La Espectacular Galaxia de Andrómeda 💫

El objeto más distante fácilmente visible a simple vista es M31, la gran Galaxia de Andrómeda. Incluso a unos dos millones y medio de años luz de distancia, esta inmensa galaxia espiral, que abarca más de 200.000 años luz, es visible, aunque como una tenue nube nebulosa en la constelación de Andrómeda.

En contraste, un núcleo amarillo brillante, oscuras y sinuosas franjas de polvo y brazos espirales expansivos salpicados de cúmulos de estrellas azules y nebulosas rojas, se registran en esta impresionante imagen telescópica que combina datos del Hubble en órbita con imágenes terrestres de los telescopios Subaru y Mayall.

En solo unos 5 mil millones de años, la galaxia de Andrómeda puede ser incluso más fácil de ver, ya que probablemente abarcará todo el cielo nocturno, justo antes de fusionarse con nuestra Vía Láctea.

Shell Galaxies in Pisces (APOD: 2024 Nov 07)

Explanation: This spectacular intergalactic skyscape features Arp 227, a curious system of galaxies from the 1966 Atlas of Peculiar Galaxies. Some 100 million light-years distant within the boundaries of the constellation Pisces, Arp 227 consists of the two galaxies prominent above and left of center, the shell galaxy NGC 474 and its blue, spiral-armed neighbor NGC 470. The readily apparent shells and star streams of NGC 474 are likely tidal features originating from the accretion of another smaller galaxy during close gravitational encounters that began over a billion years ago. The large galaxy on the bottom righthand side of the deep image, NGC 467, appears to be surrounded by faint shells and streams too, evidence of another merging galaxy system. Intriguing background galaxies are scattered around the field that also includes spiky foreground stars. Of course, those stars lie well within our own Milky Way Galaxy. The telescopic field of view spans 25 arc minutes or just under 1/2 degree on the sky.

Spanning across 25 light-years, the Crescent Nebula, NGC 6888, is a vibrant display of gas that was ejected from the Wolf-Rayet star, WR 136, at its center.

The photo was captured by Francesco-di Biase in Puglia, Italy, on July 22, 2023. He used an 12-inch Ritchey–Chrétien telescope, a Moravian Instruments G2-4000 camera, Astrodon narrowband filters, and a 10 Micron Astrotechnology GM2000 HPS II Monolith mount.

This Hubble image shows two galaxies colliding. The larger galaxy on the left is a Seyfert galaxy, which is notable because, despite the immense brightness of its core, radiation from the entire galaxy is observable.

“The universe is not outside of you. Look inside yourself—everything that you want, you already are.” —Rumi

Today is , celebrating 13th century poet Jalal al-Din Rumi. The Boomerang, an hourglass-shaped reflection nebula formed by material ejected by its central star, provides inspiration for reflection on ourselves and our place in the universe.
