¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2020 September 29 IFRAME: [2]https://www.youtube.com/embed/ictZttw3c98?rel=0 GW Orionis: A Star System with Titled Rings Animation Illustration Credit: [3]ESO, [4]U. Exeter, [5]S. Kraus [6]et al., [7]L. Calçada Explanation: Triple star system GW Orionis appears to demonstrate that planets can form and orbit in multiple planes. In contrast, all the planets and moons in [8]our Solar System orbit in nearly the [9]same plane. The [10]picturesque system has three prominent stars, a warped disk, and inner tilted rings of gas and grit. The [11]featured animation characterizes the [12]GW Ori system from observations with the [13]European Southern Observatory's [14]VLT and [15]ALMA telescopes in [16]Chile. The [17]first part of the illustrative video shows a grand vista of the entire system from a distant orbit, while the [18]second sequence takes you inside the [19]tilted rings to resolve the three central [20]co-orbiting stars. Computer [21]simulations indicate that multiple stars in systems like GW Ori could [22]warp and break-up disks into unaligned, [23]exoplanet-forming rings.
