new planet
Astronomers have also discovered more than 200 planets orbiting other stars. [1]
Technological advances, most notably in high-resolution spectroscopy, led to the detection of many new exoplanets at a rapid rate. [2]
“Like our own giant planets, Jupiter and Saturn, the planet is mostly made of hydrogen and helium,” said team member Tristan Guillot of the C?te d’Azure Observatory in Nice, France. [3]
Stars orbited by planets are a little bit different than other stars, and scientists can use that to quickly home in on new planets. [4]
It is unclear whether the companions should be regarded as planets or brown dwarfs. [2]
Astronomers have recently found hundreds of new planets. [4]
For many astronomers the Kuiper Belt has become an exciting spot for innovative research and has changed how they view the solar system. [5]
We are only beginning to discover how vast and strange our solar system truly is. [4]
… some astronomers distinguish stars from planets not by mass by how they formed. [1]
In the sixteenth century the Italian philosopher Giordano Bruno, an early supporter of the Copernican theory that the Earth and other planets orbit the Sun, put forward the view that the fixed stars are similar to the Sun and are likewise accompanied by their own planets. [2]
The batch of freshly discovered worlds include four that are only five or six times the mass of Earth, an encouraging sign in the quest for a truly Earth-like world that could support life. [...] Astronomers have announced the discovery of 32 new planets orbiting distant stars, bringing the list of known exoplanets up to more than 400. [3]
Since astronomers cannot go back in time to see exactly how something formed, Gibor Basri, a professor of astronomy at the University of California, Berkeley, invented the word, “planemo,” a shortening of “planetary mass object” (and pronounced PLAN-uh-moh), to describe any object with a mass less than 13 Jupiter masses regardless of how it formed. [1]
Meet Corot-9b, the newest find in the cavalcade of exoplanets and the one its discoverers say is most like the worlds of our own solar system. [...] In a star system 330 light years away from Earth, astronomers have spotted a giant planet that booms around its parent star in tight, fast circles, completing an orbit (the planet’s “year”) in less than one Earth day.
