    Visual Description: Cassiopeia A & Crab Nebula Timelapses This is a still image from a split-screen video showing the change of two objects in space over time. The Cassiopeia A supernova remnant is on the left and the Crab Nebula is on the right, divided by a white vertical line. Cassiopeia A resembles a disk of electric blue light with glowing white streaks. X-rays from Chandra reveal hot gas, mostly from supernova debris from the destroyed star, and include elements like silicon and iron. Brilliant stars in white and gold, seen in optical light from Hubble, permeate the field of view. The Crab Nebula resembles the shape of a spinning toy top, made of white wispy clouds, resting on its side. The top-like shape is outlined by feathery shrouds of electric blue light...

    Webb Space Telescope Detects Universe’s Most Distant Complex Organic Molecules

    June 7, 2023, Categories  Astronomy/Space

    Astronomers using the Webb telescope discovered evidence of complex organic molecules in a galaxy more than 12 billion light-years away. The galaxy lines up almost perfectly with a second galaxy only 3 billion light-years away from our perspective on Earth. In this false-color Webb image, the foreground galaxy is shown in blue, while the background galaxy is red. The organic molecules are highlighted in orange.
