Star clusters are not only beautiful to look at through telescopes, but they're also the key to unlocking the mysteries of how a star is born.

Astronomers have found clues to a large planet orbiting three stars.

It's like a Tatooine supreme.

Researchers in the UK have devised a process that uses electricity to remove radioactive contaminants from irradiated nuclear graphite. The process could reduce the volume of waste from nuclear power plants that requires expensive and long-term storage.

Researchers from the Ê×Ò³| Â鶹´«Ã½Ó³»­ (UNLV) in the United States said they had discovered an exoplanet orbiting three suns, also known as the 3rd Binary Star (Trinari).

In a distant star system — a mere 1,300 light-years away from Earth — researchers may have identified the first known planet to orbit three stars. The potential discovery of a circumtriple planet has implications for bolstering understanding of planet formation.

Although our solar system has only one star in the center, half of the systems contain two or even more stars that orbit each other by gravity. But so far, no one has seen a planet orbiting the three stars.

Planets orbit stars. Everyone knows that, but have you ever heard of a planet that orbits not two stars, but three?

In 1949 a team of astronomers discovered a star 1,300 light-years from Earth, at the head of Orion the Hunter. Since then, astronomers have found that the star—GW Orionis—has two stellar companions.

"Star Wars" showed us a planet with two suns in the sky. Now a UNLV researcher and an international team are doing better: They may have identified the first planet to orbit three stars.

Our Solar System, with just one star in the sky, may be a bit of an oddball. Most of the stars in the Milky Way galaxy actually have at least one gravitationally bound stellar companion, meaning that two-starred worlds like Tatooine are probably not uncommon.

Two's company, three's a crowd?
