Bad Astronomy | Fast radio bursts traced to galaxies' spiral arms

La NASA rastrea ubicación de misteriosas ráfagas rápidas de radio

Some fast radio bursts come from the spiral arms of other galaxies

Tracking five brief, bright blasts of cosmic radio waves to their origins suggests their sources form quickly in regions with lots of star formation.

Hubble Tracks Down Location of Mysterious Fast Radio Bursts From Intergalactic Space

While astronomers are anxiously awaiting the deployment of the joint NASA–ESA–CSA James Webb Space Telescope – with its state-of-the-art infrared resolution and sensitivity – the Hubble telescope is not going down with a whimper. In a telescopic “Hold my beer and watch this” moment, NASA announced that astronomers using the Hubble Space Telescope tracked five of those mysterious fast radio bursts (FRBs) to the spiral arms of five distant galaxies, helped rule out some probable causes and may have proved where they actually come from. You go, Hubble! “A galaxy’s spiral arms trace the distribution of young, massive stars. However, the Hubble images reveal that the FRBs found near the spiral arms do not come from the very brightest regions, which blaze with the light from hefty stars. The images help support a picture that the FRBs likely do not originate from the youngest, most massive stars.”
