New Study Reveals Betelgeuse’s Brightness Changes Linked to Companion Star
Recent research led by the Flatiron Institute reveals that Betelgeuse’s brightness fluctuations may be caused by a companion star, affectionately named ‘Betelbuddy.’ This groundbreaking study challenges previous notions of the star’s imminent supernova, suggesting instead that its variability is linked to complex interactions in binary systems. Understanding these dynamics is crucial for predicting Betelgeuse’s eventual fate and contributes to our broader knowledge of stellar evolution.
Rediscovery of T Coronae Borealis: Celebrating John Birmingham’s Legacy in Astronomy
In 1866, John Birmingham made a groundbreaking astronomical discovery by identifying the star T Coronae Borealis, also known as the ‘Blaze Star.’ His observation on a clear night sparked a passion for astronomy, despite the challenges he faced as an Irishman in a politically charged environment. Birmingham’s legacy continues to inspire astronomers today, especially as the Blaze Star reappears in our skies this September, reminding us of the rich history of celestial observations.
Discovery of ‘Missing Link’ Black Hole in Binary System G3425
A groundbreaking discovery of a stellar-mass black hole in the binary system G3425, located 5,800 light-years from Earth, has excited astronomers. This ‘missing link’ black hole, with a mass between 3.1 and 4.4 solar masses, challenges existing theories on black hole formation and evolution. The findings, published in Nature Astronomy, highlight the unique interplay between the red giant star and its dark companion, paving the way for further exploration of cosmic phenomena.
Betelgeuse’s Unbelievable Speed Leaves Scientists Perplexed
Betelgeuse, the 10th brightest star in the sky, has left experts in awe with its unbelievable speed. Scientists are perplexed at how a star so big, roughly 2,000 times bigger than our Sun, can spin so quickly. A new study suggests that the data supporting the rotational speed could actually be tracking the star’s convection movement rather than its true speed. Further observations and studies are needed to clarify the true rotational speed of Betelgeuse.
