Mapping out meteorites in Antarctica: Uncovering our solar system's deep past

A Belgian-Dutch team of scientists has created the first-ever "treasure map" that shows where in Antarctica meteorites are likely to be found. Meteorites are chunks of stone-like material that can be found on the surface ...

Could the asteroid Ryugu be a remnant of an extinct comet?

Asteroids hold many clues about the formation and evolution of planets and their satellites. Understanding their history can, therefore, reveal much about our solar system. While observations made from a distance using electromagnetic ...

How NASA's Roman telescope could help find Earth-like planets by surveying space dust

A team of scientists found NASA's Nancy Grace Roman Space Telescope will be able to measure a specific kind of space dust littered throughout dozens of nearby planetary systems' habitable zones, or the regions around stars ...

Meteorites that helped form Earth may have formed in the outer solar system

Our solar system is believed to have formed from a cloud of gas and dust, the so-called solar nebula, which began to condense on itself gravitationally ~ 4.6 billion years ago. As this cloud contracted, it began to spin and ...

Asteroids are dangerous, but they might also be the key to life on Earth

Trying to piece together the appearance of life on Earth is a little like looking through a kaleidoscope. There are competing theories for where Earth's water came from, and there's incomplete evidence for how the moon formed ...
