我们最熟悉的星系也许就是我们所在的银河系了,其英文便是我们在标题中提到的the Milky Way,在晴朗的夜空中很容易观测到。英文中Galaxy首字母大写的时候也可以专指银河系。 左图:夜空中看到的银河 图源:Wikipedia 右图:科学家绘制的银河系图 图源:nasa.gov 为什么银河...

NASA has released a guide to the night sky this July pointing out which celestial objects will be prominent and highlighting that it is one of the best times of year to capture the Milky Way Galaxy. Summertime in the northern hemisphere is a good time to go outside at night with your ...
"Using the precise locations of very young objects, for the first time, we propose that our galaxy has a multiple-arm morphology that consists of two-arm symmetry," they wrote. "The Norma and Perseus Arms are likely the two symmetric arms in the inner Milky Way. As they extend from the...

(NASA / NASA) To help narrow down when you can look up and see the Milky Way in full detail, consider when the sky is as dark as possible, specifically regarding the Moon and bright moonlight. The darkest skies are seen during the New Moon, when the night side of the Moo...
To get a sense of its immense size, you’ll be glad to hear the Earth is nowhere near the Milky Way’s center and its powerful, supermassive black hole.NASAsays we’re roughly 165 quadrillion miles from the black hole, which is found in the direction of the constellation Sagittarius. ...
As you look towards Sagittarius A*, the assumed black hole in the dense middle of our galaxy, there is simply muchmore cosmic material; more stars, gas, and dust, for light to reflect on than in the further reaches of the Milky Way. So, if the conditions are right, this tightly-packe...
Peering deep into the heart of our home galaxy, the Milky Way, the NASA/ESA Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Apart from a few, blue, foreground stars, almost all of the stars pictured in the image are members of the Milky Way nuclear st...
the Milky Way galaxy from NASA’s Wide-field Infrared Survey Explorer, or WISE, shows dozens of dense clouds, called nebulae. Many nebulae seen here are places where new stars are forming, creating bubble-like structures that can be dozens to hundreds of light-years in size. Credit: NASA ...
