See the First Breathtaking Celestial Images From the Vera C. Rubin Observatory

CNETa day ago
A sneak preview of the first batch of deep space imagery from the new Vera C. Rubin Observatory in Chile made its way to news sites and social media last week, followed by a livestream event.
"(The Rubin Observatory is) going to build the greatest time-lapse movie of the cosmos ever made," the observatory said in a post.
The observatory is named for the American scientist widely credited for finding some of the first evidence of dark matter, with the project being funded by the National Science Foundation and the US Department of Energy's Office of Science.
The scientists and officials from the NSF and DOE participated in a news conference and Q&A about the findings last week. You can watch the stream below.
Millions of galaxies, big images
Though the livestream was plagued by a few technical issues, it still offered some context on what data is being captured at the Rubin Observatory and why.
"Starting today, our ability to understand dark matter, dark energy and planetary defense will grow even faster than ever before," said Brian Stone, the NSF's chief of staff.
The observatory's 3,200-megapixel camera is used for a full-sky scan that happens every three to four days. Stunning images that the observatory shares are only a fraction of what is being captured, in some cases showing only 2 percent of the full view, which would require 400 HDTVs to show.
One image can capture 10 million galaxies. Closer to Earth, astronomers have discovered 1 million asteroids in our solar system and expect to discover 5 million more in the next few years.

