The bright protostar T Tauri, situated 471 light-years away in the Taurus constellation, is expected to vanish from view for decades. This dimming phenomenon, triggered by a thick disk of gas and dust surrounding its companion stars, could last up to a century. Astronomers have been observing this system, comprising three growing stars, for decades due to its unpredictable brightness variations and significant role in understanding protostellar evolution. Great Dimming Expected in the T Tauri System According to research accepted by The Astronomical Journal, the disk encircling T Tauri South A and B is moving into a position where it will obscure T Tauri North, the only visible star of the trio. T Tauri North’s light has already dimmed significantly since 2016, with brightness levels dropping to magnitude 12 by 2022–2023. Dr Tracy Beck from the Space Telescope Science Institute stated in an American Astronomical Society press conference that this dimming could continue for approximately 100 years due to the stars’ relative motion. Unique Opportunity for Planetary Formation Studies As reported by space.com, the dimming …
