We might soon have the technology to reach other star systems
The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth.

Are Aliens Harvesting the Spin of Stars?
One of the challenges of searching for “technosignatures” (i.e. signs that intelligent life somewhere in the universe has created technology) is understanding what to look for. Technology is a very broad area, and different types would show up as different features. One of the most commonly cited is a Dyson sphere, which attempts to encapsulate a star and capture it’s outgoing light to produce energy. But while we’ve looked for the mid-infrared waste heat these structures would produce for decades, we haven’t found a definitive instance of one. According to a new paper, available in pre-print on arXiv by Turkish high school student Sahin Torlakcik, that might be because we are looking for the wrong type of energy all together.

In search of life beyond our solar system: Atmosphere detected on a habitable-zone rocky world
In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star. The finding provides the strongest evidence yet that worlds with conditions similar to Earth in composition and temperature, with the potential to support life, could exist beyond our solar system.

Astronomers find nearby planets to be small, strange, and utterly uninhabitable
Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard's Star—the sun's closest neighbor after Alpha Centauri, just under six light-years from Earth.

Alien world chemistry found inside meteorite that struck New Jersey home
On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time later, a meteorite weighing more than 2 pounds crashed through the roof of a house in the town of Hillsborough, New Jersey.
