Orion Widefield

Here's another from my excursion last night

Notice the star in the top left, how it's orange compared to the rest? That's Betelgeuse (pronounced beatlejuice), and it's more than 1,000 times bigger than our sun. It's older, and could blow up into a supernova at any minute. It might already have, but we wouldn't know because it's several lightyears away.

It's older, which means it's colder, hence the orange. The hottest stars burn blue.
