GALACTIC SHOWDOWN: QUASAR ZAPS GALAXY IN EPIC COSMIC DUEL Astronomers have caught two galaxies in a cosmic duel that would make any medieval knight jealous. One galaxy used its secret weapon a quasar a blinding beam of energy powered by a supermassive black hole to blast its rival into... pieces. This cosmic standoff happened 11 billion years ago when the Universe was a teenager at just 18 percent of its current age. The quasar’s beam stripped away gas clouds in the other galaxy shrinking them so they could no longer make stars. It was like the quasar slammed the door on its opponent’s future. Researchers used powerful telescopes in Chile’s Atacama Desert to watch this drama unfold. ALMA’s sharp vision and VLT’s precise measurements let them see how the quasar’s energy gutted the other galaxy. Meanwhile the quasar feasted on the chaos pulling in even more gas to power its deadly glow. Scientists think more of these cosmic jousts are out there waiting to be discovered. The next time you see a star twinkle remember it might just be the last light of a cosmic feud that never ended. Source: SciTech Dailyshow more

Galactic duels? Now that's a cosmic battle worth watching! Who knew the universe had its own version of Game of Thrones? Quasars are basically the lightsabers of space—blinding and powerful. Can't wait to see what other secrets the cosmos has up its sleeve!

Whoa, that's straight-up space warfare! A quasar blasting a rival galaxy apart feels like sci-fi, but it’s just another wild chapter in our universe’s history.

The Milky Way galaxy alone still holds many mysteries and so much we have yet to discover. Observing other galaxies must be beyond our imagination.

$Scientists discovered a galaxy so enormous that it almost doesn't seem real. Known as IC 1101, this cosmic giant may contain nearly a trillion stars, making it one of the largest galaxies ever discovered. For comparison, our own Milky Way contains only a fraction of that number. The scale of IC 1101 is almost impossible to imagine. If our Sun were just one of its stars, there would still be hundreds of billions more spread across this colossal galaxy. And the craziest part? Despite its unbelievable size, IC 1101 is just one galaxy among billions scattered throughout the universe. Which means the cosmos may be far larger than we can truly comprehend. 🌌✨⭐ #space #galaxy$

BLACK HOLE BOSS LEVEL: SCIENTISTS FIND HIDDEN MONSTER IN NEARBY GALAXY For years, astronomers thought the galaxy M83 was just vibing without a giant black hole — turns out, it was just hiding behind a mountain of space dust. Thanks to the James Webb Space Telescope’s insane mid-infrared vision, scientists spotted supercharged neon gas that only something like a black hole could fire up. Basically, M83 had a secret boss battle happening in its core this whole time, and we finally caught it cheating with mega-energy we couldn't see before. More telescopes are lining up to double-check, but honestly, the universe just keeps flexing harder than anyone expected. Source: Phys .org

Brian Cox is pointing at one dot. The dot is a galaxy with 100 billion stars. There are 200 billion more on the same map. The thin line at the top of that map represents a billion light-years. At the speed of light, it would take a billion years to cross that sliver. The math gets stranger. The observable universe holds roughly 30 sextillion stars. Every grain of sand on every beach on Earth combined is about 7.5 sextillion. The universe has 4x more stars than Earth has sand. The deeper number is which of those galaxies you can ever actually reach. Dark energy is accelerating cosmic expansion. Space itself is stretching faster than light can cross it. The cosmic event horizon sits at roughly 16 billion light-years from Earth. Anything past that is moving away from us faster than light can chase. We can see those galaxies because their photons left billions of years ago when the gap was small enough. We cannot reach them. We cannot send a signal. We cannot know what they look like now. 97% of the galaxies on Cox's map are already disconnected from our future. Visible artifacts of a past that has ended. Now look forward. In about 150 billion years, accelerating redshift will push every galaxy outside our Local Group beyond detection. Andromeda will have merged with the Milky Way. The other 199,999,999,999 galaxies will be invisible. Civilizations on planets around future stars will look up and see only one galaxy. Their telescopes will tell them the universe ends at the edge of the Local Group. They will not see cosmic background radiation. They will not observe expansion. They will not know about the Big Bang. The evidence will have receded past their light cone. Every astronomy textbook they could ever write would conclude the universe is small, static, and made of one galaxy. We exist in a 100-billion-year window where the universe is still legible. Before us, too hot, too dense, too young. After us, the lights go out one galaxy at a time. 30 sextillion stars on the map. A 100-billion-year window in which to read it. We exist inside the only overlap.

Every time you look at the stars, you are literally looking back in time. As Professor Brian Cox explains, because light takes time to travel through the vastness of space, we see the Andromeda Galaxy not as it is today, but as it was 2 million years ago. This means that if we look deep enough into the cosmos, we can actually see the oldest light in existence—the Cosmic Microwave Background Radiation—a glowing echo that began its journey 13.8 billion years ago, right at the very dawn of the universe.

