Gaia space telescope discovers 55 'runaway' careening away from stellar cluster at 80 times the speed of sound

3. Checking the math:

At 62,000 mph, allegedly going 80 times the speed of sound on earth, I came up with speed of sound on earth as 775 mph. Now that number seems a bit high but it varies with a number of factors. Altitude above sea level (i. e. Density of air at a certain height), temperature of the air, and humidity; and whether you want average in speed of sound in seawater (oceans, lakes, etc).

So none of that bit about calculations takes away from that report of unique and awesome phenomena displayed in that specific galaxy. It's kinda mind-blowing. Their relatively short lifespans are also fascinating. But seem difficult to understand.
