Trick or treat? I’m dressed as a habitable planet.
For decades, researchers have studied our planet’s orbit with growing interest: is there something special about the way the Earth revolves around the Sun, is it a necessary condition for life to emerge? A team of researchers from MIT studied 74 Earth-sized exoplanets and reports that all of them have fairly circular orbits around their stars. Circular vs Eccentric The
Astronomers hunting for habitable Earth-like planets now believe that the best place to look is not around stars like our Sun, but rather around smaller, cooler stars—orange and red dwarfs. These are by far the most abundant stars in our galaxy, and all of them have at least one exoplanet.
After researchers surveyed data from the Kepler mission tasked with identifying possibly habitable planets outside our solar system they found that 6% of red dwarfs – the most common type of planets – are within this zone. This new adjustment would mean that the nearest Earth-like planet might lie just 13 light years away. Astronomers at the Harvard-Smithsonian Center for
As our search for alien planets improves and intensifies, astronomers are starting to pay more and more attention to one crucial aspect of alien planets: whether they fit into the ‘habitable zone‘ – the so-called Goldilocks area in which a planet is not too close and not too far from its star – just perfectly placed to support liquid life,
Astronomers have discovered five planets orbiting Tau Ceti, the closest single star that resembles our Sun in terms of temperature and luminosity. Finding our cosmic neighbors If the planets are indeed there and no error was involved in the study, then there’s a good chance one of them is the right distance from the star to sport adequate temperatures, liquid
The search for other planets gets more and more exciting and fruitful, and now, researchers have found an exoplanet which lies truly close to us – in cosmic terms. Alpha Centauri Alpha Centauri is the closest solar system to our own, at only 4 light years away, so finding an Earth-sized planet there really is a big thing, and it
A recently discovered planet is just about the right size and is in the right place to host life; as a matter of fact, astronomers seem quite sure it hosts life, and we’re talking more than microbes. Still, current technology doesn’t allow scientists to search for chemical markers of life. About 20 light years away, it revolves around a red
The hunt is on for finding other planets we can live on; this is probably the next step for us as a species, and may just be crucial, considering how things are developing on Earth. But we haven’t had much luck with that so far. Now, scientists are using a method which is claimed to be more precise in
