The Guardian view on the public's dinomania: passion for palaeontology endures through the ages
On-screen discussions of DNA and off-screen scientific consultants notwithstanding, no one goes to see a Jurassic Park movie for its realism. Yet one of the less convincing moments in Jurassic World Rebirth, the latest in the franchise, is unrelated to oversized velociraptors. It's the palaeontologist Dr Henry Loomis complaining of shrinking public interest in his field. This spring, the BBC revived its 1999 hit series Walking With Dinosaurs. Not a week goes by without headlines announcing the discovery of a new species or new theories on how they behaved. Publishers produce an endless stream of dino-related fact and fiction, particularly for children. Palaeontology – at least when focused on the dinosaurs of the Mesozoic, or our hominin forebears – has long exerted an extraordinary hold on the public imagination. Yet it's a marginal field in terms of academic prestige and scientific funding, as Dr Chris Manias, a historian of science, points out in the essay collection Palaeontology in Public, published last year. (Dinosaurs are themselves a small part of the discipline; the vast mass of fossils are invertebrates, micro-organisms or plants. Good luck getting a movie made about stromatolites). The spectacular scale and fearsome nature of creatures such as Spinosaurus, the magic of conjuring extraordinary life from a handful of rocks tens of millions years old, and the mirroring of myths about dragons and other ancient beasts may all play a part in its appeal. Entertainment has always helped: the Crystal Palace dinosaurs were created in the 1850s to encourage interest in recent discoveries (Richard Owen, who coined the term dinosaur, provided advice.) Arthur Conan Doyle's 1912 novel The Lost World portrayed a South American plateau where prehistoric creatures still roamed. Some of today's palaeontologists were drawn to the field by watching the first Jurassic Park movie as children. But the science itself has been central too. In the 19th century, the US palaeontologists Othniel Charles Marsh and Edward Drinker Cope vied to outshine each other in the bitter 'Bone Wars', with academic rigour and ethics taking second place to headline-grabbing glory. In the 'dinosaur renaissance' of the 1960s, experts showed the creatures to be more sophisticated, active and interesting than previously imagined. The feathered dinosaurs found in Liaoning, China, in the 1990s have revolutionised our understanding – even if the Jurassic franchise makers, and many dinosaur fans, still draw the line at a downy Tyrannosaurus rex. In recent years, experts have identified a new dinosaur every week or so. New technology is unlocking details of their appearance and behaviour. The original Jurassic Park was a tourist resort inhabited by dinosaurs brought back from extinction. In the latest film, the plot is driven by big pharma's hunt for prehistoric DNA that could drive a medical breakthrough. That parallels the tension Dr Manias notes around palaeontology itself: is it primarily a 'luxury', which entertains more than it enlightens, or 'useful'? Jaw-dropping giants like Patagotitan still captivate adults and, especially, children. But there are lessons here too. In the past, the field appeared to offer a narrative of progress, as lumbering creatures gave way to mammals and ultimately – tada! – the triumph of humans. Now it is an instructive tale of uncertainty, offering powerful insights into time, nature and how life has fared at times of huge and rapid changes in climactic conditions.

The observatory that can reveal deepest secrets of space
The Vera C. Rubin Observatory has started operation in Chile's Atacama Desert. It's home to the largest digital camera ever made, with the goal of mapping the entire night sky in more detail than ever before. Presenter Ione Wells was granted early access to the telescope to see how this world-changing telescope works up close. This video is from Tech Now, the BBC's flagship technology programme.

Newly spotted comet is third interstellar object seen in our solar system
WASHINGTON, July 3 (Reuters) - Astronomers are tracking a newly spotted comet hailing from parts unknown, only the third time such an interstellar object has been observed visiting our solar system. According to U.S. space agency NASA, the interloper - named 3I/ATLAS - was first spotted on Tuesday by an Asteroid Terrestrial-impact Last Alert System, or ATLAS, telescope located in Rio Hurtado, Chile. Astronomers said its unusual trajectory indicated it had ventured from beyond our solar system. Journeying at a speed of around 37 miles (60 km) per second from the direction of the center of the Milky Way galaxy, 3I/ATLAS is presently located about 420 million miles (670 million kilometers) from Earth. "Beyond that we do not know very much, and there are many efforts underway to observe this object with larger telescopes to determine composition," University of Hawaii astronomer Larry Denneau, co-principal investigator for ATLAS, said on Thursday. The only other such interstellar visitors previously observed by astronomers were objects called 1I/'Oumuamua (pronounced oh-MOO-uh-MOO-uh), detected in 2017, and 2I/Borisov, discovered in 2019. "The comet has some similarities to 2I/Borisov in that it appears to be an icy comet, but it is much larger, possibly 10 km (6.2 miles) in diameter," Denneau said. "It currently has a faint coma," Denneau added, referring to the cloud of gas and dust surrounding a comet's nucleus, "but the coma and tail may increase dramatically as the object comes closer to the sun. Its closest approach to the sun will be later this year, when it will come inside the orbit of Mars. We don't know what will happen, so that's exciting." Astronomers said the comet poses no threat to Earth and will never come closer than 150 million miles (240 million km) away, equivalent to more than 1-1/2 times the distance between Earth and the sun. It is currently located about 416 million miles (670 million km) from the sun and will reach its closest approach to the sun around October 30, when it will be about 130 million miles (210 million km) away from our star. The ATLAS network is a NASA-funded telescope survey built and operated by the University of Hawaii, with five telescopes around the world that scan the night sky continuously to look for objects that could threaten Earth.
