The Great Eta Carinae A Eruption was modeled by NASA with help from Hubble and Chandra
NASA teams have modeled in 3D the phenomenon of the Great Eruption of the star Eta Carinae A, in the Eta Carinae stellar system. Having taken place in 1838, the…
This Saturn moon would also hide an ocean under its surface
Around Saturn there was already Enceladus and Titan. Among the moons of the ringed planet that hide a liquid ocean under their surface, it will now probably also be necessary…
