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't quite sure how many planets are in the Milky Way, given we have only found a ...
The Milky Way is the galaxy that contains our Solar System.[1][2][3][nb 1] This name derives from its appearance as a dim "milky" glowing band arching across the night sky, in which the naked eye cannot distinguish individual stars. The term "Milky Way" is a translation of the Clas...
哈勃望远镜的红外视觉系统穿透银河系(Milky Way galaxy)积满尘埃的“心脏”,揭示了银河系的核心拥有超过50万的恒星。在银河系的正中央,这一星团盘旋在银河系中央的超大质量黑洞周围,该黑洞的质量是太阳的400万倍。 图片来源:(NASA), 欧洲航天局(ESA),及哈勃遗产团队(太空望远镜科学研究所(STScI)/大学天文研究协会...
This enormous section of the Milky Way galaxy is a mosaic of images from NASA’s Wide-field Infrared Survey Explorer, or WISE. The constellations Cassiopeia and Cepheus are featured in this 1,000-square-degree expanse. These constellations, named after an ancient Queen and King of Ethiopia in ...

Despite decades of large-scale optical surveys, there are still mysteries about the Milky Way galaxy that astronomers are eager to resolve. This is particularly true of its internal structure and the core region, which is difficult to survey due to clouds of gas and dust in the interstellar me...
Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.
The article offers information on the Milky Way galaxy and the identification of the trigger for the it's youngest supernova discovered by the U.S. National Aeronautics and Space Administration's (NASA) Chandra X-ray Observatory and U.S. National Science Foundation's (NSF) Jansky Very Large ...

Scientists now estimate that there are as many as 50 billion planets in our own Milky Way galaxy, reports theAP. More interesting, 500 million of them may be in zones where life could exist. These numbers come, of course, from NASA’s Kepler telescope, which was launched specifically for ...
