Epsilon Eridani by digital_drew on Flickr.
Via Flickr:
Epsilon Eridani is an orange dwarf located 10.5 light years away. The star is moderately young, at an estimated age of 500 million years. Its circumstellar environment may be reminiscent of conditions in our own solar system four billion years ago. The Epsilon Eridani system has at least two asteroid belts, thick zodiacal dust, as well as an outer disk of icy material. Evidence suggests it has at least two gas giant planets. -

An Oxbow, or Ox-bow, lake is a U-shaped body of water named for the distinctive curved shape resembling the yoke of an oxen. This is one of the many Oxbow lakes in the Cuckmere Valley in East Sussex, England. It’s a descriptive name, rather than a place name. (Post dedicated to last-nigh-on-earth, who brought up the topic)

Crappy cell phone pictures from a geology trip the other week. Might as well use the tumblr for all of the pointless stuff I feel like sharing. Wish I’d had a camera that could’ve done some of the things I saw justice.

At the end of the last ice age, around 11,500 years ago, our planet entered the Holocene, an epoch of climatic stability and warmth. People came out of their caves and took advantage of the new conditions; they started farming and settling in villages and towns, which led to development of cultures and the rise of entire civilizations.
However, since the industrial revolution, human activity has accelerated and become so profound and global that many scientists think we have pushed the planet across a new geological boundary, into what some are calling the Anthropocene (which literally means the “age of man”). Now geologists are considering whether to formally define the new age, recognizing it in the same way as the Jurassic, Cambrian, or Holocene.
The photo is of Bingham Mine, the world’s largest open pit mine (copper), located outside of Salt Lake City and clearly visible from the International Space Station. Is is still growing and in operation today.

Most people consider Mt. Nyiragongo to be the world’s most violent volcano.Unlike eruptions in Hawaii which are relatively slow and could be outran, Mt. Nyiragongo’s steep slope causes lava to flow as fast as 60 mph!
