Illuminate your space with the glowing beauty of this Emission Nebula Wall Art Print. Featuring the radiant clouds of ionized gas found in deep space, this artwork captures the vibrant reds, purples, and blues typical of active star-forming regions. A striking piece for space enthusiasts, science lovers, or anyone drawn to the mystery of the cosmos. Ideal for home offices, bedrooms, or gallery walls.

Sharpless 101: the Cosmic Tulip Sharpless 101 is a H II region emission nebula located in the constellation Cygnus. It is popularly called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless as Sh2-101 in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years from Earth. Sh2-101, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 belongs to a high-mass X-ray binary system, located about 6,070 light years from the Sun, that includes a blue supergiant variable star designated HDE 226868 which it orbits at about 0.2 AU, or 20% of the distance from the Earth to the Sun In the image below, red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the visible light emission from the Tulip Nebula. HDE 227018 is the bright star very near the blue arc at the center of the cosmic tulip. ► Image source>> https://apod.nasa.gov/apod/ap161020.html Image Credit & Copyright: Martin Pugh Further reading and references ► Cygnus (constellation)>> https://en.wikipedia.org/wiki/Cygnus_(constellation) ► OB associations>> https://en.wikipedia.org/wiki/Stellar_kinematics#OB_associations ► Cygnus X-1>> https://en.wikipedia.org/wiki/Cygnus_X-1 ► H II region>> https://en.wikipedia.org/wiki/H_II_region ► Sh2-101>> https://en.wikipedia.org/wiki/Sh2-101 ► Emission Nebula>> https://en.wikipedia.org/wiki/Emission_nebula #Universe, #TulipNebula, #CygnusConstellation, #EmissionNebula

O Catálogo de Messier é um conjunto de mais de 100 objetos astronômicos primeiro listada pelo astrônomo francês Charles Messier em 1771. Messier era um caçador de cometas que ficava frustrado por se confundir com objetos que não eram cometas, resolvendo então compilar uma lista deles com a colaboração de seu assistente Pierre Méchain, para evitar perder tempo com eles. O número de objetos do catálogo chegou a 103 durante sua vida, mas alguns mais atribuídos a Messier foram incluídos por outros astrônomos ao longo dos anos. O Catálogo de Messier inclui quase todos os tipos de de objetos de céu profundo - nebulosas difusas, nebulosas planetárias, aglomerados abertos, aglomerados globulares e galáxias. Uma vez que esse objetos podem ser reconhecidos visualmente, eles estão entre os objetos mais brilhantes e, portanto, mais atrativos observáveis mesmo a partir de grandes cidades. O objeto Messier de hoje é M 8, uma nebulosa de emissão, berçário de estrelas na constelação de Sagitário. The Messier Catalogue are a set of over 100 astronomical objects first listed by French astronomer Charles Messier in 1771. Messier was a comet hunter, and was frustrated by objects which resembled but were not comets, so he compiled a list of them, in collaboration with his assistant Pierre Méchain, to avoid wasting time on them. The number of objects in the catalog reached 103 during his lifetime but a few more thought to have been observed by Messier have been added by other astronomers over the years. The Messier catalogue comprises nearly all the most spectacular examples of the five types of deep sky object – diffuse nebulae, planetary nebulae, open clusters, globular clusters and galaxies. Since these objects can be observed visually, they are among the brightest and therefore most attractive observable even from large cities. Today's Messier object is M 8, an emission nebula and a starbirth site in the constellation of Sagittarius (the archer).

Here's a gorgeous image of what is known as #SoulNebula, #EmbryoNebula, or #IC1848. This #EmissionNebula is located 6,500 light years away from Earth. These areas were carved out by radiation and winds from the regions most massive stars. This is actually the best evidence for a theory called trigger star formation. It's when the carving of these cavities pushes gasses together to form / ignite stars. #astronomy #astrophotography #nebula
