This NASA spacecraft was launched on Jan. 19, 2006, and has been traveling to Pluto for the last 9½ years. It’s traveling too fast to go into orbit around Pluto, but on the morning of July 14 it will pass by 7,000 miles from the surface at nearly 8.6 miles per second.

The Earth and Mars will be on opposite sides of the sun for most of the month of June, an alignment called Mars solar conjunction.
You can explore the solar system on a nice day in Walla Walla by taking the Planet Walk.
Saturn, the sixth planet from the sun, is the gem of the solar system because of its icy white ring system.

In the past few weeks I’ve been asked several questions about the northern lights, also called the aurora borealis. In this month’s column I will answer some of these questions and introduce you to this mysterious and unpredictable display of light in the night sky.
When you see images and hear reports from NASA missions, do you ever wish that you could be part of the team? If so, your wish may be coming true.
If you missed the supermoon on July 12, you’ll get second and third chances to see one on Aug. 10 and Sept. 9.
All objects in the sky appear to rise in the east and set in the west. The stars are not really moving; it is the rotation of the Earth from west to east that causes this apparent clockwise motion. The speed of this rotation is so constant that it can be used to keep time.
