James Webb Telescope discovers signs of LIFE on exoplanet?

[ad_1] In a groundbreaking discovery, the James Webb Space Telescope has unveiled the secrets of K2-18 b, a distant world residing in the vast expanse of space far away from Earth. Astonishingly, scientists have identified the presence of carbon-based molecules, specifically methane and carbon dioxide, within the planet's enigmatic atmosphere. This celestial body, roughly 8.6 times the mass of our home planet Earth, has long been shrouded in mystery. Recent studies have hinted at a tantalising possibility – that K2-18 b's surface may be adorned with sprawling oceans of water, complemented by a hydrogen-rich veil of air. In effect, the Webb Space Telescope has revealed tantalising signs of life.K2-18 b's Celestial DanceK2-18 b traces its orbit around the enigmatic cool dwarf star, K2-18,...

Milky Way Galaxy and signs of life and water: Check out what this study found

[ad_1] A many as 1/3rd of the planets revolving around the most common stars across the Milky Way Galaxy may have liquid water and can possibly harbour life, according to a study based on latest telescope data. Most of the common stars in our galaxy are smaller and comparatively cooler. They are sporting just half the mass of the Sun at most. Billions of planets revolve around these common dwarf stars.Two-thirds of the planets around these ubiquitous small stars could be roasted by tidal extremes, sterilising them, shows the analysis which was published in the journal Proceedings of the National Academy of Sciences. Sheila Sagear, a doctoral student at the University of Florida (UF) in the US, said "I think this result is really important for the next decade of exoplanet research, becau...

Life on Mars killed off by Martians? Shocking study says so

[ad_1] A new study has revealed that the early life on Mars might have killed itself off. Know how the Martians caused their own end. For years, the word ‘Martian' has been a part of our vocabulary. The word simply means forms of life on the planet Mars. But the mainstream nature of the word, unlike Venutian (belonging to Venus) or Mercurian (belonging to Mercury) highlights how people on Earth have always believed in the possibility that life exists on Mars. And while NASA has not found any evidence of life existing at present, it has found evidence for microbial life on Mars that existed millions of years ago. And as scientists try to find out more about the life that existed on Mars, a new study has made a shocking claim. It says that the life of Mars was ended by the first organis...

Perseverance rover investigates geologically rich Mars terrain for signs of life

[ad_1] Perseverance rover is well into its second science campaign, collecting rock-core samples from features within an area long considered by scientists to be a top prospect for finding signs of ancient microbial life on Mars. NASA's Perseverance rover is well into its second science campaign, collecting rock-core samples from features within an area long considered by scientists to be a top prospect for finding signs of ancient microbial life on Mars.The rover has collected four samples from an ancient river delta in the Red Planet's Jezero Crater since July 7, bringing the total count of scientifically compelling rock samples to 12. "We picked the Jezero Crater for Perseverance to explore because we thought it had the be...

NASA Perseverance Mars Rover to dig deep into the Enchanted Lake in search for signs of Life

[ad_1] The NASA Perseverance Mars Rover will be visiting a site with sedimentary rocks called Enchanted Lake. Scientists believe that the site may show signs of ancient life on the red planet. NASA Mars Perseverance Rover has been collecting rock samples, analyzing the terrain, and hunting for evidence of previous microbial life on Mars since its landing in February 2021. Moving around the Jezero crater, it has found many interesting sights and shared them with scientists on Earth, but so far there have been no confirmed signs of life. However, that might be changing now as the rover is headed towards a site called Enchanted Lake. The location has an outcrop of sedimentary rocks and scientists believe that it might contain si...
