A Dying Star Reveals What Will Happen to Our Sun

  Hidden in the center of the colorful swirl of gases is a dying star whose mass is approximately the mass of the Sun. With the aging of the stars, the nuclear reactions that sustain their brilliance begin to diminish. Unstable energy production causes the stars to pulse irregularly, ejecting their outer layers into space. This is how their super-hot core is revealed. It emits huge amounts of ultraviolet light. The radiation causes the gas layers to shine, creating something spectacular like the fragile beauty of the nebula.   The star of the image released by the European Space Agency...

The Sun

For thousands of years people have been looking at the sky and wondering what those objects are all about. The glittering stars and the Sun have always hid a certain amount of mystery and beauty. For astronomers, the Sun is just a dying star. For everyone else, however, it is a huge burning ball that gives us light, warmth and life. So far so good. But what really burns our Sun? It is a well-known fact that there is no air in the cosmos. Accordingly, there is no oxygen to burn. Our everyday experience tells us that burning is a...

Scientists Have Discovered the Cause of Solar Eruptions

For centuries, scientists have been puzzled by the gigantic and unpredictable outflows of plasma from the Sun, sometimes so aggressive that they can cause the glow of the Earth and disturb communications on our planet. But an international team of scientists think they may have finally identified the mechanisms that trigger these eruptions, and unlike previous theories, and small and large solar flares are caused by the same dramatic process. If the new hypothesis is correct, scientists may be able to predict eruptions, but also and when will cause damage on Earth. The researchers analyzed 3D simulations of two main...
