Jan 14, 2020 — Orion is excessive within the early night in January. The pink big Betelgeuse that defines Orion’s shoulder began dimming final October. That is not information; it is a variable star. However it’s now fainter than it has been in a century. Observers suppose it might be heading towards turning into a supernova someday within the subsequent 100,000 years or so. Or it could possibly be subsequent week.
Once we say Betelgeuse is a huge, how huge is that? Larger than the entire photo voltaic system out to the orbit of Jupiter.
St. Lawrence College physics professor and astronomer Aileen O’Donoghue talks with Todd Moe about this, and what else to search for within the evening skies of January. She is an everyday visitor on The Eight O’Clock Hour.
