Combining a quantum-inspired algorithm and quantum information processing technologies could enable researchers to measure masses of cosmic objects that bend light almost imperceptibly

Two recent discoveries of black hole mergers add to the evidence that such mergers happen over and over again.

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.

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.

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.

Albert H. Nagler, a pioneer of telescope optics, passed away at the office of his company Tele Vue Optics on Monday, October 27th. He was 90 years old.

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.

A nearly perfect alignment of factors has enabled Hurricane Melissa to become one of the most intense Atlantic storms ever recorded

In the 1970’s Vera Rubin didn’t set out to upend modern cosmology.
