Some Coronal Mass Ejections Are Caused By Shock Waves From Solar Flares In Other Regions Of The Sun

Summary:
Scientists have discovered that some CMEs are caused by solar flares not directly under them. Shock waves from the flares cross an interconnecting loop of solar material, causing it to eject hot X-rays that form a major part of the CME.

WASHINGTON - Scientists have discovered a new source for some of the large scale eruptions on the Sun known as coronal mass ejections, or CMEs. These eruptions are a key ingredient of strong geomagnetic storms that can cause bright auroras, damage sensitive satellite instruments in space, and even disrupt power generation and transmission by inducing strong electric currents below the surface of the Earth.

Nasa Gives You An Excuse to Post a Selfie on Earth Day

TheStreet (Apr. 22, 2014) NASA is inviting all social media users to take a selfie of themselves alongside nature and to post it to Twitter, Facebook, Flickr, Instagram, or Google Plus with the hashtag #globalselfie. NASA's goal is to crowd-source a collection of snapshots of the earth, ground-up, that will be used to create one "unique mosaic of the Blue Marble." This image will be available to all in May. Since this is probably one of the few times posting a selfie to Twitter won't be embarrassing, we suggest you give it a go for a good cause. Video provided by TheStreet
