Intro Astro Videos

I haven’t posted in a long time. The end of school has occupied a lot of time. Look for more posts though as the summer progresses.

One of my Twitter friends told me about these cool introductory astronomy videos.

This one features lots of thrown balls to demonstrate the discrete energy levels in an atom.

Sky & Telescope – Imaging the Orion-Eridanus Superbubble

Posted in astro blogs, galactic astronomy, observing, space, stellar astronomy, urban skies with tags , , on March 10, 2009 by bellaireastro

There is an AWESOME web-extra over at SkyandTelescope.com all about the efforts of 2 of the staffers to image the Orion-Eridanus superbubble from suburban Boston.

The story and technique information is great but the images are absolutely astounding. They require that you zoom in and pan around the various parts to see all the amazing details of these very familiar areas in our night sky.

You can see the massive amount of interstellar gas spread over this vast area. It is unbelievable what amateur astronomers can accomplish in this day and age. Citizen scientists indeed. Very impressive work by Dennis di Cicco and Sean Walker.

Last Thursday my astronomy went to the George Observatory at Brazos Bend State Park (which is run by the Houston Museum of Natural Science) for an observing session. The weather was cold and clear and the transparency was great.

Our tour guide was the always-knowledgeable Barbara Wilson. We managed to make it through all of the objects on the list.

  • Venus (awesome crescent through the scopes)
  • M 31 (Andromeda Galaxy)
  • NGC 884 (Double Cluster in Perseus)
  • M 37 (Open Cluster in Auriga)
  • M 1 (Crab Nebula Supernova Remnant)
  • M 42 (Great Orion Nebula – Star Forming Region)
  • NGC 2264 (Christmas Tree Cluster)
  • NGC 2261 (Hubble’s Variable – Nebula)
  • NGC 2392 (Clown Face or Eskimo Nebula) – students called this one the Simba Nebula

The equipment in the research dome at the George is impressive and we got to use it just for the class! It was a great time and I recommend area teachers take their classes out to the George for a session.

Jill Tarter TED Prize

I just watched the video of Jill Tarter’s talk about winning the 2009 TED Prize for her work on SETI. It is a must watch.

We are the products of a billion year lineage of wandering stardust. We are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.”

Astronomy.com – Milky Way a swifter spinner and more massive, new measurements show

Astronomy.com – Milky Way a swifter spinner and more massive, new measurements show.

I saw this story in several places so I decided to post it after all. It turns out the milky way, our galactic home, is more massive and is spinning faster than once thought. The interesting thing is what this means for our future run in with the Andromeda Galaxy.
