orbit around at least a quarter of the

In 2006, astronomers discovered a very dim («mid-range»),
red dwarf companion to HD 189733 A of spectral and luminosity type M V. Observed at a separation of 216 AUs from Star A, the companion star has a clockwise

Discouragingly, a new study published
in The Astrophysical Journal suggests that
planets in orbit around red dwarfs may be subject to tremendously powerful and frequent solar flares, making it difficult — if not impossible — for life to emerge
in such systems.
The European Space Agency's Mars Express probe continues to image and study the surface of the
Red Planet and gather data about the Martian atmosphere today, nearly 10 years after arriving

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).
