What 600 days in space does to living cells The BIOlogy and Mars EXperiment (BIOMEX) project used Chroococcidiopsis sp., a rock-inhabiting microorganism found in sandstone from the Negev Desert, to study how life might survive on the Moon. Find out why.

Another study testing the limits of life in space, this time on the moon! #moon #lifeinspace #humanspaceflight #NASA #cyanobacteria #astrobiology

What underwater volcanoes can teach us about Saturn’s moon Studying underwater volcanoes called "hydrothermal vents" at the bottom of the ocean taught us that the hydrogen down there probably isn't a primary food source for life in this extreme environment.

How can we study far away plants using Earth environments? By looking at the bottom of the ocean! #hydrogen #hydrothermalvents #astrobiology

Is there life on Venus? An international team of researchers claim that a molecule called phosphine is a potential marker for life, and also happens to be in the atmosphere of Venus, according to their measurements. Other scientists are re-analyzing the results.

In September, a research group broke the internet when they said they discovered a molecule called phosphine in the atmosphere of Venus. We’ll try to break it down. #phosphine #venus #venuscloudlife

Is humanity ready to live in space? To live in space, we will need inter-generational cooperation to pull it off, and perhaps a sense of altruism for the future. We may be up to the technical challenge, but what about the sociopolitical challenges?

This article explores incentives for projects spanning millennia, and determines which of those incentives would provide the most successful approach.

How water shaped the Earth Minerologists, geologists, astronomers, astrobiologists explain how water shaped our planet’s history by studying the types of chemical reactions where water plays a fundamental role.

Water has molded our planet into what it is today, in ways you may not have imagined! #water #waterislife

Students inspired to study science by participating in real NASA missions In Rio de Janeiro, Brazil, a group of scientists and teachers came together to create an exciting new educational resource, named Ad Astra Academy. The goal? To develop brief, intense programs to help encourage academically at-risk students to develop critical thinking skills.

Can teachers get students in underrepresented, disadvantaged communities to feel excited about science if they get to participate in real NASA missions? Turns out, probably! #teaching #StemEd

Bread yeast can help humans explore space! Studying the effects of radiation on yeast cells can help us understand how astronauts’ bodies may be affected during long term space travel. This paper describes an experiment that will be conducted on board the satellite BioSentinel.

How do we find the effects of extreme #space radiation on human health? Answer lies with yeast in your bread! @NASA scientists are launching #BioSentinel later this year. #Astrobiology By @strayologist

Chemicals on mineral surfaces may have jumpstarted life Researchers observed selected biological molecules multiplying and fueling their own chemistry across mineral surfaces, resembling the patterns of a living metabolism.

Were metabolic pathways established before life emerged? New experiments observe life-like patterns self-propagating on #mineral surfaces. #astrobiology #geobiology

Algae in space teaches us how life responds to harsh environments A species of blue-green algae that can live in rocks could resist radiation and extreme space weather, and returned to Earth still viable!

Extremophiles can literally survive in many conditions, even in the extreme radiation of space. Read this article to learn how extremophiles help us understand the search for life in the universe.

Could a deadly gas be a sign of life? The presence of carbon monoxide on exoplanets is no longer a reason to discount the possibility of the presence of life.

How do scientists look for life in the universe? Usually they look for gasses that would support life, and assume anything toxic to us would be toxic to life. Perhaps that isn’t true across the board.
