﻿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2023 August 2 [2]The spiral galaxy is shown with many complex red filaments extending out. Please see the explanation for more detailed information. M82: Galaxy with a Supergalactic Wind [3]NASA, [4]ESA, [5]Hubble; Processing & Copyright: [6]Harshwardhan Pathak Explanation: Why is the Cigar Galaxy billowing red smoke? [7]M82, as this [8]starburst galaxy is also known, was stirred up by a [9]recent pass near large [10]spiral galaxy [11]M81. This doesn't fully explain the source of the red-glowing outwardly [12]expanding gas and dust, however. [13]Evidence indicates that this gas and dust is being driven out by the combined emerging [14]particle winds of many stars, together creating a galactic [15]superwind. The dust particles are [16]thought to originate in M82's interstellar medium and are actually [17]similar in size to particles in cigar smoke. The [18]featured photographic mosaic highlights a [19]specific color of red light strongly emitted by ionized [20]hydrogen gas, showing detailed filaments of this gas and dust. The filaments extend for over 10,000 [21]light years. The 12-million light-year distant [22]Cigar Galaxy is the brightest galaxy in the sky in [23]infrared light and can be seen in visible light with a small [24]telescope [25]towards the [26]constellation of the Great Bear ([27]Ursa Major).
