Videos by Brady Haran
One thing I've learned from drawing plans in architecture is to always include a little sillhouette of a human (to scale) so I get an idea of the size of the spaces I'm making. If I were observing the sun, I would put a little paper circle on the screen somewhere representing the Earth to get an idea of how big these events are. It helps a lot
I really like the way you show, not just the actual astronomy, but also the kit and the physical process, and also the making of the programme. It's kinda inclusive and fun. And horray for Pebbles, The Astro Cat! (more cats in your videos please) :)))
Hooray for Pebbles! Also, cool to see how you can observe the sun w/a telescope!
These old videos, from well before I was aware of the channel or Brady’s work, are just amazing!
Please do more sun videos with Astronomer Pete :)
wow... this is cool. I love sun-astronomy. And the pics of it amaze me every time.
Galaxys and supernovas may be pretty nice... But this little yellow star is my favorite.
Thank you for the introduction.
Hi, Pebbles!
3:07
COOL!
It peeves me that we never get to see these things in real time. This is a treat!
6:48
Yes! This is called "Feedback". watching a picture can turn something into an abstraction very easily. But when we connect the picture with real time sensation perceived thru the other senses of our body, we learn in a different way than with an abstraction alone. This is very important and also difficult with astronomy.
hey glad to have you! you've got some catching up to do!
So good. Between sixty symbols, deep sky videos, numberphile and periodic videos who needs cable? Thanks for all the great videos, keep up the fantastic work!
happy to oblige
thanx for sharing
So much fun to watch this, because it‘s so direct and honest, not smoothed to perfection! Thanks 🤩!
Solar is my favorite type of observing. Great video! Scott
this was pretty awesome. the 11 people that "thumbs down" this video must not like cats.
There are loads and loads and loads of interesting objects in the universe, but for me, our very own sun is the most interesting. Thank you for doing this video, I really hope you do more videos about our sun, not only about watching it, but about facts regarding our sun too!
very glad to hear it!
Great videos, thanks for sharing.
That was fantastic. What a great set-up.
For some reason I thought that Refractors had gone out of fashion.
As far as connecting the telescope iamges with the real sun goes- There was a big complex of sunspots, 7 or 8 years ago, and I noticed you could catch glimpses of something out of the corner of your eye- as if a bird or a plane had just passed in front of the sun, but it would happen all day. It really gave me a sense that the pictures from SOHO and Mt Wilson were from -that- sun up there.
it's been a month. please post another awesome video
Fascinating, thanks for sharing your knowledge and your passion.
one of my favorite deep sky videos yet. Thanks Brady and Pete!
A MA ZING
Even though I've seen hundreds of pictures like this - being able to see it "live" is crazy fun.
That's a good one!!! I had the luck to observe the sun through a telescope like that (not through a computer, but directly into it) during the Venus transit event, it was really cool! We saw Venus of course, but also sun spots, the faint blue color around the corona, and I DID feel the connection you're talking about Brady! After all, we're all stardust, and the sun formed out of the same cloud of cold gas that ultimately collapsed and formed the solar system, and eventually "us"!
Your videos are exactly what I want to see in my subscription after long day at school.
When I saw isle of man on the Hydrogen alpha filter I was very confused because I live on the island and I was even aware that we had a technical optics centre here.
Thanks Brady for this :D
Every Sunday, Universe Today hosts a virtual star party where a few amateur astronomers come together on a Google & RUclips Hangout and use their setups to take and show pictures of various astro-phenomena. There's usually an astronomer or two that'll also have live video of the moon or other planets going on during it and they'll often take requests. If you're interested in watching then hit them up on UniverseToday on Google+ or their RUclips channel of the same name.
:D That looks really cool. Nice thing about the sun is that it is so close - in astronomical dimensions, that is... Very impressive.
Also - very cute cat ^^
Yes, of course :) what I meant was whether or not you could see anything actually moving on the surface of the sun, or if you'd have to speed up a video of it in order to see anything move..?
Years ago I used to take a pair of binoculars, cover one lens and duct tape them loosely to a windowsill, focusing the image on a white card to watch the sunspots. The loose duct tape allowed me to move the binoculars just enough to keep the sun in the center of the card.
