NEA Scout is composed of a small, shoebox-sized CubeSat (top left) and a thin, aluminum-coated solar sail about the size of a racquetball court (bottom left). After the spacecraft launches aboard Artemis I, the sail will use sunlight to propel the CubeSat to a small asteroid (as depicted in an illustration, right). Credit: NASA NEA […]
According to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the universe. Of the bodies on which life is possible, living organisms could most easily enter the other bodies of the Solar System from Enceladus.
New research has revealed that Earth was bombarded with ten times as many objects from space, like meteors and asteroids, as previously believed during its early history.
An atomic blast is not the preferred solution for planetary defense, but 3-D models are helping scientists prepare for a worst-case scenario.
According to data from NASA’s Center for Near-Earth Object Studies, the asteroid 2021 SM3, which was just discovered last month, will pass by our planet on Friday.
Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), a team of astronomers has obtained the sharpest and most detailed images yet of the asteroid Kleopatra.
The new theory suggests the troughs are something known as fault-bounded valleys
The asteroids may have originated from the vicinity of Neptune’s orbit.
The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 66 million years ago likely came from the outer half of the main asteroid belt, a region previously thought to produce few impactors.
The space rocks may have come from beyond Neptune, and potentially offer hints at the chaos of the early solar system.
