Hubble Tension: NASA’s James Webb Telescope, Hubble Space Telescope to find out truth about Universe’s expansion rate

[ad_1] Scientists believe that our universe is expanding at a rapid rate, but there is a problem. A puzzle of sorts is there and it needs to be solved which is called the "Hubble Tension," it avers that the current rate of the expansion of the universe is faster than what astronomers expect it to be. Therefore, to understand the Universe's expansion rate, NASA's James Webb Telescope and Hubble Space Telescope have joined hands to find the inconsistency in measurements. The telescope's high-resolution data will help researchers study the puzzle and find out what really is happening with our Universe. Check out how cosmologists are planning to solve the errors and bring accuracy. Universe expansion rateAccording to a NASA report, the Hubble Space Telescope has been studying the current ex...

NASA’s James Webb Space Telescope discovers a record-breaking tiny Brown Dwarf! Know all about it

[ad_1] James Webb Space Telescope run by NASA has helped scientists discover various mysteries of the cosmic world going as far back in time that is extremely close to the Big Bang itself. In a recent groundbreaking discovery, James Webb Space Telescope has identified the smallest free-floating brown dwarf ever observed. NASA scientists have found this smallest object that can form in a star-like manner. Read here to know all about the newly discovered brown dwarf.What are brown dwarfs?As explained by NASA, Brown dwarfs are celestial objects straddling the line between stars and planets. They are born just like stars. They grow dense enough and then they collapse under their own gravity. However, they never become dense and hot enough for hydrogen fusion and turn into a star.

James Webb Space Telescope just unraveled mystery of vanishing neon, NASA says

[ad_1] In a groundbreaking revelation, the James Webb Space Telescope (JWST) has observed a significant transformation in a planet-forming disk, shedding light on the fleeting nature of these cosmic nurseries. NASA says that unlike traditional observations that capture planetary disks as static snapshots over vast timescales, the James Webb Telescope has offered a dynamic glimpse into the evolution of one such disk. The Neon Puzzle UnveiledBack in 2008, researchers led by Catherine Espaillat, then at the University of Michigan and now at Boston University, detected a distinctive infrared emission line associated with doubly ionized neon ([Ne III]) in the planet-forming disk encircling the young star SZ Chamaeleontis (SZ Cha) using NASA's Spitzer Space Telescope, Space.com reported.

James Webb Space Telescope reveals amazing cosmic water delivery system

[ad_1] In a cosmic twist, the James Webb Space Telescope (JWST) has unveiled a celestial supply chain involving ice-covered pebbles shuttling water to newly forming planets around young stars. This groundbreaking discovery challenges traditional beliefs about the origin of Earth's water and sheds light on the interconnectedness of solar system regions from its far regions to its very centre. The JWST's unparalleled vision penetrated the dust and gas surrounding four young stars, exposing protoplanetary disks- dense gas formations encircling nascent stars. Remarkably, the telescope identified an excess of water vapor in the inner regions of two disks, hinting at the presence of icy pebbles ferrying water to developing planets closer to their host stars, according to a Weather.com report....
