Meteor shower, Orionids, Full moon, Meteoroid, 2021 Skygazing – October 2021

We hope you and yours are doing well as we enter october. This is the 10th month of the year 2021. Where has the year gone already, thank you for taking time out of your busy day to join us right here on earth. Sign education, as always, my name is mike. If you are new to the channel, please be sure to click that subscribe button ring the notification bell. This way, you wont miss out on any of our live streams or any other video uploads in the future. In this show, we are going to talk about the moon phases for the month of october 2021, the planets that are visible without the need of a telescope, a spotlight on some of the cool deep sky objects that you can see around the big dipper that stuff You will need a telescope for and an october meteor shower, theres, actually, two of them, so theres meteor showers this month with all that said, lets get to it, as always, were going to begin with our closest celestial companion, the moon, the moon phases for the month Of october 2021 occur on the following dates: the new moon will be on october, 6th, the first quarter, moon october 13th, full moon, the hunters moon will be october, 20th and third quarter. Moon will be on october 28th of the eight planets of our solar system. Yes, unfortunately, pluto is still demoted to dwarf planet. There are five planets you can see without the need of a telescope in the nighttime sky.

Sometimes you can even see them in the daytime, but thats pretty rare, depending on their position in their orbit and, of course, the earths position in its orbit. You may or may not even be able to see them at all. So lets talk a little bit about where the planets are in the sky. For october 2021., all right were going to go ahead and begin with. The innermost planet were talking about the planet. Mercury mercury has drifted into our morning sky. From our point of view, and on the 25th of october, just before sunrise, you will see mercury very close to the eastern horizon in the constellation virgo thats actually going to be the highest it can be in the morning sky. All right now switch to looking at the sky on the 29th of october were now looking west southwest actually and youre going to see the planet venus very brightly in this guy youve seen venus all month. At least you should have if youve been listening to our shows before venus again is a southwest in the southwest sky, and it is right between the constellations, scorpius, sagittarius and actually ophiuchus, as well. All part of the zodiac constellation set, oh fucus, of course, thats. The 13th zodiac constellation, which is or is not a zodiac constellation depending on who you talk to. Nonetheless, you see the planet, venus very, very bright in the nighttime sky, itll be the highest. It can be in the nighttime sky on the 29th, so hopefully youll have a nice clear sky to see it from your point of view, okay, we are going to jump ahead and skip the planet mars because well mars, as you probably heard us before in other Some of our other shows mars isnt going to be visible until november, and so we get to skip it.

Sorry, jumping over to jupiter and saturn again theyve been tracking across the sky throughout the last few months. Believe it or not. Here we see on the 13th, 14th and 15th, the moon will be right below each of them, making a triangle in its own way. This is the 13th and you have the moon just below saturn again, this is south south east. From your point of view, saturn will be the dimmer of these two planetary objects in the sky. Saturn will have kind of a yellow glow to it, but itll be much dimmer than the bright white glow of jupiter. On the 13th youll have the moon right below saturn on the 14th, the moon will be between the two planets and the 15th. The moon will be much closer, actually past uh the planet. Jupiter again, you can make a triangle between all three of these objects. In the sky, all right for this months, spotlight were going to do something a little bit differently. Normally, we do stuff that you dont need a telescope to see this one. You will, or at least be able to use an online observatory to find some of these objects. When we talk about the deep sky objects around the big dipper, now the big dipper thats, what you call it here in the united states and in canada a lot of places around the world, some places call it the plow like the uk and ireland.

This is an asterism that consists of seven bright stars, three stars making up a tail and four stars making up a cup now an asterism is not a constellation. Lets bring up the constellations and their parts of the sky. There we go youll see the big dipper is the four stars here: making up the stomach and then a tail attached to the big bear known as ursa major. The flip side is the little dipper its way up here. Thats ursa minor, actually is the full little dipper use. These final two stars right here draw a line through them and they will point you to polaris. This is the north star. The pole star, the loud star in the nighttime sky were gon na target near the three tail stars of the big dipper were gon na, be using these three stars as assistants for finding these things now the stars themselves actually have names. This is alioth and then mizar and then alcade is the tail star of the big dipper believe it or not. If you have really good eyes, youll actually see that mizar has a companion star named alcor, just above it do you have to have pretty good eyes or a good set of binoculars to see that extra star there. So i guess technically theres four stars here lets not worry too much about that, but i didnt want to mention it so lets target our tail star. This is alkade and were going to draw a line straight down from it.

If youre able to stick your arm up and stick your hand out, put three fingers below alcate this last star right here and youll notice, theres a little fuzz ball in the sky, as you zoom in zoom in zoom, in zoom in, were gon na end up Right here, and actually were gon na well stop right here and uh well in post, well put a much better image than this. This is where you find the whirlpool galaxy. This is the 51st object on the messier catalog. This is the whirlpool galaxy, a spiral. Galaxy 31 million light years away from our planet earth. The whirlpool galaxy was discovered on october 13th, 1773 by french astronomer, charles messier, who was originally a comet hunter. He ended up making a list of objects which we now call the messier catalog, which were interesting objects, but they were not comets in the sky. They seemed to be constant, so it kind of made note so people could look for comets and ignore these objects. Oddly enough, messiers catalog eventually grew to ‘ galaxies, four planetary, nebulae uh, seven different types of nebulae on top of that and 55 star clusters. If you want to learn more about those, we actually are going to be making a video about the messier catalog, and actually we do talk about messier objects during our live stream, so make sure to again like subscribe and catch one of our live streams. When we do have a chance to do them more, recent research has revealed that the galaxy thats behind it, the elliptical galaxy you see off on the right here.

