Name of first stars in universe?
We only name things that we can see, or detect. The first stars in the universe were likely supergiant stars that exploded in supernova explosions within a few hundred million years. The material blasted into space by the first three or four generations of rapidly-dying stars provided the raw material that came together to form our solar system.
What was formed at the same time as the sun?
Most of the planets probably formed within a million or so years of the time the Sun formed. That sounds like a long time, but for an astronomer that's a pretty short period. Looking further out, it's entirely possible that several nearby stars were formed about the same time as our solar system. Some theories of stellar formation suggest that a stable nebula of gas and dust is unlikely to coalesce without some external impetus, such as the shock wave from a "nearby" supernova. And we know that our solar system was formed from matter blown into space by probably several previous supernova explosions. (Otherwise, there would be no heavy elements such as lead, gold, or uranium - elements only created in supernova explosions! - on the Earth.)
How long does it take to make uranium?
The isotope U-238 has a halflife of 4.5 billion years, roughly the current age of the earth. As the sun is expected to consume the earth in about 6 billion years from now, less than 1.5 halflives will have passed by then. Therefore uranium will remain in the environment as long as earth exists, although at slowly decreasing levels.
Does the universe have more than one black hole?
The universe definitely has more than one black hole. Just in our galaxy alone there's an estimated 100 million of them, and the observable universe has at least 100 billion galaxies.
Can the earth go supernova?
No. There are two ways of generating a supernova: a star at least 8 times the mass of the sun collapsing and exploding or a white dwarf interacting or colliding with a companion star. Our sun is not massive enough to explode when it dies and does not have a companion star.

What would happen if a super nova hit earth?
A supernova is an exploding star. The Earth would be instantly incinerated, of course. There is approximately zero chance this will ever happen, though. If there was a supernova near Earth ... it would depend on how near. Betelgeuse is a good candidate for a supernova "soon" (within the next million years or so). Scientists who have modeled supernova explosions don't expect it will have much of an impact. If a star nearer than Betelgeuse were to go supernova, then it might be more serious.
What are the two largest known stars in the universe?
1. VY Canis Majoris 2. Betelgeuse (which is scheduled to supernova sometime between 2012 and a million years from now)
When will 24 hours of light exist on Earth because of a star going supernova?
When the second largest known star, in the universe, goes supernova, this will occur. (Estimates range from this happening in the year 2012, all the way to one million years from now.) The name of this giant star is Betelgeuse.
Is a cluster a group of galaxies?
the Virgo Cluster is a cluster of galaxies at a distance of approximately 59 million light years
Is the Coma cluster the nearest cluster?
The Coma cluster is one of the nearest clusters but it is not the nearest. At a mean distance of about 321 million light years the Virgo Cluster is closer at a mean distance of only 59 million light years.

What was copper used for in the past?
The copper on earth was created in a supernova explosion that predated the formation of our solar system (ie before 4600 million years ago). Copper elsewhere in the universe will have been created at different times in other supernova explosions.
What temperature does nuclear fusion happen for a star?
