That’s right; the title to this post is the same as the last.  The content and object is the same as well except in this post I wanted to give you a comparison to yesterday’s image of this object in radio light (wavelengths) and again today in infrared from the Spitzer space telescope in an effort to show you just how different objects can look when…..well, seeing them in a different light.

Also if you would like to help the Spitzer team identify objects go to http://www.milkywayproject.org/ and help sift through countless Spitzer objects and help catalog them. This is a Zooniverse project! https://www.zooniverse.org/

Some 4,200 light years away near in the direction of our galactic core, in the constellation Scorpius (The Scorpion) a giant has come to life.  This region known as RCW-120 (as well as a few other cataloged names listed below) is an H-II star forming region and emission nebula 10 light years across (59 trillion miles).  The star cataloged as CD -38 11636 or CGO 439 is an “O8 V” type star and in fact it’s the largest “O” type star known.  Over time this star will become very bright and possibly a prominent member of the southern night sky.

NAME: RCW120 , Sh 2-3, Sharpless 2-3, GUM 58.

WHAT IS IT?: H II star forming region & emission nebula.

HOW FAR AWAY IS IT?: Approximately 4,200 light years distant.

HOW BIG IS IT?: Approximately 10 light years across.

WHERE IS IT? (General): Constellation Scorpius.

WHERE IS IT? (Exact RA/DEC J2000):  RA 17h 12m 23.2s / −38° 26′ 51.2”.
