1. Quintet
Quintet: One light year = 6 trillion miles.
- Pinkish Stars are infant Stars (10 million years old), Blue Stars are young Stars, Red Stars are old Stars.
- NGC 7319 (top right), a barred spiral Galaxy
- NGC 7318A, NGC718B Galaxies (center). It may look like one Galaxy with two core centers, but it’s actually two separate Galaxies.
- NGC 7317 (bottom Left), an elliptical Galaxy
- The above 4 Galaxies are 290 million light years from Earth in the constellation Pegasus.
- NGC 7320 Galaxy (upper left), 40 million light years from Earth. - Image credit: NASA, released date Sept. 2009

2. Air Pump Galaxy
Air Pump Galaxy: Spiral galaxy is a 110 million light years (110 million X 6 trillion miles) from earth.
- Part of the Antlia cluster, a group of 200 galaxies held together by gravity.
- Characterized by an extremely bright nucleus and very strong emission lines from certain elements — hydrogen, helium, nitrogen, and oxygen.
- The bright center of the galaxy is thought to be caused by the ejection of huge amounts of super-hot gas from the region around a central black hole.
- The name "Air Pump" is in honor of French astronomer Louis de Lacaille who invented the air pump.

3. The Butterfly Nebula
The Butterfly Nebula is 4,000 light years (4,000 X 6 trillion miles) from Earth
- A nebula of a dying star (nebula = region containing above average density of Interstellar Gas and Dust).
-The Butterfly wingspan covers 3 light years (18 trillion miles).
- Surface temperature of this star in the constellation of Scorpius is about 250,000 degrees Celsius.

4. Like a Whiff of Smoke
Like a Whiff of Smoke:
- Resembling the puffs of smoke and sparks from a summer fireworks display, these delicate filaments are actually a supernova remnant within the Large Magellanic Cloud, a nearby small companion galaxy to the Milky Way.
- DEM L 190, this remnant is from a massive star that died in a supernova blast whose light would have reached Earth thousands of years ago.
- This filamentary material will eventually be recycled into building new generations of stars.
- Our own Sun and planets are constructed from similar debris of supernovae that exploded in the Milky Way galaxy billions of years ago. image NASA

5. Core of the Milky Way
Core of the Milky Way: This sweeping panorama, 300 light-years in width (1,800 trillion miles), is the sharpest infrared picture ever made of the core of our Milky Way galaxy. It offers a nearby laboratory for how massive stars form and influence their environment in the often-violent nuclear regions of other galaxies. The galactic core is obscured in visible light by intervening dust clouds, but infrared light penetrates the dust. This view combines the sharp imaging of Hubble’s Near Infrared Camera and Multi-Object Spectrometer (NICMOS) with color imagery from a previous Spitzer Space Telescope survey done with its Infrared Astronomy Camera (IRAC). The NICMOS mosaic required 144 Hubble orbits to make 2,304 exposures. NASA
6. Orion Nebula
Orion Nebula: This magnificent image from NASA’s Spitzer and Hubble Space Telescopes shows the Orion Nebula in an explosion of infrared, ultraviolet, and visible-light colors. It was 'painted' by hundreds of baby stars on a canvas of gas and dust, with intense ultraviolet light and strong stellar winds as brushes. At the heart of the nebula, in the brightest part of the image, is a group of four monstrously massive stars, collectively called the Trapezium. Located 1,500 light-years (9,000 trillion miles) from Earth, the Orion Nebula is the brightest point in the sword of the Hunter constellation. NASA
7. Star V838 Monocerotis
Star V838 Monocerotis: The red supergiant star in the center of this image brightened suddenly for several weeks in 2002, illuminating dust that may have been ejected from the star during a previous explosion. The illumination of interstellar dust comes from the red supergiant star at the middle of the image, which gave off a pulse of light three years ago, somewhat similar to setting off a flashbulb in a darkened room. As light from the stellar flash echoes across pre-existing dust shells around Star V838 its appearance changes dramatically. Star V838 Monocerotis is located about 20,000 light-years, 120,000 trillion miles away from Earth in the direction of the constellation Monoceros, placing the star at the outer edge of our Milky Way galaxy.
