Transcript
- 0:00Howdy stargazers and welcome to this episode of Star Trails.
- 0:11I'm Drew and I'll be your guide to the night sky for the week starting October the 6th
- 0:16to the 12th.
- 0:18This week we'll check out some familiar and some not so familiar deep sky objects.
- 0:23Venus, Jupiter and Saturn are all putting on a show and a meteor shower is also in the forecast.
- 0:30And by the way, did you hear Earth has gained a second moon?
- 0:35We'll check out the lore and features of the constellation Perseus, the Greek hero of myth
- 0:41who's been a key player in some of our recent episodes.
- 0:44And later I'll recommend some great apps to kick start your observations as we make our way into
- 0:50the longer nights of autumn.
- 0:52So grab your observational instrument of choice, a comfortable chair under the night sky and let's get started.
- 1:01This week the moon will transition from a waxing crescent phase to a waxing gibbous phase.
- 1:07By October 10th it will reach the first quarter phase marking the halfway point to the full moon.
- 1:13As the week progresses the moon will continue to grow in brightness reaching the waxing gibbous phase
- 1:19by the week's end.
- 1:21This period is excellent for lunar observation especially with the first quarter phase providing
- 1:27clear views of the moon's craters and shadows while the waxing gibbous phase offers brighter,
- 1:32more expansive views.
- 1:35Elsewhere in the solar system Jupiter continues putting on a show.
- 1:39It rises shortly after sunset and is visible for most of the night in the constellation Aries.
- 1:46It's near opposition meaning it's bright and easy to spot.
- 1:50With a telescope you can observe the planet's cloud bands and its four Galilean moons, EO,
- 1:57Europa, Ganymede and Callisto.
- 2:00Depending on the resolution of your telescope you may be able to catch a unique phenomenon
- 2:05on Jupiter's face.
- 2:07EO's shadow will transit Jupiter beginning around 8 p.m. on October the 9th.
- 2:13If you can stay up later at 2 a.m. on the morning of the 10th you'll see Europa's shadow
- 2:19transit Jupiter as well.
- 2:22These shadow transits happen frequently and Sky and Telescope has a nice online tool for
- 2:28calculating them when they appear.
- 2:31I'll include a link in the show notes.
- 2:34Look towards the southeast after sunset to spot Saturn in the constellation Aquarius.
- 2:40Saturn will be visible through most of the night and with a small telescope you can catch
- 2:44its stunning rings and possibly its largest moon Titan.
- 2:50Mars rises around midnight and is visible in the early morning hours in the eastern sky.
- 2:56You'll spot it near the stars Caster and Pollux in Gemini and its reddish hue makes it easy
- 3:02to identify.
- 3:05Venus will be shining brightly just after sunset low on the western horizon.
- 3:10I've managed to catch it during my evening walks on the past few nights.
- 3:15Uranus can be seen near the Pleiades star cluster in Taurus while Neptune is best viewed
- 3:21earlier in the evening in Aquarius.
- 3:24As always you'll need a good telescope to locate these outer gas giants.
- 3:30Even farther out some familiar deep sky objects are rising higher in the autumn sky.
- 3:35The Owl Cluster NGC457 is a star cluster in Cassiopeia.
- 3:42Also known as the ET cluster its bright stars form a shape that looks like an owl or the
- 3:49famous movie alien.
- 3:52This cluster is easy to spot and it's a perfect target for binoculars.
- 3:57The Pleiades M45 also known as the Seven Sisters is a beautiful open star cluster located in
- 4:05the constellation Taurus.
- 4:07This cluster becomes increasingly prominent as autumn progresses and it's a fantastic
- 4:12target for binoculars which reveal more stars than are visible to the naked eye.
- 4:18For a challenge telescope users can seek the Blue Snowball Nebula NGC 7662.
- 4:27Located in the constellation Andromeda this striking planetary nebula is known for its
- 4:33bright blue appearance resembling a small round snowball.
- 4:38It's relatively easy to spot through small to medium telescopes and with higher magnification
- 4:44you may observe its internal structure.
- 4:47The Nebula is the result of a dying star shedding its outer layers.
- 4:52Don't forget the Draconid Meteor Shower which peaks overnight between October the 8th and
- 4:589th.
- 4:59The Draconids are unique because they're best viewed in the evening not after midnight like
- 5:04many other showers.
- 5:06The meteors will appear to radiate from the constellation Draco but remember you can see
- 5:11them almost anywhere in the night sky.
- 5:21Between last week's annular solar eclipse which sadly was not visible here in North
- 5:26America, seemingly non-stop solar flare blasts, a new comet that could light up the sky next
- 5:34week and the Nova Watch on T Corona borealis that I've mentioned in quite a few episodes,
- 5:41there's been a lot of astronomy in the news lately.
