Check out this recent report from NASA on an exoplanet named Fomalhaut b, which orbits a 200-million-year-old star [10+08] called Fomalhaut, every 872 years [10+02]: “A second look at data from NASA’s Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named [...]
Discovery News reports that “Wisps of volcanic gas, rather than photosynthesis, may energize rare microbes eking out an existence on the Martian-like flanks of the tallest volcanoes in South America’s Atacama Desert. This newly discovered handful of bacteria, fungi and rudimentary organisms called archaea [roughly 80 micrometers, or 10-5 meters in diameter and 200-600 micrometers, [...]
“Visible light” corresponds to a wavelength of 400 – 700 nanometers or 10-07 meters. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. You’ll notice that the color pink doesn’t appear anywhere on that list. Recently, there has been debate as to whether or not the color pink [...]
According to a recent article in Slate, researchers believe the evolution of human pregnancy may be linked to a parasitic DNA (10-07) that infected our ancestors by replicating itself throughout their genomes 100 million years ago (10+08). Scientists studied the uterine cells of three contemporary mammals, specifically opossums, armadillos and humans. Their goal was “… [...]
Photographs of Krypton Gas and Krypton Plasma: From Jefferson Lab Left – Krypton gas in a sealed glass tube. Center – A Tesla coil is used to excite the atoms in the gas, creating a plasma. Right – A longer exposure of the plasma with all of the room’s lights turned off. —————————————————————————— Of course, [...]
1/93 = .0107526 That is a small number but in the world of nanotechnology it would be a giant! Yesterday’s blog was about the idea of exploring outer space – ever bigger powers of 10. Now the pendulum will swing the other direction. Tomorrow’s blog will be about exploring the tiny world of nanotechnology – [...]
