WASHINGTON: Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.Using data from the James Webb Space Telescope (JWST), the astronomers, led by the University of Cambridge, have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), in the atmosphere of the…

Scientists have struggled for many decades with a cosmological conundrum known as the Hubble tension—a persistent disagreement in how quickly the universe is expanding as inferred from observations made using different methods. The disagreement arises because different methods of estimating the expansion of the universe yield different measurements. On one hand, observations on galaxy and…
In a potential breakthrough in the search for extraterrestrial life, a team of researchers led by Indian-origin astrophysicist Dr. Nikku Madhusudhan has reported compelling evidence of biological activity on a distant exoplanet, K2-18b, located 120 light-years from Earth. The discovery is centered around the detection of dimethyl sulfide (DMS), a molecule that, on Earth, is…
In a historic moment for marine science, researchers have captured the first-ever live footage of a colossal squid in its natural deep-sea habitat. The incredible discovery was revealed on Tuesday by the Schmidt Ocean Institute, which led an international expedition in the South Atlantic Ocean using a remotely operated underwater vehicle.The squid filmed was a…
NASA has released an image of a mysterious, 328-foot-wide hole on Mars, describing it as a potential “portal” to underground caves that may support alien life. The image, originally captured by the Mars Reconnaissance Orbiter in 2017, was shared on April 13 as part of NASA’s Astronomy Picture of the Day. Scientists believe such pits…

Astronomers from the University of Cambridge have uncovered promising signs that a planet orbiting a distant star could be home to life, reports BBC. The planet, K2-18b, lies a staggering 700 trillion miles away, yet powerful observations from Nasa’s James Webb Space Telescope (JWST) are bringing it into scientific focus like never before.The team, led…
