How to Picture the Size of the Universe


Quote:
Space, as Douglas Adams once so aptly wrote, is big.

To try imagining how big, place a penny down in front of you. If our sun were the size of that penny, the nearest star, Alpha Centauri, would be 350 miles away. Depending on where you live, that’s very likely in the next state (or possibly country) over.

Attempting to imagine distances larger than this quickly becomes troublesome. At this scale, the Milky Way galaxy would be 7.5 million miles across, or more than 30 times the distance between the Earth and the moon. As you can see, these are rather inhuman dimensions that are almost impossible to really get a sense of.

New research into Earth's paleoclimate history by NASA's Goddard Institute for Space Studies director James E. Hansen suggests the potential for rapid climate changes this century, including multiple meters of sea level rise, if global warming is not abated.

As parts of Central America and the U.S. Southwest endure some of the worst droughts to hit those areas in decades, scientists have unearthed new evidence about ancient dry spells that suggest the future could bring even more serious water shortages. Three researchers speaking at the annual meeting of the American Geophysical Union in San Francisco on Dec. 5, 2011, presented new findings about the past and future of drought.

2010 Spike in Greenland Ice Loss Lifted Bedrock, GPS Reveals


Quote:
An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons -- and large portions of the island's bedrock rose an additional quarter of an inch in response.
