It’s a small chance, but having a small chance of something wiping out all of life on a planet still seems like too much.
We might be too early for the party. Darn!
Exoplanet GJ581d is the first potentially habitable world astronomers have discovered, but some astronomers believed that the planet wasn’t actually there – it was all an observational flaw mixed with some noise in the signal. However, British researchers recently released a study which confirms that the planet does exist and further underline the matter of habitability. This is one of the planets outside our solar system most likely to harbor life.
Too close for comfort – a team of astronomers from the US, Europe, Chile and South Africa concluded that a dim star passed through the Oort cloud, our solar system’s distant cloud of comets. The star missed the Earth by less than one light year, and passed five times closer than the current closest star, Proxima Centauri. In a paper published
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.
A new study has concluded that virtually all red dwarfs, the stars which make up at least three quarters out of all the stars in the Universe, have planets orbiting them. The study suggested that habitable-zone super-Earth planets (where liquid water, and therefore life as we know it can exist) orbit around at least a quarter of the red dwarfs
ESA’s XMM-Newton space telescope has found a star and a black hole that orbit each other at the whopping rate of once every 2.4 hours. Basically, the star orbits the black hole at 2,000,000 km/hr. The black hole here is 3-4 times heavier than the Sun, while the red dwarf has a mass just 20% that of the Sun. Because
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
One of the most outstanding dreams astronomers and other scientists hope to accomplish is to someday encounter proof that extraterestrial life exists. Intelligent life might be extremely far off, however microbiological life should without a doubt be present elsewhere other than our planet or solar system. For life to blossom, however, the right conditions have to be met, and one
A supernova is a stellar explosion of cosmic proportions, that often can outshine the entire galaxy it is located in, before fading away in a matter of weeks or months. During this short period however, supernovae emit as much energy as the Sun emits during its entire life span – it’s the same kind of phenomena that researchers from the
