🔭 NGC 6888: The Crescent Nebula

Image Credit & Copyright: Greg Bass

apod.nasa.gov/apod/ap25112...
NGC 6888, also known as the Crescent Nebula, is a about 25 light-years across, a cosmic bubble blown by winds from its central, massive star. This deep telescopic image includes narrowband image data, to isolate light from hydrogen and oxygen atoms. The oxygen atoms produce the blue-green hue that seems to enshroud the nebula's detailed folds and filaments. Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. In fact, the Crescent Nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life, this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

🔭 Portrait of NGC 1055

Image Credit & Copyright: John Hayes

apod.nasa.gov/apod/ap25112...
Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But telltale pinkish star forming regions and young blue star clusters are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bulge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.

🔭 3I/ATLAS: A View from Planet Earth

Image Credit & Copyright: Rolando Ligustri

apod.nasa.gov/apod/ap25112...
Now outbound after its perihelion or closest approach to the Sun on October 29, Comet 3I/ATLAS is only the third known interstellar object to pass through our fair Solar System. Its greenish coma and faint tails are seen against a background of stars in the constellation Virgo in this view from planet Earth, recorded with a small telescope on November 14. But this interstellar interloper is the subject of an on-going, unprecedented Solar System-wide observing campaign involving spacecraft and space telescopes from Earth orbit to the surface of Mars and beyond. And while the comet from another star-system has recently grown brighter, you'll still need a telescope if you want to see 3I/ATLAS from planet Earth. It's now above the horizon in November morning skies and will make its closest approach to Earth, a comfortable 270 million kilometers distant, around December 19.

🔭 Alnitak, Alnilam, Mintaka

Image Credit & Copyright: Aygen Erkaslan

apod.nasa.gov/apod/ap25112...
Alnitak, Alnilam, and Mintaka are the bright bluish stars from east to west (upper right to lower left) along the diagonal in this cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie from 700 to 2,000 light-years away, born of Orion's well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have some surprisingly familiar shapes, including the dark Horsehead Nebula and Flame Nebula near Alnitak at the upper right. The famous Orion Nebula itself is off the right edge of this colorful starfield. The telescopic frame spans almost 4 degrees on the sky.

En la @bonilista conté por qué QA no va de “hacer pruebas” sino de impacto en negocio.
La IA democratiza el testing y el valor se mueve a orquestar sistemas de calidad.

🔭 Orion and the Running Man

Image Credit & Copyright: R. Jay Gabany

star.ucl.ac.uk/~apod/apod/a...
Few cosmic vistas can excite the imagination like The Great Nebula in Orion. Visible as a faint, bland celestial smudge to the naked eye, the nearest large star-forming region sprawls across this sharp colourful telescopic image. Designated M42 in the Messier Catalogue, the Orion Nebula's glowing gas and dust surrounds hot, young stars. About 40 light-years across, M42 is at the edge of an immense interstellar molecular cloud only 1,500 light-years away that lies within the same spiral arm of our Milky Way galaxy as the Sun. Including dusty bluish reflection nebula NGC 1977, also known as the Running Man nebula at left in the frame, the natal nebulae represent only a small fraction of our galactic neighbourhood's wealth of star-forming material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems.

🔭 Andromeda and Friends

Image Credit & Copyright: Piotr Czerski

apod.nasa.gov/apod/ap25111...
This magnificent extragalactic skyscape looks toward the Andromeda Galaxy, the closest large spiral galaxy to the Milky Way. It also accomplishes a Messier catalog trifecta by including Andromeda, cataloged as Messier 31 (M31), along with Messier 32 (M32), and Messier 110 (M110) in the same telescopic field of view. In this frame, M32 is just left of the Andromeda Galaxy's bright core with M110 below and to the right. M32 and M110 are both elliptical galaxies themselves and satellites of the larger spiral Andromeda. By combining 60 hours of broadband and narrowband image data, the deep telescopic view also reveals tantalizing details of dust lanes, young star clusters, and star-forming regions along Andromeda's spiral arms, and faint, foreground clouds of glowing hydrogen gas. For now, Andromeda and friends are some 2.5 million light-years from our own large spiral Milky Way.

🔭 Florida Northern Lights

Image Credit & Copyright: Samil Cabrera

star.ucl.ac.uk/~apod/apod/a...
Northern lights have come to Florida skies. In fact, the brilliant streak of a Northern Taurid meteor flashes through the starry night sky above the beach in this sea and skyscape, captured from Shired Island, Florida on November 11. Meteors from the annual Northern Taurid meteor shower are expected this time of year. But the digital camera exposure also records the shimmering glow of aurora, a phenomenon more often seen from our fair planet's higher geographical latitudes. Also known as aurora borealis, these northern lights are part of recent, wide spread auroral activity caused by strong geomagnetic storms. In the last few days, stormy spaceweather has been triggered by multiple Earth impacting coronal mass ejections and intense solar activity.
