TEHRAN (ANA)- A neutron star was formed in the last moments of the life of a very large star (with more than about eight times the mass as our Sun), when the nuclear fuel in its core eventually ran out.

TEHRAN (ANA)- After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk.

TEHRAN (ANA)- Scientists at Tsinghua University recently discovered a binary star system consisting of a white dwarf and a hot subdwarf which were monitored orbiting each other at a record-breaking speed.

TEHRAN (ANA)- Jupiter and Saturn need to step aside with their moon-hogging ways and the outer planets of the Solar System have also been harboring secret satellites, scientists at the Carnegie Institution for Science say.

TEHRAN (ANA)- Astronomers have discovered that stars like the Sun experience a significant reduction in magnetic braking as they age, altering our understanding of star evolution and the potential for habitable environments around older stars.

TEHRAN (ANA)- Cargo mission preparations and space research kept the Expedition 70 and Axiom Mission 3 (Ax-3) crews busy and the 11 residents working together aboard the International Space Station (ISS) also continued their ongoing biomedical science and lab maintenance activities.

TEHRAN (ANA)- The first flight of NASA's commercial lunar delivery service carrying agency science and technology, as well as other customer payloads intended for the Moon, has come to an end, NASA confirmed.

TEHRAN (ANA)- NASA and SpaceX are targeting mid-February to launch the eighth crew mission to the International Space Station (ISS), the agency said.

TEHRAN (ANA)- Researchers at the Center of Excellence in Space Sciences India at IISER Kolkata have discovered a new relationship between the Sun’s magnetic field and its sunspot cycle that can help predict when the peak in solar cycles will occur.

TEHRAN (ANA)- A star in the Pinwheel galaxy exploded in just the right place at nearly the right time for astronomers to unravel details of its death and it was the closest supernova to go off in the last five years.
