(from nasa.gov)… A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes. They are […]
Summary: Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn’t the only force at work. Both turbulence and magnetic fields battle gravity, either by stirring things up or by channeling and restricting gas flows, respectively. New research focusing on magnetic fields shows that they influence star formation […]
from news.nationalgeographic.com… The Hubble Space Telescope’s recent images of giant balls of stars in a nearby galaxy… have astronomers puzzled as to the star balls’ origins… Multitudes of such “globular” star clusters, each filled with hundreds of thousands of the oldest stars in the universe, lie scattered around our own Milky Way and other galaxies. But […]

from ScienceDaily.com Summary: “A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space.” Organic conundrum in Large Magellanic Cloud — ScienceDaily.
from an article posted on sciencedaily.com in April 2013: Summary: A team of scientists has discovered two Earth-like planets in the habitable orbit of a Sun-like star. Using observations gathered by NASA’s Kepler Mission, the team found five planets orbiting a Sun-like star called Kepler-62. Four of these planets are so-called super-Earths, larger than our […]
From Sciencedaily.com… “Massive stars — those at least 8 times the mass of our Sun — present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller… Average stars like our Sun begin life as dense, but relatively low-mass concentrations of hydrogen, helium, […]
