We understand dark matter and dark energy as those invisible things in space that we can’t see but know are out there. As per the scientists dark matter helps hold galaxies together, and dark energy is somehow making the universe expand faster. 

Imagine building a huge group of telescopes on the Moon, where there’s no air or weather to interfere, allowing us to see further into space than we ever could before. That’s the idea behind the Artemis-enabled Stellar Imager (AeSI), a proposed lunar interferometer designed to reveal what’s happening on the surfaces of stars and deep inside active galactic nuclei (AGN). A team led by Dr. Kenneth Carpenter at NASA’s Goddard Space Flight Center recently completed a nine-month feasibility study, and their findings suggest that this ambitious idea is not just…

The James Webb Space Telescope (JWST) has revolutionized our understanding of the early universe, particularly with its discoveries in 2024. The objects that have been discovered have revealed properties and structures that challenges our current understanding of cosmic theories. These groundbreaking findings, many made possible by the phenomenon of gravitational lensing, have opened new avenues of research into how the earliest galaxies and stars formed.

Somewhere in 1916, Albert Einstein figured out his theory about gravity that there are waves in the fabric of spacetime. Also known as ripples. Since then, scientists have been working out what these waves would look like in a few basic situations, like merging of two black holes.

Launched in 1977, Voyager 1 is one of the farthest probes that we’ve sent so far. As of July 2024, it’s a whopping 24.4 billion kilometers away from Earth, making it the most distant human-made object ever. Yet, there are things in the space that we have absolutely zero clue. Yes, I’m referring to – Dark Matter. Dark matter helps slow the black holes down and lets them come together for supermassive black hole mergers, at least the recent research says so. Typically elusive, this invisible matter seems to play…

Scientists from Skoltech and their Chinese colleagues have discovered conditions that might allow for the existence of a unique ion called aquodiium. This ion is essentially a water molecule that has gained two extra protons. This means, the “regular” H₂O formula with two additional protons (H⁺), will make its chemical formula H₅O²⁺.

Detecting gravitational waves have always been a challenging task. It is caused due to high energetic events, like colliding black holes or neutron stars. And so, the phenomenon is like ripples on the fabric of space-time. By the time, this effect reaches us (from deep space), the signals become extremely weak. And hence, too faint to detect.   

Exciting news from the cosmos! Astronomers from around the world, including the brains at The University of Manchester and the Max Planck Institute for Radio Astronomy in Germany, have stumbled upon an unknown object in the Milky Way. The newly discovered object is heavier than the heaviest neutron stars we know. And lighter than the lightest black holes we’ve seen. The team used the MeerKAT Radio Telescope, to spot this mysterious object. This celestial entity is in orbit around a high-speed millisecond pulsar, situated around 40,000 light years away in…

Recently, astronomers have detected a super-old black hole, which is devouring its galaxy. It is dated back to the earliest black hole ever. It’s like the ultimate space buffet for the oldest black hole. Researchers at the University of Cambridge, unleashed the NASA/ESA/CSA James Webb Space Telescope (JWST) to spot this ancient black hole. The gravity well is chilling out 400 million years post-Big Bang, that is, over 13 billion years back.

Indian and Taiwanese astronomers recently upgraded Giant Metrewave Radio Telescope (uGMRT) to snoop around the galaxy cluster Abell 2108. And guess what? They stumbled upon a second, way bigger radio relic that’s like, totally different from the first one they knew about in the same cluster.
