APOD: 2023 November 15 - M1: The Incredible Expanding Crab Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 November 15 M1: The Incredible Expanding Crab Image Credit:NASA, ESA, CSA,STScI;Jeff Hester (ASU), Allison Loll (ASU), Tea Temim (Princeton University) Explanation: Cataloged as M1,the Crab Nebula is the first onCharlesMessier's famous list of things which arenot comets.In fact, the Crab Nebula isnow known to be a supernova remnant, an expandingcloud of debris from the death explosion of a massive star.The violent birth of the Crab was witnessedby astronomers in the year 1054.Roughly10 light-years across,the nebula is still expandingat a rateof about 1,500 kilometers per second.You can see the expansion bycomparing these sharp images from theHubble Space Telescope and James Webb Space Telescope.The Crab's dynamic, fragmented filaments were captured in visiblelight by Hubble in 2005 and Webb in infrared light in 2023.This cosmic crustaceanlies about 6,500 light-years away in theconstellation Taurus.

Frattare & K. Arcand Explanation: Dominated by dark matter,massive cluster of galaxies Abell 2744 is known to some asPandora's Cluster.It lies 3.5 billion light-years away toward the constellation Sculptor.Using the galaxy cluster's enormous mass as a gravitational lensto warp spacetime and magnify even more distant objectsdirectly behind it, astronomershave found a background galaxy, UHZ1, at aremarkableredshift ofZ=10.1.That puts UHZ1 far beyond Abell 2744,at a distance of 13.2 billion light-years, seen whenour universe was about 3 percent of its current age.UHZ1 is identified inthe insetsof this composited image combining X-rays (purple hues) from the spacebased Chandra X-ray Observatory andinfrared light from the James Webb Space Telescope.The X-ray emission from UHZ1 detected in the Chandra data isthe telltale signature of a growing supermassive black holeat the center of the ultra high redshift galaxy.

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 November 11 The SAR and the Milky Way Image Credit &Copyright:Julien Looten Explanation: This broad,luminous red arcwas a surprising visitor topartly cloudy evening skies over northern France.Captured extending toward the zenith in awest-to-east mosaicof images from November 5,the faint atmospheric ribbon of light isan example of a Stable Auroral Red (SAR) arc.The rarenight sky phenomenonwas also spotted atunusually low latitudes around world,along with more dynamic auroral displaysduring anintense geomagnetic storm.SAR arcs and their relation to auroral emission have beenexplored by citizen scienceandsatellite investigations.From altitudes substantially above the normal auroral glow,the deep red SAR emission is thought to be caused by strong heatingdue to currents flowing inplanet Earth's innermagnetosphere.Beyond this SAR, the Milky Way arcs above the cloud banksalong the horizon,a regular visitor to night skies over northern France.
