Nov 4, 2013 — A team of astronomers crunching data from the Kepler space telescope say 22 percent of Sun-like stars harbor Earth-like planets.
Oct 1, 2013 — Scientists publishing in Astrophysical Journal Letters say they've used space telescopes to record faint light from the distant planet to get a rough map of its atmosphere.
Jul 15, 2013 — Just 12 miles across, the little moon was discovered in photos taken by the Hubble Space Telescope. When scientists recently rejected Vulcan as the name for one of Pluto's moons, Star Trek fans complained. Naming conventions will bar Vulcan from being used for Neptune's moon as well.
Jun 5, 2013 — Last week NASA scientists put the space telescope Kepler in a kind of technological coma. The craft, designed to search for Earth-like planets orbiting stars in our cosmic neighborhood (within a few thousand light-years, that is), failed and seems to be unfixable. But it has left us with an undeniable legacy.
May 22, 2013 — Confronted with the amazing advances made by science, why do so many still cling to God as a creator? Could the answer be that we need to be created in order to be special? Or are we afraid of our own unique place in the Universe? Marcelo Gleiser knows what he thinks.
Apr 17, 2013 — Is the importance of life on Earth shrinking as science continually re-defines our world as a meaningless speck in an endless and uncaring Universe? Or is life here a precious thing that grows in importance with our ever-deepening knowledge of the Universe? Commentator Marcelo says it's the latter.
Feb 19, 2013 — The eye-popping, ear-splitting meteor streaking over Russia last Friday was an invitation to look up more often, to track the shooting stars we might see on any given night. These daily visitors to our planet put cosmic history into context, lighting up a past that is full of debris.
Feb 13, 2013 — Of the patriarchs of science, Kepler is the least known. This injustice should be rectified, for Kepler not only taught us about how the planets move in the sky but also how important it is to dream; and how equally important it is to make sure the data backs your dreams up.
Oct 31, 2012 — NASA's Kepler Mission has been spotting many "Earth-like" planets within our galactic neighborhood. But what fraction of these Earth-like planets are really like our planet? The more we learn about Earth's remarkable properties, the rarer our planet seems to be. And with it, the life it hosts.
Oct 16, 2012 — Astronomers have finally discovered a planet orbiting Alpha Centauri, the nearest star to the Sun. At a mere 4.4 light years away, scientists have long hoped that a planet would be found around this closest of stellar neighbors.
