Aside from being the brightest star visible from earth, it is also the 4th brightest natural object in our night sky, after the moon, Venus, and Jupiter.
“Dog day afternoon” comes from the ancient Roman belief that very hot summer days were due to the added influence of the Dog Star.
Sirius is my favorite star. Love how it shines with an electric blue ting.
It's blue, because of the Doppler Effect,,it was red when moving away from us,,but it's really white,,so this is where you get the red,white and blue from, literally everywhere.Alsi the red and blue in politics parties,and Masonic lodges.
Excellent, simple and informative video! Thanks for the tips!
I have started learning about the stars names from your teaching. Thank you.
Can't imagine a better guide to the stars series. Mahalo!
You have been systematically programmed to INSTANTANEOUSLY believe, memorize and regurgitate everything that scientism tells you!!
I love to hear your explanations of stars.
Interpretation? You instantly believe, memorize and regurgitate everything that scientism tells you!!
This video was siriusly interesting
It’s actually a three star system, with a recently discovered small third star which was predicted by the African Dogon tribe who claimed they were visited by Aliens from that third star which they call the pebble.
Hiroshi LOVES the DOG STAR! ❤
I love looking at the night sky. My only regret is I've always lived in or near a city so most of the sky is washed out. Still as a child if I could see the stars I never felt alone. Thank you for grouping all of the important stellar information in each video AND not just mentioning things like "Class" but giving a quick explanation. It is frustrating watching videos where the speaker uses technical jargon forgetting he is speaking to the general public not third year undergraduates. Kudos to you. I've been adrift in KZhead looking for well made interesting technical videos. Who knew I'd find ones speaking to my heart. And here I was about to let go of my 130mm reflector. There it sits but feet from me aimed up. Where's the duster and lens cleaner?
I'm glad these videos help. I am not an astronomer by trade (I have a biology degree), so I'm learning right along with everyone on this channel. Even thought I don't study the sky as a professional astronomer, I can still appreciate all the work they do, which helps us all gain a better understanding of what's out there. I hope you get the chance observe away from city lights...seeing a brilliant night sky is truly one of nature's best gifts.
Sirius has another significance. It IS the beginning of our western New Year. On the night of the New Year,, Dec31/Jan 1 At precisely midnight,, the dropping of the ball in Times Square, Sirius is exactly south on the meridian. It IS what was determined to be the start of the New Year.
Thank you for this! I noticed it shimmering brilliantly tonight and looked this video up to see what star it was. So cool!
Yet the earth is Flat and STATIONARY
Love this content!! Thanks
Really helpful interesting and informative. Thanks for all your work Janine.
Nice content by Janine as always
Beautiful and brilliant ending. Stellar!
Thank you for the video
Thank you!
Excellent video and great channel. Thanks for doing this. I am subscribed and sharing with friends.
Wow, I love your explanation you are amazing❤
Fantastic video thank you
This was a great video! Well done! ❤
Yes! Isn't CGI ANIMATION just great?!
I saw it yesterday the sky was very clear and I recognize it thanks to you
Ciekawie przedstawione informacje . Super . Pozdrawiam 😉👍
Nice voice. Just subscribed.
This presentation is pretty good 👍
great video
I have a difficult job seeing Sirius B due to the glare from the A star. It needs excellent seeing conditions and transparency. The drawing you showed, showed very different size comparisons compared to the photo from Hubble.
Nice information
Thank you for making these videos! Finding my way with a 10 inch dob.
Thanks!
Thank you
At 1:50, is that size comparison between the two stars right? Looks to me like you have Sirius B way too big in comparison to Sirius A. Wikipedia has Sirius at 1.7x the diameter of the Sun, while Sirius B is 0.008x the Sun's diameter. The Hubble image isn't representative of the actual diameters of the two objects, but it's a closer match to the Wikipedia numbers.
"Shirley, you can't be SIRIUS!"
I've managed to split Sirius A and B with my 8" SCT; it depends on Sirius B's position relative to A and how good the seeing is. I got lucky on both.
Thanks a lot
Thank U so much ❤👍🌹
The Major star systems!❤
Thanks :-)
Looking up from southeast asia we call it the morning star. It rise early morning. As I grew up in Cambodia I never a had a chance to see it cus I usually woke up when the sunrise 🙃
thank you - that is great - I love to observe the sky day or night. And about 6 years ago whien I moved to our present home first in 2015 I got to know Venus. Later I moved to ground flat and I am able to see Orion and more. Since 2018 Iam having less time to sleep because I am looking out of the window. Unfortunately a lot of light of the street and houses. but the worst thing . every big event - clouds on the sky or like tonight it is raining . but I wont complain, I love to learn about our stars - and planets too. See you - next stop how to find the planets in the night sky, good night, regards Crissy
Realy I like this video so so much like you can imagine
Interesting 😊
Nice.
good info and presentation...Winter Triangle ? please and thank you
I loved the video, and I like getting to hear the correct pronunciation for the celestial objects, but you slipped up at 7:12 and called it Beetlejuice. 😂
Damn i always thought its a drone because i could swear sirius is shining in different colours.
