PREVIEW: Satellites (Deep Sky Videos preview)

[midkiffjd]

it's the tracks that change direction that I want to see.

[esperoni05]

Great teaser!! Looking forward to January. Feel free to post some more. Don't feel you have to wait until then to upload some content. HaHa!!!

[legochuckles]

I can't wait for these videos!

[culwin]

I can't wait for January!!!

Where does Brady keep his raw footage?

[scottjacko87]

Whoo I so cannot wait for January. This is going to be awesome :D I have even told a few of my friends about this channel.

[DeepSkyVideos]

@scottjacko87 thank you for spreading the word!

[tmafkap]

Looking forward to see the whole thing. BTW, Brady, instead of writing down my wish list with thousand topics, could you make a video for sixtysymbols and deepskyvideos for viewer's questions like you did for periodicvideos?

[DeepSkyVideos]

@tmafkap we've done it a few times already... click the question mark on the sixty symbols website!

[SpartanStig117]

i often wonder if there are people in the galaxies we look at looking at our galaxy and wondering if there are people in it looking back at them

[PullarBearBear]

@SpartanStig117 If there are, then they would be looking at us living in caves with fires lit on wood; because light takes time to travel there, and the only light they're seeing are probably during the Early Ages.

[SpartanStig117]

@PullarBearBear true but they wouldn't know what stage of development we are at

[Static172]

January? C'moooooon!

[gulllars]

Looking forward to full lenght content from this channel :)

Astronomy and astrophysics is interresting, and has some really great images.

[muzammilali007]

Looking forward to the final video :)

[Zee96969696]

so what is the solution to the problem and why is it a problem to start with and just what is that person in the video taking picture in the sky for?? and what happens if satelites crash????

[BGenerous]

Subbed a while back after seeing a mention in the comments on a sixty symbols video. Always eager to see the next Brady Haran production!

[WillEyedOney]

More!

[boswell255]

Dear lord, the related videos make me weep for humanity.

[5T34LTHcamoT4NK]

an these spy setillite never happen to crash by any ways?...

i think its not that much crouded if you think about it, your looking over a few km of ozon up there you know, and these things a still close from earth going over a few thousand km/h

[Squagnut]

There was nothing in this vid which I didn't understand, but then I do astronomy. Perhaps a few primer vids would be in order, to give less clued-up viewers some grounding in the subject?

[WeaselWJ]

Thanks for the video.

[PullarBearBear]

What... it's still a preview? *disappointed*

[DeepSkyVideos]

@PullarBearBear it's a pretty content-filled preview I thought!!!!

[PullarBearBear]

@DeepSkyVideos Well, when you start from one random topic in the middle nobody really understands much. =/

[DeepSkyVideos]

@PullarBearBear really! you didn't understand much?

really?

[SpartanStig117]

@PullarBearBear you must be new to astronomy

[PullarBearBear]

@SpartanStig117 Only on the telescope side. :/

[DeepSkyVideos]

@PullarBearBear fair enough... I just wanted to share some of the cool stuff with all the people like you who have been kind enough to subscribe early, etc... I might post a couple more (?) but things will really heat up in January! :)

[PullarBearBear]

@DeepSkyVideos As a matter of fact, I did learn something. xD

I didn't know satellites would interfere with the images, which led me thinking: what kind of telescope do you use? I didn't think it would be a normal optical telescope that kids have, since the satellite itself would have to give off light to get detected. (If this were the case then we would be getting UFO reports almost every night, seeing a light in the night sky move across.)

Also, is there any chance of satellites colliding?

[BGenerous]

@PullarBearBear It is a normal optical telescope. In fact you can see satellites with the naked eye. Shortly after sunset or before sunrise, while the sky is dark, satellites are high enough to be out of Earth's shadow so they are in full sunlight. That's why Nik says at 1:16 that he frequently sees them in early evening. There are web sites that will help you find out when certain satellites will be visible at your location.

[argh523]

@PullarBearBear Satellites are mainly a problem around sunset/-rise since they only reflect sunlight, so in the middle of the night you won't see them. However, in summer, the closer to the poles you are, the longer it takes until they are in earths shadow (after sunset from your POV), ontop of the night beeing shorter. So, in southern australia, they may be a bigger problem than elsewhere.

[argh523]

@PullarBearBear Colliding: there's _lots_ of space, never happend. However, there's lot's of pieces of junk which are _very_ fast. Something like a tennisball hitting the ISS would just rip through whatever it hits.

So, craches are very unlikly, but when they happen, they're very dangerous.

[wowkarbonkel]

YAY! another video
