Citizen Scientist Finds Ancient White Dwarf Star Encircled by Puzzling Rings
A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf -- an Earth-sized remnant of a Sun-like star that has died -- ringed by dust and debris. Astronomers suspect this...
Multiverse Predictions for Habitability: Number of Habitable Planets
How good is our universe at making habitable planets? The answer to this depends on which factors are important for life: Does a planet need to be Earth mass? Does it need to be inside the temperate zone?...
A New Level 3 Biosafety and Astrobiology Laboratory in Pieve a Nievole (PT)
We report our proposal for the establishment of a biocontainment and astrobiology laboratory in a strategic area of Pieve a Nievole (PT) at 28 mt above sea level - to face the lack of biological and astrobiological research centers and...

Mission on the Moon - Program a classmate to complete a mission on the Moon | Teach with space PR38
Subjects: Computing, Mathematics, Arts |
This activity will introduce students to logical thinking by planning, testing and executing a simple mission on the Moon. Students will work in pairs and take it in turns to play the roles of “mission controller” and “rover”. One student will give commands to enable the other to navigate blindly across the lunar surface. They will have to follow a set route to avoid obstacles, carry out missions and arrive safely at their final destination.
What to expect when Hayabusa2 collects a sample from Ryugu
More than 4 years after launch and a half year surveying asteroid Ryugu, Japan's Hayabusa2 spacecraft is ready for sample collection.
Moon Rover - Building a solar-powered rover | Teach with space PR36
Subjects: Science, Physics, Arts |
In this activity, students will compare the advantages and disadvantages of renewable energy sources and non-renewable energy sources and study simple electrical circuits. Using the Moon as context students will build a small Moon rover powered by solar energy, using a small motor and a solar cell. They will also identify the main features their rover must have to go to the Moon and improve their initial rover design.