Its actually got stars gas and dust thats being dragged out of the spiral galaxy towards the elliptical galaxy behind it. So in three dimensions this is actually getting pulled away from us, kinda cool returning to our big dipper in the sky. We again target alcade the tail star of the dipper, well draw a line between alcade and mizar alcor as well, and were gon na stop right in the middle were gon na head straight up from this midpoint about the same distance. We did for the whirlpool galaxy, but this time were gon na go a little bit further. A little bit more were tucking four fingers in this guy, instead of three, so its not much more, but still just a little bit higher up. Here you see a different spiral: galaxy were gon na put again a better picture up here in just a second, but there it is theres actually another one. In the background, this right here is the pinwheel galaxy known as messier number 101. This is a face on spiral: galaxy hes, looking right at it open faced 21 million light years away. All right, finally, were gon na stop once again with our tail of the dipper alcade is our friend for the day and were gon na draw a line up towards draco. Just like that, zoom back out, you can kind of see draco. The dragon constellation goes between the big and little dipper areas. The little dipper once again is ursa minor.

The lit the big dipper is actually just a portion of ursa major, the big bear. Nonetheless, you see we connected two stars right up here in draco. Lets actually go and investigate that, shall we, just above this lower star, were gon na zoom in and see something really really cool right there. Okay lets go ahead and put up a much better image than this. Our final stop for octobers, deep sky near the big dipper is this. This is what is known as the draco trio. This trio is made of three different galaxies. Hence trio, these are not in messiers catalog, but they are in a different catalog. That catalog is known as the new general catalogue of nebulae and clusters of stars, and they abbreviated ngc from top to bottom weve, got ngc 5985 kind of a boring name, i guess but thats what they call it. Thats this face on spiral galaxy its an sbb class weve got a elliptical galaxy in the middle, its a class e3 elliptical that is ngc 5980 and then at the bottom. We have an edge on spiral. Galaxy another sb spiral galaxy. This is ngc 5981. The three galaxies are between 100 and 140 million light years from the planet earth. The big dipper will continue to dip towards the horizon as the evenings progressed throughout the entire month. So youll probably want to get your chance in to see messier 51. The whirlpool galaxy as soon as you can you dont want to let it get too too low because you wont have much time to see it after the sun sets.

Nonetheless, there they are the three objects you want to talk about in this deep sky near the big dipper, as weve talked about in previous shows. A meteor shower is a celestial event in which many meteors are observed to radiate, originate from a point in the sky. Named for the constellation from which they appear to radiate from in october, weve got two meteor showers. One of them is called the draconid or draconid a meteor shower constellation draco, the dragon. The other is the orionid meteor shower constellation orion, the draconids again emanating from the constellation draco. The dragon is a minor meteor shower, for the most part, likely will produce about 10 meteors per hour. So not all that many in the sky, its produced from dust grains, left behind from a comet known as 21p giacobini zener, was first discovered in 1900. The draconids are an unusual shower in the fact that its best viewed in the early morning, instead of the evening, like other meteor showers, the shower usually runs between october 6th and october 10th peaks on the 7th. But you know there is a little bit of leeway. So you can see a few uh before the 6 and youll see a few after the 10th as well. So you have a few evenings to give it a shot. The moon will be a new phase, so these meteors should be a little bit easier to see. Moving forward in time were going to talk about the orionids.

The orionids, of course, will be emanating from the constellation known as orion the hunter, its usually one of the easiest constellations to find three stars making a belt a bright knee star named rigel, a shoulder star named beetlejuice or bethel geese ive heard it pronounced both ways. Most people like to pronounce it betelgeuse, of course, theres orion in the sky, youll, see just above what his club would be see a little marking for the orion its right over here. This is an average meteor shower producing about 20 meteors per hour at its peak. Interestingly, these meteors come from dust grains left behind from a comet. A lot of people know the comet known as halleys comets its been observed since ancient times, halleys comets been around for a very long time. The meteor shower the orionids uh run from october, 2nd all the way through november. 7Th. So well probably talk about this again next month, but the peak is this month. The peak is the night of october 21st and the morning of october 22nd. The bigger issue is, if you want to look at the orionids this year, you have to compete with the full moon. That means that only the brightest of the meteors are going to be seen and with that we come to the end of our brief sky gazing overview for october 2021. In this episode, we talked about the moon phases for the month of october 2021 talked about where the planets are that are visible without a telescope.

We talked about some cool deep sky objects that you do need a telescope to see all near the big dipper in the sky, and we talked about two meteor showers, the draconids and the orionids.
