TEHRAN (ANA)- Bubbles of radiation billowing from the galactic center may have started as a stream of electrons and their antimatter counterparts, positrons, new observations by scientists at Oakland University in Rochester suggest.

TEHRAN (ANA)- Sowjanya Gollapinni, a Senior Scientist in the Physics division at the US Department of Energy’s Los Alamos National Laboratory (LANL) in New Mexico, US, details the major collaborations in neutrino research helping to answer the great mysteries of the Universe.

TEHRAN (ANA)- A meandering trek taken by light from a remote supernova in the constellation Cetus may help researchers at the University of Copenhagen pin down how fast the universe expands — in another couple of decades.

TEHRAN (ANA)- Using Artificial Intelligence, an international team of researchers led by the University of Tokyo has found that the very first stars in the Universe were born in clusters rather than as isolated stars. 

TEHRAN (ANA)- A group of astrophysicists from Swinburne University of Technology have successfully revealed what the Universe was like 13 billion years ago after measuring carbon levels in the gases surrounding ancient galaxies.

TEHRAN (ANA)- Observations of water by scientists at the National Radio Astronomy Observatory (NRAO) in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own Solar System.

TEHRAN (ANA)- Searching through existing data spanning nine billion years, a team of researchers led by scientists at the University of Hawaiʻi at Manoa has uncovered the first evidence of ‘cosmological coupling’ – a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.

TEHRAN (ANA)- During a break from looking at planets around other stars, the European Space Agency’s CHaracterising ExOPlanet Satellite (Cheops) mission observed a dwarf planet in our own Solar System and made a decisive contribution to the discovery of a dense ring of material around it.

TEHRAN (ANA)- Researchers at the Imperial College London analyzed meteorites and uncovered the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life.

TEHRAN (ANA)- While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)— an international observatory co-operated by the US National Science Foundation’s National Radio Astronomy Observatory (NRAO)— scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy.
