The Perseid meteor shower: What you need to know



The Tarantula Nebula, also known as 30 Doradus or NGC 2070, measures a thousand light years across. It
features a high concentration of massive stars, which allows astronomers to further explore the formation
of such celestial bodies. This image was taken using the 1.5 m Danish telescope at the ESO La Silla
Observatory in Chile. ( R. Gendler, C.C. Thöne, C. Féron, and J.-E. Ovaldsen | Wikimedia Commons )

A research team at Chile's Very Large Telescope observatory has discovered more than a thousand massive stars.

The massive stars are 200 to 300 times larger than the Earth's Sun, a size range that astronomers previously considered to be impossible. The supergiant stars are found along the Tarantula Nebula or 30 Doradus, a star-forming region in the Large Magellanic Cloud galaxy where the largest and fastest stars have been observed. Its intense starburst activity has also been postulated to resemble that of the early Universe.

Massive stars have been known to exist but not in excessive numbers. They were believed to be rare as such stars lived shorter than their smaller counterparts.

In contrast, the Sun is estimated to be around 4.6 billion years old. It is expected to continue existing for another five billion years while supergiant stars have been theorized to last only for a few million.
