#Repost///@nasahubble: Since 1990, Hubble has observed Supernova 1987A.Hubble's wide-field view shows a bright ring around the central region of the exploded star that's made of material cast off by the star about 20,000 years before its death.Working with observatories like the Spitzer Space Telescope and @NASAChandraXRay, Hubble's repeated observations of this fascinating target helped shed light on the final stages of stellar evolution.Now, @NASAWebb is unveiling new, exciting details about SN 1987A. Webb's powerful infrared vision reveals new details and structures, and aids our understanding of how a supernova evolves over time to shape its remnant.Hubble image credit: NASA, ESA, Robert P.

Big, bright stars in blue and red fill the image. At the center, a glowing red ring surrounds a bright point of light. Two additional glowing red rings loop around the top and bottom of the central ring.Webb image credit: NASA, ESA, CSA, M. Matsuura (Cardiff University), R. Arendt (NASA’s Goddard Spaceflight Center & University of Maryland, Baltimore County), C. FranssonWebb image description: The center of the image contains a dense green cloud, shaped like a keyhole. Within this keyhole, there is a dark spot, composed of even denser gas. Outside of this cloud of gas is a ring of dense orange gas and dust that becomes more diffused as it travels further away from the center. The innermost part of this dense orange ring contains brighter orange clumps of glowing gas. Outside of these structures, both above and below them, are very faint orange rings of gas and dust. There are several bright white stars, three of which show an eight-pronged diffraction pattern brought about by the Webb Space Telescope. Several other white stars are strewn throughout the image.#NASA #Hubble #Webb #supernova #space #stars #astronomy #universe #cosmos #telescope
