Monday, Dec. 8, 2014: Stars form in textbook fashion inside emission nebula NGC 2174, where molecular clouds condense into star formation regions. New stars next slowly blow unused material back into the interstellar medium. After the lengthy process has almost concluded, the stars have broken out into the open.

Experiment examining a SLICE of the interstellar medium:    (Phys.org)—When you look up at the stars at night, the space between stars looks empty. But, yes there is something there. It's called the interstellar medium. An experiment from the University of Colorado will fly on a NASA suborbital sounding rocket from the White Sands Missile Range in New Mexico on December 15 to study this space between the stars.

The Triangulum Emission Nebula - NGC 604Located 2.7 million light-years away in the constellation Triangulum lies the massive nebula known as NGC 604. Though such nebulae are common in galaxies, this one is particularly large, nearly 1,500 light-years across, and it dominates a portion of galaxy M33’s spiral arm. Nebula NGC 604 is also an area of intense star formation. At the heart of the nebula there are over 200 hot stars, most are more massive than our Sun with the largest being up...
