DART's journey to Dimorphos Illustration showing the size comparison between DART, Didymos and Dimorphos. DART site between a bus and the Arc De Triomphe in terms of size. Dimorphos is located between the Statue of Liberty and the Great Pyramid of Giza. While Didymos is between the One Wor...
During the announcement, NASA Administrator Bill Nelson put the image into perspective, saying, “If you held a grain of sand at the tip of your finger at arm’s length, that’s the part of the universe that you’re seeing—just one little speck of the universe.” The photo, which was...
A comparison of the position of each globe, particularly when viewed from above, helps to distinguish exophthalmos from buphthalmos. Resistance of the globe to retropulsion is also helpful to confirm exophthalmos. The direction of displacement of the globe can be helpful in localizing the site of...
Conversely, it would be a moot point if it takes a Chicxulub impactor size asteroid (∼10 km diameter) to create a basin-wide tsunami, since the expected tsunami casualties may pale in comparison to those from continent-scale firestorms and the following decade long global impact winter ...
the final stage of the crater’s formation, in which the transient crater collapses to form the final structure (see video). This allowed the researchers to make the first comparison between 3D Chicxulub crater simulations and the present-day structure of the crater revealed by geophysical data....
