Imagine hearing a sound that began its journey before our galaxy even existed. That is what astronomers are doing now. They are picking up faint signals that have travelled for more than 13 billion years to reach Earth. These signals come from a time when the universe was still very …
The year 2025 has brought us a rare cosmic visitor. 3I/ATLAS is only the third confirmed interstellar object ever detected — after ʻOumuamua in 2017 and Comet Borisov in 2019. Discovered on July 1, 2025, by the ATLAS survey telescope, this object is on a hyperbolic orbit, meaning it came …
The universe holds endless mysteries, and today’s most powerful telescopes are helping us explore them like never before. These advanced instruments drive the progress of modern astronomy, using radio, infrared, optical, and X-ray wavelengths to capture light from ancient galaxies, black holes, exoplanets, and other distant objects. Built in extreme …
The NASA Roman Space Telescope, scheduled for launch in 2027, is a next-generation space observatory that will be used to complement and outdo the James Webb Space Telescope (JWST). It has been equipped with cutting-edge instruments and will keep humankind increasing its knowledge of the cosmos about dark energy and …
Trouble with one of the Hubble Space Telescope’s three remaining gyroscopes, critical for aiming and locking onto targets, has prompted mission managers to switch to a backup control mode that will limit some observations, but keep the iconic observatory running well into the 2030s, officials said Tuesday . “We still …
NEW DELHI: Astronomers have turned their gaze towards protoplanetary disks using the James Webb Space Telescope (JWST). These disks, composed of dust and gas, swirl around developing stars, offering crucial insights into the early stages of planetary birth.While numerous such disks have been studied, only two planets have been directly …
NEW DELHI: Nasa’s James Webb Space Telescope (JWST), a cornerstone in modern astronomical observation, is preparing to embark on a groundbreaking study of the auroras lighting up the polar skies of Uranus and Saturn. Researchers from the University of Leicester are at the helm of this venture, with the goal …
NEW DELHI: The cosmos presents a vast puzzle known as the “Hubble Tension,” defined by the discrepancy in the observed rate of the universe’s expansion compared to the expected rate, derived from initial conditions and current cosmological theories. This enigma has puzzled scientists who utilize tools like Nasa’s Hubble Space …
