Largest treasure trove of exocomets to date found in alien solar system

Thirty alien comets have been spotted transiting the young star Beta Pictoris, their long tails lighting up the skies of the fledgling planets forming there.

The comet discovery has been made using NASA’s Transiting Exoplanet Survey Satellite (TESS), which watches for dips in starlight as planetary bodies pass in front of — or transit — their star. Beta Pictoris, which is 63.4 light years away, is home to a dusty planet-forming disk that was discovered back in 1983 by IRAS, the Infrared Astronomy Satellite. The disk contains at least two planets, both gas giants, and spectral observations gathered as long ago as 1987 suggested evidence for comets (or ‘falling evaporating bodies’ as they were referred to at the time) releasing dust and gas into the disk.
