A Prolonged Period of Something
Iceland’s volcanoes have been busy the past few months. If you remember 2010, a mostly quiet volcano named Eyjafjallajökull showed signs of eruption well ahead of its actual event, but no one except geologists, volcanologists and Icelanders really took it seriously until it happened. Eyjafjallajökull lies 25 km (16 mi) west of another subglacial volcano, Katla, under […]
If Wacky Weather Is Bad Now, Wait A Minute
This is regarding weather, CMEs, solar events, volcanoes, and our dependence on “other” for everything we need. Solar eruptions. Coronal mass ejections a/k/a CMEs. These are damaging and dangerous events that have occurred with our central star in the past. Could this happen again? Considering that when the Sun went dormant in 2006, and has had […]
Non-green Plants on Extrasolar Planets
Autumn foliage colors throughout the year? Many science fiction films depict foliation as being green. However, studies on plants have shown that the nature of the sunlight that reaches a plant influences that plant’s color. On earth, for example, plants photosynthesize mostly on red and on blue light. They also use some of the green […]
Large “Potentially Hazardous” Asteroid NASA Has Been Tracking for 22 Years Will Fly Past Earth Today
Near-Earth Object. Credit: NASA/JPL-Caltech The large near-Earth object is well known to astronomers and will get no closer than 3.9 million miles to our planet. A large near-Earth asteroid will safely pass by our planet on Wednesday morning, providing astronomers with an exceptional opportunity to study the 1.5-mile-wide (2-kilometer-wide) object in great detail. The asteroid, […]
Those Confounded Lights In the Sky – Again!!
Used to be that, if there were lights in the night sky, it was in a V-formation and was pooh-poohed as being migrating geese or something similar. And people were sure it was space aliens leaving Earth. Now, it’s Elon Musk and his project to put something on the order of 50,000 or more communications […]
Hubble Looks at Stunning Spiral Galaxy
This Hubble image shows a spiral galaxy called NGC 4100. Image credit: NASA / ESA / Hubble / L. Ho. Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking new photo of the spiral galaxy NGC 4100. NGC 4100 is located some 67 million light-years away in the constellation of Ursa Major. Also […]
Kepler space telescope- another find
Exoplanet illustration (furnished by NASA). After nine years in deep space collecting data that revealed our night sky is filled with billions of hidden planets– more planets even than stars– NASA’s Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe […]
