...and likewise, is there a category for youngest star?
Hmmmmm... might have to pick a specific date for that record.
Edit: Haven't spent a lot of time looking for young stars (yet), but I did notice this young pup has the age in years down to three decimal places. My math makes that to about just under 9 hours, yet the advancing clock does not change its age. :o So no need for stating a specific date at time of discovery.
Wait a second... that red supergiant I posted just above is under 39,000 years old! I need to pay attention...
