The
Hubble Space Telescope
has released a breathtaking new view of the iconic
Sombrero Galaxy
(Messier 104) to mark its 35th anniversary. This stunning picture unveils subtle details of the galaxy's architecture, presenting a new angle on one of the universe's most recognised galaxies. This latest release marks decades of space discovery and our growing understanding of this mysterious cosmic marvel. The sophisticated nuances of the image emphasise the galaxy's unique shape, such as its shining central bulge and dusty disc surrounding it, providing scholars and hobbyists with a more vivid glimpse of this celestial monument.
NASA's Hubble turns 35 with a stunning hat-like structure image of the Sombrero Galaxy
According to NASA, 30 million light-years away in the Virgo constellation, the Sombrero Galaxy is one of the most stunning galaxies to be seen from Earth. Its resemblance is instantaneous—a brilliant bulge in the center surrounded by a defined dusty disc, evoking the image of a Mexican sombrero hat. That distinctive look is what has made it aptly known as the "Sombrero Galaxy."
The central bulge of the galaxy is densely packed with stars, and the disk is crowded with faint dust lanes, which give the striking shape. The image of the Sombrero Galaxy has fascinated astronomers and stargazers for decades with its breathtaking beauty.

Hubble's new image unveils richer details of the Sombrero Galaxy
This new Hubble photo of the Sombrero Galaxy showcases the advanced processing techniques that bring out more detailed information not apparent in earlier observations. Employing these techniques, astronomers were able to expose not only the galaxy's disc but also distant background stars and other faraway galaxies. The final product is a much richer and more detailed image of the Sombrero Galaxy than ever before.
Since the galaxy is larger than the Hubble Space Telescope's finite field of view, the new image is actually a mosaic, sewn together from several observations. That way, scientists can digest the whole scale of the structure of the galaxy at high resolution, something they can't do with one image.
Sombrero Galaxy's tilt reveals stunning dust lanes and central bulge
The Sombrero Galaxy is only six degrees tilted from its equator, providing us with an almost edge-on perspective from Earth as per NASA reports. The tilt provides a breathtaking shape, with fine clumps and streams of dust set against the galaxy's white shining core. This eyepiece sight is similar to that of Saturn's ring but much, much larger in proportion and galaxy size. The bright central bulge and dust lanes produce an extremely sharp contrast which has rendered the galaxy a top choice for both amateur and professional astronomers.
The nearly edge-on perspective is something that happens very rarely and enables one to glimpse the intricate structure of a galaxy. It has been of great fascination to astronomers over the past few decades because it provides insight into how galaxies change over a period of millions of years.
Sombrero Galaxy's calm star formation despite a massive black hole
The Sombrero Galaxy has a
supermassive black hole
at its centre weighing approximately nine billion solar masses, greater than 2,000 times as massive as the central Milky Way's black hole. But the galaxy is surprisingly calm with regard to star birth. It produces less than one solar mass of new stars per year, a relatively modest number compared to other galaxies of its size.
This quiet star formation lends mystery to the galaxy. Although it shows signs of spiral and elliptical galaxies, it does not have the robust star formation that would be found in a galaxy as large and dense as this one. This slow rate of new star formation has left researchers perplexed, who continue watching the unusual behaviour of the galaxy.
Sombrero Galaxy
Apart from Hubble observations, the Sombrero Galaxy has also been thoroughly investigated by other space telescopes such as the James Webb Space Telescope. At the end of 2024, Webb offered further infrared observations, which offered further insights into the structure and activity of the galaxy. Such discoveries will enable astronomers to further understand how galaxies such as the Sombrero develop, age, and behave over their lifespan.
Webb's infrared is especially good at seeing dust and gas that is not necessarily brought into visible light. Combining data from Webb and Hubble, astronomers can learn more about the Sombrero Galaxy.

Hundreds of statues found at 2,700-year-old Greek temple in Cyprus
Image: Department of Antiquities Cyprus Archaeologists have uncovered a magnificent ancient temple in a quiet valley in Cyprus where hundreds of statues dedicated to the Greek god Apollo have been found. The site dates back nearly 2,700 years and offers a rare look into the rituals and beliefs of early worshippers. A team of German researchers led the excavation and described the discovery as spectacular. Among the artefacts were towering statues, fine glass beads and even Egyptian amulets. The finds offer new clues about Cyprus's ancient past and the sacred spaces once built to honour gods like Apollo. How scientists discovered hundreds of statues in Cyprus The Sanctuary of Apollo was first found in 1885 by a German archaeologist named Max Ohnefalsch-Richter. He carried out a brief and incomplete dig before covering the site back up. For more than a hundred years the exact location was lost. Then in 2021 a new team of German archaeologists returned to the area and found it once again. They began a proper excavation and soon came across parts of statues and other remains that had been missed the first time. Artefacts found from the ancient temple What they found was extraordinary. There were hundreds of offerings made to Apollo, including statues both small and massive. Some were familiar and already housed in museums. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch vàng CFDs với mức chênh lệch giá thấp nhất IC Markets Đăng ký Undo But new fragments allow these pieces to be fully restored. Other objects were entirely new such as marble-like beads and decorative items from Egypt. One striking find was a pair of huge limestone feet suggesting that statues even larger than life once stood there. New discoveries change what we know so far The team also found statue types never seen before at this site. These included larger male figures made of limestone which were only known in terracotta form until now. The famous Colossus of Tamassos thought to be one of a kind may now be part of a wider tradition of grand sculptures made for this sanctuary. These findings show that the site was more complex and important than experts had believed. Ancient writing links to Egyptian rulers Among the most important discoveries were two statue bases with inscriptions. One used a local Cypriot script while the other had Greek writing mentioning the Ptolemies who ruled Egypt and also controlled Cyprus during that time. These inscriptions help date the site to the 6th and 7th centuries BC and show that the temple stayed in use for a long time. Rewriting Cyprus's ancient past The discoveries have opened a new chapter in the story of ancient Cyprus. Experts from the Cyprus Department of Antiquities say the finds have changed what we know about the island's religious history. Many broken statues can now be pieced together and put on display. Others are being studied to understand how people worshiped and what they believed. After lying hidden for more than a century the Sanctuary of Apollo is once again revealing its secrets.

