Planetary Seeds

One of the greatest challenges in science is understand how the solar system formed, specially how the planets —including Earth— formed. Answers about it are no easy, but a reliable path is to see other planetary systems in the making, their light offer important clues to scientists.

Indeed, few weeks ago two teams —one of them leaded by astronomers from Mexico and Spain— published observational results made with a 27-antennas array in New Mexico, US, and a giant telescope settled in the Chilean desert. The former instrument detects radio emission and the last one infrared light coming from cosmic objects. The goal was to study a rare and very young system, one that probably looks like our solar system, but 4 billion years ago.

Ones upon a time…

Regardless the enormous distances in the Cosmos, young stars always born embedded in the densest parts of huge clouds of gas and dust. Unfortunately, its detection and study is practically impossible with telescopes that catch the same light as we perceive with our eyes. Thus, astronomers appeal to sensitive instruments in «other lights», such as infrared and radio waves.
