A nova, literally a “new star,” is expected to light up in the Northern Crown constellation this year. The star has been around for a long time and is rarely seen with the naked eye. Author and natural scientist Christian Mähr found a monk who had already observed the nova – in the 13th century.
Regardless, the star “T Coronae Borealis” is still clearly visible in the telescope today. The system is located about 2,700 light-years away and consists of two stars, one very large and one very small. They orbit each other at half the distance between the Earth and the Sun.
The big one is a red giant, several times larger than our sun and ‘cooler’. Not 6000 degrees, but half or less. The small one represents the other extreme, a white dwarf. It has about the mass of the Sun, but is only as large as Earth. So it is quite “dense” – there are ten tons in one cubic centimeter! How can two stars so different be so close to each other?
