  • by

Canopus, Alpha Carinae, is the brightest star in Carina constellation and the second brightest star in the night sky.

Canopus is fainter only than Sirius. The star is a supergiant or bright giant, yellowish-white in colour, with an apparent magnitude of -0.72. It is located at a distance of 310 light years from Earth. It lies too far south and can’t be seen north of latitude 37°18’N, but it is circumpolar for observers south of latitude 37°18’S.

For northern observers, Canopus doesn’t rise very high in the sky. The name Canopus comes from the Greek name Κάνωβος (Kanôbos), first recorded in Ptolemy’s Almagest (150 AD).

Eta Carinae

  • by

Eta Carinae is one of the most massive binary star systems known, lying at a distance of about 7,500 light years from Earth.

Eta Carinae is located in the direction of Carina constellation. The primary component in the system has about 90 times the mass of the Sun and is 5 million times more luminous.

The smaller star has about 30 solar masses and may be up to a million times more luminous than the Sun. Both stars will reach the end of their life cycle in supernova or hypernova explosions in the relatively near future.
