Astro 1 Section 1 Professor Brandt Monday March 22nd 1999 Announcements: Lecture notes: Class 29. "More than meets the eye" In the last class we covered optical telescopes. Today we'll move on to talk about telescopes at other wavelengths. Photons at all different wavelengths are constantly impinging on Earth - we would miss huge amounts of information if we only used visual light to study universe. Slides shown - of different views from optical radio infrared and near infrared. COBE satellite - here can see cool low mass stars - like K and M stars which are cool enough to radiate down there. Gamma ray slide - most of gamma rays from our Galaxy were made when energetic charged particles slamed into gas clouds. At high Galactic latitudes see several active galactic nuclei (AGN) Radio Telescopes Going back to our plot of the electromagnetic spectrum we see that the other main range of wavelengths where astronomy from ground will work is radio.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
