Being embedded in the Milky Way is actually a major obstacle to our galactic cartography, however. We see every other galaxy from the outside, allowing us to observe most of them sprawled out before us. That makes mapping their structure relatively easy. 然而,正因为我们位于银河系内部,反而给...

Despite having surveyed this colossal structure for centuries, we are also still learning new things about our incredible galaxy, such as how it recycles stellar material and where it fits into the wider universe. So how well do you know the Milky Way? Let's test your knowledge of our galax...
The Milky Way is warped, possibly as the result of a collision with another galaxy billions of years ago. Studying this warp could reveal more about the structure of our galaxy's hidden matter.When you purchase through links on our site, we may earn an affiliate commission. Here’s how it...
Max Planck Institute of Astronomy (MPIA) recently noticed a massive filament of atomic hydrogen gas in our galaxy. This structure, named Maggie, is located about 55,000 light-years away (on the other side of the Milky Way) and is one of the longest structures ever observed in our galaxy....
This map shows the full extent of the Milky Way galaxy - a spiral galaxy of at least two hundred billion stars. Our Sun is buried deep within the Orion Arm about 26 000 light years from the centre. Towards the centre of the Galaxy the stars are packed together much closer than they ar...
Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common ...
