- Get Lost in Space! (9/14/2018) - Way back in August, in anticipation of the start of a new school year, I set out to update the pages on this site related to space. Those pages tend to be popular among the teachers and students who use Cosma, and I happen to enjoy updating them, too. It sounded like a short, fun … Continue reading Get Lost in Space!
- Visioning Spacesteads (8/8/2018) - Space, the final frontier… Humans have been imagining what it would be like to setup homesteads and live in space for about as long as they’ve been imagining how to get there, but the process didn’t really take off until after we actually got there. Back in the 1970’s NASA dedicated some resources to the … Continue reading Visioning Spacesteads
- Octopuses from Space! (5/20/2018) - Did you hear the one about the octopuses from space? It sounds like the title of a cheesy sci-fi movie, doesn’t it? But it isn’t, this time, or at least, yet. Instead, it’s actually an oddball theory that’s been put forth in a recently published “scientific” article that’s getting quite a lot of buzz in … Continue reading Octopuses from Space!
- Umbraphiles (8/20/2017) - umbraphile : One who loves eclipses, often travelling to see them. — Wiktionary Yes, this is that obligatory post about “The Solar Eclipse” (NASA, Wikipedia). Of course, there had to be one — eclipses really are just too cool to ignore. You’ve already been bombarded with explanations of the science and history of eclipses, but … Continue reading Umbraphiles
- Moon+H2O=Moonbase? (7/25/2017) - One of the big science stories in the news right now is that Earth’s Moon has more water than scientists expected. This Newsy video is just one of the hundreds of stories flooding news feeds. This round of stories has been inspired by this article in Nature Geoscience. Remote detection of widespread indigenous water in … Continue reading Moon+H2O=Moonbase?

Moon : the earth’s natural satellite (see satellite 2a) that shines by the sun’s reflected light, revolves about the earth from west to east in about 291⁄2 days with reference to the sun or about 271⁄3 days with reference to the stars, and has a diameter of 2160 miles (3475 kilometers), a mean distance from the earth of about 238,900 miles (384,400 kilometers), and a mass about one eightieth that of the earth (often capitalized : usually used with the) — Webster
The Moon is an astronomical body that orbits planet Earth, being Earth’s only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). Following Jupiter’s satellite Io, the Moon is second-densest satellite among those whose densities are known. The average distance of the Moon from the Earth is 384,400 km (238,900 mi), or 1.28 light-seconds.
The Moon is in synchronous rotation with Earth, always showing the same face, with its near side marked by dark volcanic maria that fill the spaces between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth’s sky, after the Sun, as measured by illuminance on Earth’s surface. Its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have made the Moon an important cultural influence since ancient times on language, calendars, art, and mythology.
The Moon’s gravitational influence produces the ocean tides, body tides, and the slight lengthening of the day. The Moon’s current orbital distance is about thirty times the diameter of Earth, with its apparent size in the sky almost the same as that of the Sun, resulting in the Moon covering the Sun nearly precisely in total solar eclipse. This matching of apparent visual size will not continue in the far future. The Moon’s linear distance from Earth is currently increasing at a rate of 3.82 ± 0.07 centimetres (1.504 ± 0.028 in) per year, but this rate is not constant. — Wikipedia

Mysterious 'lunar swirls' point to moon's...
on September 6, 2018 at 4:33 pm
The mystery behind lunar swirls, one of the solar system's most beautiful optical anomalies, may finally be solved. The solution hints at the dynamism of the moon's ancient past as a place with volcanic activity and an internally generated magnetic field. It also challenges our picture of the […]

Around four billion years ago, the moon had a magnetic field that was about as strong as Earth's magnetic field is today. How the moon, with a much smaller core than Earth's, could have had such a strong magnetic field has been an unsolved problem in the history of the moon's evolution. A new model […]

A study simulating the final stages of terrestrial planet formation shows that 'hit-and-run' encounters play a significant role in the acquisition of water by large protoplanets, like those that grew into Mars and Earth. The results will be presented by Christoph Burger at the European Planetary […]
