Next time you’re swimming in the ocean, consider this: part of the water is older than the sun.
A huge arc of plasma has been imaged rising from the sun's surface by a NASA solar observatory, producing a beautiful view of the sun's magnetic dynamics in action. Continue reading →
Even though Mercury is one of the brightest objects in the sky, very few observers have ever seen the planet in the night sky. That's because it never strays very far from the sun, and is usually lost in its glare.
Over the past 24 hours, our planet's global magnetic field has been bombarded by two coronal mass ejections (CMEs) and now, as predicted, a "strong" geomagnetic storm is underway. Continue reading →
The first of two coronal mass ejections have slammed into Earth's magnetic field and space weather forecasters predict this rare one-two punch could result in 'supercharged' auroral displays. Continue reading →
Space weather forecasters have confirmed that Wednesday's solar flare also generated a coronal mass ejection that's now racing toward Earth. This is the second Earth-directed CME in two days. Continue reading →
At 1:46 p.m. ET (17:46 UT) on Wednesday, the sun reminded the solar system that it hasn't finished with solar maximum quite yet -- it unleashed a powerful solar flare and aimed it right at Earth. Continue reading →
The stellar nursery that produced our solar system separated out from the rest of the galaxy some 30 million years before the sun was born, new research shows.
