Probing the hydrothermal system of the Chicxulub impact crater

The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on Earth. International Ocean Discovery Program (IODP) and International Continental Scientific Drilling Program (ICDP) Expedition 364 drilled to a depth of 1335 m below the sea floor into the peak ring, providing a unique opportunity to study the thermal and chemical modification of Earth’s crust caused by the impact.

Barringer Medalist of Meteoritical Society Passes Away

Memorial, Bruce F. Bohor, the 2011 Barringer Medalist of the Meteoritical Society, passed away at this home in Gree Valley AZ on November 17, 2019. Bruce is best known in our community for his discovery of shocked quartz in layers of marking the Cretaceous-Tertiary (K-T, now called the Cretaceous-Paleogene, K-Pg) boundary in the central United States in the early 1980s following the famous paper by Alvarez and co-authors in Science in 1980, in which they report geochemical evidence for an asterioid impact from K-Pg boundary in Italy.

Will Artificial Meteor Showers be the future of Fireworks?

Can you imagine multi-colored meteor showers timed for your city event or national holiday? This company has developed this concept. From an article from ScienceTimes.com: Japan’s first big Artificial Meteor Shower Show was delayed due to technical challenges. The Astro Live Experiences-2 (ALE-2) satellite of a Tokyo-based company was launched to the Earth's orbit in December 2019 atop a Rocket Lab Electron booster. Initially, they planned to create meteor shows at special events for thousands of people to see.

Arizona is making a vital contribution to space exploration

… Today, both Arizona State University and the University of Arizona contribute hugely to space exploration, and the state is also home to a number of private companies heavily involved in the field. The unique qualities of the Arizona landscape also make it a natural home for some of the world’s leading observatories, as well as ongoing training and research around [Barringer] Meteor Crater and elsewhere.

The hunt for asteroid impacts on the moon heats up with new observatory

Sometimes a flash in the night is actually an asteroid slamming into the moon. Because such impacts offer valuable information about Earth's own barrage of space rocks, scientists have established programs that look for the brief bright flashes on the moon that represent lunar impacts. A new such telescope recently began operations, confirming observations of another telescope's 100th impact flash detection.

Watch for Lyrid Meteor Showers THIS WEEK, from home!

while stuck at home you may be able to witness the Lyrid Meteor Showers -  In a dark sky, you might see about 10 to 15 meteors per hour at the shower’s peak. But the Lyrids are always welcome, a break from the “meteor drought” that always comes in the early part of every year. In 2020, the skinny and almost-new moon won’t hinder the view. Bring on the Lyrids!
