Telescope Arrays and Hunt for Exoplanets

The vastness of the universe ensures that our search for otherworldly neighbors is never-ending. One of the pioneering methods in this quest is the use of telescope arrays, especially when hunting for exoplanets - planets located outside our solar system.

How Do Telescope Arrays Work?

In essence, a telescope array consists of multiple telescopes working together as a single unit. By capturing and combining light from different sources, these arrays achieve a resolution that a single telescope, regardless of its size, could never accomplish on its own. This enhanced resolution allows astronomers to spot faint planets orbiting distant stars.

Prominent Telescope Arrays in Exoplanet Research

1. The Very Large Telescope (VLT): Located in Chile, the VLT consists of four telescopes that can work in tandem to study the universe. It has been instrumental in confirming the existence of several exoplanets.

2. The Kepler Space Telescope: While not an array, Kepler's contribution to exoplanet research cannot be overlooked. Its sole mission was to search for Earth-like planets in the habitable zones of their stars.

3. The upcoming Extremely Large Telescope (ELT): Touted to be the world's biggest eye on the sky, the ELT aims to make groundbreaking discoveries in the realm of exoplanets.
