A Star Is Born: How Stellar Newborn Illuminates a Hidden NebulaA luminous newborn star has been captured by the EuropeanSouthern Observatory. On Wednesday, the...Fedde, Corey
If the cosmos is infinite, it is infinite. On the Big Bang, it was constantly dense. Space has gotten less dense since that time. The hyper-sphere would not have adequate curvature in the infinite situation.Answer and Explanation: Naturally, the observable Universe is considerably larger. ...
A third category – nebulae with spiral structure – particularly intrigued astronomers. TheAndromeda nebula, M31, was a prominent example. It’s visible to the naked eye from a dark site. Astronomers as far back as the mid-18th century had speculated that some nebulae might be remote systems ...

Hubble's Law is a major piece of evidence that the universe is expanding — his work formed the basis of the big bang theory of the origin of the universe. The Doppler Effect Much like the high-pitched sound from a fire-truck siren gets lower as the truck moves away, the movement of...
An astronomical unit represents a practical average, rather than a precise measurement, of our distance from the sun. You may like How fast is Earth moving? What is a solar eclipse? NASA's daredevil solar spacecraft survives 2nd close flyby of our sun Related: How big is Earth?
but thanks to space telescopes likeHubble, we know one thing for certain -- our universe is gorgeous and it shoulddefinitelybe part of your decor. So bring a bit of the infinite majesty of the cosmos into your home by turning some plain old cushion covers into a stellar piece ofnebula ...
What is the distinction between a nebula and a galaxy? Why is bigger better for astronomical telescopes? Name the most recent modification of the standard Big Bang model, and briefly explain how it differs from the standard model. Why do you think it took so long for astronomers to accu...
But finding the size of a star is hard to do. Yes, it's because they're far away, and we can't reach them directly. Yes, we don't have a ruler big enough to measure them. Yes, we'd be burned alive if we even tried to get too close even if we had a big enough ruler. ...
I have to play the limited sky and what is in that sky to pick targets, there are a good # of clusters that I see on the list that are in my viewing angle, orion is about as far to the low western sky and the big dipper is about my northern limit Jupiter is probably just ma...
