In 13 stars, most of which were like our sun, the researchers saw dips in these emissions lasting up to 10 hours, with 21 such events spotted. They argue that these dips are the result of coronal mass ejections throwing material from the star into space, reducing the mass of the ...
NASA scientists reported Nov 4, 2014, on the summary of results from the third year of the Kepler Space Telescope observations. Based on the results from measurements on 40,000 Sun-like stars, Erik Petigura, PhD student at the University of California, Berkeley, Calif. reported that about ...

For the first time, astronomers have found alien planets orbiting sun-like stars in a crowded star cluster, researchers announced today (Sept. 14).
Seeking these more elusive binaries, El-Badry’s team scoured data from the ESA’s Gaia space observatory, which measures the positions, distances, and motions of stars with high precision.The astronomers looked for Sun-like stars that “wobbled” in the sky as they orbited invisible ...

1 There are many stars in space. The Sun is a star. It gives us heat and light. Planets do not give out light like stars. Some planets are balls of rock and some are balls of gas. We live on the planet Earth. The Earth spins round once every day to give us day and night....
"Sothe smallest one is in the super-Earth mass range, and is the first planet likethis to be found around a sun-like star," Tinney told SPACE.com. Othersuper-Earths have been found aroundstars that are cooler and redder than the sun, he said. Tinneyadded, "This is exciting, because...
Earth and other planets in the solar system formed from material left over after the formation of the sun. Therefore, studying young, sun-like stars like IRAS 16293-2422 can help astronomers learn more the early years of our solar system. Get the Space.com Newsletter Breaking space news, the...
