TEHRAN (ANA)- For the first time, astronomers at Caltech have captured solid evidence of a rare double cosmic cannibalism — a star swallowing a compact object such as a black hole or neutron star.

TEHRAN (ANA)- A new study by the University of Barcelona found that after a short exposure to altered gravity, there were no significant changes in the defensive capacity of blood cells in the volunteers.

TEHRAN (ANA)- Researchers from the Universities of Bern and Geneva, as well as from the National Center of Competence in Research Planets, have shown for the first time that there are in fact four types of planetary systems.
