First Euclid Images Reveal Billions of Orphan Stars Orbiting an Intriguing Point Between the Galaxies from Which they Were Ejected

The Euclid satellite’s first scientific images have unveiled over 1.5 trillion orphan stars scattered throughout the Perseus galaxy cluster. This discovery, led by astronomers from the University of Nottingham, sheds new light on the origins of these wandering celestial bodies. Located 240 million light-years from Earth, the Perseus cluster is one of the most massive […]

What is the Origin of Phosphorus and why is it so Abundant? Astronomers Propose it Formed in Nova Explosions 8 Billion Years Ago

Phosphorus is one of the essential elements for life on Earth, it plays a critical role in DNA, RNA, ATP, and other biological molecules. Yet, its origins in the universe have puzzled scientists for years. Now, a new theory suggests that the abundant presence of phosphorus on Earth might be tied to a specific type […]

Greatest Explosion Recorded since the Big Bang Unlocks a New Cosmological Mystery

In October 2022, an international team of researchers, including astrophysicists from Northwestern University, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. Now, a team led by Northwestern has confirmed that the phenomenon responsible for this historic burst, nicknamed the “Brightest of All Time” (B.O.A.T.), is the collapse and subsequent explosion of a massive […]

Scientists Propose the Existence of Gravastars or Gravitational Stars Nested Inside Each Other

Black holes continue to mystify scientists. In 1916, German physicist Karl Schwarzschild proposed a solution to Albert Einstein’s general relativity equations suggesting that the center of a black hole contains a “singularity” — a point where space and time cease to exist. According to theory, within the singularity all physical laws, including Einstein’s general relativity, […]

First-ever Observation of a Supermassive Black Hole Preventing Star Creation in a Galaxy at the Dawn of the Universe

A quasar is a compact region powered by a supermassive black hole located at the center of a massive galaxy. They are extremely bright, with a pinpoint appearance similar to stars, and are far away from Earth. Due to their distance and brightness, they allow a glimpse into the conditions of the early Universe, when […]

Astronomers Discover a Type of Star Emitting Smoke Clouds in the Heart of the Milky Way

Astronomers have discovered stars that were hiding in plain sight within our Milky Way galaxy. An international team of scientists observed nearly one billion stars over 10 years using infrared light, which allowed them to see through dust and gas and find stars that were previously invisible. Some of the stars they discovered were newly […]
