It’s only a matter of time before we find the aliens, scientists say. So what should happen next?

Neptune and Uranus are the seventh and eighth planets from the sun, and as such share a lot of the same characteristics. Though they are different colors (Neptune is bluer than Uranus’ cyan hue) and have different numbers of rings and moons, both planets are ice giants that are similar sizes at just over 30,000 miles (50,000 kilometers) wide each. They also weigh about the same, with Neptune coming in at 1.024 × 1026 kg (about 17 times the mass of Earth) and Uranus weighing 8.682 × 1025 kg (about 14 times the mass of Earth). What’s more, both planets have upper atmospheres made up of mostly hydrogen, helium, and methane. Put simply, then, the characteristics of Neptune and those of Uranus are very similar despite their different colors.
Now, it seems the two worlds could have yet another thing in common, and this one is particularly intriguing when compared with Earth. Neptune and Uranus might be home to some incredibly deep oceans that make our own look like puddles.
Earth’s own oceans are already mysterious enough. They cover roughly 70% of the planet’s surface, yet only a small portion of our ocean has been explored, with the Nippon Foundation-Gebco stating that as of June 2024, just 26.1% of the entire seafloor had been mapped. The deepest trench in the ocean, known as the Challenger Deep, sits beneath the western Pacific Ocean, southwest of the U.S. territorial island of Guam, and is roughly 35,876 feet deep. Just what life is like at such depths remains somewhat of a mystery, with the deep ocean already proving to be home to prehistoric sea animals that are, frankly, nothing short of nightmare fuel. But the deepest ocean trenches on Earth are absolutely nothing compared to the depths of the oceans that might well exist on Neptune and Uranus.
As civilizations advance, they may need to migrate across the galaxy, and some researchers speculate they could use their own stars as massive engines.
New research explores the possibility of a binary stellar engine, particularly spider pulsars, as potential propulsion systems. By carefully manipulating these systems, a highly advanced extraterrestrial species.
A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.
Imagine a scale that ranks civilizations not by their borders or technology, but by the sheer energy they command— some spanning entire galaxies. Join us as we explore the Kardashev Scale, the ultimate measure of cosmic power.

Quantum physics, space documentary, and the fabric of reality—these are not just abstract ideas but the keys to unlocking the mysteries of existence. What is reality? Is it an illusion, a simulation, or something far beyond our comprehension? In this mind-expanding documentary, we explore the very fabric of the universe, from the bizarre behavior of quantum mechanics to the cosmic forces shaping space and time.
The universe is a grand puzzle, and science has only begun to unravel its secrets. Quantum physics reveals a world where particles exist in multiple states at once, where time behaves unpredictably, and where observation itself shapes reality. But how does this strange quantum realm connect to the vast expanse of space? Is the fabric of reality woven with unseen forces that govern everything, from black holes to the flow of time itself?
This space documentary takes you on a journey through the cutting-edge theories that challenge our understanding of the cosmos. Could our universe be a hologram? Is time an illusion? Do parallel realities exist beyond our perception? With stunning visuals, expert insights, and mind-bending concepts, we push the boundaries of what we know about existence.

“We’ve found that Enceladus’ ocean should behave like oil and water in a jar, with layers that resist vertical mixing,” said Flynn Ames.
Could finding life in alien oceans be harder than previously thought? This is what a recent study published in Communications Earth & Environment hopes to address as a team of researchers from the United Kingdom investigated how life that might exist in the depths of alien oceans like Saturn’s moon, Enceladus, could take time to reach the surface for sampling, which could potentially pose problems for future sample return missions to these intriguing worlds.
For the study, the researchers used a series of computer models to simulate the various layers that could exist between the liquid ocean of Enceladus and the plumes that discharge from its south polar regions, nicknamed “tiger stripes” for its giant ice cracks. Given the sampling potential of the plumes, especially with NASA’s Cassini spacecraft having flown through the plumes during its mission, the researchers wanted to ascertain the length of time material from potential hydrothermal vents at the bottom of the ocean would reach the surface to be discharged by the plumes and sampled for signs of life. In the end, the researchers found that material from the bottom of Enceladus’ would take several centuries to reach a plausible depth to be discharged by the plumes.

