How Far Away Are They?

Aug
27

Marusa Bradac: I do astronomy because it fascinates me. And it is the simplest things about it that amaze me most. I still remember times when I was a little girl watching stars with my dad in my home country Slovenia and wondering, "how far away are they?" I also remember how exciting it was when I first saw the Andromeda galaxy in our backyard. These days I moved on to much bigger things called clusters of galaxies. But the excitement of the question of how far away they really are is still there.

Nine years ago this week, Chandra was launched aboard the Space Shuttle Columbia (sadly lost in the tragedy of 2003). While the satellite has performed excellently since it was deployed on July 23, 1999, there was a little drama in getting it going.

And, fireworks are often slightly different from one another – even if they originate from the same type of explosion. Of course, if they have different types or proportions of chemicals before in the explosive itself, the fireworks can look dramatically different. And, don’t forget that the environment they explode into – include wind or clouds of smoke – can affect how they look.

Try Out the Universe on Your Desktop

In the last year we have seen tremendous development in visualizing the Universe through the digital world. Google Sky and Wikisky are examples of this progress. These interfaces have taken well-known all-sky surveys and detailed observations to create virtual observatories that show our nearest planetary neighbors, like Mars and Jupiter, to the most distant galaxies in the Universe.
