Webb Unlocks Secrets of Universe’s First Light
TEHRAN (ANA)- Utilizing data from NASA’s James Webb Space Telescope, scientists have unveiled the earliest starlight spectra, revealing low-mass galaxies’ central role in the universe’s dawn.
Astronomers Unveil Dark Matter’s Role in Galaxy Evolution
TEHRAN (ANA)- A research led by a team at the IAC has managed to confirm, for the first time using observations, the effect of dark matter on galaxy evolution.
Galaxies Exhibit Increasing Level of Chaos While Aging
TEHRAN (ANA)- A project led by the Australian research center ASTRO 3D has highlighted age as one of the most crucial drivers in how stars orbit within galaxies, suggesting that the arrangement of stars gets messier over time.
Mysterious Galaxy Already Dead When Universe Was Young
TEHRAN (ANA)- When a galaxy runs out of gas and dust, the process of star birth stops. That takes billions of years but, there's a galaxy out there that was already dead when the Universe was only 700 million years old, the University of Cambridge found.
Our Universe Isn't as Clumpy as It Used to Be
TEHRAN (ANA)- A big problem concerning the Universe's dark matter has just grown a little more intense and observations of the more recent Universe by scientists at Princeton University reveal that this elusive material is distributed differently compared to measures of its spread just after the Big Bang.
Surprising Eating Habits of Black Holes
TEHRAN (ANA)- Scientists have revealed that the energy generated by the high temperature of the material accumulated around the black hole destroys the molecular gas and transforms it into atoms and plasma.
Researchers Study over 1 Million Galaxies to Find Out How Universe Began
TEHRAN (ANA)- Researchers from Kavli Institute for the Physics and Mathematics of the Universe have analyzed more than one million galaxies to explore primordial fluctuations that seeded the formation of the structure of the entire universe.
How Three Mysterious Young Stars Can Shed Light on Early Universe
TEHRAN (ANA)- Through analysis of high-resolution data from a ten-metre telescope in Hawaii, researchers at Lund University in Sweden have generated new knowledge about three young stars at the very heart of the Milky Way.
Webb Spots Milky Way’s Twin in Early Universe
TEHRAN (ANA)- Astronomers using the James Webb Space Telescope, have discovered ceers-2112, the most distant barred spiral galaxy observed to date.
New Study Reveals Origin of Ultra-Compact Dwarf Galaxies
TEHRAN (ANA)- A research team led by Chinese astronomers has, for the first time, observed the complete process of dwarf galaxies evolving into ultra-compact dwarf galaxies (UCDs).
