…image shows the infrared light being emitted by the dust surrounding Betelgeuse in December 2019. The SPHERE image shows Betelgeuse’s visible surface, which has a size close to the orbit…
…Mystery of Betelgeuse’s Dip in Brightness Solved When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community…
…although not as dramatically as earlier in the year. Dupree hopes to use STEREO for more follow-up observations to monitor Betelgeuse’s brightness. Her plan is to observe Betelgeuse again next…
…not a sign of imminent explosion: study shows Betelgeuse likely isn’t cold, just dusty. Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around…
…Illustration credit: NASA, ESA, and E. Wheatley (STScI) Recalibrated Betelgeuse’s mass, radius, and distance. Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the…
An image from the Heliospheric Imager aboard NASA’s STEREO spacecraft shows the star Betelgeuse, circled. For several weeks in 2020, STEREO was the only observatory making measurements of Betelgeuse because…
…of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse’s surface….
…was partially concealed by a cloud of dust, solving the mystery of the ‘Great Dimming’ of Betelgeuse. When Betelgeuse, a bright orange star in the constellation of Orion, lost more…
An MIT-led search for axions from nearby star Betelgeuse (pictured here) came up empty, significantly narrowing the search for hypothetical dark matter particle. Credit: Collage by MIT News. Betelgeuse image…
This graphic illustrates how the southern region of the rapidly evolving, bright, red supergiant star Betelgeuse may have suddenly become fainter for several months during late 2019 and early 2020….

Betelgeuse illustration. Credit: NASA, ESA, and E. Wheatley (STScI) It may be another 100,000 years until the giant red star Betelgeuse dies in a fiery explosion, according to a new…
…Barbara have already made predictions about the brightness of the supernova that would result when a pulsating star like Betelgeuse explodes. Unlike most stars, Betelgeuse is large enough and close…
The new e-MERLIN radio image of Betelgeuse. The image is 1 arcsecond on a side, north is up and east is to the left. The observed frequency is 5.5-6.0 GHz…
…star and this first attempt has resulted in the highest-resolution image of Betelgeuse available. Betelgeuse is one of the largest stars currently known — with a radius around 1400 times…
The red supergiant star Betelgeuse is seen here in a new view from the Herschel Space Observatory, a European Space Agency mission with important NASA participation. Credit: ESA/Herschel/PACS/L. Decin et…
What are some skywatching highlights in September 2022? Mars is on the move this month, forming a “red triangle” with bright red stars Aldebaran and Betelgeuse. Saturn and Jupiter fly…
…violent than Betelgeuse—experiences much longer, dimmer periods that last for years. New findings from NASA’s Hubble Space Telescope suggest the same processes that occurred on Betelgeuse are happening in this…
