Astronaut's sublime Earth photo is surely one of his best yet

NASA astronaut Don Pettit has been back on terra firma for almost two months and he's still able to dig out some awesome photos that he took during his half-a-year stay on the International Space Station (ISS).
Pettit's latest image, posted for the first time on X on Sunday, shows the lights of cities and fishing fleets across southeast Asia, an atmospheric glow, the Milky Way, and part of the station itself as it orbited Earth 250 miles up.

The dramatic blur is caused by the extended exposure time and the motion of the orbital outpost, which is traveling through space at a speed of about 17,500 mph. The distant stars, however, remain sharp due to the use of a sidereal drive, a device that works by moving the camera at the same speed as the stars appear to move, thereby eliminating their movement within the frame.

During his recent stint aboard the space station, Pettit dazzled his many follows on X and Instagram with impressive photos and video of Earth and beyond. Check out this page where you can find some of his best work.
Pettit has spoken previously about how the cameras are set up on the ISS to give astronauts the best chance of capturing an image when something catches their eye.
'Generally speaking, we don't turn any of the cameras off,' he told Time magazine. 'We don't put lens caps on. The cameras that are staged next to the window [of the cupola] are just set up, ready to go.
'And we'll have one camera with a 200 millimeter telephoto lens, and another camera with a 14 millimeter wide angle lens, and we'll have three or four cameras set up in between, because when you're taking pictures you don't have time to change lenses. So you just grab one camera, go click click click, set it down, grab another camera, click click click, grab another camera, click click click. And there's your 10-second window to get a picture of your hometown or the Pyramids.'
Now aged 70, it's not yet clear if NASA's oldest serving astronaut will return to orbit, but happily for his fans, it seems that he's still got plenty of new content that he's eager to share.

A spinning universe could crack the mysteries of dark energy and our place in the multiverse

