i just read that the moviments of pluto's smallest moons are more strange and unusual of what scientist belived, i will search more infos on this 

 

Edit : i found this :

here you may read a lot of things discovered on Pluto and moons

That's pretty interesting to see. I think what surprised me the most were how the satellites orbit around Pluto and how they are different compared to what we were expecting. The outer atmosphere was also pretty interesting to read about.

yeah, let's keep waiting new discoveries, what a complex orbital resonance!

May I recommend a show called Cosmos: A Space-time Odyssey if it hasn't already been mentioned? I believe this is a great show with a lot of great information and visual effects.

Oh I've seen quite a lot of this. It's a really cool show with loads of informative stuff, and I like it a lot. I don't think I've seen all the episodes though, so I might finish watching them.

I've seen every episode. Some could argue the show gets all Bono and unscientific towards the end because it starts discussing Venus' runaway greenhouse effect and starts talking about how CO2s and carbon is causing a similar problem here on earth. But I see it as scientific, and as such become greener.

But infortunately the subject of climate change is often denied or dismissed often makes it a hot button topic, and it's best we just ignore that part of the show before this wonderful topic gets locked. I wouldn't want to see this turn into a discussion of wether climate change is real or not.

you're right , I regularly visit some sites that talk about climate change and.... seem impossible to discuss civilly on this topic.
For me it's a shame because I'm passionate about meteorology.

Not sure if this topic belongs here, but hey I'll take that risk and post it on here lol. I also think a topic like this existed a very long time ago, but I assume that died out, so I might as well go ahead and make a new one.

 

Anyways, most people should know that I'm really into astronomy and anything related to the universe and because of that, I really want to become an astronomer when I get older. Personally, one of my favourite things when it comes to astronomy is the many kinds of star types ranging from white dwarfs to blue hypergiant stars. Another thing I love is observing the different kinds of nebulae that exist around us, e.g. Eta Carinae, Crab Nebula (which is also a supernova remnant I believe), Eskimo Nebula etc. and observing galaxies, which look really freaking cool, like the Sombrero Galaxy, the 2 Magellanic Clouds, the Cartwheel Galaxy, 'The Mice' etc

 

tl;dr I love astronomy

 

So, are you guys interested in astronomy as well? Feel free to share anything astronomy related.

I love astrology! I first found this video then I downloaded the StarView app on my phone. I know where nearly everything is in the sky!

[Eddy]

"Nearly everything" as in a very tiny fraction of the entire universe

 

Either way, that was one of the very first videos I've ever seen related to astronomy. Still amazing to see that our Sun is like a pixel in comparison to VY Canis Majoris. Though, in fact, VY Canis Majoris is now 8th on the list of largest stars in terms of radius I believe. The largest star recorded is now UY Scuti, located in the Scutum constellation, and it's insanely big. Roughly 1,708 times the radius of the sun.

What's even creepier if we want to change scale is that there are more cells in our body than there are stars in the entire universe. 

 

It doesn't matter how far we scale up large or scale down small, it certainly makes the realm of physics quite a fascinating and jaw dropping reality.

On the opposite side of Pluto there another little world, not yet officially categorized as dwarf planet,smaller than Pluto but  similar in many things :Orcus.

Just like Pluto it have  2:3 resonance with Neptune, making two revolutions around the Sun to every three of Neptune,It have  massive moon,called Vanth and is probable that is a binary system.

Orcus is always at the opposite way of Pluto, when one is at aphelion the other is at perihelion.

Dude... that's insane. I knew supernovas can outshine many things, but I never knew they can get that bright. I wonder what other crazy kinds of supernovae can be found with an insane amount of brightness like that.

yeah...i never belived it may be so MUCH powerfull

 

someone call this kind of supernova hypernova

2 interesting facts that I read in the paper :

 

-in a year there was a increase of 10% of the cosmic rays  that reach our planet, these rays come from stars outside our system and are generally blocked by  heliosphere , by the solar wind and by the Earth's magnetic field.

the topic interests me and I will try some other information

 

- Scientists speculate the presence of an ancient ocean , now frozen , on Charon , the freezing ocean, passing from liquid to solid state within Charon,  would increase its volume and cracked the crust
