Stunning ultra-detailed picture of Sculptor galaxy unveiled by ESO
Astronomers at the
European Southern Observatory
(ESO) have unveiled the most stunning and
ultra-detailed map
ever created of the
Sculptor galaxy
, also known as
NGC 253
. Located about 11 million light years away, this galaxy shares many similarities with our own Milky Way in terms of size and structure. Using the powerful
Multi Unit Spectroscopic Explorer
(MUSE) instrument on ESO's
Very Large Telescope
, researchers spent over 50 hours capturing more than 100 exposures. The resulting image covers an area 65,000 light years wide and reveals thousands of colors, offering unprecedented insight into the stars, gas, and dust within the galaxy.
Sculptor galaxy in unmatched details
The Sculptor galaxy is close enough for astronomers to resolve its internal structure with incredible precision while still observing it as a whole system. This ultra-detailed map allows scientists to study the galaxy's building blocks—stars, gas, and dust—in ways never before possible. Unlike typical galaxy images that show only a few colors, this image reveals thousands, providing vital information about the age, composition, and motion of celestial objects within Sculptor.

To create this breathtaking map, researchers used ESO's Multi Unit Spectroscopic Explorer (MUSE) instrument on the Very Large Telescope in Chile. They observed the Sculptor galaxy for over 50 hours and stitched together more than 100 exposures. The final image spans an area 65,000 light years wide, capturing a vast and detailed view of the galaxy's structure and composition.
New discoveries: Planetary nebulae and star formation
The detailed image has already led to the discovery of 500 new planetary nebulae—shells of gas and dust emitted by dying stars. These nebulae help astronomers verify the distance to the Sculptor galaxy, which is crucial for further studies. The map also allows researchers to examine how gas flows and changes composition to form new stars, shedding light on the life cycle of galaxies.
Why Sculptor galaxy matters
Like our neighboring Andromeda galaxy, the Sculptor galaxy is bright, large, and easily visible with binoculars under ideal conditions. Its proximity and size make it an excellent subject for studying galactic evolution. This new ultra-detailed map marks a significant step forward in understanding how galaxies like our own Milky Way form, evolve, and sustain star formation.
Looking ahead: Future research opportunities
With this detailed map in hand, astronomers plan to delve deeper into the Sculptor galaxy's dynamics. They aim to study gas flows, star formation processes, and the lifecycle of stars with unprecedented clarity. This breakthrough will not only enhance our knowledge of Sculptor but also provide valuable insights applicable to other galaxies across the universe.

UK eyes more high skilled Indian professionals through Global Talent visa
The United Kingdom is looking to deepen its scientific and academic relationship with India by inviting more high-skilled professionals through its Global Talent visa scheme, British Science Minister Lord Patrick Vallance said on June 20, while speaking at the 'Unlocking UK-India Collaboration for a New Era of Innovation' session at the India Global Forum in London, Vallance said India's growing strength in science and technology offers strong potential for bilateral cooperation. 'There is already a strong relationship between India and the UK, and I think it's growing,' Vallance said. 'But government-to-government relationships on science aren't actually what drives everything. It has to be a scientist and a scientist as well.' The UK government plans to announce a new Industrial Strategy in the coming weeks, which will outline key international partnerships, including India, with a focus on science, innovation, and skilled mobility. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like These Companies Are Overcharging You For Florida Auto Insurance Smart Lifestyle Trends Learn More Undo Global talent visa in focus (Join our ETNRI WhatsApp channel for all the latest updates) The UK's Global Talent visa aims to attract top-tier individuals from around the world who have demonstrated leadership—or the potential for it—in academia, research, arts, culture, or technology.

Candidates can apply for the visa through the UK Home Office . The endorsement stage generally takes 4 to 8 weeks for a decision. After receiving endorsement, applicants must submit a visa application to UK Visas and Immigration (UKVI). The standard visa processing time is around 3 weeks when applying from outside the UK. Applicants are required to pay an endorsement fee of £524 and a visa application fee of £192. Additionally, the immigration health surcharge is £624 per year. The visa is typically granted for up to 5 years and is extendable, with eligibility for permanent settlement after 3 to 5 years depending on the endorsement type. To bring flexibility and international expertise into the UK, the visa supports long-term settlement: individuals recognised as established leaders may qualify for indefinite leave after three years, while those with emerging promise have a five-year path to settlement. Family members can also be included in this program.

5 animals that could gulp a human in one go
While saltwater crocodiles and Komodo dragons could potentially swallow a small human in pieces or whole, humpback whales lack the physical ability. Reticulated pythons have been confirmed to swallow humans entirely, as evidenced by a 2017 incident in Indonesia. Although unconfirmed, green anacondas possess the capability to consume a human, given their size and prey. Human beings have always been considered as apex predators in the food pyramid, but even the idea of being swallowed by a giant beast like an anaconda is no less than a nightmare and seems to be a story out of tabloid headlines and survival horror stories. But how likely is it in real life? While most animals, even large ones, prefer to tear food into manageable pieces, there are a few exceptions that make the possibility more real than we'd like to believe. Some creatures have the size, anatomy, and appetite to at least try it! Be it massive reptiles to mysterious ocean giants, the animal kingdom includes a handful of contenders capable of swallowing something about human-sized. The odds are low, but not zero. Here are five animals that are capable enough to swallow a human being Saltwater crocodile Saltwater crocodiles are the largest living reptiles, with some males reaching as long as 6 metres and a tonne in weight. However, they don't swallow their prey whole. Instead, they perform a 'death roll' to tear limbs from the body, then swallow in pieces. While it's rare, a very small human might disappear in a few gulps, though this is mostly speculative. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Scam Exposed: What They Won't Tell You about zero trust! Expertinspector Click Here Undo Komodo dragon Komodo dragons are the world's largest lizards, growing up to 3 metres and weighing up to 100kg. These Indonesian predators use serrated, iron-tipped teeth to shred flesh in violent bites. Larger prey is torn into chunks, but animals the size of young goats have been swallowed whole. According to the Komodo National Park, human attacks are documented, 24 between 1974 and 2012, five fatal, but no confirmed cases of a person being swallowed exist. Still, a small adult or child could be within range of this possibility. Humpback whale Despite their massive size, humpback whales can't swallow a human. Their throats are too narrow, adapted only for small prey like krill and fish. In 2021, lobster diver Michael Packard was briefly engulfed by a feeding humpback off Massachusetts, but was spat out after 30 seconds, as reported by BBC. There were no injuries, just shock and confusion. Humpbacks don't target humans, and this rare encounter was more about bad luck than danger. Reticulated python The reticulated python is the only animal on this list proven to have swallowed humans whole. Native to Southeast Asia, it can grow over 7 metres long and kills prey by constriction before swallowing it entirely. Its flexible jaw and expandable body allow it to ingest creatures far wider than itself. Deutsche Welle reported that on March 29, 2017, villagers in Sulawesi, Indonesia, discovered the missing farmer Akbar inside a 7 m python after noticing the snake moving awkwardly. They cut it open and retrieved his fully intact body. Green anaconda Green anacondas, found in South America, may not be as long as pythons but are much heavier, sometimes growing to be as heavy as 100kg. They've been known to kill large animals like caimans and capybaras. Human consumption has never been confirmed, likely due to the snake's reclusive habitat. However, a 2024 video showed a man nearly crushed by one in a Brazilian river before escaping with help. While no verified cases of human swallowing exist, the potential is definitely there under the right or wrong circumstances. Photo credits: Canva
