Our Night Sky: August 2009

Monday, August 3rd, 2009

In this month’s episode of Our Night Sky, I focus on the AAVSO’s Citizen Sky Project and how you can contribute to their studies of the enigmatic variable star, epsilon Aurigae.  This episode also features two beautiful digital renderings from Ewan Bryce, aka @Space_Jockey. You can see more of Ewan’s work, here; and you can watch the full version of Astrocast.TV‘s August episode, including Carolyn Collins Petersen‘s The Astronomer’s Universe and Bente Lilja Bye‘s A Green Space A Green Earth, here.

Announcement – New Astronomy Fun!

Thursday, April 30th, 2009

I’ve a couple of exciting announcements I’d like to share with everyone!

First, Astrocast.TV‘s latest episode, #14-May, airs today with two new monthly segments and three new gorgeous ;) reporters.  Astrophysicist and Earth Science Expert, Bente Lilja Bye, reports on Earth observations from space with A Green Space – A Green Earth;  Carolyn Collins Petersen’s The Astronomer’s Universe leads us through the cosmos with a focus on the latest astronomy research;  and Tavi Greiner (that’s me) is the new host of Our Night Sky, an existing monthly segment featuring amateur observing opportunities and skywatching tips.  This month’s episode also includes a solar report from University of Maryland Research Associate, Dr. Lori Feaga, and news about the hypothetical impactor planet, Theia, from NASA JPL Solar System Ambassador, Greg Redfern.

Second, there’s a fun new place for amateur astronomers to hang out.  Astronomy.FM is a community-themed astronomy site offering space news, image sharing, blogs, a forum and chatroom, and even radio.  The best thing about it, members are encouraged to actively participate through a number of venues.  You can even learn more about robotic imaging by “sitting-in” on some of the members’ imaging sessions with the Canada-based observatory, My Telescope.com.  Registration is simple and free, so stop by and give it a look.

So, two things to include in your astronomy endeavors today – watch the latest episode of Astrocast.TV and check out the Astronomy.FM community!

Jupiter and Company

Sunday, April 26th, 2009

Finally! I saw Jupiter in the morning sky.  Of course, I’ve seen it there before, but not yet this season.  Venus and Mars were there too, slightly east, but the trees block them from my view.  All three planets will grace the morning sky throughout the month of May, so I’ll make a point to find a good SE horizon one morning soon.  And I’ll even talk about May’s morning planets on Astrocast.TV’s next episode of Our Night Sky, coming May 1.

This image was taken just as Europa and Io were “crossing paths,” with Europa moving toward Jupiter and Io moving away. (You can click the image for larger size and click the x in bottom-right corner to close.)
