| How small cosmic seeds grow into big stars Posted: 26 Feb 2014 04:49 AM PST New images provide the most detailed view yet of stellar nurseries within the Snake nebula. These images offer new insights into how cosmic seeds can grow into massive stars. Stretching across almost 100 light-years of space, the Snake nebula is located about 11,700 light-years from Earth in the direction of the constellation Ophiuchus. |
| 'Super-Earths' may be dead worlds: Being in habitable zone is not enough Posted: 26 Feb 2014 04:49 AM PST In the last 20 years the search for Earth-like planets around other stars has accelerated, with the launch of missions like the Kepler space telescope. Using these and observatories on the ground, astronomers have found numerous worlds that at first sight have similarities with the Earth. A few of these are even in the 'habitable zone' where the temperature is just right for water to be in liquid form and so are prime targets in the search for life elsewhere in the universe. New results suggest that for some of the recently discovered super-Earths, such as Kepler-62e and -62f, being in the habitable zone is not enough to make them habitats. |
| Glimmer of light in the search for dark matter Posted: 26 Feb 2014 04:48 AM PST Astrophysicists may have identified a trace of dark matter that could signify a new particle: the sterile neutrino. Another research group reported a very similar signal just a few days before. |