THE EDGE OF FOREVER Right now, about 16 billion light years from Earth, lies the ultimate “No Entry” sign. Not a wall. Not a force field. Just physics. Einstein laid it down: nothing outruns light. But the universe has other plans. Space itself expands - stretching like an endless sponge. The farther away a galaxy is, the faster it sprints from us. Even if you rode a beam of light with a rocket strapped to its back, you’d never catch them. That invisible limit is our cosmic event horizon - the real edge of the observable universe. Everything past it? It’s not just hidden. It’s sealed away by time itself. Source: theoretical_tales

What lies at the center of our galaxy? In Jules Verne's science fiction classic, A Journey to the Center of the Earth, Professor Liedenbrock and his fellow explorers encounter many strange and exciting wonders. Astronomers already know of some of the bizarre objects that exist at our Galactic Center, including vast cosmic dust clouds, bright star clusters, swirling rings of gas, and even a supermassive black hole. Much of the Galactic Center is shielded from our view in visible light by the intervening dust and gas, but it can be explored using other forms of electromagnetic radiation. The featured video is actually a digital zoom into the Milky Way's center which starts by utilizing visible light images from the Digitized Sky Survey. As the movie proceeds, the light shown shifts to dust-penetrating infrared and highlights gas clouds that were recently discovered in 2013 to be falling toward the central black hole.

Earth orbits the Sun, and the Sun orbits the center of the galaxy... but what is the Milky Way itself orbiting? The Milky Way is not orbiting a single object. Instead, it is moving around a shared center of mass alongside the Andromeda galaxy. While most of the universe is being pushed apart by dark energy, the gravity within our "Local Group" is strong enough to pull these two galaxies toward each other in a slow "cosmic dance." This movement isn't a clean, circular orbit; it is a direct path toward a massive collision and merger that will occur in about 4 to 5 billion years.

A supernova explosion in the galaxy NGC 2442 This distant explosion occurred approximately 60 million years ago, around the time the dinosaurs on Earth were going extinct. The dying star's luminosity was billions of times greater than that of our Sun and comparable to the entire center of the galaxy NGC 2442. Such supernovae are among the brightest and most powerful events in the Universe, leaving behind remnants and influencing the evolution of surrounding matter. This cosmic explosion is a reminder of the scale and dynamics of our universe, and how events millions of light-years away can coincide with important stages in the history of life on Earth.

Supernova in the galaxy NGC 2525 A supernova explosion was recorded in the spiral galaxy NGC 2525 in early 2018. More precisely, the explosion occurred about 70 million years ago, when dinosaurs were still roaming the Earth, but its light only reached us in 2018. At its peak, this supernova was 5 billion times brighter than the Sun! However, as usually happens, after a few months its light began to fade, and now it is no longer visible. Immediately after the explosion was detected, the Hubble telescope began regularly photographing the galaxy NGC 2525. The presented timelapse covers a whole year of observations, demonstrating how the supernova gradually faded in brightness.

NASA JUST MADE A 3D COSMIC CLIFF TOUR — AND IT’S ABSURDLY EPIC NASA turned James Webb Space Telescope data into a full 3D fly-through of the Cosmic Cliffs — a star-forming region in the Carina Nebula that makes Earth’s mountains look like molehills. Located 7,600 light-years away, this isn’t rock — it’s pure gas and radiation, sculpted by young stars like a cosmic blowtorch. The visualization fuses data from Webb, Hubble, Spitzer, and Chandra to show dust pillars, jet streams, and stellar winds in full 3D glory — including one massive protostellar jet slicing through the scene. If you stood on one of these “cliffs”? Everest would look like a pebble. Space just went IMAX. Source: TechEBlog / NASA

PROF. BRIAN COX: THE UNIVERSE MAY BE INFINITE "There are roughly 2 trillion galaxies - we haven't counted them all, but that's an estimate based on surveys of the local universe. The Milky Way has 400 billion stars in it, and it takes light over 100,000 years to cross a galaxy.

Finding alien life wouldn't be terrifying. It would be a profound relief. As Professor Brian Cox explains, the thought that keeps him awake at night is the possibility that complex life is so incredibly rare that Earth might be the only inhabited planet in the entire Milky Way galaxy. If we are truly alone, it means that if humanity destroys our world, we aren't just ending our own story. We could be permanently extinguishing all intelligence and meaning in a galaxy of 400 billion stars; a terrifying cosmic burden that he hopes we do not have to carry by ourselves.

