Research team studies kombucha cultures under simulated extraterrestrial conditions. An international research team including the University of Göttingen has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures – a symbiotic culture of bacteria and yeast. Although the simulated Martian environment destroyed the microbial ecology of the kombucha cultures, surprisingly, a cellulose-producing bacterial species survived. The results were published in Frontiers in Microbiology.

The scientists of the “Biology and Mars Experiment” (BIOMEX) project had already sent kombucha cultures to the International Space Statio...

An international team of scientists today released the largest near-infrared image ever taken by NASA’s Hubble Space Telescope, enabling astronomers to map the star-forming regions of the universe and learn how the earliest, most distant galaxies originated. Named 3D-DASH, this high-resolution survey will allow researchers to find rare objects and targets for follow-up observations with the recently launched James Webb Space Telescope (JWST) during its decades-long mission.

A preprint of the paper to be published in The Astrophysical Journal is available on arXiv.

“Since its launch more than 30 years ago, the Hubble Space Teles...

For the first time, researchers have created simulations that directly recreate the full life cycle of some of the largest collections of galaxies observed in the distant universe 11 billion years ago, reports a new study in Nature Astronomy.

Cosmological simulations are crucial to studying how the universe became the shape it is today, but many do not typically match what astronomers observe through te...

In a paper recently published in The Planetary Science Journal, NASA scientists and engineers give new details about the agency’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.

DAVINCI, a flying analytical chemistry laboratory, will measure critical aspects of Venus’s massive atmosphere-climate system for the first time, many of which have been measurement goals for Venus since the early 1980s...
