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. ...
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...
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 ...
This nebula is a busy stellar nursery, with many new stars being formed there. But it isn't stars which researchers were interested in when they looked to the nebula -- in this case, they were studying objects called brown dwarfs. Bigger than most planets but smaller than a star, brown ...
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...
By placing the stars in a globular cluster on a Hertzprung-Russell diagram, astronomers can determine the cluster’s age by looking at the main sequence turnoff point and comparing it with models of stellar evolution. Astronomy: Roen Kelly Q: The globular cluster NGC 6397 is 7,800 light-...
A Day in the Astrobiology "Lab" Training to Join the Search Are We Alone? In the broadest possible terms, astrobiology is simply about life. How it comes to be. How it changes and adapts. What it needs to survive. If we can know all there is to know about life, we might be able...
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...