REBEL PLANET DEFIES SPACE RULES WITH WILD POLAR ORBIT Astronomers have discovered a planet that is breaking all the normal space rules. Named 2M1510 b, this planet ignores the usual neat and flat orbit that most planets stick to and instead takes a crazy ride over the poles of its 2 stars, looping around at a sharp 90-degree angle. In our solar system, planets calmly glide in flat paths around their stars. But 2M1510 b decided that was boring. It was found using the Very Large Telescope in Chile, not by being seen directly but by measuring how it tugs on its 2 brown dwarf stars. Brown dwarfs are odd objects, too big to be planets but too small to glow like stars. These 2 brown dwarfs circle each other every 21 days while a third one drifts far away. To find 2M1510 b, scientists used a clever trick called “radial velocity,” watching for tiny wobbles in the stars’ light. The wobbles were like the stars saying, “Something is pulling on us out here.” Out of the more than 5,800 known planets around other stars, only 16 orbit two stars. None of them are known to spin over the poles like this. It is as if 2M1510 b looked at the galaxy’s playbook and decided to write its own chapter. Source: SciTech Daily

Captain Cosmic, Bay Area superhero. Captain Cosmic was a late-afternoon weekday show that aired on KTVU from September 1977 to January 1980. It was created and hosted by Bob Wilkins, who was also the creator and host of Creature Features, a late-night horror movie program that ran in the Bay Area from 1971 to 1984. In many ways, Captain Cosmic was a companion show to Creature Features, just aimed at a younger audience. The show primarily featured serials starring Japanese superheroes, including Ultraman, Spectreman, Star Blazers, Godzilla, Johnny Sokko and His Flying Robot, Captain Scarlet and the Mysterons, and the original Flash Gordon serials. Within three weeks of its debut, Captain Cosmic became the number one kids' show in the Bay Area. If you want to go check out Captain Cosmic's sidekick, Wonder Robot 2T2, and see it in person, it currently resides at Atlantis Fantasyworld in Santa Cruz. source footage 🎥: KTVU

Carl Sagan explains why humanity’s oldest illusion collapses the moment we look at the real scale of the universe. “Here we are, like mites on a plum. And the plum is this little planet.” “And the plum goes around an insignificant local star, the Sun.” “That star is on the obscure outskirts of an ordinary galaxy, the Milky Way.” “The Milky Way contains hundreds of billions of other stars.” “And this galaxy is only one among billions of other galaxies that make up the universe.” “Now it is beginning to look as if even this universe may be one of an enormous number, maybe even an infinite number, of other closed-off universes.” “So the idea that we are central…” “That the reason there is a universe is us, is pathetic.” “We have to understand the universe that we really live in.” “Some of our myths and some of our religion are inconsistent with it.” “It is time to change the myth.”

THE UNIVERSE IS WAY BIGGER THAN YOUR BRAIN CAN HANDLE Every star you see at night? That’s just our galaxy, the Milky Way. A single neighborhood with 100,000 light-years of real estate and over 100 billion stars. Some are so big they’d make our Sun look like a flashlight. Now zoom out. There are over 2 trillion galaxies. Each one with billions of stars and planets we’ll never see. Light from some of them has been traveling for billions of years… and still won’t ever reach us. When you look up, you’re not seeing the universe. You’re seeing your cosmic driveway, while the rest of creation rages beyond the horizon. Source: @cosmic_curios1

A one-in-a-million chance—and it happened. A team from the Technical University of Munich spent six years compiling a list of promising gravitational lenses and waiting for a supernova to explode behind one of them. In August 2025, it happened. A superluminous supernova 10 billion light-years away was located precisely behind two foreground galaxies—and its light, bent by gravity, produced five images of the same explosion. Typically, lenses produce two or four—five was a surprise even to the authors. The supernova was named SN Winny. The odds of such a coincidence are less than one in a million. But the value of the discovery is enormous. Light from the supernova travels to us along different paths around the lensing galaxies, and each path has its own length. Because of this, the five copies appear with different time delays. By measuring these delays and knowing the mass distribution in the lensing galaxies, one can directly calculate the Hubble-Lemaître constant, or the rate of expansion of the Universe. How is this better than existing methods? The classic "cosmic distance scale" is a multi-step process, with errors accumulating from step to step. Microwave background radiation measurements are precise, but depend on models of the evolution of the Universe. The lensed supernova method is a single-step process, with completely different sources of error. SN Winny is particularly convenient: it is lensed by just two individual galaxies with a simple mass distribution, rather than a complex cluster. SN Winny is currently being observed by telescopes around the world. The results could bring us closer to resolving the Hubble controversy—the discrepancy between the two main methods for measuring the expansion rate.

Typically, lenses produce two or four—five was a surprise even to the authors. The supernova was named SN Winny. The odds of such a coincidence are less than one in a million. But the value of the discovery is enormous. Light from the supernova travels to us along different paths around the lensing galaxies, and each path has its own length. Because of this, the five copies appear with different time delays. By measuring these delays and knowing the mass distribution in the lensing galaxies, one can directly calculate the Hubble-Lemaître constant, or the rate of expansion of the Universe. How is this better than existing methods? The classic "cosmic distance scale" is a multi-step process, with errors accumulating from step to step. Microwave background radiation measurements are precise, but depend on models of the evolution of the Universe. The lensed supernova method is a single-step process, with completely different sources of error. SN Winny is particularly convenient: it is lensed by just two individual galaxies with a simple mass distribution, rather than a complex cluster. SN Winny is currently being observed by telescopes around the world. The results could bring us closer to resolving the Hubble controversy—the discrepancy between the two main methods for measuring the expansion rate.
