@gazingoutwards This is a deep view of M27, the Dumbbell Nebula. About 1,000 lightyears away, it's a preview of the fate that we believe is in the future for our own sun as it sheds its outer layers in undulating waves of gasses that will then be ionized and glow as these do. At least it will be beautiful for our cosmic neighbors 6 billion years from now when ours goes. :)
The James Webb Space Telescope has delivered a spectacular and unprecedented view of a star-forming region known as the Tarantula Nebula.
.
The superb new detail in the image means Doradus 30, initially nicknamed Tarantula for its spider-like appearance, can now be seen to also resemble a burrowing tarantula's lair, lined with silk.
.
The Tarantula Nebula is located 161,000 light-years away in the Large Magellanic Cloud and is the brightest star-forming region in the galaxies nearest to our Milky Way, collectively known as the Local Group.
.
In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of never-before-seen young stars that were previously shrouded in cosmic dust.

This image from the James Webb Space Telescope shows the heart of M74, otherwise known as the Phantom Galaxy. Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the centre of this image. A lack of gas in the nuclear region also provides an unobscured view of the nuclear star cluster at the galaxy's centre. M74 is a particular class of spiral galaxy known as a ‘grand design spiral’, meaning that its spiral arms are prominent and well-defined, unlike the patchy and ragged structure seen in some spiral galaxies.
The Phantom Galaxy is around 32 million light-years away from Earth in the constellation Pisces, and lies almost face-on to Earth. This, coupled with its well-defined spiral arms, makes it a favourite target for astronomers studying the origin and structure of galactic spirals.
Webb gazed into M74 with its Mid-InfraRed Instrument (MIRI) in order to learn more about the earliest phases of star formation in the local Universe. These observations are part of a larger effort to chart 19 nearby star-forming galaxies in the infrared by the international PHANGS collaboration. Those galaxies have already been observed using the Hubble Space Telescope and ground-based observatories. The addition of crystal-clear Webb observations at longer wavelengths will allow astronomers to pinpoint star-forming regions in the galaxies, accurately measure the masses and ages of star clusters, and gain insights into the nature of the small grains of dust drifting in interstellar space.

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.
WR 134 was one of three stars in Cygnus observed in 1867 to have unusual spectra consisting of intense emission lines rather than the more normal continuum and absorption lines. These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after Charles Wolf and Georges Rayet who discovered their unusual appearance

@_ethereal_astro Known by many names and one of the largest star-forming regions in the Milky Way galaxy: M17, Omega, Horseshoe, Checkmark, Swan and in the southern hemisphere, Lobster. This nebula is a vast interstellar cloud of dust and gas giving birth to our galaxy’s youngest star clusters, at only 1 million years old. Many of the young stars in this cluster are impossible to see however because of the gas and dust that surrounds them; with some pockets measuring ten times larger than our solar system. Spanning some 15 light-years in diameter and found in the Sagittarius Arm of the hazy starlit band of our Milky Way and easily visible with a pair of binoculars, you’ll be gazing at deep-sky wonders in the next spiral arm inward toward the direction of the star-rich center of our Milky Way galaxy. The Omega Nebula geometry is similar to its winter cousin, The Orion Nebula; except that the Omega Nebula is viewed edge-on, rather than face-on. This image as viewed spans 3 degrees of the Southern sky.
