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 […]

James Webb Telescope Shows Most Galaxies in the Early Universe Were Long and Thin, not Spherical or Disk-shaped
Scientists have been using NASA’s space telescope James Webb to learn about galaxies from long ago. Way back then, when the universe was just getting started, most galaxies didn’t look like the spiral shapes we see today. The researchers found that a huge number of early galaxies were thin and flat, like surfboards lying on […]

Another Mysterious Ultra-large Structure in Deep Space, a Large Ring 4 Billion Light-years in Circumference, Discovered by Astronomers
A doctoral student in the United Kingdom has made an unexpected discovery that challenges some basic assumptions in cosmology. Alexia Lopez, a student at the University of Central Lancashire, has found evidence of an immense ring-like structure in the distant universe. Known as the Big Ring on the Sky, it is over 9 billion light-years […]

Astronomers Discover Origin of Rare Radio Circles in Universe
Astronomers don’t usually say “What’s that?” when looking at the night sky. They know what most things are like stars, planets, black holes and galaxies. But in 2019, a new radio telescope called ASKAP saw something it had never seen before – huge circles made of radio waves, with whole galaxies inside them. Scientists wanted […]

An ultra-high energy cosmic ray from an unknown location in space impacted the Earth
A high-energy particle fell from space and hit the Earth’s surface, but its origin and exact nature are unknown. This may sound like science fiction, but it’s a real scientific discovery, according to research led by Associate Professor Toshihiro Fujii of Osaka Metropolitan University’s Faculty of Science and Institute for Theoretical and Experimental Physics. Cosmic […]

A Strange New Cosmic Phenomenon Puzzles Scientists
Astronomers have discovered an unusual and extraordinary new space phenomenon – repeated energetic flare-ups observed over several months following the explosive death of a distant star. Led by researchers at Cornell University, a study published in November 2022 in Nature details this previously unseen activity. The brief but bright flashes – lasting only minutes but […]

Scientists Detect Long-Lasting Radio Emissions from a Solar Spot
Scientists have made detailed radio observations of an unusual aurora-like phenomenon occurring 40,000 km above a relatively dark and cool area of the Sun known as a solar spot. Using the Karl G. Jansky Very Large Array, a team from the New Jersey Institute of Technology’s Center for Solar-Terrestrial Research (NJIT-CSTR) observed polarized radio bursts […]

Astronomers discover a galaxy that looks a lot like the Milky Way
Using a powerful new telescope called the James Webb Space Telescope, astronomers have discovered the most faraway barred spiral galaxy that looks like our home Milky Way galaxy. This galaxy formed not too long after the Big Bang, when the universe first began. The galaxy’s name is ceers-2112. It has a bar shape made of […]
