The sky finally clears!

Last night was the first time I got to use my new telescope that I got from Telescopes.com. It was delivered on July 17th and, with one exception, the sky has been cloudy every… single… night! Finally, last night, there were enough clear spots that I could get a nice view of the moon and the detail. The view, even without a filter, was terrific. Megan was pretty excited about it, too (Lori took a look and said she saw footprints. Ha!).

The moon was probably only about one-third full, but there were lots of craters visible with great resolution. I used a 20mm eyepiece to position everything (about 50x magnification) and then switched to a 10mm eyepiece (100x) to get more detail. I almost expected to see the LRO cruising around the moon!

I’ll be taking a drive with the telescope to a much darker location with less light pollution soon, so I’m hoping to get an even better moon view and some great views of a planet or two… if I can find them. I’m still not fluent with the whole astronomical coordinate language yet, so that’s going to be tough for awhile.

I’m really looking forward to a clearer night with a fuller moon.

We are very tiny

I came across this video this weekend and wanted to share it. I’ve seen static images with size comparisons of the planets in our solar system, our sun, and other starts in our galaxy, but this video makes it significantly more dramatic.

It also uses the music from Disney’s movie The Black Hole, which, despite it’s scientific shenanigans with physics, is just a fun, fun movie.

(For the best effect, click the “HD” button and then make it full screen. Good stuff!)

…in a galaxy far, far away…

Artist's interpretation of Fomalhaut

Yesterday, I read that astronomers had actually photographed planets outside our solar system for the first time. Planets had been detected before, but always by methods other than direct visuals. This is the first time they’ve actually seen an object this cool (temperature-wise) and this small outside our own solar system, according to aBBC article (linked below).

To me, that’s just phenomenally cool. Astronomers viewing other galaxies and deep space features like gas clouds and nebulae has produced images that are just fundamentally awe-inspiring, showing a universe that is at once beautiful, mysterious, and scientifically enthralling. Seeing actual planets gives spine-tingling shivers to those of us who have imaginations that love to wander around the speculative playground of extraterrestrial life.

I never got to see Star Trek much as a kid, but Science Fiction has always fascinated me from an early age. Seeing images of space from astronomers’ telescopes always ignites a feeling of wonder and appreciation for the vastness of the universe and gets my imagination soaring around space travel, exploration, alien life, terra-forming, and all kinds of other fantastical ideas. It also piques my scientific curiosity about how the universe works, how it formed, and where it’s headed.

Kudos to the astronomers who made this new planetary discovery. Keep up the great work and know that you’re not only making leaps of scientific progress, but you’re providing inspiration and joy to those of us who step into the images of your discoveries… if only in our minds.

Here’s a link to an article about the discovery: http://news.bbc.co.uk/2/hi/science/nature/7725584.stm
