Carbon Worlds Likely Bone-Dry and Lifeless

  Planets rich in carbon, including so-called diamond planets, may lack oceans, according to NASA-funded theoretical research.  This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in [continue reading]

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]

Solar Systems Without Jupiters Mean Massive Comet Belts

  Using ESA’s Herschel space observatory, astronomers have discovered vast comet belts surrounding two nearby planetary systems known to host only Earth-to-Neptune-mass worlds. The comet reservoirs could have delivered life-giving oceans to the innermost planets. Artist impression of the debris disk and planets around the star known as Gliese 581, superimposed on Herschel PACS images [continue reading]

Potentially Habitable Exoplanet Found in our Neighborhood

  An Anglo-German team of astronomers has discovered a new planet orbiting a nearby star at just the right distance for an Earth-like climate that could support life. This artist’s impression shows HD40307 g in the foreground (on the left hand side), with its host star HD40307 and two other planets in the system (on [continue reading]

Alien Life Might be Able to Survive  Under Extreme Conditions

  Astronomers have discovered a veritable rogues’ gallery of odd exoplanets — from scorching hot worlds with molten surfaces to frigid ice balls. And while the hunt continues for the elusive “blue dot” — a planet with roughly the same characteristics as Earth — new research reveals that life might actually be able to survive on [continue reading]

Habitable Planets Could Be Much More Widespread Than Thought

  A new scientific model to understand the amount of our Universe which is habitable developed by University of Aberdeen scientists was announced on September 7 at the British Science Festival, one of Europe’s largest science festivals that regularly attracts over 350 of the UK’s top scientists and speakers to discuss the latest developments in science with [continue reading]
