At times mistaken for voracious and unrelated locusts, periodical cicadas are more annoying rather than causing biblical economic damage. They can hurt young trees and some fruit crops, but it’s not widespread and can be prevented.AP correspondent Julie Walker reports on cicada-geddon: two cicada broods that are about to infest the U.S.The largest geographic brood in the nation --

and coming out every 13 years -- is about to march through the Southeast, having already created countless boreholes in the red Georgia clay. It’s a sure sign of the coming cicada occupation. They emerge when the ground warms to 64 degrees (17.8 degrees Celsius), which is happening earlier than it used to because of, entomologists said. The bugs are brown at first but darken as they mature.

Soon after the insects appear in large numbers in Georgia and the rest of the Southeast, cicada cousins that come out every 17 years will inundate Illinois. They are“We’ll soon be left with just a dusty rubble pile,” astrophysicist Karl Battams with the U.S. Naval Research Laboratory said in an email.

Comets are balls of frozen gas and dust from billions of years ago. Every so often, a comet passes through the inner solar system.“These are relics from when the solar system first formed,” said Jason Ybarra, director of the West Virginia University Planetarium and Observatory.

The newest comet was discovered by amateur astronomers, who spied it in photos taken by a camera on a spacecraft operated by NASA and the European Space Agency to study the sun.The comet won’t swing close to Earth like Tsuchinshan-Atlas did last year. Other notable flybys included
