Hubble's precursor imaging of the Milky Way's galactic bulge will calibrate and guide NASA's Nancy Grace Roman Space Telescope’s upcoming Galactic Bulge Time-Domain Survey, enabling precise mass measurements and a census of microlensing events, rogue planets, and compact objects, with six 72‑day seasons and high-cadence observations ahead of Roman's 2026 launch.
Scientists have discovered a mysterious alignment of planetary nebulas in the galactic bulge at the center of the Milky Way. These clouds of gas, expelled by dying stars, are arranged in a parallel line almost perpendicular to the plane of the galaxy. The alignment is only present in planetary nebulas with a close stellar companion, suggesting that the rapid orbital motion of the companion star creates the alignment. This finding provides insight into the dynamics and evolution of the Milky Way's bulge region and the formation of close binary systems.
Scientists have discovered that the alignment of planetary nebulas in the galactic bulge at the center of the Milky Way is only present in nebulas with a close stellar companion. This suggests that the alignment is created by the rapid orbital motion of the companion star, which may even end up orbiting inside the remains of the main star. The findings deepen our understanding of the dynamics and evolution of the Milky Way's bulge region and provide insights into the formation of close binary systems.
Scientists have discovered the reason behind the mysterious alignment of planetary nebulas in the galactic bulge at the center of the Milky Way. Using images from the Hubble Space Telescope, researchers found that the alignment is only present in planetary nebulas with a close stellar companion. The alignment is absent in planetary nebulas without a companion star, suggesting that the rapid orbital motion of the companion star creates the alignment. This finding provides insight into the complex process of star formation in the Milky Way's bulge region.
