| 説明 | To: You, From: The Universe 🎁This beautiful new image from Webb is a gift from a past star. In near-infrared light, supernova remnant Cassiopeia A (Cas A) resembles a shiny ornament.With its powerful vision, Webb can detect the tiniest knots of sulfur, oxygen, argon and neon gas from the star. Embedded in the gas are dust and molecules that will eventually become part of new stars and planets.See that blob in the bottom right? Scientists have nicknamed it Baby Cas A since it looks like a tiny version of Cas A itself. Baby Cas A is a light echo: Light from the supernova has reached and is warming the distant dust in this blob. Although Baby Cas A appears very close to Cas A, it’s actually about 170 light-years behind the supernova remnant.Since its launch nearly two years ago, Webb has consistently awed us with its wondrous views of the universe. We’re looking forward to a new year of stunning science and imagery to come.Read more: go.nasa.gov/41iVsJdCredit: NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (Ghent University)Image description: Cassiopeia A, a round cloud of gas and dust with complex structure. The inner shell is made of bright pink and orange filaments studded with clumps and knots. Around the exterior of the inner shell, particularly at the upper right, there are curtains of wispy gas that look like campfire smoke. The white smoke-like material also appears to fill the cavity of the inner shell, featuring structures shaped like large bubbles. Around and within the nebula, there are various stars seen as points of blue and white light. Outside the nebula, there are also clumps of yellow dust, with a particularly large clump at the bottom right corner that appears to have very detailed striations. |
