Melotte 15, Within the Heart

[wonders-of-the-cosmos]

Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia.

Explanation: What excites the Heart Nebula? First, the large emission nebula on the upper left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by sulfur (yellow) and oxygen (blue). In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their atom-exciting energetic light and winds. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. This wide field image shows much more, though, including the Fishhead Nebula just below the Heart, a supernova remnant on the lower left, and three planetary nebulas on the image right. Taken over 57 nights, this image is so deep, though, that it clearly shows fainter long and complex filaments.

The Heart Nebula Talon Abraxas

The Heart Nebula is an emission nebula located in the constellation of Cassiopeia, around 7,500 light years away from Earth. It has an apparent magnitude of 18.3 and an absolute magnitude of 6.5. Sometimes, it is known as the Running Dog Nebula because, when seen through a telescope, it looks a bit like a running dog.

The nebula was given its name the Heart Nebula because of its intensely red glowing gas and dark dust lanes that form a shape that resembles a heart symbol. It forms a famous complex known as the Heart and Soul with its smaller neighbour Westerhout 5, also known as the Soul Nebula, which lies just 2.5 degrees to the southeast.

The Heart Nebula is around 150 arcminutes in size and has been given the designation of Sharpless 2-190 in the Sharpless Catalogue, as well as IC 1805. The brightest part of the Heart Nebula has the designation NGC 896 in the New General Catalogue. It is classified separately because it was the first part of IC 1805 to be discovered.

The glow of the nebula comes from the radiation of a small open cluster of stars known as Melotte 15. The cluster contains very young, blue, hot supergiant stars that are about 1.5 million years old and is located near the nebula’s centre.

The Heart Nebula on the right (IC 1805, Sharpless 2-190) and Soul Nebula, left, (Westerhout 5 with the star cluster IC 1848) in Hydrogen-alpha. These two make up a massive star-forming complex in Cassiopeia about 7500 lightyears away in the Perseus Arm of our Galaxy. The bright emission nebula on the far right is the Fishhead Nebula (NGC 896, IC 1795). The small circular cloud, middle top, is another emission nebula Sh2-198, much further away, around 18,000 lightyears (still, well within the galaxy). The bright cluster of stars in the core of the Heart Nebula is Melotte 15.

Rural Employment Improves but Lags Recession-Era Jobs

by Sarah Melotte, The Daily YonderJune 10, 2024 Rural America added 171,200 jobs last year but still hasn’t recovered the employment it lost during the pandemic. For that matter, it hasn’t replaced the jobs lost during the Great Recession 15 years ago. According to a Daily Yonder analysis of new data from the Bureau of Labor Statistics, the number of jobs in rural (nonmetropolitan) counties…

Explanation: Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are scattered in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 15 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - the Heart Nebula. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia.

The Heart Nebula. This large emission nebula dubbed IC 1805 looks, in whole, like a human heart. This heart glows brightly in red light emitted by its most prominent element: hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the heart of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of the mythological Queen of Aethiopia (Cassiopeia).

Explanation: What excites the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. Its shape perhaps fitting of the Valentine's Day, this heart glows brightly in red light emitted by its most prominent element: excited hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the heart of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds.

The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by silicon (yellow) and oxygen (blue).

This wide and deep image clearly shows, though, that glowing gas surrounds the Heart Nebula in all directions. © William Ostling, Telescope Live
