Astronomers are one step closer to understanding one of the most enduring solar mysteries, having captured unprecedented data from the sun's magnetic field. The groundbreaking data collected from the ...

Imagine for a minute that you have been transported to the middle layers of the sun’s atmosphere. The sun’s surface, the “visible disc” scientists call the photosphere, boils below you, red-hot plasma ...

The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades. One explanation is ...

Astronomers have finally unraveled the enigma of why the Sun’s outer atmosphere, known as the corona, is significantly hotter than its surface. While the Sun’s surface temperature is about 5,500 ...

Daniel Stanyer Augusta, Kansas First, let's discriminate between expansion and expulsion. Expansion happens because the thermal pressure from the increased energy production in the Sun's interior ...

How hot is the sun? Here are the scorching temperatures of the star's layers The sun provides energy that is vital for life on Earth, and that energy comes as a result of the sun’s heat. But how hot ...

Sunlight needs only a little over eight minutes to cross the space between the Sun and Earth. The energy behind it may already have spent around 170,000 years moving outward from the Sun’s core. That ...
