Scientists have retrieved samples from other objects in the Solar System, including comets and asteroids. What does it take to return a piece of rock from space, and what have we learned so far?
Today Travelers in the night take you to discuss about a pair of possibly related comets pass unusually close to Earth and a gentle method of causing an asteroid to miss planet Earth.
To night Travelers in the Sky tell you.a story about the developing equipment and skills to predict the impact of tiny space rocks. Also the discovery of very close approaching asteroids.
For decades, scientists have been trying to work out just how the Earth got all its water, and the prevailing theory was that comets and asteroids brought it, and we have evidence for that mechanic; however, a new hypothesis has provided evidence that the water was already here, locked away in hydrous minerals in a very iron-poor core.

A small space rock with a diameter less than the height of an NBA basketball player crossed the orbit of our Moon and nine hours after, it explode over Botswana. More at #365DaysOfAstro
After detecting high levels of organic matter using remote sensors at the asteroid Ryugu, numerical models show that it’s possible that rubble pile asteroids are actually extinct comets.
Using data from TESS, a new paper presents evidence for the discovery of thirty potential comets orbiting in the Beta Pictoris system.