Pls we will be looking forward to the the mythologies associated with this star.
Sirius A is expected to have a rather short lifespan. One might wonder when to expect it to go nova. One might also guess that Sirius B has already gone nova. If it were to accumulate a total of 1.4 times the mass of our sun, it will go supernova. Good chance for a double banger sometime soon.
Nice video, i love this channel! The size comparison between Sirius A and B at 2:00 is way off! If Sirius B is 0.0084 times the radius of the Sun, it is around 0.005 times the radius of Sirius A. It should be represented as a small dot next to the much larger Sirius A, much like in that Hubble image.
I agree, the diagram is not size accurate. I’ll rework it for next vid on Sirius.
Useful mnemonic for the 10 brightest stars in the sky: Son: Sir Can Rig A VCR, PA? Sun Sirius Canopus Rigil Kentaurus Arcturus Vega Capella Rigel Procyon Archenar
I honor my deceased dog Una each night I can see Sirius. It is her star and seeing it lets me know she is still with me in spirit and in my heart!
You mentioned that Sirius B is not visible to the naced eye but is it through a telescope? What magnification / aperture would you need to split them?
I haven't seen Sirius yet at the back end of 2023 but obviously saw it earlier in the year.About a week ago I was out camping and caught Orion and Procyon but dawn struck just before Sirius got over the horizon.I always find the Robert, think that was his first name, Temple, definitely his surname,book the Sirius Mystery interesting .He claimed that the Dogon tribe of Mali had a knowledge of Sirius B....but when examined it's all pretty much nonsense!
I started seeing it in the early morning when I wake up, and I couldn’t resist making a video on it.
Super viewing right now in pa.
I've have been looking at it the last 3 nights with clear skies
What about the planets full of wolfen Annunaki?
On a slightly different note: I swear I saw Betelguesue or another nearby star to Orion move or flash on a recent night. Anyone else see it.
From what I see at 3:50, I can say that, the image at 2:00 is not to scale. Is this correct?
Interesting
Could you make a video for Fomalhaut? Thanks
Yes, I have one in the works.
I am one Sirius lap and a bit more old
🙌💖!
Density of SiriusB?
What about Procyon which is Canis Minor at 0.4 magnitude and can easily be seen above Sirius ? Your info is incorrect I believe !
👍👍
👌
Do you think nasa will land a person on serious?
I think I have seen it today, location Turkey
Canis Major one bigest star in all space
SIRIUS, A.K.A ALFA Canis Majoris brightest APPARENTLY but NOT ABSOLUTELY!
Any planets?
Planets have not been detected so far in this system.
i think there are brighter stars than Sirus which can only be viewed from the southern hemisphere.
Only CANOPUS but not brighter than SIRIUS which is by far brightest for both the hemispheres. Then there is the THIRD brightest ALFA CENTAURI A, ,B and C (a.k.a ,respectively RIGIL KENTAURUS and TOLIMAN and PROXIMA the nearest star ) a TRIPLE star system
You their i got a question?
I'm here. What's up?
I am sirious
This is the 59th comment!
Is the 50 yr. Cycle by chance on the same 50 yr. Cycle of the Jewish year of jubilee?
I am not sure.
I thank the internet for the resurgence of the truth that allows me to now see,,, through all the theory and CGI ANIMATION! Let's all thank the mighty Flat earth phenomenon!! Go.
Anybody can draw anything Thats not true it doesnt called dog Only recently And no not A neither b will replace the sun Its just that sirius A only appears on a big sign in a diffrent timing . And they all done ...
i'd love this vid if I could withstand the valley gurl accent
It’s called an east coast PA accent.
you''re right. I was in a bad mood and I'm sorry. I'm from Philly!@@learnthesky
@@jackmurphy687 It's OK. I appreciate you writing back. Some days I get snarky when I don't have a good day as well. I'm glad you responded...I grew up 1.5 hours north of Philly! Go Eagles!
THE SUN IS WHITE ALSO NOBODY TELLS THE TRUTH SMH IM KEEP LISTENING
Are you Sirius?
Nobody will tell that truth
SUN category ORANGE?YELLOW (surface temp arround 5 to 6000 and SIRIUS is of of course WHIITE (around 20,000 C)