- 5:45Sometimes these headlines just seem a bit sensational.
- 5:49For instance there's been a fair amount of press lately about Earth's new second moon.
- 5:55On September 29th Earth captured a new mini-moon called 2024 PT-5 which will orbit the Earth
- 6:04for about 57 days.
- 6:07But despite the flashy headlines if you expect to see this new moon you're going to be disappointed.
- 6:14Astronomers estimate this object is only about 10 meters wide, about the size of a school
- 6:19bus.
- 6:20I'll leave spotting this one to the professionals.
- 6:24While PT-5 might not be much to look at it does remind us that there's a whole world
- 6:29of quasi-satellites that whip around the Earth thanks to the influence of our planet's gravity
- 6:35on these small objects.
- 6:38We'll talk about some of these in a future episode.
- 6:44A great constellation to explore in October is Perseus which is well positioned in the
- 6:53northeastern sky and offers plenty of interesting stars and deep sky objects.
- 6:59In Greek mythology Perseus is one of the great heroes known for slaying the Gorgon Medusa
- 7:06and rescuing Andromeda from the sea monster Cetus.
- 7:10After his adventures Perseus and Andromeda were placed among the stars along with other
- 7:16characters from his story such as Cassiopeia.
- 7:20The constellation features some perennial deep sky targets including the double cluster
- 7:26NGC 869 and NGC 884.
- 7:32Located on the border between Cassiopeia and Perseus the double cluster is a stunning sight
- 7:37through binoculars.
- 7:39These two open star clusters are packed with young hot stars and they shine brightly against
- 7:45the backdrop of the Milky Way.
- 7:48The California Nebula NGC 1499 is a faint emission nebula visible under dark skies and
- 7:56named for its resemblance to the shape of the state of California.
- 8:01The nebula is located near the bright star Mencar.
- 8:05It's best viewed with long exposure astrophotography due to its faintness.
- 8:11Finally Al Gohl the demon star is one of the most famous variable stars in the sky.
- 8:18It's part of an eclipsing binary system where one star periodically passes in front of the
- 8:23other causing the star to dim and brighten over a 2.8 day cycle.
- 8:30This dimming and brightening can be observed with the naked eye making it one of the few
- 8:35stars where you can directly observe variability.
- 8:44As we head into October the nights are getting longer and clearer which means it's the
- 8:49perfect time to get outside and do some serious stargazing.
- 8:54When I was a kid this meant I had to pull out an atlas of star maps and try to make
- 8:59sense of the sky while trying to read the charts with a red flashlight.
- 9:03I feel very fortunate nowadays as my night sky atlas is on my smartphone.
- 9:10There's a universe of helpful apps and software out there that can make your stargazing experience
- 9:16even better so I wanted to mention a few of these tools that will hopefully help you get
- 9:21more out of your time under the stars.
- 9:25We'll start with the apps you can take with you wherever you go, smartphone apps.
- 9:31Most of these night sky apps make it easy to navigate the sky using some form of augmented
- 9:37reality or motion based tracking.
- 9:40They're also helpful for tracking celestial objects and for finding the best times to
- 9:45observe.
- 9:46You've probably heard me mention on various episodes that cross checking with an app is
- 9:51the best way to ensure that you can see the phenomenon we discuss in your area.
- 9:57There are a couple good ones to try and don't worry there'll be links to all of these resources
- 10:02in the show notes.
- 10:04The first up is Sky Safari, one of the most comprehensive stargazing apps out there.
- 10:11Available on both iOS and Android, Sky Safari lets you point your phone at the sky and instantly
- 10:18identify stars, planets and constellations.
- 10:22You can even simulate what the sky looked like hundreds or thousands of years ago.
- 10:27I know many of the folks in my local astronomy club prefer Sky Safari.
- 10:32It features a massive database of stars, planets and deep sky objects and you can use it to
- 10:38control compatible telescopes which is also nice.
- 10:42The basic app sells for about $5 but there are plus and pro versions that sell for $20
- 10:49and $30 respectively.
- 10:52The basic version is aimed at beginners or casual stargazers.
- 10:56It includes a database of around 120,000 stars, planets and other objects.
- 11:02Sky Safari Plus significantly expands the database to more than 2.5 million stars and
- 11:09includes many more deep sky objects, comets and satellites.
- 11:14It also introduces enhanced features like more advanced telescope control, orbit simulation
- 11:19and detailed observation planning tools.
- 11:23For the most advanced users, there's the pro version with an unimaginable database of more
- 11:29than 100 million stars and millions of galaxies.
