Complex Structure And Well-Organized At Such An Early Stage Of The Universe Surprises Scientists And May Rewrite Part Of The History Of Galactic Formation
Astronomers Made A Surprising Discovery Using The James Webb Space Telescope. They Identified A Gigantic Spiral Galaxy, Named Zhúlóng, That Existed Only One Billion Years After The Big Bang. The Revelation Contradicts Previous Theories About Galaxy Formation.
Zhúlóng: A “Distant Dragon”
Zhúlóng, A Name That Means “Torch Dragon”, Is The Most Distant Disk Galaxy Ever Observed With Spiral Arms And Disk Structure. It Features A Central Bulge, Well-Defined Spiral Arms, And A Star Formation Disk. These Characteristics Are Normally Associated With Closer Galaxies Formed Billions Of Years Ago.
According To Researcher Mengyuan Xiao From The University Of Geneva (UNIGE), The Disk Of Zhúlóng Is Over 60,000 Light-Years Across And Contains More Than 100 Billion Solar Masses In Stars. The Size And Mass Of The Galaxy Are Comparable To Those Of The Milky Way.

Scientists warn that getting pregnant could become more difficult in the future because extreme heat, microplastics, PFAS, and other toxic substances can act together in the body and affect hormones, human reproduction, and fertility.

Rains of almost 200 mm devastate Pernambuco and Paraíba in less than 24 hours, leaving six dead, 2,190 displaced, breaking 30-year rainfall records, and causing landslides that buried a mother and a six-month-old baby in Olinda, while almost 500 people needed to be rescued after being stranded by the floods.

A cold air mass gains strength, turns into a cold wave, and could drop temperatures in the South and Southeast for several days, with a peak between May 12 and 13, advancing close to the central region of Brazil, and a risk of storms before the weather change.

Scientists reveal a surprising phenomenon in which darkness surpasses the speed of light and challenges fundamental concepts of modern physics and the theory of relativity.
New Vision Of The Universe
The Discovery Raises Questions About Galaxy Formation. For A Long Time, It Was Believed That Massive Spiral Galaxies Took Billions Of Years To Form.
It Was Expected That Galaxies In The First Billion Years Of The Universe Would Be Small, Irregular, And Disorganized. But Zhúlóng Displays A Mature Structure At A Time Considered Very Early.
The Galaxy Was Identified At A Redshift Of 5.2, Indicating Its Enormous Distance And Antiquity. The Infrared Images Captured By The Webb Telescope Are Changing The Way Scientists Understand The Dawn Of The Universe.
PANORAMIC Program And The Future Of Discoveries
Zhúlóng Was Found During The PANORAMIC Survey, Which Is Focused On The Detection Of Rare And Distant Objects. Astronomer Christina Williams From NOIRLab Highlighted The Potential Of This Type Of Research To Challenge Current Models Of Galaxy Formation.
According To Professor Pascal Oesch From UNIGE, This Is One Of The Discoveries That Shows How The Webb Telescope Is Radically Transforming The Scientific View Of The Primitive Universe. The Complete Research Was Published In The Journal Astronomy & Astrophysics.