Tiwanaku: Pre-Incan Civilization in the Andes

Located near Lake Titicaca in Bolivia, the millennia-old city of Tiwanaku was built almost 13,000 feet (4,000 meters) above sea level, making it one of the highest urban centers ever constructed. Surrounded by mountains and hills, the city reached its peak between roughly A.D. 500 and 1000, growing to encompass an area of more than 2 square miles (6 square kilometers), organized in a grid plan. Only a small portion of the city has been excavated. Population estimates vary, but at its peak Tiwanaku may have had at least 10,000 people living in it. Although its inhabitants didn't develop a writing system and its ancient name is unknown, archaeological remains indicate that the city's cultural and political influence was felt across the southern Andes, stretching into modern-day Peru, Chile and Argentina. Today, with a modern-day town located nearby, Tiwanaku is a great ruin. "Massive, stone-faced earthen mounds rise from the plain; nearby are great rectangular platforms and sunken courts with beautiful cut-stone masonry," Denver Art Museum curator Margaret Young-Sánchez wrote in her book "Tiwanaku: Ancestors of the Inca" (University of Nebraska Press, 2004). Researchers aren't sure when Tiwanaku was first settled, but Young-Sánchez noted in her book that people in the Lake Titicaca area started settling permanently around 4,000 years ago. By this time, llamas (used as pack animals), alpacas (prized for their fur) and other camelids had been domesticated. In addition "farmers learned to cultivate hardy, frost-resistant crops like tubers and quinoa, watered by natural rainfall and water channeled from the mountain slopes," Young-Sánchez wrote. A millennium later, these adaptations had been enhanced by "raised-field agriculture" — a technique that "involves creating artificially raised planting mounds separated by canals of water," Young-Sánchez wrote. These adaptations helped usher in larger and more complex settlements, one of which, Tiwanaku, would come to dominate the region. In 2025, researchers announced they had found the stone ruins of a temple constructed by the Tiwanaku civilization. This temple, which archaeologists named Palaspata, is in Bolivia, about 130 miles (210 km) south of Tiwanaku. The terraced platform temple was large — about the size of a city block — and had interior rooms that surrounded an inner courtyard. It aligned with the solar equinox and was likely used for ceremonies, according to a study published in the journal Antiquity. Activity at the Palaspata temple thrived from about A.D. 630 to 950, according to radiocarbon dating of charcoal found at the site. The temple's strategic location linked together three trade routes, indicating that it likely connected people in the highlands to the north, the arid plateau to the west and the valleys to the east, the researchers wrote. The temple likely had religious connections, too, said José Capriles, an anthropological archaeologist at Penn State and lead author of the study. "Most economic and political transactions had to be mediated through divinity, because that would be a common language that would facilitate various individuals cooperating," he said in a statement. Archaeological excavations have revealed that the people of Tiwanaku "maintained a dense urban population residing in well-defined, spatially segregated neighborhoods, or barrios, bounded by massive adobe compound walls," Field Museum curator Patrick Ryan Williams and team noted in a 2006 journal article These "residential neighborhoods were characterized by multiple clusters of domestic structures (e.g., kitchens, sleeping quarters, storage facilities), some of which were apparently organized around a small private patio," the researchers added. Inhabitants of these clusters may have used larger, shared outdoor plazas for communal ceremonial events. Archaeologists have explored much of the city center, which contains a number of monumental structures. The area " was surrounded by an artificial moat," Young-Sánchez wrote. The area surrounded by the moat contains a number of structures that may have held religious significance. The earliest structure is likely the "Sunken Temple," a small building that is accessed via a staircase on the south, Vanderbilt University professor John Wayne Janusek wrote in his book "Ancient Tiwanaku" (Cambridge University Press, 2008). After descending the stairs, stone monoliths can be seen in the center of the room. They depict "what were most likely the more ancient and powerful mythical ancestors of the collective communities," Janusek wrote. The walls of the sunken temple are decorated with the images of god-like beings with expressionless faces and elaborate headdresses. Others look like "skulls with desiccated skin and sunken eye sockets, and still others appear to be wailing phantasms like the banshees of Irish lore," Janusek wrote. Adjacent to the Sunken Temple is a platform complex known as the "Kalasasaya," researchers Brian Bauer and Charles Stanish wrote in "Ritual and Pilgrimage in the Ancient Andes: The Islands of the Sun and the Moon," (University of Texas Press, 2001). An "artificial pyramid" known as the Akapana also resides in the area surrounded by the moat. This monument had six stone terraces, a massive 656 by 820 feet (200 by 250 m) base and was more than 54 feet (16.5 m) high, according to Bauer and Stanish's book. The Akapana dwarfed all other buildings at Tiwanaku and was likely a center of political and sacred power. When archaeologists excavated the northwest portion of the pyramid, they unearthed the skeletons of 21 people, who may have been from groups Tiwanaku conquered, according to Young-Sánchez's book. Several of the bones bear deep cut marks that suggest the bodies were hacked apart just before or soon after death, before being buried at the pyramid's base, according to the book. Outside of the moat area, and located to the southwest, is a massive, unfinished platform known as the Pumapunku (also spelled Puma Punku). The main platform was nearly 1,600 feet (488 m) wide and was covered with overlapping T-shaped terraces, according to Janusek's main entranceway was on the west side. "One moved up the stairway through stone portals, some covered with lintels carved as totora reed bundles and into a narrow, walled, passage" Janusek wrote. This passage then led to an "inner courtyard" with a "sunken paved patio." Janusek noted that water seems to have played a central role in the rites that took place on the platform. The Choquepacha spring, which is southwest of the structure, has stone conduits built around it. Around A.D. 1000, Tiwanaku fell into decline, and the city was eventually abandoned. It collapsed around the same time the Wari culture, based to the west in what is now Peru, also fell. The timing has led scientists to wonder whether environmental change in the Andes played a role in the collapse of both civilizations. But while Tiwanaku was abandoned, its memory lived on in the mythology of the people of the Andes. "Even after its abandonment, Tiwanaku continued to be an important religious site for the local people," s archaeologist Alexei Vranich wrote in an "Archaeology" magazine article. It later became incorporated into Inca mythology as the birthplace of humankind, Vranich wrote, and the Inca built their own structures alongside the ruins. Editor's note: this article was originally published on Feb. 1, 2013 and updated on July 3, 2025 to include information about the newfound Palaspata temple in Bolivia.

