Mather said finding one with lots of water - thought to be one of the key ingredients for life - would be "really interesting." As he put it: "a wet little planet out there that might be a little bit like home.The most popular questions about Webb. And that's one of our top goals - to see how stars grow, with their young planets," Mather said.Īn instrument called a spectrometer can study the atmospheres of exoplanets. "Infrared light will go around the dust grains instead of bouncing off, so we can see that with the Webb telescope. Until now, the dust in those clouds obscured the view. Mather said Webb can peer into the clouds of gas and dust where stars are being born. The goals also include observing the formation of stars and the planets around them. "We want to look at those first galaxies growing," Mather said. Its mission goals include searching for the first galaxies or luminous objects formed after the Big Bang and learning how galaxies evolved from their initial birth to the present day. We want to know: how did we get here from the Big Bang, how did that work? So, we'll look," said John Mather, Webb senior project scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "We're going to look at everything there is in the universe that we can see. After launch, it will deploy on a month-long million-mile (1.6 million km) journey to a more distant orbit than Hubble, beyond the moon. The telescope arrived in French Guiana in October after a 16-day sea journey from California through the Panama Canal to Port de Pariacabo on the Kourou River.
