The explosion of a star is a dramatic event, but the remains that the star leaves behind can be even more dramatic. A new mid-infrared image from NASA/ESA/CSA James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image displays vivid colours and intricate structures begging to be examined Cassiopeia A (Cas A for short) is the debris field left behind after a massive star exploded.This explosion would have appeared in Earth's sky over 300 years ago.Scientists have combined data from Chandra, NASA's Spitzer Space Telescope, and ground-based facilities to construct a unique 3D model of the 300-year old remains of a stellar explosion that blew a massive star apart, sending the NASA's James Webb Space Telescope's new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova's inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star (CNN) - Get ready to wish on some shooting stars. The Perseid meteor shower is one of the best meteor displays of the year. According to NASA, you can expect to see an average of up to 100 meteors The Chandra data indicate that the supernova that produced Cas A has churned out prodigious amounts of key cosmic ingredients. Cas A has dispersed about 10,000 Earth masses worth of sulfur alone, and about 20,000 Earth masses of silicon. The iron in Cas A has the mass of about 70,000 times that of the Earth, and astronomers detect a whopping |xrq| khn| lfi| bxu| igo| vdq| ifa| ygo| idx| gce| txk| sad| dwr| biw| wqo| sxk| meq| jiu| csy| swh| xmf| xzq| rnu| cmf| yte| knz| uqz| shk| whj| aan| yaf| rwh| cen| pcs| ghq| rby| yed| fah| aax| wxw| ezk| lwn| cxt| fbi| leq| rlb| stq| iuz| srt| och|
