Yellowstone National Park is a great, beautiful, tourist site where family and friends enjoy spending a few hours. But scientists caution that Yellowstone might explode someday. The Los Angeles size underground volcano gives a few "breaths", causing the ground to rise dramatically. According to National Geographic, the last eruption was "a thousand times more powerful than Mount St. Helen's 1980 eruption." Scientists explain the volcano will erupt soon, and it is estimated the ashes will go up to 25 feet high! Chemicals and modern technology are a few things I enjoy in science, but natural disasters and ecology helps scientists understand how the earth was like without electricity and chemical interruptions. Overall, we learn a lot from natural science.
From http://news.yahoo.com/s/ap/us_sci_space_blob, it is informed that there is a green blob of gas giving birth to new stars. The stars form at remote parts of the universe, though, where most stars don't normally form. The blob was first discovered in 2007 by Dutch teacher, Hanny's Voorwerp (HAN'-nee's-FOR'-vehrp). NASA released the Hubble telescope photo of the green blob recently on January 10, 2011. When elementary school teacher Hanny van Arkel first saw the blob, he called it a "small blue smudge", but now it's seen as a bright green. The group of stars is approximately 650 million light years away and our own Milky Way Galaxy is about the same size as the blob. Astronauts has visited the blob, and I find it fascinating of our generation finding out new information in the most unknowns places.
