Celestial slow dance over Kentucky skies to precede July's triple meteor shower
KENTUCKY (FOX 56) — A celestial slow dance will happen Tuesday night in Kentucky skies ahead of a double meteor shower at the end of the month. A post on highlighted how the moon will pass close to Saturn and Neptune on July 16, causing the two planets to be seen together in a pair of binoculars. The trifecta will linger together until the rising sun causes them to vanish from view. Read more of the latest Kentucky news While ordinarily impossible to see with the naked eye, Neptune's bluish hue can be seen just to the upper left of Saturn. In a social media post, Sky Core noted that the best viewing conditions are expected just after 9 p.m. local time. LATEST KENTUCKY NEWS: Kentucky inmate alleged tried to escape, assaulted employees Kentucky Gov. Andy Beshear tells South Carolina Democrats his record is a red state success story Joseph Lawson asks judge to throw out guilty verdict in Crystal Rogers trial Starting July 17, a roughly 2,000-year-old interstellar light show will kick off, with an expected 20 meteors an hour being possible. The Perseids are expected to run through Aug. 23, peaking around Aug. 12, joining the already active Alpha Capricornids. The following day, the Southern Delta Aquariids will complete the cosmic trifecta, according to the American Meteor Society. The Capricornids and Aquariids are expected to both peak between July 29 and July 30. According to Forbes, bright fireballs are common with the Capricornids, but only five or so shooting stars can be seen per hour. Copyright 2025 Nexstar Media, Inc. All rights reserved.

Astrophotographer captures galactic fireworks near the Seahorse Nebula in eerie deep-space photo
When you buy through links on our articles, Future and its syndication partners may earn a commission. Astrophotographer Greg Meyer has captured a spectacular image of the Fireworks Galaxy (NGC 6946) shining close to the dark shape of the Seahorse Nebula. The majestic spiral arms of the Fireworks Galaxy can be found to the lower right of Meyer's cosmic vista, surrounded by the foreground clouds of a dusty molecular cloud located within the Milky Way. The Fireworks Galaxy's nickname stems from the 10 observable supernovas seen brightening its expanse over the past century; for comparison, our galaxy is only expected to manifest one or maybe two such events over the same period of time. Lurking to the left of the Fireworks Galaxy is the star-forming region Barnard 150 — an enormous cloud of interstellar dust also known as the Seahorse Nebula, due to its striking resemblance to the tiny sea creature. The 'Ghost Bush' open star cluster is also visible to the upper right of the Fireworks galaxy, twinkling with the light of countless gravitationally bound stellar bodies. Meyer chose to frame all three objects in a single shot to create a breathtaking deep space vista. "I don't usually shoot galaxies with a telescope of just 400mm, but showing it in perspective to other objects maybe makes it more interesting as a wider shot," said Meyer in an email to As is often the case with astrophotography, the celestial objects captured in Meyer's portrait aren't anywhere near as close to one another as they appear. For example, the Seahorse Nebula orbits within the Milky Way at a distance of 1,200 light-years from Earth, while the Ghost Bush open cluster lies beyond, an impressive 5,600 light-years from our Blue Marble. The Fireworks Galaxy meanwhile is a staggering 22 million light-years from our planet. TOP TELESCOPE PICK Want to see the Seahorse Nebula? The Celestron NexStar 8SE is ideal for beginners wanting quality, reliable and quick views of celestial objects. For a more in-depth look at our Celestron NexStar 8SE review. The light that created this stunning cosmic vista was captured in the pristine skies above northern Arizona over the course of several nights in June earlier this year. Over 17 hours were spent imaging the deep sky objects with a Sky-Watcher Esprit 80mm telescope with a Player One Poseidon M pro astrophotography camera, using a range of filters and peripherals. The data was then post processed using Adobe editing software and Pixinsight. Astrophotographers looking to upgrade their gear should read our guide to the best cameras for capturing the night sky in 2025. We also have a roundup of the top lenses for astrophotography if you're looking for new glass.

