Outflows & Shining Dust

L1448 
Nebula

Outflows glowing red with excited hydrogen and a small blue reflection nebula frame L1448 in the southwest of Perseus. Ambient starlight reflects off dust density features in this small star-forming cloud, providing an unprecedented high-resolution view of its complicated structure. (frame is 15' x 15')

Internal Structure of Dust Blobs Revealed

This overlay of our 1-mm (MAMBO/IRAM) dust map (contours) on our deep (Calar Alto) JHK color composite image shows how the near infrared literally highlights the edges of dense structures within molecular clouds. (frame is 15' x 15')
