M2-9: “Minkowski’s Butterfly” processing by Judy Schmidt
Minkowski 2-9, abbreviated M2-9 is a planetary nebula that was discovered by Rudolph Minkowski in 1947. It is located about 2,100 light-years away from Earth in the direction of the constellation Ophiuchus.
Messier 78 (NGC 2068)
An ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth; it is commonly called the Elephant’s Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. [image via]

Sweeping the Dust from a Cosmic Lobster
New infrared VISTA image of NGC 6357
A new image from ESO’s VISTA telescope captures a celestial landscape of glowing clouds of gas and tendrils of dust surrounding hot young stars.
This infrared view reveals the stellar nursery known as NGC 6357 in a surprising new light. It was taken as part of a VISTA survey that is currently scanning the Milky Way in a bid to map our galaxy’s structure and explain how it formed.
Located around 8000 light-years away in the constellation of Scorpius (The Scorpion), NGC 6357 — sometimes nicknamed the Lobster Nebula due to its appearance in visible-light images — is a region filled with vast clouds of gas and tendrils of dark dust. These clouds are forming stars, including massive hot stars which glow a brilliant blue-white in visible light.
Here astronaut Don Pettit demonstrates the effects of rotation on a sphere of water in microgravity. Bubbles, being less dense than water, congregate in the middle of the sphere along its axis of rotation. Tea leaves, which are denser than the water, are thrown to the outside; this is the same concept used in a centrifuge for separating samples.
