On a mountaintop in Chile, excavators have just started work on a construction site. It will soon be home to a powerful new telescope that will have a good shot at finding the mysterious Planet X, if it exists.

"Planet X is kind of a catchall name given to any speculation about an unseen companion orbiting the sun," says Kevin Luhman, an astronomer at Penn State University.

A partial solar eclipse on Thursday has people looking forward to a total solar eclipse in the coming years.

MU Department of Physics and Astronomy hosted a viewing party Thursday afternoon at Laws Observatory so the community could catch a glimpse of the partial solar eclipse.

Ten-year-old Samuel Kingsley was at the event with his family and said he’s seen a blood moon before, but never a solar eclipse.

“It looked like someone bit the corner off the sun,” he said.

Samuel was just one of over 50 people who came out to watch the eclipse.


Astronomy enthusiasts and members of the public are invited to MU’s campus observatory Tuesday to watch the rare planetary passage of Venus.

For centuries people have lived and worked in a part of coastal Peru spotted with oddly shaped hills.  Most knew that the mounds were man made, but were they significant?

If you go stargazing tonight, you just might see a faint little speck with a Missouri connection.
