In Orion, There Really is a Hole in the Sky



A new image from ESO’s APEX instrument shows a cloud of gas and dust in the Orion region. Image credit: ESO

When astronomers see dark regions in nebula in visible light, they know there’s something going on. There’s got to be some kind of star forming activity pumping out material that obscures the view to the newly forming starts. Switch to infrared and you can peer through that intervening dust to see the young stars at work.

I'm looking through a hole in the sky
I'm seeing nowhere through the eyes of a lie
I'm getting closer to the end of the line
I'm living easy where the sun doesn't shine
