[21][22] Earth-sized planets may be more numerous than gas giants.[7] The disk of stars in the Milky Way does not have a sharp edge beyond which there are no stars. Rather, the concentration of stars drops smoothly with distance from the center of the Galaxy. Beyond a radius of ...
Where is Earth in the Milky Way? Earth is located roughly halfway to the edge of the Milky Way, at a distance of about 26,000 light years from the center. We reside in a feature known as the Orion Spur (sometimes also called the Orion Arm), which is an offshoot between the larger ...
The Milky Way is the galaxy that contains the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The Milky Way is a barred spiral galaxy with a...

Milky Way Galaxy - Structure, Dynamics, Stars: The first reliable measurement of the size of the Galaxy was made in 1917 by American astronomer Harlow Shapley. He arrived at his size determination by establishing the spatial distribution of globular clus

(Image credit: NASA/JPL-Caltech) Far-off alien planets covered in vast oceans might be common in our Milky Way galaxy, scientists find. "Ocean worlds" are terrestrial planets that have significant amounts of water either on their surfaces or in a subsurface sea. Right here in our own ...
3The Milky Way is full of habitable(宜居)places, with roughly half of all sunlike stars hosting Earth-size worlds that could be friendly to life. Here's a good sign for alien hunters:More than 300 million worlds with similar conditions to Earth are spread throughout the Milky Way galaxy....
NASA has released a guide to the night sky this July pointing out that it is one of the best times of year to capture the Milky Way Galaxy.
