Transient and explosive astronomical phenomena constitute a research area focused on short-lived, high-energy events in the universe, such as supernovae, gamma-ray bursts, tidal disruption events, kilonovae, and fast radio bursts. This field investigates the underlying physical mechanisms driving rapid energy release, including relativistic jets, shock breakout, nucleosynthesis, compact object mergers, and accretion-induced instabilities. Research integrates multiwavelength and multimessenger observations (electromagnetic spectra, gravitational waves, neutrinos) with numerical simulations and theoretical modeling to constrain progenitor systems, energy budgets, radiative transfer processes, and environmental impact, including feedback on galactic evolution and the production of heavy elements.
Elon Musk's SpaceX announced Friday that its Starship megarocket is scheduled to blast off on a new test flight next weekend after recent attempts have ended in fiery explosions.

Using various telescopes worldwide, an international team of astronomers has observed a tidal disruption event (TDE) known as AT2018hyz, which allowed them to witness a rapid brightening of this source in the radio band.
Scientists predict one of the major surveys by NASA's upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence ...
