Dramatic Planet Collision In Distant Galaxy May Explain How Earth's Moon Was Formed 4.5 Billion Years Ago
Scientists observe a dramatic collision between two planets, offering insights into the formation of Earth's Moon 4.5 billion years ago.

Astronomers Witness Rare Failed Supernova in Andromeda Galaxy
NASA’s NEOWISE infrared telescope has provided striking evidence that a massive star in the Andromeda galaxy collapsed directly into a black hole without exploding as a supernova. The star, M31-2014-DS1, faded dramatically in visible light while leaving a faint infrared glow from surrounding dust. Astronomers say this rare “failed supernova” ...

James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe
NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

James Webb Space Telescope Finds Most Distant Galaxy Ever Detected
The James Webb Space Telescope has discovered MoM-z14, the most distant galaxy ever observed, dating to just 280 million years after the Big Bang. The galaxy’s brightness, chemical richness, and structure challenge existing theories of early cosmic evolution. Scientists say the finding highlights a growing gap between models and observations of t...

Gravity May Behave Differently Across the Universe, Study Suggests
A new study suggests dark matter may not exist. Physicist Naman Kumar proposes gravity weakens differently across vast distances, following a 1/r rule. This modified gravity model reproduces galaxy rotation curves using only visible matter, challenging long-held assumptions about unseen mass in the universe, and reshaping theories of cosmic structu...

James Webb Telescope Discovers Most Distant Galaxy From Just 300 Million Years After the Big Bang
The James Webb Space Telescope has discovered the most distant galaxy ever observed, JADES-GS-z14-0, seen as it existed just 300 million years after the Big Bang. Its unexpected brightness and chemical complexity suggest rapid early star formation, challenging long-standing theories about how the first galaxies evolved in the early universe.

JWST Uncovers the Origins of the Universe’s First Supermassive Black Holes
James Webb Space Telescope observations reveal that the earliest supermassive black holes formed from massive gas clouds collapsing directly into heavy seeds. This process bypassed normal star formation, allowing black holes to reach millions of solar masses within just 200–500 million years after the Big Bang, solving a long-standing cosmic myst...

James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

New Dark Matter Simulation Could Change How Galaxies Are Thought to Evolve
Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter. The tool shows how rare dark matter interactions can heat and collapse galaxy halos, potentially explaining dense galactic cores and the early formation of supermassive black holes.

A Massive Black Hole Starved Pablo’s Galaxy, Ending Its Star Formation
Astronomers using the James Webb Space Telescope and ALMA have uncovered how a massive black hole shut down star formation in Pablo’s Galaxy. Powerful winds expelled gas at hundreds of kilometres per second, leaving almost no cold fuel behind. The findings suggest many early galaxies did not die explosively, but were slowly starved by their centr...
