Your Tax Dollars At Work

NASA’s Picture of the Day for January 1, 2013:


Here’s the image caption:

The Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame.

This face-on galaxy, lying 45 million light-years away from Earth in the southern constellation of Fornax (The Furnace), is particularly attractive for astronomers. NGC 1097 is a Seyfert galaxy. Lurking at the very center of the galaxy, a supermassive black hole 100 million times the mass of our sun is gradually sucking in the matter around it. The area immediately around the black hole shines powerfully with radiation coming from the material falling in.

The distinctive ring around the black hole is bursting with new star formation due to an inflow of material toward the central bar of the galaxy. These star-forming regions are glowing brightly thanks to emission from clouds of ionized hydrogen. The ring is around 5000 light-years across, although the spiral arms of the galaxy extend tens of thousands of light-years beyond it.

Just think:  if the Teahadists have their way, none of the engineering or aspiration that made the Hubble possible would see the light of day (or night) in the future.  Just sayin’.

    I’m starting up a new online website directory and was wondering if I can submit your website? I’m hoping to increase my directory slowly by hand so that it retains
    quality. I will make sure and put your blog in the correct category and I’ll also use, “Your Tax Dollars At Work | The Inverse Square Blog” as your anchor text. Make sure you let me know if this is ok with you by e-mailing me. Thank you
