What if Earth had rings? (disk weather)

EXCERPT: What might Earth be like crowned with rings? Space and science-fiction illustrator Ron Miller created extraordinary images of how the sky might look if Earth possessed rings of the same proportions to our planet as Saturn's are to it. The most stable place for rings is around a planet's equator, so the appearance of the rings would vary by latitude... (MORE - images)
Zombie storms are rising from the dead thanks to climate change

EXCERPTS: Wildfires are burning the West Coast, hurricanes are flooding the Southeast — and some of those storms are rising from the dead. "Zombie storms," which regain strength after initially petering out, are the newest addition to the year 2020. And these undead weather anomalies are becoming more common thanks to climate change.
[...] There has been an "extreme amount of heating of the Gulf (of Mexico), particularly in some of the ocean areas off of the Carribean," Donald Wuebbles told Live Science. The Gulf of Mexico, where many hurricanes gain strength before hitting the U.S., is particularly vulnerable to global warming because the gulf waters are very shallow — and thus heat up easily, Wuebbles said...

Meteors that brushed Earth's atmosphere may have brought life to Venus, study says

INTRO: Earlier this month, researchers discovered traces of phosphine in the clouds of Venus, a molecule that is only made on Earth as a byproduct of life. A new study, suggests the phosphine may have emanated from our planet. The research, from the Department of Astronomy at Harvard University, suggests that asteroids that have grazed Earth's atmosphere in the past — believed to be at least 600,000 — might have scraped microbes that live in the atmosphere and brought them to the second planet in the Solar System.
"Although the abundance of terrestrial life in the upper atmosphere is unknown, these planet-grazing shepherds could have potentially been capable of transferring microbial life between the atmospheres of Earth and Venus," the researchers, Amir Siraj and Abraham Loeb, wrote in the study's abstract. "As a result, the origin of possible Venusian life may be fundamentally indistinguishable from that of terrestrial life."
The research, which has not yet been peer-reviewed, has been published on the pre-print arXiv server... (MORE)
