between the scales of the constellation Libra. Jupiter and Saturn, being much farther away, seem to move very little against the backdrop of stars. Mars, on the other hand, will reduce its distance to the bright star Antares by half from July 1st to 31st. On August 23/24, Mars will delight observers and astrophotographers as it passes between Antares and Saturn.

Saturn: Off to the East of Mars lies Saturn. While currently in the constellation Ophiuchus, you might more easily find it by looking for a bright pair of stars – one of them will be the red-orange star Antares in the constellation Scorpius, and Saturn will be the other bright “star” above it. These two will be a pair for as long as we can see them this year. In good binoculars, Saturn and its rings appear as a small oval. With big binos or a small telescope, you should be able to distinguish between the planet and its rings, and maybe even see the dark Cassini Division within the rings.

Learn A Constellation: Saturn And Antares Take The Sting Out Of Finding Scorpius

If you’re brand new to observing, your quickest route to picking out the constellations is to start bright – working your way from the most easily seen stars down to the dimmer ones, playing celestial connect-the-dots until the mythological characters reveal themselves. Saturn and Scorpius’ heart-star Antares provide a bright pair to your South that will help mark the constellation out. The Rey’s Diagram for Scorpius (just one of many possible representations you might come across that all still contain the hooked tail) is shown below, with shortened claws attempting to pinch Mars to their West, and its curved tail dipping South (likely below the horizon) before curling back up again to the East with the bright stinger star Shaula. If you can make this shape out, consider yourself yet another in a long line of observers who, starting with (at least) the Babylonians, have seen this scorpion in the sky for (at least) 5,000 years.

The view looking South at 10:00 p.m. on July 15th (except for the changing Moon position, this mid-month view is accurate for all of July). Use the bright Mars, Saturn, and Antares to find the rest of Scorpius’ body. Image made with Stellarium. Click the image for a larger size.
