Welcome to another scintillating riddle.  Okay, maybe “scintillating” isn’t the correct word, but I feel like patting myself on the back today.

On this day in 1915 Pluto was photographed for the first time.  Of course, nobody realized they had photographed the dwarf planet, and it was officially discovered 15 years later.

Ready now for your riddle?  I have a nice one lined up for you today.  Get your neurons fired up; you’re looking for something in the real world.

Found on a constellation card published in London in 1825

This is a modern discovery.

You’re looking for a different kind of Diva…

…and she’s not alone.

Some people say this is like a smoking chimney.

Others say it’s a ticking bomb.

It’s also been likened to a gun barrel pointed right at Earth.

It contributes to the formation of a shape very common in nature.

We are watching this Diva’s violent death throes, and the death throes of its companion.

In astronomical terms, this object is in our back yard.

That should do it.  You know where to find me, so come on and talk to me.
