APOD: Infrared Trifid (2015 Jul 25)

Infrared Trifid
Explanation: The Trifid Nebula,
also known as Messier 20, is easy to find with a small telescope, a well known stop in the
nebula rich constellation
Sagittarius. But where
visible light pictures show the nebula divided into three parts by dark, obscuring dust lanes,
this penetrating infrared image reveals filaments of glowing dust clouds and newborn stars. The spectacular false-color view is courtesy of the
Spitzer Space Telescope. Astronomers have used the Spitzer
infrared image data to count newborn and
embryonic stars which otherwise can lie hidden in the natal dust and gas clouds of this intriguing
stellar nursery. As seen here, the Trifid is about 30 light-years across and lies only 5,500 light-years away.

In the forbidden temple, apparently. (Bystander saw this earlier and emailed the editors about it, so they know.)

Thanks, Chris!
I found this a little irritating:

But did they tell us how many they had counted?

The fact that the picture AOPD many years every day on my desktop, but it's empty ...

Meanwhile, there's a
960x1563 px image in portrait orientation at the Spitser site at CalTech, that looks to be the same image.

Spitzer Finds Stellar 'Incubators' with Massive Star Embryos
Spitzer discovered 30 embryonic stars in the Trifid Nebula's four cores and dark clouds. Multiple embryos were found inside two massive cores, while a sole embryo was seen in each of the other two. This is one of the first times that clusters of embryos have been observed in single cores at this early stage of stellar development.
Spitzer also uncovered about 120 small baby stars buried inside the outer clouds of the nebula. These newborns were probably formed around the same time as the main massive star and are its smaller siblings.

Day of the Trifids.....dunt, dunt, duuuuuuun......
Very interesting view into this nebula. Always something behind the scenes...and not always Sinister....
