| In 2002, it was 107 to 109. But the country with the most remarkable record is that other supergiant, India. |
| A blue-white supergiant in the constellation Orion, Rigel is about 870 light-years from the Sun and is about 47,000 times as luminous. |
| The astronomers realised that a normal red supergiant alone could not have given rise to such a weird supernova. |
| The group of astronomers studied a sample of 74 red supergiant stars in the Milky Way. |
| It was suggested that the red supergiant orbited a companion star that had shredded its outer layers just before the explosion. |
| For several weeks, the red supergiant Star V838 Moncerotis was the most brilliant star in the Milky Way. |
