On June 20, 1670, a new star appeared in the evening sky that gave 17th century astronomers pause. Eventually peaking out at +3rd magnitude, the ruddy new star in the modern day constellation of Vulpecula the Fox was visible for almost two years before vanishing from sight.
The exact nature of Nova Vulpeculae 1670 has always remained a mystery. The event has often been described as a classic nova… but if it was indeed a garden variety recurrent nova in our own Milky Way galaxy, then why haven’t we seen further outbursts? And why did it stay so bright, for so long?
Now, recent findings from the European Southern Observatory announced in the journal Nature this past March reveal something even more profound: the Nova of 1670 may have actually been the result of a rare stellar collision.
...
ESO researchers used an instrument known as the Atacama Pathfinder EXperiment telescope (APEX) based on the high Chajnantor plateau in Chile to probe the remnant nebula from the 1670 event at submillimeter wavelengths. They found that the mass and isotopic composition of the resulting nebula was very uncharacteristic of a standard nova event.
A best fit model for the 1670 event is a rare stellar merger, with two main sequence stars smashing together and exploding in a grand head on collision, leaving the resulting nebula we see today. This event also resulted in a newly recognized category of star known as a “red transient” or luminous red nova.

Purty, purty.
"Yes, dear?"
"Why do the FR Mods delete all the astronomical threads about the planet Uranus?"
Indeed.
Dang that looks Saaaaweeet
That’s Not cho cheese
my mom had an ltd with a 429 she took most of the hot rodder freaks by surprise
Interestingly, the Datsun Fair Lady sports cars were marketed outside Japan as Datsun Sports.
I tried to jazz-up my old VW Beetle with parts from a JC Whitney catalog.
And I was about as successful in that effort as Hillary would be as a pole dancer.
But Three Dog Night’s ‘Golden Biskits’ on reverb speaker was pretty cool.
440 Hemi Six Pack. Hot Rod much? ;D)
I had 1191 cc’s—or 40 HP—of whistling Teutonic power in the back-end of of my Wolfsburg Road Warrior.
I’ll never forget ‘rowing’ through the Rockies while those valves clicked, occasionally hopping out and pushing.
Take a 426 Hemi, bore it .070, get suitable pistons, obtain an old Edelbrock Rat Roaster manifold, (huge open-plenum manifold for the Hemi), machine a top plate to accept Holley Six Pack, score the Holleys, dump it off, breath delicious tire smoke.
WHAMO...you got yourself a 440 Hemi Six Pack!
Those were the days! After getting married I traded my legal B/MP Fairlane for a Pinto. I almost got run over the first time I tuned into traffic. The power of the Pinto was alarming. I feel your pain.

Red Nova.................
Not RED........................
It would be way cool to see one of these, but I doubt I have that many years left.
