The nearest stars, their distances in light-years, spectral types and known planets. Only 9 of the stars within 15 light years can be seen with the unaided eye from Earth.

Astronomers have discovered an Earth-size planet orbiting one of the nearest stars in our galaxy.

This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach.

Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Neptune was the first planet found by mathematical prediction rather than by empirical observation.

Take 165 years for Neptune to travel around the Sun. So generation of persons born Scorpio in Neptune. Next sign to go into Neptune is Sagittarius. In 2011 Neptune completed its orbit of the Sun since it discovery in It has 13 moons and 6 rings.

In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole"
