Get Outside and Spot June's Strawberry Moon This Week
Not all full moons are created equal, and a great example of this is June's full moon, which you can check out this week. Also known as the strawberry moon, June's full moon will be one of the more interesting full moons of the year. It's a mini-moon, which means the moon is as far away from the Earth as its orbit will allow. It's also part of a major lunar standstill, which will give the moon a unique trajectory across the sky that only occurs every 18.6 years.
Your best chance to see the strawberry moon will be early on June 11, with the fullest possible moon not visible until 3:46 a.m. according to The Farmer's Almanac. It'll be only slightly less full on both June 10 and June 12.
Since it is a mini-moon, it'll also appear to be smaller and dimmer than a normal full moon. Anyone who caught one of four supermoons in 2024 will be able to spot the stark contrast between a supermoon and a mini-moon. During a supermoon, the moon is as close to the Earth as its orbit allows, a phenomenon known as perigee.
For a mini-moon, the moon is as far away from Earth as it can get, a phenomenon called apogee. It's a little less exciting than a supermoon, but for context, it's neat to know how dim and small the moon can get compared to how big and bright it can get during a supermoon.
The major lunar standstill
The strawberry moon is part of what's called a major lunar standstill. This occurs once every 18.6 years when the moon's orbit aligns just right with the Earth's tilt. As most astronomers can tell you, the moon rises and sets from different points of the horizon based on the time of year, the Earth's tilt, and the moon's orbit.
In short, the path the moon is taking through the sky is as long as it's going to get. This phenomenon isn't specific to June 2025. In fact, people will be able to view this phenomenon for most of the year. However, once it's gone, it'll be 18.6 years before it shows up again.
Another interesting tidbit about major lunar standstills is that the moon will be rising and setting on parts of the horizon where the sun will never go. This was noted by researchers at English Heritage, who are currently studying the notion that Stonehenge lines up with this once-in-a-generation event.

Astronomers capture the most intricate picture of a galaxy in a thousand colors ever seen
When you buy through links on our articles, Future and its syndication partners may earn a commission. Astronomers have obtained a stunning new image of the Sculptor Galaxy, painted in thousands of colors that reveals the intricacies of galactic systems. The incredible image of the galaxy — located around 11 million light-years away and also known as NGC 253 — was collected with the Multi Unit Spectroscopic Explorer (MUSE) instrument of the Very Large Telescope (VLT) in Chile. In addition to providing a galaxy-wide view of the Sculptor Galaxy, the image shows intricate details of NGC 253. As such, it could help to reveal the finer details of the poorly understood and complex systems that are galaxies. "The Sculptor Galaxy is in a sweet spot," team leader Enrico Congiu of the Universidad de Chile said in a statement." It is close enough that we can resolve its internal structure and study its building blocks with incredible detail, but at the same time, big enough that we can still see it as a whole system." Covering 65,000 light-years of the 90,000-light-year-wide galaxy, zooming in on the finer details of the Sculptor Galaxy to create this image required 100 exposures collected over 50 hours of MUSE observing time. That effort was justified by the unprecedented detail revealed in the Sculptor Galaxy VLT image.

An initial examination of the image has already paid dividends for the team. Within the image, they have been able to discover 500 new planetary nebulae, shells of gas and dust that are ejected from stars like the sun after they "die" and enter a "puffed out" red giant phase. This is pretty extraordinary, because detections like this beyond the Milky Way and its immediate neighbors are fairly rare. "Beyond our galactic neighborhood, we usually deal with fewer than 100 detections per galaxy," said team member and Heidelberg University researcher Fabian Scheuermann.

"Finding the planetary nebulae allows us to verify the distance to the galaxy — a critical piece of information on which the rest of the studies of the galaxy depend," explained team member and Ohio State University researcher Adam Leroy. That's not to say that the team is finished with this image of the Sculptor Galaxy just yet. The next step for the astronomers will be to explore how hot gas flows through NGC 253, changing composition and helping to create new stars. "How such small processes can have such a big impact on a galaxy whose entire size is thousands of times bigger is still a mystery," Congiu concluded. The team's research was published online June 18 in the journal Astronomy & Astrophysics. This article was originally published on

