M27 the dumbbell nebula



this is the future of our sun in a few billion years. about 10000 years ago a sun type star at the end of its life shed its outer layers and became a white dwarf. the nebula is expanding at about 31 Km/s and is 1360 light years away

This is a total of 20 hours of exposure time thru my telescope over several nights in my backyard just outside of austin texas

According to Wikipedia —The Dumbbell Nebula was the first such nebula to be discovered, by Charles Messier in 1764. It is at a distance of 1360 light-years.

"For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

When we use powerful telescopes to look at distant objects in space, we are actually looking back in time."

we launched the voyager space craft 49 years ago in 1977.
its traveling at over 10 miles a second.(38000 mph)
this november it will be 1 light day away from earth.
at this rate it will take over 17,000 years to go 1 light year. the closest star is 4 light years away
