Sentences with phrase «only habitable planet»

Since Omega Centauri is thought to be Kapteyn's star place of origin, scientists estimate that its planets must be approximately 11.5 to 12 billion years old, thus making Kapteyn b not only the oldest known possibly habitable exoplanet to date, but, along with Kapteyn c, the first that might have originated from another galaxy, outside of the Milky Way.

It's great to say that the universe is 14 billion years old, or that Voyager 1 is now flying towards one of the nearest habitable planets, but it's only when we put things in human terms do we truly appreciate the scale of the universe.
When looking for habitable worlds, it helps to find a star that has similar qualities to our sun as it's the only star known to have a planet orbiting that's packed with life.

«Planet e is in the habitable zone only if we make very generous assumptions.
Planet f initially looks more promising, but modeling the evolution of the star makes it seem probable that it has only moved into the habitable zone recently as Tau Ceti has gotten more luminous over the course of its life,» explains astrophysicist Michael Pagano, ASU postdoctoral researcher and lead author of the paper appearing in the Astrophysical Journal.
The system is particularly exciting, not only because of its proximity to our planet, but because it has three planets within the habitable zone, where...
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).
