Enter the Dragon 🐉🥋Here it is – my new JWST image of the young protostellar outflow system in Cassiopeia called HH288, aka The Dragon Jet.We discovered it in the 1990s & the NASA/ESA/CSA JWST reveals stunning new detail, including several new jets crossing the main dragon 🙂👍This is a 4K version – you can view & download the full 12K image here: <a href="https://www.flickr.com/gp/markmccaughrean/944q5814f8" rel="nofollow" class="ellipsis" title="www.flickr.com/gp/markmccaughrean/944q5814f8">https://www.flickr.com/gp/markmccaughrean/944q5814f8</a>For more coverage, see this by <a href="https://mastodon.social/@DrCarpineti" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@DrCarpineti</a> at: <a href="https://www.iflscience.com/dragon-jet-erupts-from-baby-stars-in-stunning-new-jwst-image-82374" rel="nofollow" class="ellipsis" title="www.iflscience.com/dragon-jet-erupts-from-baby-stars-in-stunning-new-jwst-image-82374">https://www.iflscience.com/dragon-jet-erupts-from-baby-stars-in-stunning-new-jwst-image-82374</a><a href="/tags/space/" rel="tag">#Space</a> <a href="/tags/spacescience/" rel="tag">#SpaceScience</a> <a href="/tags/astronomy/" rel="tag">#Astronomy</a> <a href="/tags/photography/" rel="tag">#Photography</a>

An image of a young protostellar outflow called HH288 in space, as seen with JWST. Much of the background is dark black and blue, with many stars sprinkled across with different colours and brightnesses, many showing the classic eight-pointed shape that comes from the JWST optics. The Dragon Jet itself is a swath of red, orange, and yellow emission spread horizontally across the image, with at least two crossing flows. The main flow resembles a Chinese dragon, hence the name.

The young crescent moon occulted Mercury today...as seen from the mountains of southern New Mexico.First photo is a telephoto shot of the moon only a minute after it uncovered our innermost planet. This was taken in bright twilight as a wind and dust storm was easing up.Second photo is a wider angle shot ten minutes later that includes Venus in the bottom third of the frame. The evening twilight sky colors are pallid because of the dust storm clouds billowing a mile below me on the floor of the Tularosa basin.<a href="/tags/mercury/" rel="tag">#Mercury</a> <a href="/tags/moon/" rel="tag">#Moon</a> <a href="/tags/crescent/" rel="tag">#Crescent</a> <a href="/tags/occult/" rel="tag">#Occult</a> <a href="/tags/occultation/" rel="tag">#Occultation</a> <a href="/tags/astronomy/" rel="tag">#Astronomy</a> <a href="/tags/twilight/" rel="tag">#Twilight</a> <a href="/tags/evening/" rel="tag">#Evening</a> <a href="/tags/photography/" rel="tag">#Photography</a> <a href="/tags/astrophotography/" rel="tag">#Astrophotography</a>

The twilight sky is a medium blue while the crescent moon is a bright gray. Mercury is the overexposed white dot near the left horn of the crescent moon. Some crater and terrain detail is visible on the moon. Twilight is still so bright that we can't yet see earthshine on the rest of the moon's disk.

The evening twilight sky as a dust storm is easing up. The colors are subdued and the nearby trees are blurred in the exposure as they whip back and forth in the strong wind. Venus is visible below the crescent moon, about 1/3 of the way up from the very bottom of the frame. Mercury is visible next to the crescent moon.

JWST NIRCam and MIRI image of Arp 142, also known as NGC 2936, NGC 2937, and UGC 5130, or the Penguin and the Egg.The Penguin is a spiral galaxy whose shape has been distorted by the gravity of the elliptical Egg galaxy. The two are about 100,000 light-years apart and completed a close pass between 25 and 75 million years ago.Credit: NASA, ESA, CSA, STScI Source: <a href="https://webbtelescope.org/contents/media/images/2024/124/01J06XYGEDEE86D1H9N5EJ9EG0" rel="nofollow" class="ellipsis" title="webbtelescope.org/contents/media/images/2024/124/01J06XYGEDEE86D1H9N5EJ9EG0">https://webbtelescope.org/contents/media/images/2024/124/01J06XYGEDEE86D1H9N5EJ9EG0</a><a href="/tags/arpgalaxy/" rel="tag">#ArpGalaxy</a> <a href="/tags/galaxy/" rel="tag">#Galaxy</a> <a href="/tags/space/" rel="tag">#Space</a> <a href="/tags/astronomy/" rel="tag">#Astronomy</a> <a href="/tags/jwst/" rel="tag">#JWST</a>

$Arp 142, two interacting galaxies, observed in near- and mid-infrared light. At left is NGC 2937, nicknamed the Egg. Its center is brighter and whiter. There are six diffraction spikes atop its gauzy blue layers. At right is NGC 2936, nicknamed the Penguin. Its beak-like region points toward and above the Egg. Where the eye would be is a small, opaque yellow spiral. The Penguin’s distorted arms and orange dust lanes from the bird’s beak, back, and tail. The tail is wide and layered, like a beta fish’s tail. A semi-transparent blue hue traces the Penguin and extends from the galaxy, creating an upside-down U over top of both galaxies. At top right is another galaxy seen from the side, pointing roughly at a 45-degree angle. It is largely light blue. Its length appears approximately as long as the Egg’s height. One foreground star with large, bright blue diffraction spikes appears over top of the galaxy and another near it. The entire black background is filled with tiny, extremely distant galaxies.$
