A recent study of the supernova SN 2024bch challenges traditional models by suggesting Bowen fluorescence, rather than debris interaction, explains its energy output, potentially altering our understanding of Type II supernovae and their role in neutrino production and multimessenger astronomy.
The Hubble Space Telescope has captured an image of the aftermath of a Type II supernova, SN 2010jl, in the small galaxy UGC 5189A, located 150 million light-years away. This exceptionally luminous supernova released at least 2.5 billion times more visible energy than the Sun over a three-year period. The remnant has been studied to understand supernova triggers and their impact on the surrounding environment, with observations suggesting that the supernova explosion itself may have created dust.
Gemini North, part of the International Gemini Observatory, has returned to observing the night sky following the repair and refurbishment of its primary mirror. Its debut observation captured the closest supernova seen in the past five years, SN 2023ixf, located in the Pinwheel Galaxy. The telescope's exceptional spectroscopic capabilities will allow astronomers to study how the light from the supernova fades and how its spectrum evolves over time, helping them better understand the physics of such explosions. The successful repair of the mirror is a great team effort for NOIRLab and its contractors at Safran-Reosc.
The Pinwheel Galaxy, also known as M101, has a visible Type II supernova named SN 2023ixf, which can be seen with a small telescope. This supernova is expected to brighten a bit more over the next couple of months before gradually fading. The observations of this supernova will help astronomers better understand the evolution of core-collapse supernovae and how they enrich the universe with heavy elements.
The Hubble Space Telescope captured an image of the spiral galaxy NGC 298, which was previously the site of a Type II supernova, as part of an investigation into the origins of these star explosions. The study aims to explain the diversity in Type II supernovae by observing the regions around these events, potentially revealing information about the stars’ history and surviving companion stars. Hubble hopes to piece together the relationship between Type II supernovae and the stellar systems which give rise to them.
The Hubble Space Telescope captured an image of the aftermath of a Type II supernova explosion in the spiral galaxy UGC 2890, which is located 30 million light-years away in the Camelopardalis constellation. Hubble's investigation of Type II supernovae helps to reveal insights into the types of stars that create these explosions and any survivors of these catastrophic events. This observation is one of many Hubble investigations of Type II supernovae, revealing any stellar survivors of colossal supernova explosions.
