A massive dying star located approximately 500 million light-years from Earth has provided astronomers with an unprecedented close-up view of a supernova explosion, according to research published in the Astrophysical Journal Letters. According to Brendan O’Connor, a postdoctoral researcher at Carnegie Mellon University in Pittsburgh and lead author of one of the studies, observing these cosmic events in real time requires precise fortune.
Catching a Supernova Wave in Real Time
When massive stars collapse, they generate shockwaves that act much like a radar system. According to Jillian Rastinejad, an Einstein fellow at the University of Maryland and lead author of the second study, these shockwaves sweep through the outer layers of the star and nearby material, leaving distinct signatures in X-ray emissions.
Researchers quickly mobilized a network of instruments following the detection. According to study data, the observation campaign utilized the orbiting Chandra X-ray Observatory alongside various ground-based facilities to track the event continuously for nearly three months, until the supernova’s position shifted behind the sun from Earth’s perspective.
Massive Star Metrics and Comparisons
Astronomers estimate that the collapsed star possessed roughly 30 times the mass of our sun prior to its explosion. This places the progenitor among the most massive stellar objects studied, likely exceeding the size of Betelgeuse, one of the brightest stars in the night sky and a well-known red supergiant situated in the Milky Way between 500 and 600 light-years away, as noted by Rastinejad.
Did you know? One light-year represents the distance light travels in a single Earth year, equating to approximately 9,5 trilhões de quilômetros.