Astronomers Capture First-Ever Image of Star That Exploded Twice

For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but they've never seen visual evidence of this happening. That just changed. Astronomers using the Very Large Telescope in Chile have taken the first-ever image of a star that died in a stellar "double-detonation," leaving behind a spectacular supernova remnant. Their findings, published as a new study in the journal Nature Astronomy, deepen our understanding of the stellar evolution of burned-out stars called white dwarfs. "The explosions of white dwarfs play a crucial role in astronomy," lead author Priyam Das, a researcher at the University of New South Wales Canberra, Australia, said in a statement about the work. "Yet, despite their importance, the long-standing puzzle of the exact mechanism triggering their explosion remains unsolved." Once an exceptionally massive star — one at least several times heavier than the Sun — burns through all its fuel, it collapses under its own gravity in a powerful explosion known as a supernova. That's just one way supernovas can happen, though, and not all of them end the same. Some result in the star being completely obliterated, but others, if the star is heavy enough, can produce a super dense core called a neutron star, or even a black hole. The scene imaged by the VLT is the work of what's called a Type Ia supernova, produced by a low-mass star that exhausted all its fuel and left behind a remnant called a white dwarf. These objects are more compact and far denser than their original stars, endowing them with a wicked gravitational pull. In binary systems, this powerful gravity can lead to the white dwarf stripping matter off its stellar companion if their orbits are close enough. When enough of this stolen material accumulates on the surface of the white dwarf, reaching a point known as critical mass, it kickstarts a single but incredibly destructive thermonuclear explosion that wipes out both stars. That's the typical understanding. More recent research, though, has found evidence that some white dwarfs are battered by two explosions, not one, prior to winking out. In this scenario, astronomers believe that a white dwarf is swimming in a cloud of siphoned helium. This unstable helium cloud is the first to explode, precipitating a second blast in the core of the star. And bam: you have a two-fer supernova. Critically, this type of supernova occurs before the white dwarf reaches critical mass. Astronomers predicted that this double-detonation would produce a unique, visual signature in the form of two separate shells of calcium — and the new image bears this out. If you look closely, you can see that the calcium, depicted in blue, is indeed in a two-shell arrangement. This is a "clear indication that white dwarfs can explode well before they reach the famous Chandrasekhar mass limit, and that the 'double-detonation' mechanism does indeed occur in nature," said coauthor Ivo Seitenzahl, who conducted the observations while at the Heidelberg Institute for Theoretical Studies in Germany, in the statement. The work is invaluable for another reason. Type Ia explosions are considered "standard candles" that astronomers use as a measuring stick in the cosmos, because they shine at a consistent luminosity. Now we understand a little more about why that's the case. "Revealing the inner workings of such a spectacular cosmic explosion is incredibly rewarding," Das said.

