    ‘Ears’ for Rover Perseverance’s Exploration of Mars

    April 6, 2022, Categories  Astronomy/Space

Gill/Italian Space Agency/Italian National Institute for Astrophysics/Björn Jónsson/ULiège/Bertrand Bonfond/Vincent Hue NASA’s Juno spacecraft flew through the intense beam of electrons traveling from Ganymede, Jupiter’s largest moon, to its auroral footprint on the gas giant. SwRI scientists used the resulting data to connect the particle population traveling along the beam with associated auroral emissions to unveil the mysterious processes creating the shimmering lights.

    Hubble finds a Protoplanet that could Upend Planet Formation Models

    April 6, 2022, Categories  Astronomy/Space

    Researchers were able to directly image newly forming exoplanet AB Aurigae b over a 13-year span using Hubble’s Space Telescope Imaging Spectrograph (STIS) and its Near Infrared Camera and Multi-Object Spectrograph (NICMOS). In the top right, Hubble’s NICMOS image captured in 2007 shows AB Aurigae b in a due south position compared to its host star, which is covered by the instrument’s coronagraph. The image captured in 2021 by STIS shows the protoplanet has moved in a counterclockwise motion over time.

    The presence of unusually energetic gamma rays seen in some afterglows from intense gamma-ray bursts (GRBs) could be explained by a new mathematical model developed by RIKEN researchers. This finding could help to shed light on the origin of GRBs.

    A GRB is a spectacular eruption of energy produced by violent events such as the explosive death of a massive star, or the collision of two neutron stars...

    Impact of Black Hole Winds, Radiation examined in new study

    April 1, 2022, Categories  Astronomy/Space

    Black holes are regions of space where gravity is so strong that nothing can escape. New research is examining the radiation and winds emanating from black hole activity and shows how they may exert effects on nearby planets.

    “The impact of AGN outflows on the surface habitability of terrestrial planets in the Milky Way” is a research paper by the team of astrobiologist Manasvi Lingam and astrophysicist Eric Perlman from Florida Tech’s Department of Aerospace, Physics and Space Sciences, as well as researchers from the University of Rome, University of Maryland and Goddard Space Flight Center...
