Bedtime Astronomy

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.

Artemis II marks humanity’s return to deep space after more than 50 years. Scheduled for April 1st, the mission will send a crew aboard NASA’s Space Launch System and Orion spacecraft on a lunar flyby, testing critical systems for future exploration. 

With a historic and diverse crew, this mission is a key step toward building a sustained human presence on the Moon—and eventually reaching Mars.

Meteorite hunters search remote deserts and polar regions for rocks that act as time capsules of the solar system.

Straddling science and commerce, these fragments reveal cosmic origins while fueling tension between research institutions and private collectors.

More than rare objects, they offer a direct physical link to a time before Earth existed.

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.
