The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets—Jupiter, Saturn, Uranus, and Neptune—extending as far as 30 times the distance between ...
Volatile elements, such as carbon, hydrogen, nitrogen and sulfur (S), are of profound importance for the formation, the differentiation and the habitability of a planet. However, today's Earth, though rich in life, contains ...
Thousands of alien worlds are known to orbit stars beyond our solar system. And many more worlds, possibly harboring life, lie waiting to be discovered. A new astronomical instrument called NEID, the NN-explore Exoplanet ...
Just as human beings and all other living things exist in a vast number of forms thanks to their genetic makeup, so different types of planets occur due to the chemical processes at work in the dusty regions surrounding newborn ...
Planets and their stars form from the same reservoir of nebular material and their chemical compositions should therefore be correlated but the observed compositions of planets do not match completely those of their central ...
Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type ...
In the early solar system, a "protoplanetary disk" of dust and gas rotated around the sun and eventually coalesced into the planets we know today.
Earth's vast habitats from the poles to the equator have robust capacity to remove carbon dioxide from the atmosphere due to previously undiscovered rock nitrogen weathering reactions that distribute natural fertilizers around ...
The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers involving scientists from the University of California, Davis, use data from meteorites ...
UNLV researchers and colleagues may have identified the first known planet to orbit three stars.
