Lee Rannals for redOrbit.com - Your Universe Online Astronomers wrote in the journal Astronomy & Astrophysics that one of the closest and most Sun-like stars may actually host five planets. The star, which lies 12 light-years away and is visible to the naked eye, is the closest single star that has the same spectral classification as our Sun. Tau Ceti has five planets that are estimated to have masses between two and six times the mass of the Earth, making it the lowest-mass...

Brett Smith for redOrbit.com - Your Universe Online Using a radio telescope in the mountainous area of southern Spain back in 1995, astronomer Benjamin Zuckerman and two colleagues found an unusually high amount of carbon monoxide gas orbiting a star in the constellation Cetus, 49 CETI. "We now believe that 49 CETI is 40 million years old, and the mystery is how in the world can there be this much gas around an otherwise ordinary star that is this old," said Zuckerman, currently a UCLA...

For 50 years now, astronomers and space enthusiasts have been listening for signals in the background noise of space that might point to another civilization, but some experts say numerous messages zipping through the cosmos could be confusing or simply meaningless, AFP reported. NASA beamed the Beatles song "Across the Universe" into deep space in 2008, sending a message of peace to any extraterrestrial who happens to be in the region of Polaris, also called the North Star, in 2439. Former...

AAAS -- In the search for life on other worlds, scientists can listen for radio transmissions from stellar neighborhoods where intelligent civilizations might lurk or they can try to actually spot planets like our own in habitable zones around nearby stars. Either approach is tricky and relies on choosing the right targets for scrutiny out of the many thousands of nearby stars in our galactic neighborhood. Margaret Turnbull, an astronomer at the Carnegie Institution of Washington, has...

Tau Ceti -- Tau Ceti is a star commonly used by science fiction authors since it is similar to the Sun, being of similar mass and similar spectral type as well as being relatively close to us. However, Tau Ceti is a "metal-deficient" star and therefore extremely unlikely to have rocky planets around it. It can be seen with the unaided eye as a faint star in the constellation of Cetus. ----- Click here to learn more on this topic from eLibrary:

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...