Wow!!!!!......... this was something interesting ......... i also want to have that telescope ........
I learn more from your channels than I do in Science at school! Thanks Brady!
i feel like a noob, i just found out about all these awsome channels from the nubmerphille's last video
go brady :) awsome stuff on your channels
i love watching your videos and learning stuff ;)
thank you
Man this is awesome. I got quite recently into the science of the sun. And i have to say its amazing. Though i dont understand most of it yet :D But our star is damn beautiful.
Im waiting for the next video Brady :)
new vids on the way!
The cat was my favourite part.
Pebbles the "Astro Cat" :-)
it's amazing to get a hands-on view like this. magnificent work, as always)
Lovely work, thank you.
Phil Plait and Bad Astronomy got me here, love the vids!
Pebbles the Astro cat!
That so needs to be a Saturday morning cartoon!
When you observe the sun, it is not 'immediate', there is a delay of 8 minutes, or 7 and some change. So if you see the "spike" start to take place then you have time, somewhat to everything ready.
Mind-blowing
Hi Brady, I was wondering if you posted the Part 2 already ?
I am currently trying to understand how to better observe the sun, with binoculars and I also joined a astronomy club where they have couple of scopes to look at the sun.
Thanks for your videos, we love them all !!!
Cats are so great. They like to be with you but most of the time they don't bother you at all. They're like "Hey pal! Pointing that weird thing at the sun again? Cool. I'll just chill with you for a while."
Cute cat.
Brilliant!
Hi great vid Pete is a great astro photo
Notice that H-alpha light comes from a hydrogen atom, not an ion. That means we have an image of an excited, but non-ionized population of hydrogen. The source of ionized hydrogen (protons) comes from hotter regions below, hence proton+electron recombination is occurring in the observed region. Local thermodynamic equilibrium arguments, I believe, show that H-alpha intensity is actually proportional to the recombination rate. Interesting stuff. Corrections? Experts? comment pls.
you'll get more soon!
Amazing!
Brady you missed a trick there- you very nearly made this video the exact same length of time as light travelling from the sun to the earth!!! I know you sometimes do that with the length of your videos :D
this is just awesume
Can anyone tell me what camera and or program on the laptop he is using. i've been looking for a nice camera for beginner astrophotography and i really like the look of the software he's using as well as the camera.
Not sure but it looks expensive :)
Very nice video and interesting video, I am looking forward for the part 2.
However, I wish it could be in HD format. Brady could you fix that ? :)
Thanks!!!
Wow, coincidence - you post a video about Solar telescopes on the day I organised a Solar telescope for the upcoming Solar eclipse. They are pretty awesome pieces of kit.
That was awesome!!!thanks for the video
You guys should come have a go with the Telescope we have at the University of Kent!
Cool stuff!
Nice one chaps; I'll take all the 'practical astronomy' advice I can get hold of! ;)
I just use solar filter paper on the end of my reflector scope. I get a good look at sunspots, but without a H-Alpha filter I can't see much else.
So cool guys
amazing
Awesome video, keep 'em coming, please! A criticism - filming a laptop monitor with a camera really doesn't work very well if the laptop screen contains complex or detailed visuals; also - glare. There are ways of capturing the video output of a laptop which could be edited into your video easily. Cheers!
I enjoy looking at the sun with my 6" reflector and a basic filter, which gives only enough resolution to distinguish sunspots, and no prominences nor mottling. Your observations are fascinating. Two questions: do you lose much resolution with that smallish-looking sensor attached to the end of the scope? Can similar results be achieved using only a neutral density filter and computer software filtering?
Pete images the moon regularly - follow him on Twitter for some real treats in that department!
More i want more!!!!!!!!!!!!
Not only does the sun rotate, but because it's make of gas, different parts of it rotate at different speeds. This action is indirectly responsible for sun spots. Some people think that sun spots have a small impact on the earth. That's the only way the rotation of the sun would affect us.
great info..ty
End on a cheery note.
3:29 Excellent .
