The new study by CfA researchers and colleagues leverages two major datasets gathered in recent years that have plumbed the stellar halo as never before. The goal has since been to study the patterns of over-densities of stars-spatially appearing as bunches and streams-to sort out the ultimate origins of the stellar halo. Through such studies, astronomers have realized that halo stars are not evenly distributed. Yet over time, astronomers have succeeded in identifying many thousands of stars that populate this halo, which are distinguishable from other Milky Way stars due to their distinctive chemical makeup (gaugeable by studies of their starlight), as well as by their distances and motions across the sky. "Unlike with external galaxies, where we just look at them and measure their halos," says Han, "we lack the same sort of aerial, outside perspective of our own galaxy's halo."Ĭomplicating matters further, the stellar halo has proven to be quite diffuse, containing only about one percent of the mass of all the galaxy's stars. The stellar halo extends out several hundred thousand light years above and below the star-filled plane of our galaxy, where our Solar System resides. "In order to learn more about galactic haloes in general, and especially our own galaxy's galactic halo and history, the stellar halo is a great place to start."įathoming the shape of the Milky Way's stellar halo, though, has long challenged astrophysicists for the simple reason that we are embedded within it. "The stellar halo is a dynamic tracer of the galactic halo," says Han. To better understand how galaxies form and interact, as well as the underlying nature of dark matter, stellar haloes are accordingly valuable astrophysical targets. In turn, that visible matter forms stars and other observable galactic structure. These halos serve as a sort of scaffold upon which ordinary, visible matter hangs. Every galaxy has its own halo of dark matter. This galactic halo is dominated by invisible dark matter, whose presence is only measurable through the gravity that it exerts. The Milky Way's stellar halo is the visible portion of what is more broadly called the galactic halo.

"We now know that the textbook picture of our galaxy embedded within a spherical volume of stars has to be thrown out."Īstronomers have discovered that the Milky Way galaxy's stellar halo-a cloud of diffuse stars around all galaxies-is zeppelin-shaped and tilted. "For decades, the general assumption has been that the stellar halo is more or less spherical and isotropic, or the same in every direction," adds study co-author Charlie Conroy, Han's advisor, and a professor of astronomy at Harvard University and the Center for Astrophysics. "There are a lot of important implications of the stellar halo not being spherical but instead shaped like a football, rugby ball, or zeppelin-take your pick!" ![]() student at the Center for Astrophysics | Harvard & Smithsonian. "The shape of the stellar halo is a very fundamental parameter that we've just measured to greater accuracy than was possible before," says study lead author Jiwon "Jesse" Han, a Ph.D. The results, for example, shed light on the history of our galaxy and galactic evolution, while also offering clues in the ongoing hunt for the mysterious substance known as dark matter. Click the link above if you feel like looking at your own service record.The findings-published this month The Astronomical Journal - offer insights into a host of astrophysical subject areas. Obviously we can't officially recommend a site we don't know all the details of yet, but a few experiments made it seem both helpful and harmless enough. By entering your Xbox Live username, the site pulls all manner of stats, including kills, deaths, win ratio, accuracy, even smaller details like melee kills, vehicle hijacks and - oops - betrayals. This is a website not officially associated with 343 or Microsoft in any way, but nonetheless it did seem to provide details on our military history in Halo Infinite. Specifically, the site that helped us was one named HaloTracker. Historically these have been documented on the tie-in app/website Halo Waypoint, but as of yet this doesn't seem to be the case, likely added later. The game has no equivalent of the Barracks, Records or kill/death/assist tracker right now, meaning that those who want to know how they're doing in the eternal war of Spartan v. The Halo Infinite K/D tracker and long-term player records, any details about the overall skill exhibited in Infinite's multiplayer… well, you can't find it. ![]()
