Radio Telescopes: Like Car Radios, but Bigger

Posted on February 13, 2015 by alyssasolarblog

When we think “telescope”, we picture peering through a viewfinder or viewing images of the stars. However, visible light is only a small part of the electromagnetic spectrum; we can learn much about our galaxy by viewing visible light’s less frequent older brother, the radio wave. Radio telescopes are the technological descendants of actual radios (like … Continue reading Radio Telescopes: Like Car Radios, but Bigger → Continue reading →

Absorption Spectra

Posted on February 12, 2015 by jamej00

Photo Source: Absorption Spectrum The photo above is the full absorption spectrum of the sun.  The black lines come from the different chemical elements within its atmosphere, and this is true for all stars!  Different elements absorb and emit light at different wavelengths from one another.  Scientists have conducted (here on earth) experiments to determine… Continue reading →

Tidal Changes from a Beach Stand

Posted on February 12, 2015 by dillonkoval

I worked for two years renting out beach umbrellas and chairs at Assateague State Park for two summers in high school. I would walk out to the beach and set up my little stand next to a fence used to protect the dunes from wandering beach-goers. Assateague has a very large sandbar and some days […] Continue reading →

In April 1990 NASA launched the Hubble Telescope in an orbit around Earth. The telescope has been orbiting Earth for almost 25 years and is monumental in its contribution to science. The information gathered by the telescope has helped astronomers to narrow down the age of the universe down to a few hundred million years, […] Continue reading →
