At the same time, he noted, there was still a 0.3% chance that their observation was a statistical fluke. “We need to be open and continue exploring other scenarios,” he added.
K2-18b is part of the “sub-Neptune” class of nearly 6,000 exoplanets that have been discovered beyond the solar system since the 1990s.
Finding evidence of life in the cosmos was the “holy grail” of exoplanet science, Madhusudhan said.
IN A NUTSHELL 🌌 Kokoro Hosogi, an undergraduate student, contributed to a groundbreaking study published in Nature. 🔭 The research utilized observations from the XRISM telescope to explore the dynamics of intergalactic gas. 💫 Discovery revealed the Centaurus cluster gas exhibits a wave-like motion, challenging existing models. 🎓 Hosogi’s involvement highlights the essential role of.
Good space battles can take many forms. They can be oversized, noisy fleet fights involving hundreds of ships or quiet and cerebral tests of wills between two solitary commanders. No matter the scale, great space combat always combines high stakes, clearly explained tactics and superior special effects.
This is the ultimate ranking of the best starship space battles in science fiction movies and television.
🔑 Space Battle Rankings:
1. Battlestar Galactica.
2. Star Trek: Deep Space Nine.
3. Star Wars Episode VI: Return of the Jedi.
4. Babylon 5
5. Star Trek II: The Wrath of Khan.

A study by researchers from the University of British Columbia’s Blusson Quantum Matter Institute (UBC Blusson QMI) has found a rare form of one-dimensional quantum magnetism in the metallic compound Ti4MnBi2, offering evidence into a phase space that has remained, until now, largely theoretical.
The study, published in Nature Materials, comes at a time of growing global interest in quantum materials that redefine the boundaries between magnetism, conductivity, and quantum coherence.
“We proved the existence of a new class of quantum materials that are both metallic and one-dimensional magnets, with strong coupling between the magnetic moments and their metallic host,” said UBC Blusson QMI Investigator Prof. Meigan Aronson.
In a future of limitless resources, what challenges remain when scarcity fades but human desires endure? Join us as we explore the path to post-scarcity civilizations, where technology solves material needs—but purpose, meaning, and new challenges await.

This is the first time that scientists have discovered a signal coming from a galaxy 9 billion light years from Earth.
The radio signal was detected by Pune, India’s giant VHF radio telescope.
The huge radio telescope is equipped with thirty parabolic antennas, each pointed skyward and with a diameter of about 45 meters.
In a first-ever near-infrared study of a recurrent nova beyond the Milky Way, astronomers have discovered exceptionally high temperatures and unexpect
WASHINGTON (Reuters) –In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest signs y
Astronomers have discovered a planet that orbits at a 90-degree angle around a rare pair of strange stars—a real-life ‘twist’ on the fictional twin suns of Star Wars hero Luke Skywalker’s home planet of Tatooine.
The exoplanet, named 2M1510 (AB) b, orbits a pair of young brown dwarfs —objects bigger than gas-giant planets but too small to be proper stars. Only the second pair of eclipsing brown dwarfs known—this is the first exoplanet found on a right-angled path to the orbit of its two host stars.
An international team of researchers led by the University of Birmingham made the surprise discovery using the European Southern Observatory’s Very Large Telescope (VLT). The brown dwarfs produce eclipses of one another, as seen from Earth, making them part of an “eclipsing binary.”
A pair of physicists at Universidad Nacional de Mar del Plata, in Argentina, have created a computer simulation of the famed Antikythera Mechanism and in so doing have found that manufacturing inaccuracies may have caused the device to jam so often it would have been very nearly unusable—if it was in the condition it is now. Esteban Szigety and Gustavo Arenas have posted a paper on the arXiv preprint server describing the factors that went into their simulation and what it showed.
In 1901, divers looking for sponges off the coast of the Greek island, Antikythera, discovered a mechanical device among the ruins of a sunken ship. The mysterious device was dated to the late second or early first century BCE, and from that time on there has been much debate in the scientific community regarding its purpose.
Some markings on the device suggest it could be used to track time and astronomical events and even predict some others, such as the arrival of a comet, courtesy of its intricate gears and pointing indicators, by turning its hand crank. Since only one of the devices has ever been found, some have suggested it had an otherworldly origin.
