Front

What is solar wind?

Back

Solar wind is a stream of charged particles released from the upper atmosphere of the Sun, known as the corona.

Front

What are blue stars known for?

Back

Blue stars are the hottest type of stars, with surface temperatures exceeding 10,000 degrees Celsius.

Front

What is the convective zone of the Sun?

Back

The convective zone is the layer of the Sun where hot gas rises, cools as it nears the surface, and then sinks back down.

Front

What is the difference between a protostar and a star?

Back

A protostar is an early stage in star formation, where gas and dust are collapsing under gravity, while a star is a fully formed celestial body that undergoes nuclear fusion.

Front

What are solar flares?

Back

Solar flares are sudden eruptions of energy on the Sun's surface, releasing a large amount of radiation.

Front

What is a supernova?

Back

A supernova is a powerful and luminous explosion that occurs at the end of a star's life cycle.

Front

What is the chromosphere?

Back

The chromosphere is a layer of the Sun's atmosphere located above the photosphere and below the corona.

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas, caused by magnetic activity.