📄A group of American researchers, isolated in their scientific station in Antarctica towards the end of winter, discover an alien spaceship buried in the ice, where it crashed twenty million years before. They try to thaw the inside of the spacecraft with a thermite charge but end up accidentally destroying it when the ship’s magnesium hull is ignited by the charge. They do recover an alien creature from the ancient ice, which the researchers believe was searching for heat when it was frozen. Thawing revives the alien, a being which can assume the appearance, memories, and personality of a living thing it devours, while maintaining its body mass for further reproduction. Unknown to them, the alien immediately kills and then imitates the crew’s physicist, a man named Connant; with some 90 pounds of its matter left over, it tries to become a sled dog. The crew discovers the dog-Thing and kills it midway through the transformation process. Pathologist Blair, who had lobbied for thawing the Thing, goes insane with paranoia and guilt, vowing to kill everyone at the base to save mankind; he is isolated within a locked cabin at their outpost. Connant is also isolated as a precaution, and a “rule-of-four” is initiated in which all personnel must remain under the close scrutiny of three others.
The crew realizes that they must isolate their base and therefore disable their airplanes and vehicles, yet they pretend that everything is normal during radio transmissions, to prevent any rescue attempts. The researchers try to figure out who may have been replaced by the alien (simply referred to as the Thing), to destroy the imitations before they can escape and take over the world. The task is found to be almost impossibly difficult when they realize that the Thing is shapeshifting and telepathic, reading minds and projecting thoughts. A sled dog is conditioned by human blood injections (from Copper and Garry) to provide a human-immunity serum test, as in rabbits. The initial test of Connant is inconclusive, as they realize that the test animal received both human and alien blood, meaning that either Doctor Copper or expedition Commander Garry is an alien. Assistant commander McReady takes over and deduces that all the other animals at the station, save the test dog, have already become imitations; all are killed by electrocution and their corpses burned.
Everyone suspects each other by now but must stay together for safety, deciding who will take turns sleeping and standing watch. Tensions mount and some men begin to go mad, thinking that they are already the last human, or wondering if they could know if they were not human any longer. Ultimately, Kinner, the cook, is murdered and accidentally revealed to be a Thing. McReady realizes that even small pieces of the creature will behave as independent organisms. He then uses this fact to test which men have been “converted” by taking blood samples from everyone and dipping a heated wire in the vial of blood. Each man’s blood is tested, one at a time, and the donor is immediately killed if his blood recoils from the wire. Fourteen men, including Connant and Garry, are revealed to be Things. The remaining men go to test the isolated Blair, and on the way, see the first albatross of the Antarctic spring flying overhead; they shoot the bird to prevent a Thing from infecting it and flying to civilization.
When they reach Blair’s cabin, they discover that he is a Thing. They realize that it has been left to its own devices for a week, coming and going as it pleased, as it is able to squeeze under doors by transforming itself. With the creatures inside the base destroyed, McReady and two others enter the cabin to kill the Thing that was once Blair. McReady forces it out into the snow and destroys it with a blowtorch. Afterwards, the trio discover that the Thing was dangerously close to finishing the construction of a nuclear-powered anti-gravity device that would have allowed it to escape to the outside world.

Scientists are uncovering bizarre exoplanets that challenge everything we know about habitability. From super-Earths with crushing gravity to tidally locked planets with scorching hot and frozen hemispheres, these extreme worlds could give rise to lifeforms unlike anything on Earth. In this video, we explore the scientific possibilities of extraterrestrial life—how gravity, atmosphere, and star types could shape truly alien evolution. Could we find snake-like creatures on high-gravity worlds, black-leaved plants around red dwarf stars, or ocean-dwelling bioluminescent life on Europa-like moons? The possibilities are endless, and the science is fascinating!
