Webb Telescope Reveals Milky Way’s Ancient Twin Sparkling from Cosmic Dawn
TEHRAN (ANA)- NASA’s James Webb Space Telescope has discovered a galaxy named Firefly Sparkle, existing just 600 million years post-Big Bang and bearing similar mass to the early Milky Way.
Astronomers Discover Spheroid Formation Process in Early Universe
TEHRAN (ANA)- An international team of astronomers has discovered the formation process of in situ spheroids in distant starburst galaxies in the early universe.
Scientists Uncover New Clues about Alien Life
TEHRAN (ANA)- Researchers have developed a model indicating that our universe’s conditions for life, influenced by dark energy density, are not ideal, although life remains viable and this suggests a reevaluation of the cosmic factors essential for life.
Scientists Finally Uncover Mysterious Origin of Most Meteorites
TEHRAN (ANA)- Researchers found that 70% of meteorites originate from three asteroid families formed by recent collisions and they have identified the sources of over 90% of all known meteorites.
Black Hole Mergers Hiding Mysterious New Particles
TEHRAN (ANA)- Merging black holes may reveal new particles through gravitational waves, either via ionization or specific orbital changes which offers new strategies to search for ultralight particles.
Astronomers Discover Record-Breaking Twin Quasars in Early Universe
TEHRAN (ANA)- Astronomers have identified the earliest pair of quasars, shining 900 million years post-Big Bang, revealing insights into galaxy mergers and the reionization era of the Universe.
Researchers Uncover Unexpected Origin of Dinosaur-Killing Asteroid
TEHRAN (ANA)- A study led by the University of Cologne identified the origin of the asteroid that wiped out the dinosaurs as being from outside Jupiter’s orbit.
Scientists Reveal Patterns in Earth's Rotational Deceleration over Millions of Years
TEHRAN (ANA)- Chinese researchers, in collaboration with counterparts from France, Germany and Ireland, have discovered that between 650 million and 280 million years ago, the Earth-Moon distance increased by approximately 20,000 km, and the length of a day extended by roughly 2.2 hours.
Astronomers Develop New Technique to Extract Information from Galaxies
TEHRAN (ANA)- A new research method developed by NAOC scientists improves the extraction of complex galaxy data, paving the way for future cosmic explorations and surveys.
Protoplanetary Puzzles Solved at Hyper Speed
TEHRAN (ANA)- Researchers have developed a new model for planet formation that shows how disturbances in protoplanetary disks can quickly form gas giants and this process is more efficient than previously thought and aligns with recent observations of distant gas giants.
