In our discussions, we realized that a major bottleneck preventing the construction of more powerful telescopes is the challenge of making larger mirrors and getting them into orbit. In 2016, aerospace giant Northrop Grumman invited me and 14 other professors and NASA scientists – all experts on exoplanets and the search for extraterrestrial life – to Los Angeles to answer one question: What will exoplanet space telescopes look like in 50 years? These ambitious telescope projects are always expensive, laborious and produce a single powerful – but very specialized – observatory. The next flagship telescope is not expected to fly before 2045 and is estimated to cost $11 billion. The James Webb Space Telescope cost more than US$8 billion and took over 20 years to build. Even Webb is just barely powerful enough to search certain exoplanets for clues of life – namely gases in the atmosphere. However, it takes a lot more sensitivity to begin to learn about the chemical composition of these planets. Astronomers need to use giant space telescopes that collect huge amounts of light to study these faint and faraway objects.Įxisting telescopes can detect exoplanets as small as Earth.

Exoplanets, like TOI-700d shown in this artist’s conception, are planets beyond our solar system and are prime candidates in the search for life. Our proposed telescope, the Nautilus Space Observatory, would replace large, heavy mirrors with a novel, thin lens that is much lighter, cheaper and easier to produce than mirrored telescopes.īecause of these differences, it would be possible to launch many individual units into orbit and create a powerful network of telescopes. For the last seven years, I have been co-leading a team that is developing a new kind of space telescope that could collect a hundred times more light than the James Webb Space Telescope, the biggest space telescope ever built.Īlmost all space telescopes, including Hubble and Webb, collect light using mirrors. I am an astronomer who studies astrobiology and planets around distant stars. To find the answer, astronomers will likely need more powerful telescopes than exist today. The grand question is whether any of these planets are home to life. The European and Canadian space agencies joined NASA in building the powerful telescope.Astronomers have discovered more than 5,000 planets outside of the solar system to date. “We’ve really changed the understanding of our universe,” said European Space Agency Director General Josef Aschbacher. Webb’s use of the infrared light spectrum allows the telescope to see through the cosmic dust and “see light from faraway light from the corners of the universe”, he said. “Every image is a new discovery and each will give humanity a view of the humanity that we’ve never seen before,’’ NASA Administrator Bill Nelson said on Tuesday, speaking enthusiastically about the images showing “the formation of stars, devouring black holes”. ![]() But Webb’s sheer power, distant location off Earth and use of the infrared light spectrum showed them in a new light. With one exception, the latest images showed parts of the universe seen by other telescopes. The four additional photos released on Tuesday included more cosmic beauty shots. The first image from the $10bn James Webb Space Telescope was released on Monday at the White House - a jumble of distant galaxies that went deeper into the cosmos than humanity has ever seen. NASA has unveiled a new batch of images from its new powerful space telescope, including a foamy blue and orange shot of a dying star. ![]()