When you buy through links on our articles, Future and its syndication partners may earn a commission. What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole?The universe seems to be rotating, and if that is the case, then this could have major ramifications for some of the biggest questions in science, including those above. That's according to Polish theoretical physicist Nikodem Poplawski of the University of New Haven, who is well-known for his theory that black holes act as doorways to other universes. "Dark energy is one of the most intriguing mysteries of the universe. Many researchers have tried to explain it by modifying equations of general relativity or suggesting the existence of new fields that could accelerate the universe's expansion," Poplawski told "It would be amazing if a simple rotation of the universe was the origin of dark energy, especially that it predicts its weakening." Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that two-thirds of galaxies are rotating in the same direction. This suggests a lack of randomness and a preferred direction for cosmic rotation. Additionally, Poplawski pointed out that other astronomical data seem to show that the angle between the most likely axis of the spinning galaxies and the axis of the bulk flow of nearby galaxy clusters is 98 degrees, meaning they are nearly perpendicular in relation to each other. That is something that is in accordance with the hypothesis that the universe is rotating. To understand why a rotating universe implies more than one universe, Poplawski refers to "frames of reference." These are sets of coordinate systems that are integral to physics, which allow motion and rest to be measured. Imagine two scientists, Terra and Stella. Each is in their own frame of reference, but Terra on Earth, Stella in a spacecraft traveling past our planet. Terra sees Stella's frame of reference (the spacecraft) moving in relation to her own (the Earth), which is at rest. Stella, meanwhile, sees her frame of reference at rest while it is Terra's frame of reference in motion as the Earth races pointed out that if the universe is rotating, then its frame of reference is rotating, and that only makes sense if it is rotating in relation to at least one other frame of reference. "If the universe is rotating, it must rotate relative to some frame of reference corresponding to something bigger," he continued. "Therefore, the universe is not the only one; it is a part of a multiverse." For Poplawski, the simplest and most natural explanation of the origin of the rotation of the universe is black hole cosmology. Black hole cosmology suggests that every black hole creates a new baby universe on the other side of its event horizon, the one-way light-trapping surface that defines the outer boundary of a black hole. The theory replaces the central singularity at the heart of a black hole with "spacetime torsion" that gives rise to repulsive gravity that kick-starts the expansion of a new universe. "Because all black holes form from rotating objects, such as rotating stars or in the centers of rotating galaxies, they rotate too," Poplawski said. "The universe born in a rotating black hole inherits the axis of rotation of the black hole as its preferred axis." In other words, our universe may be spinning in a preferred direction because that is the way that the black hole it is sealed within is spinning. "A black hole becomes an Einstein-Rosen bridge or a 'wormhole' from the parent universe to the baby universe," Poplawski explained. "Observers in the new universe would see the other side of the parent black hole as a primordial white hole." In lieu of discovering a primordial white hole in our universe leading to our parent black hole and progenitor universe, the strongest evidence of this black hole cosmology is a preferred direction or "rotational asymmetry" in our universe. That can be seen in rotational asymmetry in the galaxies. "The motion of individual galaxies in that baby universe will be affected by the rotation of that universe," Poplawski said. "The galaxies will tend to align their axes of rotation with the preferred axis of the rotation of the universe, resulting in the rotation asymmetry, which can be observed."That's something astronomers are starting to course, that means that every black hole in our universe is a doorway to another baby cosmos. These infant universes are protected from investigation by the event horizon of their parent black holes, which prevents any signal from being received from the interior of a black a trip through this cosmic doorway would be impossible for a budding "multinaut" due to the immense gravity surrounding a black hole, which would give rise to tidal forces that would "spaghettify" such an intrepid explorer. Even if such a multinaut were to survive the journey, just as nothing can escape a black hole, nothing can enter a white hole, meaning there would be no return or opportunity to file a report! Even grimmer than this, there's no guarantee that the laws of physics are the same in a baby universe as their parent universe, meaning an unpredictable fate and potentially a messy death for a hardy multinaut able to brave a black hole doorway. Anyway, before we rush off to explore other universes, there are mysteries to be investigated right here in our own universe. At the forefront of these is the mysterious force of dark energy. Dark energy is a placeholder name given to whatever force is causing the universe to expand at an accelerating rate. Dark energy currently dominates the universe, accounting for 68% of the total cosmic matter-energy budget. This wasn't always the way, the universe's earliest epoch, it was dominated by the energy of the Big Bang, causing it to inflate. As the universe entered a matter-dominated epoch ruled by gravity, this inflation slowed to a near stop. This should have been it for the cosmos, but around 9 billion to 10 billion years after the Big Bang, the universe started to expand again, with this expansion accelerating, leading to the dark-energy dominated epoch. To understand why this is such a worrying puzzle, imagine giving a child on a swing a single push, watching their motion come to a halt, and then, for no discernible reason, they start swinging again, and this motion gets faster and faster. As if dark energy weren't strange enough already, recent results from the Dark Energy Spectroscopic Instrument (DESI) have indicated that this mysterious force is weakening. This is something that seemingly defies the standard model of cosmology or the Lambda Cold Dark Matter (LCDM) model, which relies on dark energy (represented by the cosmological constant or Lambda) being Poplawski theorizes that a spinning universe can both account for dark energy and explain why it is weakening. "Dark energy would emerge from the centrifugal force in the rotating universe on large scales," the theoretical physicist explained. "If the universe were flat, the centrifugal force would act only in directions perpendicular to the preferred axis." However, in Poplawski's black hole theory of cosmology, because the universe created by a black hole is closed, moving away in any direction would eventually lead to coming back from the opposite direction. That would mean the centrifugal force arising from a spinning universe becomes a force acting in all directions away from the universe's parent primordial white hole. "The magnitude of this force is proportional to the square of the angular velocity of the universe and the distance from the white hole," Poplawski said. "This relation takes the form of the force acting on a galaxy due to dark energy, which is proportional to the cosmological constant and the distance from the white hole. Therefore, the cosmological constant is proportional to the square of the angular velocity of the universe."But, how could this explain the DESI observations that seem to indicate that dark energy is getting weaker? "Because the angular momentum of the universe is conserved, it decreases as the universe expands," Poplawski said. "Consequently, the cosmological constant, which is the simplest explanation of dark energy, should also decrease with time. This result is consistent with recent observations by DESI."

This would help further confirm that our universe is rotating. Additionally, more data regarding how dark energy depends on cosmic distances and the progression of time in our 13.7 billion-year-old cosmos could help validate whether the weakening of dark energy is related to the decreasing angular velocity of the universe. "The next step to advance these ideas is to determine the equation describing how the cosmological constant, generated by the angular velocity of the universe, decreases with time, and to compare this theoretical prediction with the observed decrease of dark energy," Poplawski concluded. "This research might involve searching for the metric describing an expanding and rotating universe."A pre-peer-reviewed version of Poplawski's research appears on the paper repository site arXiv.

