The planet was found around the most common type of star in the Milky Way — a red dwarf.

Although Kepler and Corot are focusing on sunlike stars that could support true analogues of Earth, much of the action at ground - based telescopes is concentrating on red dwarf stars, for the simple reason that planets are easier to find there.

Red dwarf stars, which are by far the most common stars in our galaxy, were once considered unlikely places to find Earth - like planets, but new studies contradict that view.

The planet, dubbed Gliese 581 g, was found to orbit a dim, red dwarf star every 37 days, according to an analysis by Steven Vogt of the University of California, Santa Cruz, Paul Butler of the Carnegie Institution of Washington in DC, and their colleagues.

SS: TESS will do an all - sky survey to find rocky worlds around the bright, closest M - stars [red dwarfs that are common and smaller than the sun — and therefore more likely to reveal the shadows cast by planets], about 500,000 stars.

After years of scrutinizing the closest star to Earth, a red dwarf known as Proxima Centauri, astronomers have finally found evidence for a planet, slightly bigger than Earth, well within the star's habitable zone — the range of orbits in which liquid water could exist on its surface.

«We find that variations in the UV emissions of red - dwarf stars have a potentially large impact on atmospheric biosignatures in simulations of Earth - like exoplanets.

An estimated 58 billion red dwarf stars live in our galaxy, and it is known that most will play host to planets, so when the Thirty Meter Telescope goes online, astronomers may be on the verge of finding that highly sought after biosignature fingerprint.

A new member in a family of planets circling a red dwarf star 20 light - years away has just been found.

Recent statistics indicate that over a fourth of Sun - like stars and roughly a half of red dwarfs in our Milky Way Galaxy have been found in multi-star systems — around 44 percent of of spectral types F6 to K3 and possibly declining to one third to one fourth of very dim type M stars that are difficult to observe (Raghavan et al, 2010; Charles J. Lada, 2006; and Duquennoy and Mayor, 1991).

We found that brown dwarfs are similar to the gas giants in the Solar System (in that they have zonal circulation), but that they are more like Neptune and less like Jupiter (their brightness variations are driven by large - scale waves in zones rather than Great Red Spot - like storms as in Jupiter).

Abstract: We report the discovery of an unusually red brown dwarf found in a search for high proper motion objects using WISE and 2MASS data.

We only have limited resources and technology available to us and currently looking at nearby red dwarfs is a good opportunity to find exoplanets which we can hopefully start to characterise in the near future.

So, now that we know a tiny rocky world orbiting a tiny star 39 light - years away can support its own atmosphere, the future could be bright for finding evidence of alien biology on super-Earths orbiting red dwarf stars.

Nevertheless, if intelligent, technological life can develop on a planet around a red dwarf inside a globular cluster, then it would find interstellar travel far more feasible than we do.

The liquid water habitable zone provides the best observational constraint on where we would expect to find planets that could support conscious observers like us, and this study examines the probability of finding oneself on a planet in the habitable zone of a yellow dwarf star, compared to a red dwarf.

The statistics for this aspect of the problem suggest that our existence around a yellow dwarf star today, compared to a red dwarf star in the future, might be a slight statistical anomaly — perhaps on the order of finding oneself born ambidextrous or with perfect pitch.

«Having these combs routinely available as a modest add - on to current and future instrumentation really will expand our ability to find potentially habitable planets, particularly around very cool red dwarf stars,» he says.

If these red dwarf stars will eventually become the predominant place for conscious observers to develop, then why do we not instead find ourselves around a red dwarf star billions or trillions of years into the future?

But if these much smaller stars are more commonplace, then why do we find ourselves around a yellow star like the sun, instead of a red dwarf?

Yes, it is an incredible stroke of luck to find a small world orbiting a neighboring star, but as red dwarfs are the most populous type of star in our galaxy, the odds are that a handful may well have just the right ingredients to support a habitable atmosphere.

Now that this oddball star system has been discovered, astronomers hope to find more examples, so they can understand how massive worlds like NGTS - 1b evolve around tiny red dwarfs.

On March 28, 2012, astronomers working with the European Southern Observatory's HARPS instrument announced that super-Earths with habitable - zone orbits may be found in about 41 percent (within a range of 28 to 95 percent) of dim red dwarf (spectral class M) stars within 30 light - years of our Sun.

Previously discussed in a November 24, 2011 pre-print, the astronomers «surveyed a carefully chosen sample of 102 red dwarf stars in the southern skies over a six - year period» and found a «total of nine super-Earths (planets with masses between one and ten times that of Earth),» of which two orbiting within the habitable zones of Gliese 581 and Gliese 667 C. By combining all the radial - velocity data of red dwarf stars (including those without undetected planets) and examining the fraction of confirmed planets that was found, the astronomers were able to estimate the probable distribution of different types of planets around red dwarfs: for example, only 12 percent of such stars within 30 light - years may have giant planets with masses between 100 and 1,000 times that of the Earth (ESO news release; Bonfils et al, 2011; and Delfosse et al, 2011).
