The universe is rapidly expanding. Of that much scientists are certain. But how fast? And with what implications regarding the fate of the universe?
Ellen Jackson and Nic Bishop follow Dr. Alex Fillippenko and his High-Z Supernova Search Team to Mauna Kea volcano in Hawaii, where they will study space phenomena and look for supernovae, dying stars that explode with the power of billions of hydrogen bombs. Dr. Fillippenko looks for black holes--areas in space with such a strong gravitational pull that no matter or energy can escape from them--with his robotic telescope. And they study the effects of dark energy, the mysterious force that scientists believe is pushing the universe apart, causing its constant and accelerating expansion.
About the Author
Ellen Jackson is the award-winning author of more than fifty fiction and nonfiction books for children. Like her father, an amateur astronomer, Ellen has been interested in planets, stars, and galaxies since she was a child. She remembers family "star parties," at which neighbors were invited to gaze through her father's telescope at an eclipse of the moon or other astronomical objects.

Most Helpful Customer Reviews
This book follows Dr. Alex Fillippenko in his quest to find out just how fast the universe is expanding by using the light of far off super-novae to make his measurements. Jackson gives us a look into the field work of an astronomer as well as a few glimpses into his life outside the classroom and observatory. This book would be great to show kids that scientists are real people with real lives outside of their subject, not to mention that science class can actually be a fun place with the right teacher.
A supernova is a star that's ending its life in a fantastic explosion. They are so far away that light from a supernova can take billions of years to reach human eyes. Looking at a supernova is like looking back in time, seeing it how it was many, many years ago. Alex Filippenko studies supernovae. He also studies black holes.Why study supernovae and black holes? Scientists have determined that most of the universe is made up of things called dark matter and dark energy... and no one is sure exactly what those are. The more we study them, the closer we come to knowing what makes up our universe and possibly how it started and what will happen to it in the future.With brilliant photographs and informative sidebars, this is a great entry in the Scientists in the Field series. It describes the mysterious objects in our universe and makes it plain that there is lots that we don't know. A bibliography, list of resources for students and teachers, and an index round out the book.
