Astro-image of the day: Andromeda Galaxy in infrared

This stunning photograph of our neighbor galaxy was taken in the infrared. Astronomers were excited to discover that the stellar population estimate remains the same in this wavelength as in visible light... get this: one trillion stars. That's compared to four hundred billion stars in our galaxy.

Click the image to see the story.

Four hundred billion stars. Can you imagine that? How about a trillion?

The universe is astounding.

PS: If you don't read back to yesterday's late-night postings, you might have missed yesterday's Astro-image of the day, posted just before midnight, about dark matter. Cool stuff.

Best,
Chris
