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 …
Dark matter makes up over 95 per cent of the universe, but it remains a mystery to date. Two scientists have now suggested that particles known as tachyons that move faster than light likely make up dark matter. Scientists Samuel H. Kramer from the University of Wisconsin–Madison and Ian H. Redmount from Saint Louis University …
Scientists from Lancaster University, the University of Oxford, and Royal Holloway, University of London are at the forefront of a groundbreaking effort to unravel one of the most perplexing enigmas in science. Dark matter, constituting approximately 80% of the universe’s matter, remains invisible to the human eye. Yet, it constantly permeates through us, potentially in …
A new theoretical research has made a stunning revelation that the Earth is currently crossing an ocean of dark matter and this invisible ocean’s waves have been slamming against the upper atmosphere of our planet and generating detectable radio waves. As per the research, these detectable radio waves have been helping in finally finding this universe’s elusive …
Jupiter again stunned the astronomers after they found the Great Red Spot on its surface with the help of the James Webb Space Telescope (JWST). The spot was unseen till now and came as a surprise to the scientists who suspected that it was caused by powerful atmospheric gravity waves. The Great Red Spot is now …
The general theory of relativity has been very successful at explaining gravity and an astonishing array of other related phenomena, such as gravitational waves, gravitational lensing, gravitational red shift, the existence of black holes, and time dilation. This theory refines Isaac Newton’s laws and provides a unified description of gravity as a geometric property of …
One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible matter, despite those laws working well everywhere in the Solar System. To prevent galaxies from flying apart, some additional gravity …
As part of NASA’s Mars Sample Return (MSR ) programme, the Perseverance rover has been collecting samples since it landed on the Red Planet in 2021, and the return was scheduled to happen in 2031. However, a NASA statement on April 15 suggests that the mission will have to be reworked with a simpler, less …
New Delhi: By observing motions of stars and gas across galaxies, researchers have found evidence that they said supports the existence of dark matter. While dark matter has not yet been directly detected and is therefore considered ‘invisible’, it is thought to explain various aspects of the observed universe. The findings on dark matter were …
The European Space Agency on Tuesday said that a few layers of water ice is starting to impact its Euclid spacecraft’s vision. The space agency is now working with others to test a newly-designed procedure to de-ice the spacecraft. Euclid is ESA’s “dark universe detective” and is designed to investigate how dark matter and dark …
