Kepler to Investigate Newly Discovered Nebula 38
derGoldstein writes with an article in DigitalTrends: "An amateur astronomer recently discovered what has been confirmed to be one of the best looks yet at a planetary nebula, the last, gassy breath of a dying star. The nebula, named Kronenberger 61 after the enthusiast who discovered it, will offer insights into the future and death of our own sun."

The pretty picture in TFA is caused by the nebula being lit up by radiation (mainly ultraviolent) from the dying star at the center. As the star dies from running out of stuff which is easy to efficiently fuse in the core, the star undergoes contractions and expansions which push the outer layers away to form a nebula. The term "planetary nebula" is a bit misleading- they are called that because they look like planetary discs if one looks for them in a small telescope. Phil Plait has a pretty good summary of what we are looking at - http://blogs.discovermagazine.com/badastronomy/2011/07/25/a-glowing-bubbly-bauble-in-space/ [discovermagazine.com]

Ultraviolent radiation? Awesome!

While that's a nice story, it's probably mostly incorrect. Most planetary nebulae like this are created when a massive Population II star (over 120 solar masses) that formed in a metal-poor region that was usually deposited by a population III star, explodes in a pair instability supernova [wikipedia.org]. This is a destructive explosion that usually completely obliterates the original star in one blast, having converted up to a fifth of its mass into iron or higher elements. It isn't some pulsing thing that happens ove

It's weird to have Kepler to investigate it
Exactly because Kepler looks at the star, and through its variations detects planets.
No star, what's Kepler supposed to do?
Also, it doesn't zoom on the subjects, it examines several at once.
By all means point Hubble at the Nebula, not Kepler, unless I'm missing something

Great! Now it makes sense
But I supposed this is for a 2nd stage Kepler observation, (unless it's already in its field)

Now we're back around, full-circle, to where you still haven't explained why you have software installed if you don't like said software. I suggested masochism because it is a theory that neatly explains the facts.
Simple, because removing it removes things I don't want removed
Well, fixed that and now PA is gone.

I guess on a terraforming planet, this would be the start of getting some real self sustaining atmosphere and biological movement.....next step would be single cell organisms appearing, and so on....might be the next earth in a few million years if the moon is able to sustain enough rainfall...
