Science Community Alarmed at NASA's Canceling of Major Lunar Mission
TEHRAN (ANA)- The U.S. National Aeronautics and Space Administration (NASA) has decided to end a major lunar mission due to delays and cost overruns, considered the latest setback in the agency's science efforts and raises concerns in the scientific community.
Astronomers Watch Supermassive Black Hole Turn On for First Time
TEHRAN (ANA)- Over the past four years, astronomers have been able to watch the supermassive black hole in SDSS1335+0728’s center go from dim and quiet to bright and active, the first time such a transition has been observed in real time.
Astronomers Develop New Observation Technique to Mitigate Asteroid Risks
TEHRAN (ANA)- A collaborative research team from China and Ukraine has been monitoring near-Earth asteroids (NEAs) through regular observations to attain accurate positioning and precise orbit determination for those celestial bodies.
NASA's Supersonic X-59 Aircraft Passes Milestone Test for 1st Flight
TEHRAN (ANA)- The U.S. National Aeronautics and Space Administration's (NASA) supersonic X-59 aircraft has completed a milestone review that will allow it to progress toward first flight, NASA said.
Researchers Develop New Algorithm to Recognize Coronal Mass Ejections
TEHRAN (ANA)- Researchers in China have developed a new algorithm to automatically derive kinematic parameters of coronal mass ejections (CMEs) based on machine learning.
Zombie Stars at Milky Way’s Core Defy Time
TEHRAN (ANA)- Northwestern University’s new research using simulations of 1,000 stars around the Milky Way’s supermassive black hole, Sagittarius A*, reveals that high-speed stellar collisions lead to the formation of youthful-looking stars.
What Is A Neutron Star?
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.
NASA’s DART Impact Changed Asteroid’s Shape, Orbit
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.
Scientists Discover Special Binary Gravitational Wave Source with Shortest Orbital Period
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.
Astronomers Detect Hidden Moons Orbiting Neptune, Uranus
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.
