The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

The evidence from this data looks very clear: the core of the sun is rotating about once a week, instead of about once a month at the surface. This was a surprising, unexpected discovery.

"The most likely explanation is that this core rotation is left over from the period when the sun formed, some 4.6 billion years ago," said Roger Ulrich, from UCLA and co-author of the study.

The sun's core rotates nearly four times faster than the sun's surface, an international team of astronomers reports in the journal Astronomy & Astrophysics. The most likely explanation is that ...

Another blistering temperature comes from the sun's surface, which lingers at 10,340 degrees Fahrenheit.While it's cooler than the core, the surface is still extremely hot, and no human or animal ...

However, that is significantly colder than the current core of the sun, which is about 27 million degrees. At this point, the sun is like the smoldering ashes left behind from a fire, all but dead.

The core of the sun will become even denser and hotter. As this happens, the sun will swell one-and-a-half times its normal size and grow more than twice as bright as it is now.
