At the Earth and Planets Laboratory, we work at the frontier of human knowledge. We discover new worlds, create new materials, illuminate the inner workings of our planet, and seek to understand the universe that is our home. In 2020 we merged the Department of Terrestrial Magnetism (est.1904) and the Geophysical Lab (est.1905) to create a new multidisciplinary department. By combining a century of scientific trailblazing, we are better suited than ever to collaborate, discover, and innovate.

New work led by Carnegie’s Peng Ni and Anat Shahar uncovers new details about our Solar System’s oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites.
An atom has a diameter of a fraction of a billionth of a meter. Earth’s diameter at the equator is about 12.7 million meters. The most distant object seen in Scott Sheppard’s continuing search for planet X orbits as far as 345 billion meters from the Sun. The research reported in this month’s newsletter covers these 21 orders of magnitude range in spatial scale.
