Regina G. Barber talks to Sarafina about three winter constellations, and journey through the life cycle of a star. Curious about the night sky?

Most stars are main sequence stars that fuse hydrogen to form helium in their cores - including our sun.

The Sun’s activity runs on a roughly 11-year cycle, with the star moving regularly from quiet to active and back to quiet. Those periods of activity are known as solar weather, and while their ...

Telling what is just regular activity and what is the beginning of a new phase of the star's life is inherently difficult for astronomers confined here to Earth.

The star was at the end of its life cycle when it profusely produced and expelled dust into space more than 4.6 billion years ago.

This summer, scientists have their eyes and telescopes trained on the small constellation system T Coronae Borealis. They think it will explode as part of a periodic nova — a once-in-a-lifetime ...

All stars exhibit some degree of variability; for example, the sun has an activity cycle that lasts around 11 years. During this cycle, sunspots on our star's surface increase and decrease in ...

They say the cycle’s peak will occur a year earlier in mid-late 2024 and sunspot numbers will be twice the official prediction – an indication of activity.
