Cometary Globule L1622 (Subaru-DSS Composite) by Robert Gendler
Bright rimmed globules and their more evolved cousin, the cometary globule, represent fascinating dynamic structures formed by the interplay of cold molecular clouds and hot ionizing stars.
Typically the head of the globule faces a hot O-type star. Intense radiation from the star boils away lower density gas from the head. The evaporated rim of gas becomes ionized by the stars ultraviolet flux forming a bright glowing rim we associate with many of these globules like LDN 1622 (Beverly Lynds’ Dark Nebulae Catalog) .
The Orion superbubble contains dozens of Cometary Globules illuminated by OB stars within the Orion OB1 association. L1622 is superimposed on the northern part of Barnard’s Loop at the northeastern periphery of the Orion B molecular cloud. LDN 1622 is actively forming young stars.The most conspicuous YSO (Young Stellar Object) in LDN 1622 is HBC 515, located at the head of the cometary cloud facing the Orion OB1 association.
A prominent reflection nebula opens toward the southwest. There are also several faint Herbig-Haro objects north and west of HBC 515.
-Oh the weather outside is weather
But the fire is so fire
Since we’ve got no place to place
Let it snow, let it snow, let it snow-
Boom, can finally reblog this as its CHRISTMAS
IT’S FUCKING JULY WHY IS THIS ON MY DASH
This is my reason for living
fun drinking game for the kids: listen to fall out boy. every time patrick sings ‘ohhhhh’ or ‘woah’ take a shot
you will die
believers never die
How to enjoy winter:
When you see your breath pretend you are
a) a fucking dragon
b) a steampunk robot letting out steam
c) Danny Phantom
d) a titan about to eat an unsuspecting family
i have never witnessed batman shoot steam out of his face but whatever floats your boat man
it’s never a bad time to pretend you’re batman
