Betelgeuse: Nearby ‘supernova’ star’s dimming explained

Science
Astronomers say big cool patches on a "supergiant" star close to Earth were behind its surprise dimming last year.Red giant stars like Betelgeuse frequently undergo changes in brightness, but the drop to 40% of its normal value between October 2019 and April 2020 surprised astronomers.Researchers now say this was caused by gigantic cool areas similar to the sunspots seen on our own parent star.There had been speculation that Betelgeuse was about to go supernova.But the star instead began to recover and by May 2020 it was back at its original brightness.Betelgeuse, which is about 500 light-years from Earth, is reaching the end of its life.

Trees growing near to an active volcano face an uncertain future for several years after an eruption, a study has suggested.A reduced ability to absorb essential nutrients from the soil and lower rates of turning sunshine into sugar hampered the trees' growth.A team of researchers also found that toxins released by eruptions continued to limit the trees' growth.The findings appear in the journal Dendrochronologia.The team said that the widespread impact of volcanic eruptions on trees had been well documented, such as the "year without a summer" in 1816, following the massive Tambora eruption in Indonesia in the previous year, which was deemed to be the biggest volcanic eruption in human history.However, they added, there was litt...
