Earth’s surprise Neighbor Hints at
Exoplanet Abundance
AROUND THE TIME
Earth formed, a slightly larger world coalesced by a much different star. Our
sun was a steady, bright-yellow dot in its neighbor’s night sky, but the two
stars and likely their planets evolved along much different paths. The other
star was a red dwarf, dim and cool and prone to violent outbursts. It rained
harsh radiation onto its world’s surface, and lit it with the soft orange hue
of a perpetual sunset.
That ruddy star was Proxima
Centauri, our sun’s nearest stellar neighbor, just 4.2 light-years away. The
star’s violent emission long obscured the planet orbiting it. Thanks to a
monthslong observing campign, however, astronomers deduced and finally
confirmed the planet’s existence in August. Dubbed Proxima , it sits smack in
the middle of its star’s habitable zone, where luquid surface water and thus
possibly life cold exist.
Incredibly, the planet’s ghostly
signal was hidden in plain sight for decades. In 2014, the international
collaboration of scientists known as the Pale Blue Dot as the Pale Red Dot
named in homage to Carl Sagan, who described Earth as a Pale Blue Dot banded
together after astronomers noticed the periodic signal of a possible planet
coming from the star every 11.2 days.
For months last year, the team kept
a near-constant vigil on Proxima Centauri, looking for tiny wobbles caused by
the pull of an orbiting planet. An analysis of this new data, as well as a
simultaneous analysis of the decades-old observations, led to the planet’s
confirmation, published in Nature.”You
take the old data and the new data, and you combine everything together, and
then the significance of the detection goes sky high very, very
significant,”says Queen Mary University of London astronomer Guillem
Anglada-Escude, who led the discovery team. The team had to be careful because
these small, violent suns have fooled astronomers before. Red dwarfs, by far
the most abundant type of star in the galaxy, can create planet-like signals
during their powerful flares.
