Gravitational Wave Detectors Spot Merging Black Holes That Have Merged Before
Two recent discoveries of black hole mergers add to the evidence that such mergers happen over and over again.

Mapping the Universe's Largest Objects
A team of scientists has released a new survey mapping massive galaxy clusters, some of the largest structures in the universe, to test whether our fundamental understanding of the laws of the universe need revision. The analysis, using six years of Dark Energy Survey data, addresses an ongoing debate about whether the universe has more structure than our best models predict, ultimately reinforcing that our current rules remain accurate while demonstrating that galaxy clusters provide a powerful independent method for probing the universe's deepest mysteries.
The Hidden Gas That Builds Stars
Astronomers have created the first large scale map of dark molecular gas in the Milky Way, revealing vast networks of invisible star forming material that have so far have remained undetected. Using the Green Bank Radio Telescope to observe faint signals from carbon, the research team has finally started to uncover one of astronomy's biggest mysteries. Their discovery uncovers turbulent flows of gas moving faster than expected and show how raw galactic matter transforms into the molecular clouds where stars are born.
Building Homes Beyond Earth
A new study has reviewed how space habitat designs have evolved from inflatable bubbles to 3D-printed structures built from Martian dust. The research traces how engineers have wrestled with extreme temperatures, the bombardment of radiation, and the challenge of building on worlds without breathable air, transforming each obstacle into solved problems with innovative ideas and designs that could soon house the first permanent residents of the Moon and Mars.

Spying Interstellar Comet 3I/ATLAS Near Perihelion
Everyone’s favorite interstellar comet 3I/ATLAS isn’t really hiding near perihelion this week, as amateur astronomers reveal. Don’t believe the breathless ballyhoo that you’re currently reading around the web about interstellar Comet 3I/ATLAS. In a clockwork Universe, comets are the big wildcard, and interstellar comets doubly so. This particular comet is scientifically interesting enough in its own right, no alien interlopers needed.

Many Asteroid Rotations Are Chaotic. A New Model Helps Explain Them.
Asteroids spin. Most of them do so rather slowly, and up until now most theories of asteroid rotation have failed to explain exactly why. A new paper from Wen-Han Zhou at the University of Tokyo and his co-authors might finally be able to fully explain that mystery as well as a few others related to asteroid rotation. Their work was presented at the Joint Meeting of the Europlanet Science Congress and the American Astronomical Society’s Division for Planetary Science in late September and could impact our understanding of how best to defend against a potentially hazardous asteroid.
Spectral Biosignatures of Airborne Microbes in Planetary Atmospheres
Could scientists find life in the clouds of exoplanet atmospheres? This is what a recently submitted manuscript hopes to address as a team of researchers investigated how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds. This study has the potential to help scientists develop new methods for finding life on exoplanets, either as we know it or even as we don’t know it.
Scientists Discover Ingredients for Life Just Beyond our Galaxy
A team led by a University of Maryland astronomer detected large complex organic molecules in ices outside of the Milky Way for the first time, offering a glimpse into the chemistry of the early universe.
