There's no other way to put it: this is the historic first picture of a planet orbiting another star.
The star in question is a brown dwarf
(what some people unfairly call a failed star) called 2MASSWJ1207334-3932 - or 2M1207 for short - located about 230 light years from Earth. This false-colored infrared image shows the star as blue, and the planet red.
The planet, called 2M1207 b, has about 5 times the mass of Jupiter, and orbits the star over 8 billion km (5 billion miles) out, about twice the distance of Neptune from the Sun.
The planet was first seen in 2004, but astronomers had to wait a year to confirm it really was a planet and not a background star or galaxy. Over time, as the star moved slightly in our sky, the planet moved with it
, confirming they were a pair.
This picture is indeed historic, but left many people unsatisfied. Brown dwarfs are bigger than planets, but not really stars, either. And while 2M1207 b was definitely a planet, everybody was hoping to find a planet around a bona-fide star like the Sun.
