This artist’s impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The double star Alpha Centauri AB also appears in the image between the planet and Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.

Earth-Like Planet Discovered In Habitable Zone Of Nearest Star

Amazing news! Today, a team of European astronomers announced the discovery of a potentially habitable planet around Proxima Centauri, the nearest star beyond the sun. That planet, called Proxima b, is at least 1.3 times the mass of Earth and squarely located within the star’s habitable zone, where temperatures are clement enough for liquid water…

Hubble Sees White Dwarf Zap Red Dwarf With Cosmic Light Saber

Can white dwarfs wield light sabers? Apparently the white dwarf star in the AR Scorpii system can.  In May 2015, a group of amateur astronomers from Germany, Belgium and the UK came across a star system that was exhibiting behavior unlike anything they had ever encountered before. Known as AR Scorpii, or AR Sco for short, the…

This artist’s impression shows an imagined view from the surface one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO’s La Silla Observatory. These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the Solar System. They are the first planets ever discovered around such a tiny and dim star. In this view one of the inner planets is seen in transit across the disc of its tiny and dim parent star.

Three Potential Earth-like Planets Discovered Around Nearby Star

Three new planets discovered around a tiny, faint star in the constellation Aquarius may be among the best places to look for evidence of extraterrestrial life. A team of astronomers led by Michaël Gillon of the Institute of Astrophysics and Geophysics at the University of Liege in Belgium studied the star, named TRAPPIST-1, and discovered it…

Nearby Red Dwarf Star Unleashes X100,000 Superflare

Sometimes big things come in small packages. Last April, DG CVn, a red dwarf star only one-third the size of the sun, cut loose with a flare 10,000 times more powerful than any solar flare ever recorded. The sun’s grandest was an X 45 on November 4, 2003 which happily was directed off its western…

Newfound Alien Planet Gliese 832c Reminds Us Of Home

An international team of astronomers, led by Robert A. Wittenmyer from Australia, report the discovery of a new potentially habitable ‘super-Earth’ around the red dwarf star Gliese 832 only 16 light years away in the constellation Grus the Crane. This is the second planet known to orbit the star. In 2009 astronomers discovered a cold, Jupiter-like world, Gliese…
