Astronomers are detecting unprecedented cosmic explosions that challenge existing models of how stars die and energy releases. Recent observations include the earliest millimeter-wave views of these events, mysterious blasts with no clear explanation, and evidence that ancient explosions continue raining radioactive material on Earth today.
·SMA telescope captured the earliest millimeter-wave observations of a cosmic explosion, revealing new details about how these events unfold
·A record-breaking gamma-ray burst is forcing scientists to reconsider their understanding of explosion mechanisms and energy output
·Einstein Probe detected a mysterious cosmic explosion with no identified cause, challenging classification systems
·Plutonium isotopes found in Pacific seabed sediments preserve evidence of an ancient cosmic explosion still traceable today
·Astronomers identified a potential superkilonova—a double cosmic explosion—as a previously unknown category of stellar death
