Stream gaging sure was a dapper occupation at the turn of the century! Here’s the various techniques United States Geological Survey hydrologists used to measure current without even dipping a toe ...

A research team led by Tomoro Sashida and Tomoharu Oka (Keio University) has succeeded in precisely measuring the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located ...

AbstractWe describe a robust technique based on the ULySS IDL code for measuring velocity dispersions of galaxies observed with the MMT’s fiber-fed spectrograph, Hectospec. This procedure is ...

Archery and target shooting with firearms and air guns are just a few of the many sports and pastimes that involve high-speed projectiles. Try this measurement technique. Archery and target shooting ...

There seems to be a discrepancy between measurement of the expansion of the Universe using radiation in the early Universe and using nearby objects. Researchers have now contributed to this debate by ...

Astronomers have precisely measured the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located in the constellation of Aquila, approximately 10,000 light-years away ...
