Total Lunar Eclipse tonight!

Tuesday morning, Aug. 28 brings us the second total lunar eclipse of 2007. Those living in the Western Hemisphere and eastern Asia will be able to partake in at least some of this sky show.

The very best viewing region for viewing this eclipse will fall across the Pacific Rim, including the West Coast of the United States and Canada, as well as Alaska, Hawaii, New Zealand and eastern Australia. All these places will be able to see the complete eclipse from start to finish.

Europeans will miss out on the entire show, as the Moon will be below the horizon during their mid and late morning hours.

For more details, check Space.com or NASA's page.

Huge Hole Found in the Universe

The universe has a huge hole in it that dwarfs anything else of its kind. The discovery caught astronomers by surprise.

The hole is nearly a billion light-years across. It is not a black hole, which is a small sphere of densely packed matter. Rather, this one is mostly devoid of stars, gas and other normal matter, and it's also strangely empty of the mysterious "dark matter" that permeates the cosmos. Other space voids have been found before, but nothing on this scale.

Astronomers don't know why the hole is there.

"Not only has no one ever found a void this big, but we never even expected to find one this size," said researcher Lawrence Rudnick of the University of Minnesota.

Rudnick's colleague Liliya R. Williams also had not anticipated this finding.

"What we've found is not normal, based on either observational studies or on computer simulations of the large-scale evolution of the universe," said Williams, also of the University of Minnesota.
