Planet GJ1214b remembered

Back in December of 2009 I noted the discovery of a particular exoplanet that might have water, which would make it a candidate for an ‘Earth-like’ planet and therefore a candidate for having life. [SciTechStory: Another Earth: Will we even remember the planet GJ1214b?] I wondered if it’s completely forgettable name would have any meaning […]

This is an update: Gliese 581g is a fertile temptress

In case you hadn’t seen the news: A planet has been discovered – Gliese 581g (a bewitching name) – in orbit around a red dwarf (not the UK version) at ‘just the right distance’ (called the Goldilocks Zone because it’s not too hot and not too cold) to support life. [Here’s SciTechStory’s post: Another Gliese […]

Another Gliese 581 exoplanet: “Most potentially habitable yet”

The first planet orbiting the red dwarf star Gliese 581 was discovered in 2005. Since then, five more have been added. There are now three planets in this system with the tag “could be habitable.” The most recently verified is Gliese 581g, which has the distinction of sitting more or less in the middle of […]

It’s big, it’s temperate; it’s a normal planet: CoRoT-9b

To-date a little more than 400 planets outside of our Solar System have been discovered. A new planet has just been added to the list, CoRoT-9b, and it’s special. It’s a big planet, a gas giant like Jupiter and Saturn. However, its orbit is close to the star (unlike Jupiter and Saturn) so it has […]

New telescope finds planet near Sun-like star

The search for planets other than those in our own solar system (exoplanets) has been going on since the early 1990’s. Most of the searches and discovery of planets have been done by indirect means, for example, catching the shadow of a planet as it transits the local star, or detecting the perturbation in the […]
