Nearest Exoplanet Discovered in the Alpha Centauri System
Astronomers from the European Southern Observatory have discovered the nearest extrasolar planet to date, in the Alpha Centauri star system 4.3 light years away. The system is composed of three stars -- two stars similar in size to our Sun orbiting close to each other and…
Monthly Stargazing Calendar for September 2012
By the end of the month on September 29, Uranus will be at opposition. The gas giant will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This makes it the best time to view Uranus. Due to its distance, it will only appear as a tiny blue-green dot in all but the most powerful telescopes.

Antennae Galaxies – Astronomy Picture of the Week
This beautiful image of two colliding galaxies has been released by NASA's great observatories. The Antennae galaxies are located about 62 million light-years from Earth. They take their name from the long antenna-like "arms," which were produced by tidal forces generated in the collision.

Tatooine-Like Planet Discovered Orbiting Two Suns
An exoplanet that orbits around two stars, known as a circumbinary planet, has recently been discovered by astronomers using the Kepler space telescope. The planet dubbed Kepler-16b has been compared to the planet Tatooine from Star Wars, due to the fact that it has two Suns in its sky.
