NASA’s James Webb Telescope reveals a sight to behold – a Supernova remnant

[ad_1] NASA's James Webb Space Telescope has imaged the SN 1987A, a distant supernova remnant in the Large Magellanic Cloud, 168,000 light-years away. Webb Telescope's NIRCam has uncovered intricate structures, outshining prior observations. With international collaboration from NASA, ESA, and the Canadian Space Agency, Webb aims to unravel cosmic mysteries using high-resolution imagery. Check out the highlights below: 1. SN 1987A, discovered in 1987, has been a subject of intensive research spanning nearly four decades, examined across various wavelengths from gamma rays to radio waves. 2. The James Webb Space Telescope's Near-Infrared Camera (NIRCam) has recently provided valuable insights into the evolution of supernovae and their remnants. 3. A notable discovery is a dense, keyhol...

Earth-like exoplanet with volcanoes found by NASA’s TESS and Spitzer telescopes

[ad_1] Scientists using NASA's TESS (Transiting Exoplanet Survey Satellite) and Spitzer Space Telescope have made a remarkable discovery —an Earth sized exoplanet orbiting a star in a neighbouring galaxy. This finding provides the strongest evidence to date of active volcanoes existing beyond our solar system. The observations indicate that this rocky planet has a rugged surface and experiences frequent eruptions, resembling Jupiter's moon Io, which is the most volcanically active body in our solar system. While the volcanism on the exoplanet wasn't directly observed, scientists inferred its presence from the gravitational interaction with the larger of the two planets also orbiting the star. The gravitational pull of the larger planet may cause the newly identified exoplanet to flex a...

Death of a star! Awesome tech helps NASA wind back the clock from 160,000 light years away

[ad_1] Astronomers have narrowed the timeline of a distant star's explosive demise with the help of NASA's Hubble Space Telescope and Chandra X-ray Observatory. Have you heard of stars exploding? Yes, the stars in the Milky Way and nearby galaxies do explode and astronomers have even seen the debris from scores of exploded stars. However, it is very difficult to determine or find out the timeline of the star's demise. But now NASA has informed that by studying the spectacular remains of a supernova in a neighboring galaxy using NASA telescopes, a team of astronomers has found enough clues to help wind back the clock. "By combining data from @ChandraXray, @NASAHubble, and the retired Spitzer Space Telescope astronomers have n...
