May 6, 2014 — When we think of life, we think of the Earth. But the universe may have other ideas. Commentator Adam Frank considers the case for life on planets around M-dwarf stars.
Mar 26, 2014 — The tiny world is a pink-hued ball of ice in an area of space once thought to be relatively empty. But the new findings hint of other small objects — and perhaps an unseen planet bigger than Earth.
Feb 26, 2014 — The space agency announces a stunning discovery, as the Kepler mission identifies 715 new planets that orbit 305 stars. The finding boosts the verified number of such planets by around 70 percent.
Jan 16, 2014 — Scientists hunting for planets that could support life have been too focused on finding places that resemble Earth, according to a report in the journal Astrobiology. The authors have come up with a list of traits that might make a planet "superhabitable."
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.
