The world known officially as PSR B1620-26 b orbits a binary star system about 12,000 light-years away. With an estimated age of 12.7 billion years, PSR B1620-26 b is considered one of the oldest planets in the universe, more than twice as old as our solar system. Astronomers found it in the 1990s because of the tug it exerts on its two stars, a pulsar and a white dwarf.

Earlier today, NASA announced the Hubble Space Telescope has discovered a brand new moon in the solar system, a dim satellite only 12 miles across, orbiting Neptune. As with any newborn, it needs a name. How will astronomers decide what to call it?

Remember last week when PopSci told you about a "people's choice" contest to name the planet orbiting the Alpha Centauri star system? And the International Astronomical Union had cried foul, saying the paid contest had no bearing on the names? Well, it's not really that simple. You can call a star or a planet whatever you want, and even pay to nominate your favorite; it just might not matter to anyone else.

Most of the more than 800 exoplanets discovered have unbelievably boring names - 16 Cygni Bb or HD 41004 Ab, to name a couple. So some enterprising entrepreneurs have started a naming contest that allows users to pay to nominate and vote on new names ($4.99 a pop, though there are obviously bulk prices available as we've got a lot of planets to name). Namers receive a certificate commemorating their contribution to the wonderful world of science. Totally not sketchy at all, right?

The asteroid Vesta was first discovered two centuries ago, but until NASA's Dawn spacecraft arrived there earlier this year and began beaming back images and data, Vesta was seen as just another blurry, rocky satellite out there orbiting in the asteroid belt. Now, with Dawn's instruments giving researchers their first really good look at Vesta's composition and surface features, some astronomers are wondering if perhaps they haven't discovered a small terrestrial planet rather than an asteroid.
