The mass of the Milky Way, dark matter included, equals 1.5 trillion solar masses, according torecent NASA estimates. The galaxy's visible matter is distributed between its 200 billionstars, their planets and the massive clouds of dust and gas that fill the interstellar space. Astronomers aren'...
The calculation required help from the European Space Agency's Gaia spacecraft,which monitors stars across the galaxy. With Gaia's observations in hand,scientists were finally able to determine that the Milky Way is populated by hundreds of millions of Earth-size planets orbiting sunlike stars-and...
HOUSTON, Feb. 2 (Xinhua) -- A University of Oklahoma astrophysics team has discovered a population of planets beyond the Milky Way galaxy. Using microlensing -- an astronomical phenomenon and the only known method capable of discovering planets at great distances from the Earth -- the researcher...

like spilled milk. Astronomers estimate that there are between 100 and 400 billion stars in the Milky Way, and think that each star has at least one planet. So there are likely hundreds of billions of planets in the Milky Way, and at least 17 billion of those are the size and mass of...
So Many ’Earths’ The Milky Way (银河)contains billions of Earth-sized planets that could support life that’s the finding of a new study. It draws on date that came from NASA’s top planet-hunting telescope. A mechanical failure recently put that Kepler space telescope out of service. ...

The Milky Way is only one galaxy among a few hundred million galaxies in our universe (each with hundreds of billions of stars). Galaxies are huge groupings of stars, planets, gas and dust. Our sun is in the Milky Way, which measures about 100,000 light years across. That long thin ...
