'Troublesome' radio galaxy 32 times the size of Milky Way spotted

Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way.

Fast radio burst in long-dead galaxy puzzles astronomers

Fast radio bursts (FRBs) are puzzling phenomena because their details are so difficult to resolve. Astronomers added another piece to the puzzle with the detection of an FRB that seems to originate in a dead galaxy.

X-ray flashes from a nearby supermassive black hole accelerate mysteriously

MIT astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.

Beyond the 'Dragon Arc,' a treasure trove of unseen stars

Taking advantage of a cosmic "double lens," astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.

Astronomers discover an ultra-massive grand-design spiral galaxy

Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. 

Hubble Views Supernova-Hosting Spiral Galaxy

NASA has released a beautiful photo taken by the NASA/ESA Hubble Space Telescope of the spiral galaxy LEDA 22057.

We Just Got an Extreme Close-Up of One of The Universe's Brightest Objects

Using the Hubble Space Telescope, astronomers homed in on a quasar called 3C 273, some 2.5 billion light-years from Earth.

Here's what the James Webb telescope has found in just 3 years

The James Webb Space Telescope is celebrating three years from its launch. Its discoveries have already changed our understanding of the early universe.

Galaxy NGC 5084 black hole is tipped on its side

There's a supermassive black hole lying in the centre of galaxy NGC 5084, and astronomers have discovered that the black hole appears to be tipped over on its side.

Supermassive black holes halt rapid construction in an ancient celestial city

Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut down star formation. 

Astronomers close to solving mystery of how universe's giant galaxies formed

Astrophysicists find the birth sites of gigantic elliptical galaxies which they say gives new clues about how they were formed. The galaxies look like bulging footballs and how they were created remains a mystery to scientists -- until now.

Giant Study Confirms The Milky Way Really Is an Unusual Galaxy

The Milky Way is only one system and may not be typical of how other galaxies formed. That's why it's critical to find similar galaxies and compare them

Mysterious Ultra-Massive Galaxies Spotted in Early Universe

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies -- nearly as massive as our own Milky Way Galaxy - already in place within the first billion years after the Big Bang.

Mysterious 'Interstellar Tunnel' Found in Our Local Pocket of Space

Our star resides in the Local Hot Bubble (LHB). Now a team of astronomers has mapped the bubble, revealing the presence of a mysterious tunnel pointing towards the constellation Centaurus.

Giant Magnetic Halo Discovered Wrapped Around The Milky Way

By studying hot gas glowing in circumgalactic space, astrophysicists have found evidence of enormous magnetic fields that wind through and around our galaxy's dark matter 'halo'.
