BIG.....mind blowingly BIG....betelgeuse supernova

Re: BIG....................mind blowingly BIG....

There's something else in the sky at night atm next to the moon which is getting bigger by the day and is said to be mars. Not sure how true this is as a randomer told me it was mars but there's definetly something there and it is Considerably bigger than a star.

the space station is very bright,and it is the most brightest out there,its twice the size of the north star.
so ive been told, could be wrong.

Re: BIG....................mind blowingly BIG....

mars and saturn aren't really visible atm, and venus is in the morning sky. jupiter is very visible in the night sky, esp. after midnight, my guess is it's that. deep yellow colour, many times brighter than a star. I never get tired of gazing out of my window at it. I don't know how it lies in relation to the moon tho, when I've looked at it, it's been well accross the sky to the south/west, but they change position relative to each other throughout the night, don't they? my head hurts every time I try and figure that stuff out.

The brightest star in the sky is Sirius and the ISS is no where near as bright as that, so is definitely not the brightest object . Jupiter on the other hand is currently extremely bright in the night sky.
There is an email doing the rounds saying that Mars is getting bigger in the sky and will eventually be bigger than a full moon, absolute bollocks. Mars will only appear as a small red point to the naked eye.

Thought it was bullshit, dosent the iss travel about 17,000 mph or summet...

Yeah it's orbit takes about 90 mins, so it's moving pretty quick. When it's actually finished and it is in full sunlight (and you are under dark skies) it will rival the brighter stars in brightness but usually it is only about 2nd magnitude ( Sirius is about magnitude -1.5, the sun about -26)

Re: BIG....................mind blowingly BIG....

Ive only just found this thread Allan, "what a great topic and the pictures are fierce". Whenever you hear the old chestnut that "we are the only civilisation in the universe," the more you think its a load of bolox. My mate set up his tri-pod to view this flickering star looking object, he left it for 20mins, and when he went back to it, the object had moved to near enough out of frame. "I'm getting more and more interested in what exactly is out there", although i have some way to go to get to the knowledge of the OP and some of the other contributors to this thread. Just slightly off the theme, and dont mean to ambush your thread Allan,but, !where do we stand on the belief/non-belief of life on other planets, or solar systems, particularly the Reptillian agenda".(and please, "leave the silly responses for another time".)

This link gives you the flight path of the iss

when do they think it will be finished for?

Nearby star Betelgeuse has been noticably shrinking over the past decade indicating that it may by now have gone supernova, at 600 light years away.

So far though its only shrinking and not losing any brightness or gaining any.

Thing is........we have no idea how the whole supernova process works up close. We only see the extreme aftermath in any detail.

If it does blow it will depend on the axis if we are in danger or not. It isn't the explosion that is the killer.......its the x and gamma rays shooting from the poles like highly energized death rays. If one of those is pointed in our direction we are in serious trouble.

This is one to keep your eye. 15% of a stars mass over 15 years is not something that you would think could happen. We are taught these events take billions, millions and thousands of years to happen. So its possible we are seeing the lasts moments before a supernova as everything begins to speed up.

Re: BIG....................mind blowingly BIG....

Compared to that, we must be smaller than atoms!

It's all relative...

Fantastic gif that btw, seen it before and used it for teaching purposes, makes you begin to realise the true scale of the cosmos and our place in it...