Strange radio waves detected beneath Antarctica's ice, scientists still searching for the source
A team of researchers working in Antarctica has detected unusual radio signals emerging from deep beneath the ice. These waves were picked up during an experiment using the Antarctic Impulsive Transient Antenna (ANITA), a NASA-funded project that searches for high-energy particles from space. Tired of too many ads? go ad free now The discovery was unexpected as the signals appeared to be coming from below the surface rather than from space. Scientists say the waves are unlikely to be caused by known particles like neutrinos and have yet to determine exactly what is producing them. Radio waves found during neutrino search in Antarctica The ANITA experiment was designed to study high-energy neutrinos using a balloon that carried radio instruments into the stratosphere. Antarctica was chosen as the site due to its isolation and low interference from other radio sources. While searching for neutrinos researchers came across signals coming from around 30 degrees below the ice surface. These signals were unexpected because they would have had to pass through thousands of kilometres of rock which should have absorbed them completely. Neutrinos ruled out as the cause Stephanie Wissel, an astrophysicist at Penn State University and part of the ANITA team, explained that the signals were not consistent with neutrinos. Neutrinos are incredibly difficult to detect and rarely interact with matter. Although they can travel great distances through solid rock the angles and nature of the signals did not match what scientists expect from neutrino interactions. The team also cross-checked their findings with data from two other experiments and found no matches confirming that these were not neutrino events. Theories and unanswered questions around the mystery Since neutrinos were ruled out scientists are now considering other explanations. Tired of too many ads? go ad free now Some have proposed the signals could be related to dark matter or unknown radio wave behaviour around the ice and the horizon. However none of these theories have been confirmed. Wissel said that while they have explored several ideas none fully explain what was detected. She added that more experiments and data will be needed to understand what is happening under the Antarctic ice. Search continues for the mysterious source The instruments used in the experiment were lifted about 40 kilometres into the sky to capture faint radio emissions. While this approach allows for a broad view of signals entering Earth from space it also reveals unexpected activity from below. As scientists continue to review the data and prepare for future missions they hope to uncover more about the nature of these strange signals. For now the source of the radio waves remains a mystery.

Over 100 marine megafauna struggle for survival, despite global protections
Source: The oceans are home to iconic marine megafauna , including majestic whales, ancient turtles, agile seals, and powerful sharks. These incredible water creatures sit at the very top of the ocean food webs, playing a crucial role in maintaining balanced and healthy marine ecosystems. But now, over 100 marine megafaunal species are facing mounting threats as increasing human pressure dramatically reshapes their home—the vast and fragile ocean environment. According to recent research conducted by the Woods Hole Oceanographic Institution (WHOI) and the Australian National University (ANU) has carefully tracked the movements of these megafaunal species throughout the oceans to pinpoint the most important areas that require urgent and focused conservation efforts. About marine megafaunal species Marine megafauna are the giants of the ocean—large animals like whales, dolphins, sharks, sea turtles, and giant rays. These creatures aren't just beautiful and captivating; they're essential. They play critical roles in maintaining the health of marine ecosystems. Their presence supports biodiversity and helps oceans function as stable, resilient ecosystems. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Fastest Selling Plots of Mysore from 40L | 40+ Amenities PurpleBrick Learn More Undo Sea creatures like whales help circulate nutrients by diving deep and then surfacing to breathe, effectively stirring the ocean layers. Sea turtles keep seagrass beds healthy by grazing. Despite their importance, these marine megafauna face mounting threats from human activity. Overfishing, ship strikes, entanglement in plastic waste, noise pollution, and habitat loss all harm marine animals. Many of these animals are long-lived and slow to reproduce, so their numbers can't quickly bounce back once harmed. Climate change compounds these challenges by warming waters and disrupting migration and breeding patterns. Efforts to protect endangered marine megafauna According to reports, Sequeira in 2020 launched the MegaMove project, which aims to unite the marine movement ecology community to confront the urgent challenges facing ocean life. Sequeira said, 'MegaMove brings together an international network of researchers to provide innovative research to advance the global conservation of marine megafauna.' She explained, 'Our research shows that, in addition to protected areas, implementing mitigation strategies like changing fishing gear, using different lights in nets, and creating traffic schemes for ships will be key to alleviating current human pressure on these species.' Hidden routes of the big ocean creatures Currently, marine protected areas (MPAs) cover just eight percent of the world's oceans. However, the UN High Seas Treaty aims to expand that coverage to 30 percent. This new study shows that while the 30 percent goal is important, it may not be enough. The research team tracked animal movements to find areas critical for feeding, breeding, and migration. 'The impacts of a changing ocean on marine megafauna are already evident,' said Camrin Braun, assistant scientist and ocean ecologist at WHOI. 'Our recent work tracking marine predators, including an earlier WHOI-led study, indicates that changes in the ocean are expected to fundamentally alter the status quo for where these species are and how they live.' Getting ready for a changing ocean The study connects closely with the United Nations Sustainable Development Goals, particularly Goal 14, which focuses on life below water. By combining large-scale tracking data and coordinated international efforts, this research offers a clear path forward—a future where marine megafauna continue to thrive alongside a growing human presence on the seas Also read | Astronomers discover high-altitude clouds darkening skies in YSES-1 system
