Stellar populations in the Milky Way bulge region: towards solving the Galactic bulge and bar shapes using 2MASS data We re-analyse photometric near-infrared data in order to investigate why it is so hard to get a consensus for the shape and density law of the bulge, as se... AC Robin...

More recently, astronomers have been trying to figure out what type of galaxy the Milky Way is. Our best estimates these days suggest that it is a barred spiral, meaning that there is a bar structure across the center. Astronomers can estimate the shape of the Milky Way by looking at its...
By determining the 3D coordinates of each distant pulsing star relative to the sun, the researchers built a large-scale 3D model of the Milky Way galaxy. The previous understanding of the spiral shape and structure of the Milky Way is built upon indirect measurements to celestial landmarks and...

This issue’s chapter is a flashback to Shanghai in the mid-1930s, as the Green Gang (a real organisation) stabs and beheads its way to the control of the local drug trade. I was in Shanghaionly recently, and impressed not only by the photo-real accuracy of Shikako’s depiction of...
【题目】The Milky Way Galaxy is twisted in shape银河系是弯的Astronomers have created the most precise map to date of the Milky Way-by tracking thousands of big pulsatingstars spread throughout the galaxy, demonstrating that its disk of myriad(无数的) stars is not flat but dramaticallywarped ...
A satellite galaxy is a clump of stars, either in a circular blob or a halo-like shape, that orbit the Milky Way independently from the rest of the galaxy. Our galaxy's largest-known satellite is the Large Magellanic Cloud, which holds around 30 billion stars and ca...
A few days ago Milky Way Project user suelaine posted an image of this pretty bubble on the Talk forum, asking whether it was a supernova. As supernovae – or rather, the debris that’s left behind after they explode – often have this kind of shape, I initially thought she was righ...
