The sun launched back-to-back solar flares directly at Earth this week, but the geomagnetic storms pose little danger, officials said.
11 September 2014, 06:01 PM ET
Sunspot AR2158 produced a X1.6-class flare on September 10th, 2014. The site of the blast faced where Earth would be if a coronal mass ejection (CME) was emitted. Imagery not yet fully returned from orbiting observatories will be checked for this.

Solar flares are powerful blasts of radiation unleashed by the sun. When aimed directly at Earth, these eruptions can trigger geomagnetic storms and knock out power grids and communications. Here are some spectacular photos of solar flares.

The sun fired off strong flares Tuesday and Wednesday from a sunspot known as Active Region 2158, which will be the focus of a free webcast hosted today at 1 p.m. EDT by the online Slooh Community Observatory. Watch it here on Space.com.

Are you ready to capture the "supermoon" tonight? This evening, the moon will be at its best — in its full phase and at its closest point to Earth. If you have got a camera ready, it's a prime opportunity to capture a brilliant lunar spectacle.

Big slabs of ice are sliding over and under each other within Europa's ice shell, a new study suggests. The Jovian satellite may thus be the only solar system body besides Earth to possess an active system of plate tectonics.
