The first-ever ringed planet beyond our solar system has been found by astronomers. Named as J1407b, has a disk of 30-odd rings which is so vast that, had it been around Saturn, it would have dominated our night sky.
Matthew Kenworthy of the Leiden Observatory in The Netherlands said, ?It?d be huge! You?d see the rings and the gaps in the rings quite easily from Earth.?
Kenworthy and Eric Mamajec of New York?s University of Rochester search through a database of millions of stars photographed by telescopes around the world in an exoplanet search project called SuperWASP.
Exoplanets, worlds beyond our own Solar System, are observed from Earth through changes in the brightness of their central star. Kenworthy said the planet itself was probably about 10 to 40 times the mass of Jupiter, the biggest planet of our star system.
The planet?s rings begin at a distance of about 30 million kilometres from the planet and stretch out to a distance of 90 million kilometres and they are probably made of dust, as planet J1407b is too hot to support ice rings like those orbiting Saturn.

The Cassini imaging team have released a set of never-before-seen images and movies of the Saturn system to coincide with the opening of a week-long celebration of the mission at the Royal Observatory, Greenwich. Cassini has been orbiting Saturn since...
- Saturn's Approach To Equinox Reveals New Detail In Rings
Towering vertical structures in Saturn?s rings have been discerned for the first time by Cassini as the giant planet approaches equinox. Equinox defines the exact moment when the Sun is seen directly overhead at noon at a planet?s equator, and occurs...
- Rocky Earthlike Planet Discovered
Researchers on 21.4.09 confirmed the existence of a rocky Earthlike planet with a mass of 1.9 Earth masses, orbiting in the Gliese 581 system. Another planet in the four planet system was also found to be lying in the star's habitable zone, the...
- Equinox On Saturn
About every 15 Earth years, Saturn?s experiences an equinox, much like Earth?s equinox. On Earth it occurs twice in Earth?s orbit?two times every Earth year?when the Sun lies in the Earth?s equatorial plane. As a result, the duration of day and night...
