NASA's Europa Clipper spacecraft used its UVS instrument to observe the interstellar comet 3I/ATLAS from an unexpected vantage point, capturing unique data on its tails and composition, which may shed light on its origin and the processes shaping such comets from other star systems.
Astronomers using Hubble have discovered an ultra-massive white dwarf formed from a stellar merger, revealed by its ultraviolet spectrum showing carbon in its atmosphere, suggesting such merger remnants may be more common than previously thought.
Researchers using Hubble's UV data discovered that the high-mass white dwarf WD 0525+526 is likely the remnant of a stellar merger, evidenced by faint carbon signatures on its surface. This finding provides rare direct evidence of white dwarf mergers, which are important for understanding stellar evolution and supernovae, and highlights the importance of ultraviolet observations in detecting such phenomena.
