I'm a 50+ year urban astronomer.
I'm also an ex-editor of the Royal Astronomical Society of Canada's, Toronto Center newsletter 'Scope. Trained in meteorology I spent several years in Canada's extreme high-arctic launching weather balloons. I later worked for the National Research Council's Space Research Facility launching scientific balloons some exceeding 100 meters in diameter. I was also part of the Launch Team of Canada's scientific rocket program participating in 35 sub-orbital launches. The program studied the edges of the atmosphere and the near-Earth space environment to 1,200km altitude.
Now retired I reside near the center of heavily light-polluted Toronto and its five million residents. It is from here I pursue astro-imaging from a 9th-floor balcony using a camera-equipped 20cm SCT telescope and still marveling at the heavens.

Using calculators you can input your own values to calculate the number of possible ascension species, or even Earth-like planets in our galaxy. It will even calculate their estimated distances from Earth in light-years.
