Unusual black hole found at universe’s dawn presents dusty mystery to astronomers

August 17, 2026 admin

When the James Webb Space Telescope looks deep into the Universe, some of the objects it finds appear as small, red dots. Astronomers call them little red dots (LRDs), and they have become one of the telescope’s more intriguing discoveries. Now, an international team of astronomers has found an unusual object that may help explain…

Astronomers Discover How Massive Black Holes Create Their Own Meals

January 28, 2025 admin

The universe’s most massive black holes fuel themselves by cooling gas around them, astronomers have found. Using data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) in Chile, researchers have demonstrated how black hole outbursts trigger a self-sustaining feeding process. The study, published in Nature Astronomy and led by Valeria Olivares from…

Astronomers build galaxy-sized ‘detector’ to map universe’s vibrations

December 31, 2024 admin

Using the largest gravitational wave detector ever made, we have confirmed earlier reports that the fabric of the universe is constantly vibrating. This background rumble is likely caused by collisions between the enormous black holes that reside in the hearts of galaxies. The results from our detector – an array of rapidly spinning neutron stars…

Astronomers Observe Black Hole That May Have Formed Gently

October 29, 2024 admin

Washington: The conventional wisdom among astronomers is that black holes – those exceptionally dense objects with gravity so powerful that not even light can escape – form in the violent explosion, called a supernova, of a massive dying star. But some, it turns out, may be born in a gentler fashion. Researchers have identified a…

Could rotating black holes be the wind turbines powering the distant future?

September 26, 2024 admin

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a…

Particles called quarks hold the key to the final fate of some stars

May 2, 2024 admin

We know that all matter is composed of atoms, and atoms are made of protons and neutrons inside the nucleus and electrons outside. But unlike electrons, protons and neutrons are composite particles because they are further made up of quarks. Quarks can’t exist in isolation. They can only be found in groups of two or…
