NASA's James Webb Space Telescope Shows 3D Structure Of Dust And Gas Between Stars
NASA's James Webb Space Telescope has captured highly detailed images showing the complex layers of interstellar dust and gas. These observations, collected through light echoes from a supernova explosion, "are allowing astronomers to map the true 3D structure of this interstellar dust and gas (known as the interstellar medium) for the first time," stated NASA in a release. The light echoes, originating from a star's collapse over 350 years ago,…
Webb sees shockwave continuing hundreds of years after supernova blast
Scientists have probed the remains of a star that died in a violent supernova and discovered that its shockwave continued reverberating through space, hundreds of years later.That shockwave eventually reached interstellar space, the medium that fills regions between stars. Researchers used the James Webb Space Telescope, a collaboration of NASA and its European and Canadian counterparts, to find that the ancient pulse, like a cosmic flashlight, …
Webb reveals intricate layers of interstellar dust and gas
Once upon a time, the core of a massive star collapsed, creating a shockwave that blasted outward, ripping the star apart as it went. When the shockwave reached the star's surface, it punched through, generating a brief, intense pulse of X-rays and ultraviolet light that traveled outward into the surrounding space. About 350 years later, that pulse of light has reached interstellar material, illuminating it, warming it, and causing it to glow in…
