Space Is Really, Really, Really Big

Sometimes we forget just how unfathomably huge space is and all the insane things that happen in it.


This is V838. It is a star that until 2002, wasn't that remarkable. Just another one in billions. That is, until it flared up to be 600,000 times brighter than our sun. Think about that for a second.



Those holes in the outer layers that get bigger? They're being physically ripped up by the radiation the star is giving off. That's how powerful it is.

This is the Herbig–Haro object HH47. A Herbig-Haro object is a patch of nebulosity associated with newborn stars. They are formed when gas ejected by young stars collides with clouds of gas and dust nearby at speeds of several hundred kilometres per second.



If you don't know how big what you're seeing is, this might help:


See that little line at the bottom? That line is 20 times the size of our solar system. Now look back at the other image.


I love space.

  4. We're just a pale blue dot, dancing on a sunbeam.

    That first image, I remember reading something about how it appeared the nova cloud was expanding faster than the speed of light but it was due to a special optical illusion. I didn't really understand it but the concepts of astronomy and cosmology are amazing.

  8. Great blog! Space is so interesting and there is always so much to explore.

    I really like the Digital Universe Atlas. I have the opportunity to play with a somewhat basic version of it sometimes and it is super cool

    The Universe Sandbox is also really fun! You may have heard of it, it's an interactive space simulator.
