Scientists are using an array of instruments to detect other planets, some of which may harbor life—and others that most ...

The team found that larger planets on non-circular orbits are more likely to have grown in more turbulent home systems. To reach this conclusion, the team studied the orbits of thousands of ...
A combination of the world's most powerful telescopes detected the planets. Astronomers have confirmed the existence of four planets orbiting a star less than 6 light-years away with help from ...
The four planets are classified as sub-Earths because each one is about 19% to 34% the mass of Earth, according to new research. “It’s a really exciting find — Barnard’s Star is our cosmic ...
our sun's closest planet, Mercury, orbits in 88 days). It is likely they all have masses less than Earth's. They're probably rocky planets, with bare-rock surfaces blasted by their star's radiation.
and are in orbits with periods that range from decades to centuries. This system has long intrigued astronomers studying planet formation, largely because of its youth — at just 30 million years ...
The angle from Earth means these planets do not appear to pass in front of their star, so the usual tests to identify rock or gas are out of reach. However, these orbits are probably far too close to ...
The answer lies in the effect of their gravity on the star. The mutual gravitational attraction keeps the planets in their orbits, but also tugs on the star, moving it in a rhythmic dance that can ...
