A geomagnetic storm may be on its way this weekend, and it could be dazzling. Forecasters at NOAA's Space Weather Prediction Center say there is a good chance that there will be a geomagnetic storm, or a disturbance in the Earth's magnetic field, this weekend after the solar flare that erupted on the sun Thursday morning. Although Thursday's solar flare was the biggest yet in 2013, it was classified as a mid-level flare. It was still strong enough to cause a brief radio blackout NASA said.

A defunct NASA satellite, whose doomed descent gained worldwide notoriety, fell back to Earth early Saturday — but exactly when or where the fiery plunge took place could forever be a mystery. "We may never know," said Nicholas Johnson, NASA's chief orbital debris scientist. It probably plunged into the Pacific Ocean, perhaps somewhere between Hawaii and the western coast of North America. There have been no reports of discovered pieces or injuries, further suggesting the debris didn't make it to land, he said.

In response to Lee Dye's article "Galileo Views Earth With an Alien's Eye" (front page, Dec. 20): In light of all the endless conflicts between men across our planet, Galileo, the spacecraft, seems to have discerned the root of the problem--"it detected no clear sign of intelligent life" on planet Earth!

Larry Stammer's report from London, "Saving the Earth: Who Sacrifices?" (Part I, March 13) and the editorial "A Truce With Nature" on the same day give a dire prognosis on the state of the Earth's health. Hopefully, such information will help arouse the consciousness of people as to the sacrifices it will be necessary for us all to make if we are to survive. I wonder, do we stand by and watch our magnificent planet and all the life it holds being destroyed in the same manner we have allowed the continuation of the building of nuclear weapons, spending billions and billions of dollars each year while people starve and our Earth suffers?

"Stop the world, I want to get off" is an old refrain, but what if it actually happened? The consequences for life as we know it are considered in the new special "Aftermath: When the Earth Stops Spinning." (National Geographic, 6 and 9 p.m. Mon.)

The meek shall inherit the Earth, and that may not be a good thing, if the meek are cyanobacteria. It turns out that the ancient microbes lowest on Earth's food chain are sensitive sorts. Familiar strains of these organisms that provide "biological services" essential to complex life are about to lose the competition for a viable niche in a world turned warmer and more carbon-rich, according to two new studies. And the strains poised to dominate in the desert and ocean remain mysterious and largely unstudied.

This stunning image of the Earth, claimed to be the highest-resolution image of the planet taken from space, was produced by the Russian weather satellite Elektro-L. The camera on board the satellite has a reported resolution of 121 megapixels, about 15 times the number in an iPhone. The image was produced by overlaying images taken at three wavelengths of visible light and one in the infrared, producing the color spectrum observed. The infrared image shows vegetation, which appears orange.
