Astronomers have observed a distant galaxy dimming to just 5% of its original brightness in only two decades. The cause: a sudden drop in gas feeding its central supermassive black hole.

This discovery shows that active galactic nuclei can evolve on human timescales, challenging existing models and reshaping our understanding of black hole behavior.

A new AI system, RAVEN, is transforming how scientists discover exoplanets. Using four years of NASA TESS data, researchers confirmed 118 planets and flagged thousands more candidates with high precision.

By filtering out stellar noise, this approach improves our understanding of short-period planets and rare regions like the “Neptunian desert,” marking a major step toward automated, large-scale mapping of planetary systems.

New experiments at NASA Jet Propulsion Laboratory challenge the idea that life could form cell-like membranes on Titan.

Under simulated conditions, acrylonitrile failed to assemble into predicted “azotosomes,” instead forming stable crystals with liquid ethane.

The findings complicate theories of methane-based life, suggesting that if extraterrestrial biology exists, it may follow entirely different chemical architectures.

Scientists have identified all five nucleobases of the genetic code in pristine samples from the asteroid Ryugu, collected by the Hayabusa2.

The finding shows that the core components of DNA and RNA existed in space before life on Earth, supporting the idea that asteroids may have delivered the raw ingredients for biology.

The origin of life may be deeply rooted in cosmic chemistry.

Scientists are developing a closed-loop system to grow food on Mars using biology instead of Earth-supplied resources.

Cyanobacteria cultivated on Martian dust and atmospheric gases are processed via anaerobic fermentation into nutrient-rich fertilizer, enabling the growth of protein-dense duckweed. 

The system also produces methane as a usable energy byproduct. This dual-output approach—food and fuel—points toward scalable, self-sufficient agriculture for long-duration missions and permanent settlements beyond Earth.
