Astronomers studying stars like our sun that are known to generate powerful 'superflares' have also discovered that these superflares are likely associated with monster 'starspots.'
This beautiful portrait of our nearest star was captured by NASA's Solar Dynamics Observatory (SDO), picking out the powerful and elegant loops of magnetized plasma reaching high into the sun's corona.
Astronomers have taken a census of distant spiral galaxies to help us understand what our Milky Way may have looked like in the distant past, also providing us with an invaluable look at the evolution of our own solar system.
The primordial planet believed to have smashed into baby Earth, creating a cloud of debris that eventually formed into the moon, was chemically a near-match to Earth.
The most powerful solar storm of the current solar cycle is currently reverberating around the globe.
The sun has erupted with its first X-class solar flare of 2015, a not-so-subtle reminder that it can still muster the energy required to generate the most powerful class of solar explosion.
A new computer model of our sun's magnetic field suggests the shape of our solar system's heliosphere is stranger than we ever thought.
Our sun will not explode as a powerful supernova when it eventually runs out of fuel, but that doesn't mean there won't be fireworks.
