APOD 2.1

water ice detected under the Lunar surface Ice was thrown up from the impact of a satellite from earth, and the resulting analysis suggests we may be able to find a much higher volume of H2O on the moon than previously thought. Whether or not we'd be able to mine it is unknown, but I would be interesting to see if we could get people onto the moon regularly. Waving my science fiction nerd flags here, human expansion into space would be interesting to see, if it's possible. And any settlement on the moon would be able to house a telescope that can see in all wavelengths of light. No atmosphere here.

Johannes Regiomontanus.

Johannes Müller von Königsberg was born on June 6^th, 1436. He adopted “Regiomontanus” as a pseudonym, derived from his birthplace who’s meaning was “King’s mountain”. Nothing is known of his early life, but in April of 1450 he enrolled in the University of Vienna. Two years later, in January, he graduated with a bachelor’s degree. Afterwards he held lectures in optics and ancient literature. He also built astrolabes and even a portable sundial for Pope Paul II.

In 1457 he became a colleague of Peuebach. He was persuaded to create a “briefer and more comprehensible” Latin version of Ptolemy’s Mathematical Syntaxes, but had died after finishing book IV and on his deathbed asked Regiomontauns to finish it. He returned to Rome in November of 1461, and had finished the epitome there. However, if was never printed until twenty years after the death of Regiomontanus. Despite this folly, the book contributed greatly to modern science, because in addition to translating the book Regiomontanus also included so critical analysis, revisions, and other observations to it. Errors in Ptolemy’s work regarding the moon were pointed out in the translation, and they would later influence Copernicus and his work.  

Over the next four years, Regiomontanus lived and worked in the home of Cardinal Bessarion. There he wrote De Triangulis Omnimodus (one of the first textbooks on trigonometry) and Epytoma in almagesti Ptolemei. In 1471 he moved to Nuremburg in Franconia. There he became famous for constructing the first observatory in Germany.

In 1475 he returned to Rome to work on calendar reform. En route he published his "Ephemeris" in Venice. He died in July of 1476, Most likely by the Plague, but there were rumors that he died by assassination.

APOD 1.8

It came from the Sun Oh dear. I just know the 2012 doomsday fanatics are going to take note of this one. The Sun is three years away from reaching "solar maximum" which sounds catastrophic but it happens every 11 years if wikipedia is to be believed. expect more sunspots in late 2012 to early 2013, but other than that we're not expected to die yet. The Mayans didn't even say 2012 was doomsday, the Mesoamerican long-term calendar just kinda stops there. I wish I was old enough to comprehend the scope of human stupidity leading up to 2000. Silliness. The Coronal mass ejection depicted here is actually cooler than the sun's surface anyway (it's just a sun-fart.)

Saturn: light, dark, and strange
Even with explanation the image is difficult to decipher. The rings don't appear to match up. it has to make sense somehow, yet I cannot piece together the rings. Bizarre. I'd love to see the image in color, as it might better demonstrate what's going on. Or get more confusing, depending on how much the cosmos want to mess with our heads.

APOD 1.6

Io in true colorOne of the Galilean satellites is turning itself inside out from ridiculous amounts of volcanic activity. The heat causing the eruptions is in turn caused by the friction of Jupiter's "tidal gravity." Somewhat less hospitable than the planet from the last post. Good for mining sulfur and silicone though.

APOD 1.5

Zarmina's world
more officially known as Gliese 581g, this planet is relatively close by, and may actually be hospitable. Will our race expand to other planets? is there life already there? Should be interesting to see what becomes of this discovery. Especially so close to us.
