Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.
The data was gathered from the deepest-ever survey of NGC1333, a star-forming cluster located about 1,000 light-years from Earth. The newly discovered planets are among the lightest ever detected and ...
IT’S been nearly 40 years since the first planet outside of our Solar System was discovered. Since then, more than 5,800 weird and wonderful worlds across 4,300 planetary systems have been ...
Astronomers have revealed new evidence that not just one, but four tiny planets are circling around Barnard's Star, the ...
Planet demographics reveal a puzzling lack of worlds in a certain size range throughout the galaxy F or centuries our solar ...
Whenever planets are visible in the night sky, they always appear roughly along the same line. This path, known as the ...
UCLA astrophysicists have now measured the shape of the orbits of exoplanets — from the size of Jupiter down to the size of Mars — and shown that small planets have nearly circular orbits ...
The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star.
Scientists are discovering more exoplanets, but they’re still figuring out how these planets form. Jupiter-like exoplanets ...
NASA’s Juno spacecraft identifies over 40 enormous lava lakes on Io, shedding light on the extreme volcanism sculpting Jupiter’s moon.
