The Milky Way’s 2 biggest satellite galaxies are oddly lonely, study finds

NeRD

The Milky Way’s system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found.  The Satellites Around Galactic Analogs (SAGA) survey is being conducted by a small group of astronomers to learn how the Milky Way and its little retinue of dwarf satellite galaxies compares to other galaxy systems. “The Milky Way’s satellite population is a unique combination of small satellites containing only older stars, and its two largest satellites, which are actively forming new stars,” says Marla Geha,…

Heart tissues beat half as strongly on the ISS as they do on Earth

NeRD

What effects does spaceflight have on an astronaut’s heart? This is exactly the question that prompted scientists from Johns Hopkins University to send 48 bioengineered heart tissue samples to the International Space Station, where they were monitored for 30 days and compared to identical samples on Earth. The team examined how low gravity impacts things like the cells’ strength of contraction, known as twitch forces, and any irregular beating patterns.  The results were concerning — the scientists found that heart cells “really don’t fare well in space,” beating with about…

NASA Seeks Innovators for Lunar Waste Competition 

NeRD

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) By Savannah Bullard  A new NASA competition, the LunaRecycle Challenge, is open and offering $3 million in prizes for innovations in recycling material waste on deep space missions.  As NASA continues efforts toward long-duration human space travel, including building a sustained human presence on the Moon through its Artemis missions, the agency needs novel solutions for processing inorganic waste streams like food packaging, discarded clothing, and science experiment materials. While previous efforts focused on the reduction of trash mass…

Van Gogh’s ‘Starry Night’ surprisingly adheres to the laws of physics, scientists find

NeRD

Vincent van Gogh’s “The Starry Night” is undoubtedly one of the most famous paintings in the world, instantly recognizable for its vibrant colors and dramatic brushstrokes that create what appears to be a sky in motion. But did you know that its night sky depiction actually follows the real laws of physics?  While the scene does take liberty in terms of what our eyes witness in the sky — we don’t necessarily see eddies dancing between the stars — scientists have determined those eddies indeed adhere to the laws of turbulent flow.…

Station Science Top News: Sept. 27, 2024

NeRD

Researchers found that long-duration spaceflight affected the mechanical properties of eye tissues, including reducing the stiffness of tissue around the eyeball. A better understanding of these changes could help researchers prevent, diagnose, and treat the vision impairment often seen in crew members. SANSORI, a Canadian Space Agency investigation, examined whether reduced stiffness of eye tissue contributes to vision impairment in astronauts on long-term missions. This condition, known as Spaceflight Associated Neuro-Ocular Syndrome, or SANS, includes a range of physical changes to the eyes. This paper suggests that biomechanical changes in the eye…