Science recap: This week's discoveries include new clues from the fossil skull of a mysterious human species

Editor's note: A version of this story appeared in CNN's Wonder Theory science newsletter. To get it in your inbox, sign up for free here. Tens of thousands of years ago, our species — Homo sapiens — mingled and interbred with other prehistoric humans: our distant cousins, the Neanderthals and Denisovans. Hundreds of Neanderthal fossils give us a good idea of their appearance, lives and relationships, but so little is known about Denisovans that they still don't have an official scientific name. Evidence of their existence has surfaced in faint traces, mapped by DNA markers that lurk in our own genetic makeup and confirmed by only a few fossil fragments. This week, however, a 146,000-year-old skull dredged out of a well in China in 2018 may just be a key missing piece to this cryptic evolutionary puzzle. The nearly complete skull did not match any previously known species of prehistoric human. But two new studies — which researchers say are among the biggest paleoanthropology papers of the year — detail how scientists were able to extract genetic material from the fossil and help unravel this biological mystery. The DNA sample taken from 'Dragon Man,' as the specimen is called, revealed that he was in fact related to Denisovans, early humans who are thought to have lived between roughly 500,000 and 30,000 years ago. The finding could be monumental, helping to paint a fuller picture of a time when our own species coexisted with other prehistoric humans. Astronomers have long grappled with the quandary of 'dark matter,' but plenty of enigmas surround regular matter as well. The proton-and-neutron-based atoms that we're familiar with are called baryonic matter. And this material is strewn between galaxies like intergalactic fog, making it extremely difficult to measure. Perhaps, that is, until now. A new study explains how scientists were able to observe the baryonic matter using the flashing of fast radio bursts. In a rare encounter, scientists have captured the first-ever footage of an elusive 3-foot-long squid alive in its deep-sea habitat. Fruit, flowers, birds and musical instruments decorated the walls of a luxury villa — part of a site the excavation team dubbed the 'Beverly Hills' of Roman Britain — before the building was razed roughly 1,800 years ago. The frescoes were painstakingly pieced together by experts from the Museum of London Archaeology. Han Li, senior building material specialist at MOLA, described the effort as a 'once in a lifetime' opportunity. Romans invaded modern-day Britain in AD 43 and established Londinium, the precursor to modern London. The occupation lasted for almost 400 years. Under the life-affirming glow of the sun, methane is a dangerous gas to be avoided. A heat-trapping chemical pollutant in Earth's atmosphere, methane exacerbates the climate crisis. But within the planet's deep recesses — thousands of feet below the ocean's surface off the US West Coast — the gas can be transformed into a nutritious meal. At least for spiders. Scientists say they've discovered three previously unknown species of sea spider living around methane seeps. In these marine habitats where sunlight can't reach, gas escapes through cracks in the seafloor and feeds bacteria that latch on to the spiders' exoskeletons. The bacteria convert carbon-rich methane and oxygen into sugars and fats the spiders can eat, according to a new study. The newfound Sericosura sea spiders may pass methane-fueled bacteria to their hatchlings as an easy source of food, the researchers suggest.

Regional students participate in University of Idaho's coding and robotics camp

Jun. 21—MOSCOW — It may not be a summer camp in the traditional sense, but the University of Idaho's summer Robotics Coding Camp is helping local students learn skills that can help them in the future. Regional middle and high school students spent a week on the Moscow campus learning about computer programming and engineering. The students typed and clicked away at their computers mastering skills many people don't learn until they are older. Erin Lanigan, UI assistant director of student engagement and STEM outreach, said one of the goals for the program is to help prepare students for entering the workforce where computer science and engineering skills are among the top needs. At this age, they are beginning to decide what they want to do when they grow up. "They have to see it to know they can be it," she said. Moscow Middle School student Corinne Bowersox, 12, already has a job in mind. "I'm actually interested in being a NASA engineer," she said. During this week's camp, she used coding to create her own video game where the goal is to catch fortune cookies and eggs before they hit the floor. She also learned how to control a small robot on wheels. She said coding is an easy way to learn a new hobby and people can share their work with other creators.