It turns out weather on other planets is a lot like on Earth
Related : Advertisement But by leveraging the sheer amount of knowledge and data about our planet, scientists can get a head start on understanding the inner workings of storms or vortexes on other planetary bodies. In some cases, the models provide almost everything we know about some otherworldly atmospheric processes. 'Our planetary atmosphere models are derived almost exclusively from these Earth models,' said Scot Rafkin, a planetary meteorologist at the Southwest Research Institute. 'Studying the weather on other planets helps us with Earth and vice versa.' Satellite photo of the Baltic Sea surrounding Gotland, Sweden, with algae bloom swirling in the water. The churning clouds near Jupiter's pole appear like ocean currents on Earth — as if you're looking at small edges and meandering fronts in the Baltic Sea. European Space Agency Vortexes on Jupiter If you looked at the churning clouds near Jupiter's pole, they appear like ocean currents on Earth - as if you're looking at small edges and meandering fronts in the Baltic Sea. 'This looks so much like turbulence I'm seeing in our own ocean. They must be covered by at least some similar dynamics,' Lia Siegelman, a physical oceanographer at Scripps Institution of Oceanography, recalled the first time she saw images of vortexes from NASA's Juno mission, which entered Jupiter's orbit in 2016. Advertisement Working with planetary scientists, she applied her understanding of the ocean physics on Earth to the gas giant in computer models. Whether it's in air or water on any planet, she found the laws of physics that govern turbulent fluids is the same (even though the vortex on Jupiter is about 10 times larger than one on Earth). When cyclones and anticyclones (which spin in the opposite direction) interact in the ocean, they create a boundary of different water masses and characteristics - known as a front. She and her colleagues found the same phenomenon occurs in cyclones at Jupiter's poles, showing similar swirls. 'By studying convection on Earth, we were also able to spot that phenomenon occurring on Jupiter,' Siegelman said, even though Jupiter has relatively little data compared to Earth. Related : She and her colleagues also found a pattern never seen on Earth before: a cluster of cyclones in a symmetrical, repeating pattern near the poles of Jupiter. These 'polar vortex crystals' were observed in 2016 and have remained in place since. Despite never seeing them on Earth, she and other planetary scientists collaborated to reproduce these swirls in computer models - relying on 'just very simple physics.' 'Planetary scientists use a lot of the weather models that have been developed to study either the ocean or the atmosphere,' Siegelman said. 'By just knowing so much about the ocean and the atmosphere, we can just guide our analysis.'

HANDOUT Dust storms on Mars If you plan to move to Mars, be prepared to face the dust storms. At their most intense, they can engulf the entire planet and last from days to months. The dirt can block sunlight and coat infrastructure. While scientists have observed many of these storms, they still don't know how to predict them. Dust storms operate similarly on Earth and Mars. Dust is lifted and heated, and rises like a hot-air balloon, Rafkin said. The rising air will suck in air from below to replace it. Air pressure drops near the surface, sucking in more wind that lifts the dust. As Mars spins, the angular momentum causes the dust storm to rotate. In reality, Martian dust storms are more similar to hurricanes on Earth in terms of their scale and circulation, said planetary scientist Claire Newman. She said the sources are different (Mars is a dust planet, whereas Earth is a water planet), but they have a similar effect on temperature and winds. But it's still unknown how these Martian dust storms form. On Earth, a winter storm with a cold front can lift the dust; scientists sometimes see similar dust lifting along cold fronts on Mars, but many storms just seem to pop up. Related : To predict a dust storm, scientists need to understand the circulation patterns on Mars - forecasting the cold front that can lift the dust, for instance. But it's something researchers don't yet understand. Wind measurements are scarce on Mars, aside from a few scattered measurement sites on its surface. With adjustments, Earth-based models can simulate the conditions that can lead to the uplifting winds and dust storms. 'Almost everything that we know about the circulation patterns on Mars come from models,' said Rafkin, adding that scientists 'have effectively no observations of the movement of the air on Mars.' Advertisement In this photo, sand blowing off fields creates a dust storm near Morton, Texas, in May 2021. Dust storms operate similarly on Earth and Mars. Jude Smith/Associated Press The models currently serve as the best way to understand dust storms on the Red Planet, unless more dedicated studies and stations are added, similar to Earth. 'We're basically applying these models to try and get a sense of what the environment is,' said Newman, 'before we send robots or potentially people there.' Rain on Titan The second-largest moon in our solar system, Titan is the only other known world besides Earth that has standing bodies of rivers, lakes and seas on its surface - consisting of liquid methane instead of water. That's partly why some scientists think it could be a future home for Earthlings, if we can just figure out the 750-million-mile journey and learn how to survive the minus-179 degree Celsius surface temperatures. But how did those lakes and oceans fill up? Even though it rains methane, the precipitation on Titan is very similar to that on Earth, Rafkin said. On Earth, take a chunk of air with water vapor, cool it off and the air becomes saturated to form a cloud. Those small cloud droplets can bump into one another or take in more water vapor to grow bigger. But eventually, the water vapor starts to condense into a liquid and brings rain. We've seen this process take place on Earth both naturally in the atmosphere and in labs enough times to understand the physics. But limited observations on Titan - effectively only visiting its atmosphere a handful of times - have caused scientists to turn to models. Using the same underlying physics, scientists can model the cloud-making process on this foreign body. And, the modeled clouds look a lot like the few they have observed in real life on Titan. Advertisement This November 2015 composite image made available by NASA shows an infrared view of Saturn's moon, Titan, as seen by the Cassini spacecraft. Titan is the only other known world besides Earth that has standing bodies of rivers, lakes and seas on its surface. AP 'If we try to model them and we get clouds, but they look totally bizarre and different than what we're observing, then that's an indication that maybe we're not representing the cloud processes correctly,' Rafkin said. 'But as it turns out, for the most part, when we model these things, we can produce clouds that look reasonably close to what we've observed.' Because of its incredibly dense atmosphere, Titan has storm clouds - two to four times taller than those on Earth - that are able to produce feet of methane rain. While scientists haven't observed such huge volumes, they have modeled the deluges based on the surface darkening as a storm passed - similar to how rain on soil or pavement darkens the surface on Earth. It's still a mystery where the methane comes from. But at least we know to bring a very, very sturdy raincoat if we ever visit Titan.

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.
