Midland Lutheran, in association with the NASA, is commemorating the 400th anniversary of the telescope and the International Year of Astronomy with a public unveiling of new images of the spiral galaxy Messier 101 at an event Thursday, Feb. 26 at 3:30 p.m. at the Eppley Auditorium on the Midland campus.
In 1609, Galileo improved the newly invented telescope, turned it toward the heavens, and revolutionized our view of the universe. In celebration of the 400th anniversary of this milestone, 2009 has been designated as the International Year of Astronomy.
Today, NASA’s Great Observatories are continuing Galileo’s legacy with stunning images and breakthrough science from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory.
Dr. Greg Clements will discuss the science and significance of the images, which will be unveiled by college president Dr. Stephen E. Fritz.
Twenty people will receive lithographs of the Hubble image of Messier 101, and refreshments will be provided. The public is welcome.
There will also be a presentation on the telescope, from its inception to the modern equipment in use today.
Midland is one of 116 partner institutions across the nation that have been selected to display these images. The images will be on display through 2009 at the Lueninghoener Planetarium.
While Galileo observed the sky using visible light seen by the human eye, technology now allows us to observe in many wavelengths, including Spitzer’s infrared view and Chandra’s view in X-rays. Each wavelength region shows different aspects of celestial objects and often reveals new objects that could not otherwise be studied.

This image of the spiral galaxy Messier 101 is a composite of views from Spitzer, Hubble, and Chandra.

• The red color shows Spitzer’s view in infrared light. It highlights the heat emitted by dust lanes in the galaxy where stars can form.

• The yellow color is Hubble’s view in visible light. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes.

• The blue color shows Chandra’s view in X-ray light. Sources of X-rays include million-degree gas, exploded stars, and material colliding around black holes.
Such composite images allow astronomers to see how features seen in one wavelength match up with those seen in another wavelength. It’s like seeing with a camera, night vision goggles, and X-ray vision all at once.
