Hard Knocks in Tyrrhena Terra
This enhanced-color image shows a small portion of a dark crater floor in the Tyrrhena Terra region of Mars. This is largely ancient hard bedrock that has been cratered by numerous impacts over the eons. Two other interesting geological features in Tyrrhena Terra (not pictured here): Herschel Crater and Tyrrhena… Read more“Hard Knocks in Tyrrhena Terra”
Raining Rocks
Impact ejecta is material that is thrown up and out of the surface of a planet as a result of the impact of an meteorite, asteroid or comet. The material that was originally beneath the surface of the planet then rains down onto the environs of the newly formed… Read more“Raining Rocks”
NASA Makes an EPIC Update to Website for Daily Earth Pics
NASA has upgraded its website that provides daily views of the Earth from one million miles away. NASA’s Earth Polychromatic Imaging Camera (EPIC) camera imagery website was recently updated allowing the public to choose natural or enhanced color images of the Earth and even zoom into an area on the… Read more“NASA Makes an EPIC Update to Website for Daily Earth Pics”
Cosmic Lenses Support Findings on Accelerated Universe Expansion
The Hubble constant — the rate at which the Universe is expanding — is one of the fundamental quantities describing our Universe. A group of astronomers from the H0LiCOW collaboration, led by Sherry Suyu, Max Planck professor at the Technical University Munich (TUM) and the Max Planck Institute for Astrophysics… Read more“Cosmic Lenses Support Findings on Accelerated Universe Expansion”
Remembering Gene Cernan
Jan. 15, 2017 “We leave as we came, and, God willing, we shall return, with peace and hope for all mankind.” — Cernan’s closing words on leaving the moon at the end of Apollo 17 Eugene Cernan, the last man to walk on the moon, died Monday, Jan. 16, surrounded… Read more“Remembering Gene Cernan”
Well-Preserved Impact Ejecta on Mars
This image of a well-preserved unnamed elliptical crater in Terra Sabaea, is illustrative of the complexity of ejecta deposits forming as a by-product of the impact process that shapes much of the surface of Mars. Here we see a portion of the western ejecta deposits emanating from a 10-kilometer impact… Read more“Well-Preserved Impact Ejecta on Mars”
