Elementos como ouro e platina são formados em alguns dos eventos mais poderosos do Universo, como a fusão de estrelas de nêutrons maciças: cientistas identificaram um desses eventos em estrutura remanescente de uma colisão de galáxias nos confins do Universo. ESO/L. Calçada/M. Kornmesser

Astrofísicos rastreiam a origem de metais preciosos no espaço

Ouro e platina, entre outros elementos, são criados quando duas estrelas maciças colidem

Astrophysicists trace the origin of valuable metals in space, from colliding stars to merging galaxies

Gold and platinum are found in space, created when two stars collide. Astrophysicists can even trace this process further back, to the merger of galaxies.
When two neutron stars merge and create a black hole, they produce a powerful blast of gamma rays. A. Simonnet (Sonoma State Univ.) and NASA’s Goddard Space Flight Center

Unusual, long‑lasting gamma‑ray burst challenges theories about these powerful cosmic explosions that make gold, uranium and other heavy metals

Eleonora Troja, University of Rome Tor Vergata and Simone Dichiara, Penn State

Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