‘Cool' people tend to have these six things in common, study finds

An international team of researchers may have just cracked the code for what makes someone 'cool.' And no matter where you live, the personality traits that make someone 'cool' appear to be consistent across countries, according to the study, published this week in the Journal of Experimental Psychology. The researchers found that, compared with people considered to be 'good' or 'favorable,' those considered 'cool' are perceived to be more extroverted, hedonistic, powerful, adventurous, open and autonomous. 'The most surprising thing was seeing that the same attributes emerge in every country,' said Todd Pezzuti, an associate professor of marketing at Universidad Adolfo Ibáñez in Chile who was a co-lead researcher on the study. 'Regardless of whether it's China or Korea or Chile or the US, people like people who are pushing boundaries and sparking change,' he said. 'So I would say that coolness really represents something more fundamental than the actual label of coolness.' The researchers – from Universidad Adolfo Ibáñez, the University of Arizona and the University of Georgia – conducted experiments from 2018 to 2022 with nearly 6,000 people across a dozen countries: Australia, Chile, China, Germany, India, Mexico, Nigeria, Spain, South Africa, South Korea, Turkey and the United States. The participants were asked to think of a person in their lives whom they perceive to be 'cool,' 'uncool,' 'good' or 'not good.' They were then asked to rate that person's personality using two scales: the Big Five Personality scale, a widely used scientific model that helps describe personality traits, and the Portrait Values Questionnaire, intended to measure an individual's basic values. The study participants consistently associated being calm, conscientious, universalistic, agreeable, warm, secure, traditional and conforming with being a good person, more than with being a cool person. Being capable was considered to be both 'cool' and 'good' but not distinctly either. But the formula for being 'cool' was having the six character traits – more extroverted, hedonistic, powerful, adventurous, open and autonomous – no matter the person's age, gender or education level. Pezzuti doesn't think these 'cool' traits are something that can be taught. 'We're born with those attributes,' he said. 'Five of those attributes are personality traits, and personality traits tend to be fairly stable.' The research showed that cool people and good people aren't the same, but there may be some overlapping traits, said co-lead researcher Caleb Warren, an associate professor of marketing at the University of Arizona. 'To be seen as cool, someone usually needs to be somewhat likable or admirable, which makes them similar to good people,' Warren said in a news release. 'However, cool people often have other traits that aren't necessarily considered 'good' in a moral sense, like being hedonistic and powerful.' A limitation of the research was that only people who understood what 'cool' means were included in the study. Pezzuti said it would be interesting – but difficult – to determine whether the findings would be similar among more traditional cultures or remote groups of people who may be less familiar with the term. 'We don't know what we would find in supertraditional cultures like hunting-and-gathering tribes or sustenance farming groups,' Pezzuti said. 'One thing we would propose is that in those cultures, 'cool' people don't have as important of a role because innovation, or cultural innovation, isn't as important in those cultures,' he said. 'So I would say that cool people are probably present in those cultures, but their role isn't as big, and they're probably not as admired as they are in other cultures.' When asked to think of a public figure or celebrity who embodies 'coolness' based on his research, Pezzuti immediately said Tesla and SpaceX CEO Elon Musk. 'He's a controversial figure, but someone who comes to my mind is Elon Musk,' Pezzuti said, adding that he checks all the boxes of the six attributes identified in the study. Musk is 'undeniably powerful' and autonomous, he said, and appears to be extroverted due to his presence on social media platforms and in the media. 'I hear that he's timid, maybe more timid than he seems, but from an outsider, he seems very extroverted. He's entertaining. He's on podcasts and always in front of cameras,' Pezzuti explained. Some of Musk's behavior also appears to be hedonistic, he said. 'He smoked marijuana on the most popular podcast in the world, 'The Joe Rogan Experience.'' And Pezzuti added that Musk's ideas about colonizing Mars show him to be open and adventurous. The new paper is one of the few empirical studies that examines what exactly makes people 'cool,' said Jonah Berger, an associate professor of marketing at the University of Pennsylvania's Wharton School of Business. 'While people have long wondered (and theorized) about what makes people cool, there hasn't been a lot of actual empirical research on the topic, so it's great to see work exploring this space,' Berger, who was not involved in the new paper, wrote in an email. 'While coolness might seem like something you are born with, there are certainly steps people can take to try and move in that direction,' he said. 'Given how many people want to be cool, and how much money is spent with that goal in mind, it certainly seems worth studying.' Future research in this space could evaluate coolness in tandem with goodness and badness rather than in isolation from it, said Jon Freeman, an associate professor of psychology at Columbia University. 'In real life, coolness can be a positive quality but can also have a negative connotation in certain social contexts. It may be valuable for future work to examine the differences between good coolness and bad coolness, and this study's approach offers a great foundation,' Freeman, who also was not involved in the new study, wrote in an email. 'From a scientific standpoint, cool would seem far more a product of inference and social construction than genetics, although low-level temperament informed by genetics could feed into ongoing personality construction,' he said. ''Cool' is deeply ingrained in our social vocabulary because it serves as a shorthand for complex inferences. It encapsulates signals of status, affiliation, and identity in ways that are instantaneous yet deeply stereotyped. From a scientific perspective, studying coolness is important precisely because it reveals how rapid, schematic trait inferences influence behavior and social dynamics, especially in the age of social media and influencer culture.'
