This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA\u2019s Hubble Space Telescope<\/a>. The colors in Hubble\u2019s visible light image, which marks the 36th anniversary of the mission’s launch<\/a> on April 24, are reminiscent of an underwater scene filled with fine-grained sediments fluttering through the ocean\u2019s depths.<\/p>\n

Several massive stars, which are outside this field of view, have shaped this region for at least 300,000 years. (See them in a wider view.<\/a>) Their powerful winds continue to blow an enormous bubble, a small portion of which is shown here, that pushes and compresses the cloud\u2019s gas and dust, triggering new waves of star formation.<\/p>\n

NASA celebrates Hubble\u2019s 36th anniversary with a new image of the Trifid Nebula, a star-forming region it first captured in 1997. The telescope leveraged almost its full operational lifetime to show us changes in the nebula on human time scales with an improved camera.<\/p>\n

This isn\u2019t the first time Hubble has gazed at this scene. The telescope observed the Trifid in 1997<\/a> and now, 29 years later, it has leveraged almost its full operational lifetime to show us changes in the nebula<\/a> on human time scales. Why look at the same location again? In addition to seeing changes over time, Hubble is also equipped with an improved camera<\/a> with a wider field of view and greater sensitivity that was installed during Servicing Mission 4<\/a>.<\/p>\n

Hubble\u2019s view of the Trifid Nebula (also known as Messier 20 or M20<\/a>) focuses on a \u201chead\u201d and undulating \u201cbody\u201d of a rusty-colored cloud of gas and dust that resembles a marine sea lemon, or sea slug, that appears as if it is gliding through the cosmos.<\/p>\n

The Cosmic Sea Lemon\u2019s left \u201chorn\u201d is part of Herbig-Haro 399, a jet of plasma periodically ejected over centuries by a young protostar<\/a> embedded in the head of the sea lemon. Changes, as seen in the video below, allow researchers to measure the speeds of the outflows and determine how much energy the protostar is injecting into these regions. These measurements will provide insights into how newly formed stars interact with their surroundings.<\/p>\n

To the immediate lower right is evidence of the counter jet: jagged orange and red lines that \u201drun\u201d down the back of the sea lemon\u2019s neck, where a natural V appears in the brown dust.<\/p>\n

The darker, more triangular \u201chorn\u201d on the right of the \u201chead\u201d hosts another young star at its tip. Zoom in to see a faint red dot with a tiny jet. The green arc above it may be evidence that a circumstellar disk<\/a> is being eroded by the intense ultraviolet light from nearby massive stars. The clearer area around this protostar suggests it may almost be finished forming.<\/p>\n

To the immediate left of the Cosmic Sea Lemon is a small, faint pillar that resembles a water bear<\/a>. Much of this pillar\u2019s gas and dust has been blown away, but the densest material at the top persists.<\/p>\n

Streaks and sharp lines offer more clues about other young stars\u2019 activities. Spy an example by looking near the center for a rippling angled line that begins in a bright orange and ends in a blazing red. In the image comparison<\/a>, it appears to move, which means it may be a jet shot out by another actively forming star buried deeply in dust.<\/p>\n

NASA is celebrating the 36th anniversary of the Hubble Space Telescope with a stunning new look at the Trifid Nebula, a star-forming region about 5,000 light-years away.

In Hubble\u2019s visible light observations, the clearest view is toward the top left, where it\u2019s bluer. Strong ultraviolet light from massive stars, not in the field of view, stripped electrons from nearby gas, creating a glow, with winds sculpting a bubble by clearing out surrounding dust.<\/p>\n

At the top of the Cosmic Sea Lemon\u2019s head, bright yellow gas streams upward. This is an example of ultraviolet light plowing into the dark brown dust, stripping and dismantling the gas and dust.<\/p>\n

Many ridges and slopes of dark brown material will remain for a few million years, as the stars\u2019 ultraviolet light slowly eats away at the gas. The densest areas are home to protostars<\/a>, which are obscured in visible light.<\/p>\n

The far-right corner is nearly pitch black. This is where the dust is the densest. The stars that appear here may not be part of this star-forming region \u2014 they might be closer to us, in the foreground.<\/p>\n

Now, scan the scene for bright orange orbs. These stars have fully formed, clearing the space around them. Over millions of years, the nebula\u2019s gas and dust will disappear \u2014 only stars will remain.<\/p>\n

Hubble\u2019s varied instruments<\/a> and the expansive range of light it collects \u2014 from ultraviolet through visible to near-infrared \u2014 have helped researchers make ground-breaking discoveries<\/a> for decades and supply new data daily that will inevitably lead to more.<\/p>\n

The telescope has taken over 1.7 million observations to date. Almost 29,000 astronomers have published peer-reviewed science papers using Hubble data collected over the telescope\u2019s 36-year lifetime, resulting in more than 23,000 publications, with almost 1,100 in 2025 alone. Hubble\u2019s observational data is publicly available in the Barbara A. Mikulski Archive for Space Telescopes<\/a> at the Space Telescope Science Institute in Baltimore, while its mission descriptions, history, and gallery of popular images are found on\u00a0NASA\u2019s Hubble website<\/a>.<\/p>\n

Since 2022, researchers have regularly combined Hubble\u2019s observations with those from NASA’s James Webb Space Telescope<\/a> to push opportunities for discovery further. Very soon, astronomers will begin diving into huge near-infrared datasets from vast surveys from NASA’s new Nancy Grace Roman Space Telescope<\/a>, and will seek to compare them to existing or new Hubble observations to clarify what is at work. For context, Roman\u2019s camera can\u00a0cover the entire Trifid Nebula<\/a>, showing the full bubble, with a single pointing \u2014 and may turn up interesting objects for follow-up.<\/p>\n

Another flagship to look forward to? The mission concept known as the Habitable Worlds Observatory<\/a>, which would have a significantly larger mirror than Hubble \u2014 leading to higher resolution images \u2014 and, like Hubble, capture ultraviolet, visible, and infrared light. This next-generation space telescope would advance science across all of astrophysics, and would be the first specifically engineered telescope to identify habitable, Earth-like planets next to relatively bright stars like our Sun and examine them for evidence of life.<\/p>\n

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.<\/p>\n","protected":false},"excerpt":{"rendered":"This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured…\n","protected":false},"author":2,"featured_media":408490,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[909,1505,163820,1507,1508,61,60,15742,82,247,3212,1510],"class_list":{"0":"post-408489","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-astrophysics","9":"tag-astrophysics-division","10":"tag-emission-nebulae","11":"tag-goddard-space-flight-center","12":"tag-hubble-space-telescope","13":"tag-ie","14":"tag-ireland","15":"tag-nebulae","16":"tag-science","17":"tag-space","18":"tag-stars","19":"tag-the-universe"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/408489","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=408489"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/408489\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/408490"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=408489"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=408489"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=408489"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
