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. 2024 October 1 IFRAME: [2]https://www.youtube.com/embed/ExGvwNuKyMc?ref=0 Porphyrion: The Longest Known Black Hole Jets Animation Credit: [3]Science Communication Lab for [4]Martijn Oei [5]et al., [6]Caltech Explanation: How far can black hole jets extend? A [7]new record was found just recently with the discovery of a 23-million [8]light-year long jet pair from a black hole active billions of years ago. Dubbed [9]Porphyrion for a mythological Greek giant, the impressive jets were created by a type of [10]black hole that does not usually create long jets -- one that is busy creating radiation from infalling gas. The [11]featured animated video depicts what it might look like to circle around this powerful [12]black hole system. [13]Porphyrion is shown as a fast stream of [14]energetic particles, and the bright areas are where these particles are impacting surrounding gas. The discovery was made using data from the [15]Keck and [16]Mayall ([17]DESI) optical observatories as well as [18]LOFAR and the [19]Giant Metrewave Radio Telescope. The existence of [20]these jets demonstrates that black holes can affect not only their [21]home galaxies but [22]far out into the surrounding [23]universe.
