Why Nasa's Roman telescope is our best bet to find life in the stars

Imagine pointing a telescope at the crowded heart of the Milky Way and asking it to keep watching, not for hours or days, but for years. Every tiny flicker, movement or change in the light of hundreds of millions of stars could potentially tell astronomers that something is there: a new planet, a wandering world, a distant black hole or perhaps an Earth-like planet hidden among the stars.That is the promise of Nasa’s newest space observatory, the Nancy Grace Roman Space Telescope.Roman was launched on August 30 aboard a SpaceX Falcon Heavy rocket from Nasa’s Kennedy Space Center in Florida. The telescope is now on its journey to its destination nearly 1 million miles from Earth, where it will spend years surveying the universe.And there is already plenty of excitement around it.
