...With an estimated mass of around 100 times that of Earth or 0.3 times the mass of Jupiter, TWA 7b is ten times lighter than any exoplanet previously directly imaged.

TWA 7b was discovered in the debris rings that surround the low-mass star CE Antilae, also known as TWA 7, located around 111 light-years from Earth.

From distant stars and galaxies to asteroids whizzing through the solar system, this next-generation facility unveils its first imagery and brings the night sky to life like never before

• First images: The first published images show the enormous diversity of objects that the Vera C. Rubin Observatory has captured in its images. The images are so large that no single screen is sufficient to display all the details. All images are available for download on the observatory's website.
• Comprehensive sky survey: The observatory will conduct a ten-year survey of the southern sky, investigating the influence of dark matter and dark energy on the distribution of galaxies in the universe, as well as variable phenomena such as supernovae and the flaring of galaxy cores when they swallow matter.
• Telescope of records: With an 8.4-metre telescope and the world's largest digital camera, the observatory captures large amounts of data.

I hope discussions are allowed in this community.

My idea is the following: if people ever set foot on Mars, they will need a continuous food source. It is preferable to be able to produce at least parts of that food on-site, instead of having to import it from Earth.

Now, i've thought about methane-eating bacteria or hydrogen-eating bacteria. They produce organic matter (and thus proteins) from anorganic ingredients (or ingredients that can be produced through technical processes like the Sabatier reaction). This way, anorganic ingredients (water extracted from the environment, hydrogen from electrolysis, CO2) can be turned into a source of proteins.

What do you think?

Is this technically viable?

Is it physiologically viable / healthy?

I'm well aware plants could also produce food. I just wanted to think about a possible alternative.