Experts ask where the center of the universe is
When you buy through links on our articles, Future and its syndication partners may earn a commission. This article was originally published at The Conversation. The publication contributed the article to Expert Voices: Op-Ed & Insights. About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein's theory of general relativity. Published in 1915, and already widely accepted worldwide by physicists and mathematicians, the theory assumed the universe was static – unchanging, unmoving and immutable. In short, Einstein believed the size and shape of the universe today was, more or less, the same size and shape it had always been. But when astronomers looked into the night sky at faraway galaxies with powerful telescopes, they saw hints the universe was anything but that. These new observations suggested the opposite – that it was, instead, expanding. Scientists soon realized Einstein's theory didn't actually say the universe had to be static; the theory could support an expanding universe as well. Indeed, by using the same mathematical tools provided by Einstein's theory, scientists created new models that showed the universe was, in fact, dynamic and evolving. I've spent decades trying to understand general relativity, including in my current job as a physics professor teaching courses on the subject. I know wrapping your head around the idea of an ever-expanding universe can feel daunting – and part of the challenge is overriding your natural intuition about how things work. For instance, it's hard to imagine something as big as the universe not having a center at all, but physics says that's the reality. First, let's define what's meant by "expansion." On Earth, "expanding" means something is getting bigger. And in regard to the universe, that's true, sort of. Expansion might also mean "everything is getting farther from us," which is also true with regard to the universe. Point a telescope at distant galaxies and they all do appear to be moving away from us. What's more, the farther away they are, the faster they appear to be moving. Those galaxies also seem to be moving away from each other. So it's more accurate to say that everything in the universe is getting farther away from everything else, all at once. This idea is subtle but critical. It's easy to think about the creation of the universe like exploding fireworks: Start with a big bang, and then all the galaxies in the universe fly out in all directions from some central point. But that analogy isn't correct. Not only does it falsely imply that the expansion of the universe started from a single spot, which it didn't, but it also suggests that the galaxies are the things that are moving, which isn't entirely accurate. It's not so much the galaxies that are moving away from each other – it's the space between galaxies, the fabric of the universe itself, that's ever-expanding as time goes on. In other words, it's not really the galaxies themselves that are moving through the universe; it's more that the universe itself is carrying them farther away as it expands. A common analogy is to imagine sticking some dots on the surface of a balloon. As you blow air into the balloon, it expands. Because the dots are stuck on the surface of the balloon, they get farther apart. Though they may appear to move, the dots actually stay exactly where you put them, and the distance between them gets bigger simply by virtue of the balloon's expansion. Now think of the dots as galaxies and the balloon as the fabric of the universe, and you begin to get the picture. Unfortunately, while this analogy is a good start, it doesn't get the details quite right either. Important to any analogy is an understanding of its limitations. Some flaws are obvious: A balloon is small enough to fit in your hand – not so the universe. Another flaw is more subtle. The balloon has two parts: its latex surface and its air-filled interior. These two parts of the balloon are described differently in the language of mathematics. The balloon's surface is two-dimensional. If you were walking around on it, you could move forward, backward, left, or right, but you couldn't move up or down without leaving the surface. Now it might sound like we're naming four directions here – forward, backward, left and right – but those are just movements along two basic paths: side to side and front to back. That's what makes the surface two-dimensional – length and width. The inside of the balloon, on the other hand, is three-dimensional, so you'd be able to move freely in any direction, including up or down – length, width and height. This is where the confusion lies. The thing we think of as the "center" of the balloon is a point somewhere in its interior, in the air-filled space beneath the surface. But in this analogy, the universe is more like the latex surface of the balloon. The balloon's air-filled interior has no counterpart in our universe, so we can't use that part of the analogy – only the surface matters. So asking, "Where's the center of the universe?" is somewhat like asking, "Where's the center of the balloon's surface?' There simply isn't one. You could travel along the surface of the balloon in any direction, for as long as you like, and you'd never once reach a place you could call its center because you'd never actually leave the surface. In the same way, you could travel in any direction in the universe and would never find its center because, much like the surface of the balloon, it simply doesn't have one. Part of the reason this can be so challenging to comprehend is because of the way the universe is described in the language of mathematics. The surface of the balloon has two dimensions, and the balloon's interior has three, but the universe exists in four dimensions. Because it's not just about how things move in space, but how they move in time. Our brains are wired to think about space and time separately. But in the universe, they're interwoven into a single fabric, called 'space-time.' That unification changes the way the universe works relative to what our intuition expects. And this explanation doesn't even begin to answer the question of how something can be expanding indefinitely – scientists are still trying to puzzle out what powers this expansion. So in asking about the center of the universe, we're confronting the limits of our intuition. The answer we find – everything, expanding everywhere, all at once – is a glimpse of just how strange and beautiful our universe is.

One of the Best Meteor Showers of 2025 Is About to Begin—and It Can Be Seen Across the U.S.
The Perseid meteor shower peaks the night of Aug. 12 into the early hours of Aug. 13, with up to 100 meteors per hour visible, especially in dark-sky areas across the of the best shooting star displays of the year is coming to a sky near you. The annual Perseid meteor shower is visible across most of the U.S. from mid-July to late August. This year, the meteor shower is expected to peak on the night of Aug. 12 and before dawn on Aug. 13. According to to catch the shower's peak, you should start observing the night skies around 11 p.m. local time on Aug. 12 when the rates of shooting stars increase. The peak display will continue until dawn on Aug. 13. During this viewing window, you can expect to see an average of up to 100 meteors per hour. The Perseids meteor shower occurs when Earth passes through debris (bits of ice and rock) left behind by Comet Swift-Tuttle, a comet that is also the largest known object to repeatedly pass by Earth. The comet debris moves at around 133,200 mph in space and is typically the size of a grain of sand. The fragments become visible when they enter the atmosphere and burn up in a bright burst of light, streaking through the sky. Although the debris enters the Earth's atmosphere, it rarely hits the ground. The Perseid meteor shower is most easily seen from the Northern Hemisphere, but is also visible in the mid-southern latitudes. Although it can technically be viewed from anywhere in the U.S., the meteor shower is much easier to see in dark-sky destinations where there is less light pollution. It is also helpful to find somewhere where the sky is wide and open since buildings and mountains can obscure the view. No telescopes or binoculars are needed to see the Persied meteor shower, but recommends giving your eyes 30 minutes to adjust to the dark. It also helps to know where the meteors will come from. According to NASA, the meteor shower radiates from the Perseus constellation, which follows the easier-to-find Cassiopeia constellation across the night sky. If you can find Perseus, you'll know where the meteors will streak across the sky during the celestial event's peak. The Perseid meteor shower occurs annually in August, however in 2028, the shower is expected to evolve into a storm that will be even more spectacular than the standard, annual event.