Interesting that the poles of the sun and its equater rotate at different rates
I loved pointing my telescope at the sun with no filter and put a white sheet behind the scope and you can see the sunspots like a big hologram
you would be correct due to the time it takes for the brain to process visual and sound stimuli.
Excellent video, thanks (:
I do look at stars (when I can) but do not have my own telescope (yet).
pebbles is beautiful!
we'll try!
tell your friends about us - that'll help! ;)
1:53 to see the cat
I recently seen videos about electric sun model. How it explains for example presence of sun corona and why is it hotter than sun surface. Brady can you ask professors what they think about it and maybe made video? Thanks in advance.
I used my telescope and pointed it at the sun and let it project onto the white wall behind me and it was amazing. I actually saw a sunspot and went to NASA's live footage of the sun and I saw that it was a real sunspot.
Yes, it's true. Amatuers can show that NASA isn't lying with their SDO images. They always EXACTLY match the views i get when the Sun is out here.
Still waiting for my cheque from the Illuminati though. LOL
I want all those filters and an astrocat! XD
Hello pebbles 💚⭐️😸
What you're looking at isn't "live" as he commented. When looking at the sun, you're seeing the sun as it was eight minutes ago.
If you want to be like that, then nothing is "live". Anyway I believe it is still "live" though, because of how relativity works and 4D space-time. Spaces travel through time (usually forward), and time travels through space (all directions). We can't have one without the other, so we have to include all 4 dimensions. So it is live (the time) at our location (the space). But it is 8 minutes in the past (the time) @92 million miles away (the space). Both scenarios exist at once. It's hard to explain but I tried. It's live here, and 8 minutes in the past at the sun.
And the heat you feel on your head while looking at the sun is also 8 mins old, so it's live in that respect; what you see on the screen and feel on your face are synced. Any image of the sun is as live as a livestream with an 8 min delay to prevent stream sniping.
its only about the angle how you view things, every person sees that (and everything else in life and universe) and understands that differently, but it doesnt mean that someone is not right here. you are both right. cheers.
alltime10s sent me here. Pete, I wish your site worked properly in Chrome :( Can't see half the galleries without switching to Aurora. Awesome pics tho!
I feel the same way!
Brady more numberphiles too pls :)
Well, most live things on TV are tape delayed as well.
You've got some great videos here! Do you ever use a fig rig? I need help with a new product I have for filming. Take a look at it. Wondering if you can let me know if you like it and help spread the word.
great video! I need to get a new filter my self would you confirm for me that the sun never changes in relative size? really would appreciate your feed back!
it would be interesting to know about size too, actually i never thought about that :O
Maybe you ask on twitter or so? He did not upload this video, so maybe he never read your question?
Yes the Sun does change apparent size throughout the year. We are closest in January, and farthest away in July. I know that doesn't sound quite right, but it's true. I used to have a setup that could view the whole disk, but only during Summer. In Winter the poles were always chopped off.
You know that filament that was on the bottom of the Sun they paid somewhat attention to? Can anyone answer this question: How long would it take for the Sun to shoot that out into its atmosphere?
You are watching it 8 minutes and 20 seconds behind "real-time" as that is how long it takes for the light from the Sun to reach Earth
Pete Lawrence .
Needs A Dark Room Built .
How quickly do the prominences move? For example, during a flare, could you actually watch the sun being "alive" in real-time through that telescope?
Hey Brady, ever took a loot at the stars yourself? Do you own a telescope? Once again, good work. Cheers.
Vixen OTA, Vixen Mount.... Pete's a Vixen fan.
Hmm I didnt realize the sun rotated. Does the rotation of the sun affect the temperature or climate on earth?
Het Brady do you think you will adress this new diamond/carbon exo planet around Alpha Centauri B?
Looks like you have plenty of friends to let you use one when you're in the mood!
Can you explain how this image is converted into highly detailed image in color. I see amateur astronomers showing extreme high definition videos of the sun and I feel like they are just using some NASA stick footage from a multi million dollar telescope and misleading the viewers. Is it just digitally enhanced and artificially colored for wow purposes?
what is the start up cost for the equipment used? or what equipment would you recommend for a beginner looking into purchasing a similar setup
