How does life handle the harshness of space? Experiments on the International Space Station showed that lichens, a combination of algae and fungi, survived in space-like, flight, and Mars-like environments.

A new understanding of weather on Saturn The Cassini spacecraft revealed the atmosphere of Saturn has large regions that don’t cycle to the poles and that the atmosphere is filled with waves that disrupt circulation.

Long Space Flights Cause Fluid Build-up in the Brain On Earth, gravity moves the fluids in our body downward from our head to our feet. But, the lack of gravity in space can cause an increased fluid build-up in our head. Scientists have found that spending a long time in space expands the size and volume of fluid in the brain, leading to long-term health problems.

We can learn about life on other planets by studying viruses These scientists suggest that perhaps viruses were the first "life form" on Earth, a provocative idea!

Scientists from the University of Zurich and the Max Planck Institute for Molecular Genetics, as well as the Icahn School of Medicine at Mount Sinai have come together to summarize recent evidence has challenged our working theory on the origin READ MORE

Can Artificial Intelligence find new planets for us? Artificial intelligence could identify exoplanet signals faster in the data collected by NASA’s TESS mission.

On a clear night you might easily see Jupiter, Mars or other planets from our solar system. This is how astronomers from thousands of years ago discovered the first planets. We cannot directly observe planets that are farther out in READ MORE

Safety in Numbers: Bacterial Resistance in Space Bacterial cells were found to be more resistant to space hazards when grouped together as aggregates and could even protect secondary bacterial species.

Space is a dangerous place. Astronauts are wrapped up in layers of protection that regulate pressure, temperature, and oxygen. This protection has been developed through decades of medical research and testing, just to keep astronauts alive. The main space hazards READ MORE

What if the entire planet had it’s own flag? A scientist proposes that as we explore space, the Blue Marble flag should be used as a symbol for the citizens of Earth.

By Eric Moyer and Gina Riggio Blue Marble Space Young Scientist Program Since humanity’s first journey off the ground, advances in space exploration and aviation have been a fierce competition among nations on the international stage. Sanjoy Som writes in READ MORE

A crater on Mars may be a future landing site Rock formations on the Jezero Crater on Mars give us clues that there were probably active rivers there at some point.

Here on Earth, scientists study layers of sediment like dirt and sand to better understand how rocks form. The same contextual clues geologists use to explain how sedimentary rocks form on Earth can also be applied to extraterrestrial planets. Recent READ MORE

What happens if we send signals into space? Scientists explore potential risks of intentionally and unintentionally transmitting information into space

By Margareth Cheng-Campbell Blue Marble Space Institute of Science, Young Scientist Program For over a hundred years, humans on Earth have been using radio transmissions to communicate with each other. This ability to communicate around the globe has brought people READ MORE

Using The Big Bang As A Ruler Cosmologists use baryon acoustic oscillations to map distances as the universe expands

Baryon acoustic oscillations, an artifact remaining from the Big Bang, can be used by scientists to measure cosmological distances regardless of how the distances are changing. Soon after the Big Bang, the beginning of our universe, all of the matter READ MORE
