- Moon’scapes (2/28/2020) - There’s no denying that it’s been a rough week for many Earthlings. On the other hand, it’s been a great week for anyone who spends their time more preoccupied with the Moon than with more earthly concerns. That’s because there’s a treasure trove of news about our lunar realm. For example, NASA’s Goddard Media Studios … Continue reading Moon’scapes
- Lunar Landings (7/19/2019) - Saturday, July 20th is the 50th anniversary of the Apollo 11 Moon Landing, and there’s a massive media blitz surrounding the occasion. Pretty much every major news outlet is covering it in some way, and it’s no surprise that NASA is leading the publicity frenzy. On Friday at 1 p.m. (EDT) NASA is broadcasting 50 … Continue reading Lunar Landings
- Space Rocks! (1/4/2019) - It was a fantastic holiday season for space fans! In fact, there was so much going on, it was almost impossible to keep up with it all. According to your news sources and interests, you have probably heard about at least some of the amazing things that happened, but chances are you haven’t heard about … Continue reading Space Rocks!
- 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

- Apollo rock samples capture key moments in the...on February 25, 2021 at 1:25 pm
Volcanic rock samples collected during NASA's Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon's iron core, as well as the crystallization of the lunar magma ocean -- the sea of molten […]
- Scientist proposes a new timeline for Mars...on February 11, 2021 at 7:44 pm
A scientist has updated Mars chronology models to find that terrains shaped by ancient water activity on the planet's surface may be hundreds of millions of years older than previously thought. This new chronology for Mars, based on the latest dynamical models for the formation and evolution of the […]

The total amount of data generated worldwide is expected to reach 175 zettabytes (1 ZB equals 1 billion terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the stack would be 23 times the distance to the moon. There is an urgent need to develop storage technologies that can accommodate this […]

Vanderbilt paleoclimatologists using pioneering research have uncovered evidence of ancient climate "whiplash" in California that exceeded even the extremes the state has weathered in the past decade. Their findings present a long-term picture of what regional climate change may look like in the […]

Beyond Earth, the general scientific consensus is that the best place to search for evidence of extraterrestrial life is Mars. However, it is by no means the only place. Aside from the many extrasolar planets that have been designated as "potentially-habitable," there are plenty of other candidates […]
