The James Webb Space Telescope has made a lot of incredible discoveries, but not the one that a Google bot suggested yesterday (Feb. 8).
NASA’s James Webb Space Telescope (Webb or JWST) launched in December 2021 on a deep-space mission and became fully operational in July 2022. It’s been scanning the cosmos and catching all kinds of incredible things: an accidental find of a space rock or asteroid, the historic agency DART mission that deliberately crashed into another asteroid, and unprecedented views of galaxies and the early universe.
But Google’s hyped artificial intelligence (AI) chatbot, Bard, just attributed one discovery to Webb that was completely false. In a livestreamed event, blog post (opens in new tab) and tweet (opens in new tab) showing the test AI in a demo Tuesday, the chatbot was asked, “What new discoveries from the James Webb Space Telescope can I tell my nine-year-old about?”
The query came back with two correct responses about “green pea” galaxies and 13-billion-year-old galaxies, but it also included one whopping error: that Webb took the very first pictures of exoplanets, or planets outside the solar system. The timing of that mistake was off by about two decades.

The actual first image of an exoplanet was released (opens in new tab) back in 2004, according to NASA. The incredible sight was captured by a powerful ground observatory, actually: the Very Large Telescope, a flagship facility with the European Southern Observatory in Chile.
That exoplanet is called 2M1207b. It is orbiting a brown dwarf, which is an object that is larger than a planet but not quite large enough to produce nuclear fusion to shine like a star. The image was no small feat: the planet’s reflected light was imaged from 230 light-years away. (For perspective, the closest star system is about four light-years from us and yes, Alpha Centauri also has planets.)

The embarrassing error for Google caused the search giant’s parent company, Alphabet Inc., to lose $100 billion in market value Wednesday, according to Reuters (opens in new tab). Industry observers fear that Google is quickly losing credibility to rival bot creator OpenAI, a startup heavily supported by fellow search giant Microsoft (which produces Bing).
OpenAI’s ChatGPT was released in November 2022 and can produce remarkably human-like text, even in different writing styles. Just the day before Google’s blunder, in fact, Microsoft said there was a version of the Bing search available that has some of ChatGPT’s functions integrated.
That said, ChatGPT is not immune from error either. Last week, National Public Radio asked (opens in new tab) the bot to do some simple rocket science. It sounds like the result was worse than a beginner in the physics-inspired Kerbal Space Program game that trains folks how to launch rockets.
The bot was asked, for example, to produce a fundamental mathematical equation for rocket science called “the rocket equation.” When real-life rocket scientist Tiera Fletcher read the result, her laconic response to NPR was this: “It would not work. It’s just missing too many variables.”
