An excerpt from Nancy Atkinson’s “Twin Spiral Galaxies Dance Together” in Universe Today “… The image was obtained, appropriately enough by the Gemini South telescope in Chile using GMOS, the Gemini Multi-Object Spectrograph. These two nearly identical spiral galaxies are in Virgo, 90 million light years distant, in the early stages of a gentle gravitational [...]

What moves at 300 million meters per second? That’s the speed of light! From Wynne Parry’s “Why The Speed of Light Matters” in Live Science Credit: Willem Dijkstra, Shutterstock Einstein’s theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second), as a cosmic speed limit. Some [...]

Consider this: after recycling your soda can, it takes as few as 60 days (10+01) for it to appear on your grocery shelf again. In addition, “The energy you save by recycling a single aluminum can will run a TV for three hours,” according to recyclingfacts.org. Given that decomposition in a landfill takes as long [...]

Avogadro’s Number is 6.0221415 X 1023 which is also quantified as N A. “Avogadro’s number, N A , is the fundamental physical constant that links the macroscopic physical world of objects that we can see and feel with the submicroscopic, invisible world of atoms. In theory, N A specifies the exact number of atoms in [...]

Electron rest mass from Table of Physical constants “The electron rest mass, symbolized m e , is the mass of an electron as measured when its speed is zero relative to an observer. The electron has extremely small mass – it’s almost 2000 times less massive than the proton — at approximately 9.10956 x 10 [...]
