Red Dwarfs Could Strip Away Protection of Their Planets

  Red dwarfs are the commonest type of stars, making up about 75% of the stars in our Galaxy. They are much smaller and much less massive than our Sun and for that reason a lot dimmer. If planets are found around these stars, then given the number of red dwarfs, life could then be [continue reading]

White Dwarfs "polluted" with Planetary Debris

  The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet formation is common in clusters, [continue reading]

Looking for Habited Planets Around White Dwarfs

    TAU finds white dwarf stars may hold the key to detecting life on other planets   Because it has no source of energy, a dead star — known as a white dwarf — will eventually cool down and fade away. But circumstantial evidence suggests that white dwarfs can still support habitable planets, says [continue reading]

Finding Some 100 Billion Earth-Like Planets by a New Technique

  Researchers at The University of Auckland have proposed a new method for finding Earth-like planets and they anticipate that the number will be in the order of 100 billion. Most of the discovered extrasolar planets lie within 300 light-years of the Solar System. Image Credit: NASA/JPL The strategy uses a technique called gravitational microlensing, currently [continue reading]

Super-Sized Twin of our Solar System Contains Also Water

  Glimpses of a giant alien planet may help to answer questions about its origins and those of our own Solar System.   A team of astronomers, including Quinn Konopacky of the University of Toronto’s Dunlap Institute for Astronomy & Astrophysics, have made the most detailed examination yet of the atmosphere of a Jupiter-like planet [continue reading]

Evidence for E.T. Might Come from Dying Stars

  Even dying stars could host planets with life – and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers found that we could detect oxygen in the atmosphere of a white [continue reading]
