Are Texas Blackouts a Warning About the Follow-on Effects of Climate Change?

This week in America, “continent-spanning winter storms triggered blackouts in Texas, Oklahoma, Mississippi and several other states,” reports the New York Times. But that was just the beginning… One-third of oil production in the nation was halted. Drinking-water systems in Ohio were knocked offline. Road networks nationwide were paralyzed and vaccination efforts in 20 states were disrupted. The crisis carries a…

Curiosity rover spots signs of ancient megafloods on Mars

We already know that Gale Crater on Mars used to hold a lake or series of lakes a few billion years ago. Now, NASA’s Curiosity rover has found evidence for ancient giant floods that washed through the region as well. Source: https://earthsky.org/space/megafloods-gale-crater-mars-life-curiosity-rover…

Is Mars still volcanically active?

A new study of geologically young lava flows in Elysium Planitia suggests that Mars might still have residual volcanic activity below its surface. The finding could also correlate with seismic activity detected by the InSight lander in the same region and may have implications for possible martian life.

Field geology at Mars’ equator points to ancient megaflood

Floods of unimaginable magnitude once washed through Gale Crater on Mars’ equator around 4 billion years ago—a finding that hints at the possibility that life may have existed there, according to data collected by NASA’s Curiosity rover and analyzed in joint project by scientists from Jackson State University, Cornell University, the Jet Propulsion Laboratory and the University of Hawaii.

Year’s closest new moon October 16

October 16 brings us the closest new moon of 2020. Some will call it a supermoon. You won’t see this extra-close new moon because it’ll travel across the daytime sky with the sun. But you might see its gravitational effect on the tides along ocean shorelines in the days following new moon. Source: https://earthsky.org/tonight/years-closest-new-moon-october-16…
