In Arizona, at Kitt Peak National Observatory, a telescope has spent three years building a three-dimensional map of the heavens. In examining the light from tens of millions of galaxies, the Dark Energy Spectroscopic Instrument (DESI) may have found something astounding. DESI, as its name suggests, is a tool to investigate the nature of dark …
Our universe is expanding and the reason for it might be the existence of an anti-universe. This is something similar to what we know in the world of sci-fi as multiverse – the existence of multiple worlds, or two universes in this case. Naman Kumar, a PhD student at the Indian Institute of Technology (IIT), …
London: Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk – walking on the edge of a very dangerous cliff. And it’s all down to the instability of a single fundamental particle: the Higgs boson. In new research by my colleagues and, …
The European Space Agency (ESA) satisfies the curiosity of space lovers by sharing intriguing posts that give a glimpse into the world beyond our home planet. One such post shows “first-ever star clusters” from 460 million years after the Big Bang. The ESA shared a visual showing “the first-ever star clusters” from 460 million years …
he James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday. Since coming online in 2022, the Webb telescope has ushered in a new era of scientific breakthroughs, …
One of the most critical parameters for comprehending the expansion of the Universe is the Hubble constant or the Universe’s expansion rate. However, there is a constant discrepancy between the observed and expected values from the Big Bang’s afterglow, known as the Hubble Tension. The Hubble and James Webb space telescopes confirmed the accuracy of …
Following is a summary of current science news briefs. Stone tools in Ukraine offer oldest evidence of humans in Europe A dating method based on cosmic rays has identified stone tools found in western Ukraine as the oldest-known evidence of human occupation in Europe – 1.4 million years ago – showing that the peopling of …
Updated Jan 19, 2024, 04:09 PM IST Astronomers using the James Webb Space Telescope have discovered the oldest and most distant black hole ever observed. This cosmic behemoth, nicknamed GN-z11, lurks within a fledgling galaxy a staggering 13.4 billion light-years away, placing it just 440 million years after the Big Bang – the universe’s explosive …
When a violent shake of space-time hit the Earth on August 17, 2017, it was not only possible to measure gravitational waves for the first time, which had previously only existed in theory. It also provided scientists around the world with countless pieces of valuable data. And the source of the gigantic explosion was identified …
Astrophysical Chaos: What happens if you put a black hole into the Sun? Long ago, there were tiny black holes called primordial black holes in the early Universe. They came in various sizes, from as small as an asteroid to as big as thousands of suns. These black holes might be part of what we …
