    Deep Learning Speeds up Galactic Calculations

    November 1, 2023, Categories  Astronomy/Space, Physics

    Four square images showing dark backgrounds with stars and galaxies
    Divide and conquer. The upper images show a wide area of a galaxy being simulated. The time resolution is very low, in which each “step” of the simulation is around 100,000 years. The lower images show the specific area affected by a supernova explosion and have a finer time resolution where each step is under 10,000 years. These regions are combined with the more general simulation to improve the overall accuracy and efficiency of the simulation. ©2023 Hirashima et al., NASA/JPL-Caltech/ESO/R. Hunt/Hubble/L.

    A new way to simulate supernovae may help shed light on our cosmic origins. Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies...

    Astrophysics: A direct view of Star/Disk Interactions

    September 1, 2020, Categories  Astronomy/Space

    Artist’s impression of the streams of hot gas that build up stars. Matter from the surrounding protoplanetary disk, the birthplace of planets, is channeled onto the stellar surface by magnetic fields shocking the surface at supersonic velocity (Copyright: Mark A. Garlick).

    A team including researchers from the Institute for Astrophysics of the University of Cologne has for the first time directly observed the columns of matter that build up newborn stars. This was observed in the young star TW Hydrae system located approximately 163 light years from Earth. This result was obtained with the Very Large Telescope Interferometer (VLTI) and its GRAVITY instrument of the European Southern Observatory (ESO) in Chile...

    A cluster of small and low-cost nanosatellites is ready for liftoff from Hawaii – an inventive effort called the Edison Demonstration of Smallsat Networks (EDSN) mission for scientific, commercial, and academic research tasks in space.

    The flock of 8 tissue box-sized satellites is set to ride into Earth orbit as secondary payloads on the U.S. Department of Defense Operationally Responsive Space-4 mission.
