Observations of an asteroid group indicate that they may have metal-rich surfaces, but those asteroids with measured densities are about half as dense...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
The pressure and temperature conditions at which iron melts are important for rocky planets because they determine the size of the liquid metal core, an...
Ultra-low velocity zones sit beneath the central Pacific and Africa, atop the outer core of Earth. In these areas, seismic waves slow by as much as half,...
An analysis of the Hayabusa-2 sample of material returned to Earth from the carbon-rich, diamond-shaped, near-Earth asteroid Ryugu shows that the material...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have identified a dense, ultra-short-period sub-Earth planet transiting the bright,...
The Type Ia supernova remnant (SNR) G344.7-0.1 resides about 19,600 light-years away in the constellation of Scorpius.
This composite image shows SNR G344.7-0.1...
Astronomers have discovered a highly-irradiated gas giant exoplanet in close-in, highly misaligned orbit around a bright star called TOI-1518.
An artist’s...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
A rare iron mineral called santabarbaraite has never before been seen in a living organism, according to a paper to be published in the Proceedings of...
Astronomers using NASA’s Chandra X-ray Observatory have detected stable titanium, along with chromium and iron, blasting out from the center of the supernova...
The high-pressure magnetic phase observed in iron trithiohypophosphate, a 2D material that transitions from an insulator to a metal when compressed, likely...
Astronomers using the Space Telescope Imaging Spectrograph on the NASA/ESA Hubble Space Telescope have observed the main-belt asteroid (16) Psyche, the...
Astronomers using the High-Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W. M. Keck Observatory and the Canada-France-Hawaii Telescope...
Astronomers using the HARPS (High Accuracy Radial velocity Planet Searcher) spectrograph at ESO’s La Silla Observatory in Chile have detected gaseous...
A ferric mineral called hematite (Fe2O3) is present at high latitudes on the Moon, mostly associated with east- and equator-facing sides of topographic...
The inner core of our planet is between 1 and 1.3 billion years old, according to new research led by the University of Texas at Austin and Carnegie Institution...
An international team of scientists has found interstellar iron-60, a radioactive isotope with a half-life of 2.6 million years that is predominantly produced...
