Research may solve Moon’s volcanic fire-fountain mystery

© Afrim Constantin –

Some regions of the Moon exhibit dark mantling deposits that were formed by fire-fountain style eruptions, similar to Strombolian or some Hawaiian eruptions. This image is centered on a small impact crater (~170 meters in diameter) located within a larger regional pyroclastic deposit (5.470°N, 352.014°E) south of Sinus Aestuum. Since the crater has excavated fresh

NASA Begins to Build Satellite Mission to Improve Hurricane Forecasting

© Afrim Constantin –

Ten years after Hurricane Katrina formed in the Atlantic, assembly of NASA’s next-generation hurricane-observing satellite mission now is underway in Texas. NASA’s CYGNSS mission, a group of 8 microsatellites, will improve hurricane forecasting by doing measurements of marine surface winds in and near the eye wall of tropical typhoons, hurricanes and cyclones throughout their life

Comet impacts may have led to life on Earth — and perhaps elsewhere

© Afrim Constantin –

Dr. Koichi Mimura, from Nagoya University and Dr. Haruna Sugahara, from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Yokohama performed a sequence of experiments to mimic the conditions of comet collisions on the early Earth around 4 billion years ago, at the time when life first appeared. They took frozen mixtures of

See the return of the Andromeda Galaxy

© Afrim Constantin –

This picture of the Andromeda Galaxy, Messier 31, also shows its satellite galaxies, Messier 110 (top) and Messier 32 (lower right of M31’s nucleus). Dust lanes among the spiral arms of M31 can be seen in large unprofessional instruments, but the bright nucleus, M32 and M110 are easy objectives for little telescopes. A 65mm f/6.5
