The search engine giant is rushing into the space after the bot ChatGPT caught the imagination of web users around the world with its ability to generate essays, speeches and even exam papers in seconds.

Microsoft has announced a multibillion-dollar partnership with ChatGPT maker OpenAI and unveiled new products on Tuesday, while Google tried to steal the march a day earlier by announcing its "Bard" alternative.

The bots are quickly being integrated into search engines and Google is battling to preserve its two-decade dominance of the web search industry.

But astronomers on Twitter quickly noticed that Google's Bard had given out an error in an ad on Twitter touting its new technology.

In the ad, the bot was asked about what to tell a nine-year-old about discoveries from the James Webb Space Telescope.

It incorrectly offered the response that the telescope was the first to take pictures of a planet outside Earth's solar system, when that honor actually belongs to the European Very Large Telescope.

The mess-up sent the share price spiraling down by more than seven percent on Wednesday with investors also underwhelmed by the latest announcements.