- 11:35Pro is designed for seasoned astronomers and astrophotographers who need detailed observation
- 11:41logs and extensive telescope control options.
- 11:46Next up is my app of choice, Stellarium Mobile which is another highly rated app for iOS and
- 11:52Android.
- 11:53Stellarium is known for its clean, intuitive interface that mimics a real-time sky view.
- 12:00Stellarium tends to be more accessible for casual users or those who prefer a more visually
- 12:06immersive experience without the need for advanced customization.
- 12:11It does have some telescope control and a host of other nice features but it's not nearly
- 12:16as full-featured as Sky Safari.
- 12:19Even so, I've been a fan of Stellarium since its early days when it was a free open-source
- 12:25desktop app.
- 12:27The base mobile app is free and paying $20 gets you some additional tools to help you
- 12:32plan your observations.
- 12:34You can also use Stellarium on the desktop or in a web browser for free and we'll talk
- 12:40about that in a moment.
- 12:42Here's one more app to consider, Starwalk 2.
- 12:46Like Sky Safari and Stellarium, Starwalk is like having a planetarium in your pocket.
- 12:53Available on iOS and Android, this app uses augmented reality to give you an immersive
- 12:58view of the night sky.
- 13:01Compared to the other apps, Starwalk 2 is even more beginner-focused and leans more
- 13:05into accessibility and ease of use.
- 13:08It lacks some of the in-depth tools but provides a visually appealing, easy-to-understand sky
- 13:14view that works well for quick lookups and educational purposes.
- 13:19There's an ad-supported free version but upgrades and add-ons are only around $3.
- 13:27These three apps are all similar so you may want to download each one and see which one
- 13:32speaks to you.
- 13:33I'd also like to mention two smartphone apps that both deal with astrophotography.
- 13:40Photo Pills is an app that lets you plan your shots by predicting where the Milky Way, Moon,
- 13:46or specific stars will be at any given time.
- 13:50It includes a calculator for finding the best times and angles for photography and a set
- 13:55of tools for calculating exposure times.
- 13:59Even if you're not an astrophotographer, the sky planning features can really help you
- 14:03understand celestial movements better.
- 14:07If you want to dip your toe into the world of astrophotography and you don't have a photography
- 14:12rig, you might enjoy playing with night cap camera.
- 14:17This app is limited to iOS but many phones now have a night or astronomy mode built in
- 14:22so you may not even need this app.
- 14:25And before you scoff at using a phone for astrophotography, you should try it and see
- 14:30what happens.
- 14:32Using a Google Pixel phone, I caught Andromeda one evening and I've shot Aurora with my iPhone.
- 14:40Night cap camera offers up some features for capturing star fields, meteors, and even the
- 14:45International Space Station.
- 14:48Don't forget a tripod.
- 14:50Now for those of you who like to do a little research and planning before you head outside,
- 14:54there are a couple great desktop programs worth mentioning.
- 14:58First up is the desktop version of Stellarium which is free and open source.
- 15:04Like the phone app, you can simulate the night sky from any location on Earth and see what
- 15:09it will look like at any time or day.
- 15:12Another great option for the desktop is Starry Night.
- 15:15This one is a bit more polished than Stellarium with a highly accurate star map and some extra
- 15:21telescope connectivity.
- 15:23And finally, before we wrap up, there are a couple websites I recommend you check out
- 15:28if you want to stay up to date with celestial events or track satellites and other sky phenomena.
- 15:35HeavensAbove.com is my go-to for tracking satellites like the ISS, Iridium flares, and
- 15:42more.
- 15:43We use this site to generate the sky maps featured on the StarTrails website each week.
- 15:49This site is also popular for amateur radio operators who are trying to bounce a signal
- 15:54off of one of the numerous Hamsats floating around up there.
- 15:59And finally, with all the solar flare activity we've been having lately, I've been checking
- 16:03in frequently over at SpaceWeather.com.
- 16:08This site keeps you updated on solar activity, auroras, meteor showers, and other sky events.
- 16:15It's a great resource if you're looking to catch something like a solar storm or the
- 16:19northern lights.
- 16:21There are a lot more applications and sites that are useful for astronomy and will probably
- 16:25cover more in future episodes.
- 16:28Hopefully, these help kick your stargazing into high gear as clear evenings and longer
- 16:33nights await us.
- 16:37That's it for today's episode of StarTrails.
- 16:40If you found this episode useful, please share it with a friend.
- 16:44The easiest way to do that is by visiting our website, startrails.show, where you can
- 16:50find all of our episodes including transcripts, night sky maps, and more.
- 16:56Until next time, keep looking up and exploring the night sky.
