Nasa has received “puzzling” data from a spacecraft that was studying a distant asteroid. The space agency’s Lucy Spacecraft left Earth in 2021, with the aim of studying “Jupiter trojans”, a set of asteroids that fly around the Sun along Jupiter’s orbit and remain largely mysterious. Recently, scientists decided to send it to visit another small object on its way, largely as a test of the systems on the spacecraft that let it track asteroids for its mission. When Lucy arrived at that object – a main belt asteroid named Dinkinesh – it found a surprise, however. Images taken of the asteroid showed that it had a satellite, which flies around the asteroid like a tiny moon of its own. Now, further examination of those images show that the satellite is not one but two objects. Those objects make up a “contact binary”, or two smaller objects that are touching each other as they fly through space. The unexpected discovery explains some of the strange data that scientists had received as they approached Lucy. But it opens up more confusion about the whole system, which one called “bizarre”. “Contact binaries seem to be fairly common in the solar system,” said John Spencer, Lucy deputy project scientist, in a statement. “We haven’t seen many up-close, and we’ve never seen one orbiting another asteroid. “We’d been puzzling over odd variations in Dinkinesh’s brightness that we saw on approach, which gave us a hint that Dinkinesh might have a moon of some sort, but we never suspected anything so bizarre!” The flyby of Dinkinesh was only intended as a test of the spacecraft’s systems but has now posed new possible research for scientists. “It’s truly marvelous when nature surprises us with a new puzzle,” said Tom Statler, Lucy program scientist from NASA Headquarters in Washington. “Great science pushes us to ask questions that we never knew we needed to ask.” “It is puzzling, to say the least,” said Hal Levison, principal investigator for Lucy, also from Southwest Research Institute. “I would have never expected a system that looks like this. In particular, I don’t understand why the two components of the satellite have similar sizes. This is going to be fun for the scientific community to figure out.” The scientists were only able to confirm the nature of the system with the multiple images that were sent back by Lucy in the wake of its encounter with Dinkinesh. Nasa is working now to get the rest of the data from the spacecraft, which might include yet more surprises. Lucy itself will continue flying through space on a journey that is due to take 12 years. Lucy is actually heading back to Earth, which it will use for a gravity assist to propel it onto the next part of its journey, back through the main asteroid belt and onto the Trojan asteroids.

The solar system is famously vast, but new data from scientists has revealed that it extends even further than once thought. It is a discovery that was made thanks to distant objects that were spotted during a scan of telescope images. They appeared to show faint signs of rock located beyond Pluto, suggesting that the material of the solar system extends further into interstellar space than was previously believed. The new method of looking at telescope images has dispelled decades of hypotheses from astronomers who believed that the Kuiper Belt, a circumstellar disc in the outer solar system, becomes suddenly more sparse from 48 times the distance between Earth and the Sun. But, belts of rubble have now been seen extending out more than twice the distance experts previously thought. The discovery was made by a team of astronomers who were led by Canada's Herzberg Astronomy and Astrophysics Research Centre who were on a mission to find new targets for the probe “New Horizons” to explore on its way through the outer reaches of the solar system. With light at the end of the solar system in short supply, experts realised if they stacked multiple images taken at different times, they could combine the light to increase the visibility of an object, increasing its visibility. Using machine learning to help them on their way, experts trained the system before testing it with real data captured from the Subaru Telescope on Mauna Kea in Hawaii. In comparison to humans, the technology identified more than double the amount of Kuiper Belt Objects, revealing to experts just how vast the solar system is. They presented their findings at the 54th Lunar and Planetary Science Conference 2023. While the team’s results have not yet been peer-reviewed, they appear to suggest that our solar system has a minimum of two rings of material stretching as far as the distance Pluto is from planet Earth.

iPhone users have been urged to download a new update immediately. The update was pushed out by Apple to iPhones and iPads after a major security vulnerability was found in the devices. Patching up that hole with the new software update should keep those devices safe. But without it, attackers could break into an iPhone and spy on its user. The security issue was found by researchers at the University of Toronto’s Citizen Lab. They said the problem was being “actively exploited” by hackers, and that all users should update immediately. They were doing so by delivering commercial software called Pegasus, which is made and sold by Israeli company the NSO Group. That software is expensive and targeted, and has primarily been used on specific activists, journalists and politcians, who are likely to know if they are at particular risk of an attack. The latest attack was used on the iPhone of a member of staff at a US civil society organisation with international offices, Citizen Lab said. It named the new exploit BLASTPASS and said that it did not even require users to click anything on their device. The NSO Group and Apple have in recent years been engaged in a long-running fight to find and fix security flaws that could allow for the delivery of that software. Recent iPhone updates brought a new “Lockdown Mode” that places extra restrictions on the device in an attempt to close up potential security flaws. That includes not downloading images that could include spyware, for instance – which is how attackers deliver the hack in this most recent scare. Downloading the new update is simple. It is done through the Settings app on iPhones and iPads, by clicking the “general” and then “software update” options – that will check for any new updates, and offer the option to download it. Phones may eventually automatically install the new operating system, which could mean that no download shows up in that screen. Users can check if they have already updated to the new, patched operating system by clicking the “about” option in the general settings, and looking whether they have the newest iOS 16.6.1. Similar updates are available for Macs and Apple Watches, and are installed in much the same way. Citizen Lab also advised that anyone “who may face increased risk because of who they are or what they do” should switch on Lockdown Mode. Apple confirmed that would block the new attack, researchers said.
