Hubble Telescope Detects Wake of Betelgeuse’s Hidden Companion Star, Confirming Long-Held Theory
Hubble Telescope observations have revealed a dense gas wake in Betelgeuse’s atmosphere, confirming the presence of a hidden companion star named Siwarha. The discovery explains the red supergiant’s unusual brightness changes and offers new insight into how massive stars evolve and shed material before becoming supernovae.

Betelgeuse and the Crab Nebula Reveal Stellar Death and Rebirth in Multi-Telescope Views
Betelgeuse’s unusual dimming and the Crab Nebula’s remnants offer insight into stellar death and rebirth. Composite images from multiple telescopes show gas filaments and a neutron star, illustrating how massive stars explode, enrich space with heavy elements, and seed future star formation. These observations help scientists trace stellar life...

NASA Telescopes Capture First-Ever Companion Star Orbiting Massive Red Supergiant Betelgeuse
Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations. Dubbed “Betelbuddy,” the discovery reveals an extreme binary system that challenges existing models of stellar evolution and may offer clues to Betelgeuse’s future.

Astronomers Solve Betelgeuse’s 6-Year Dimming Mystery by Spotting Secret Companion Star
Astronomers have finally spotted Betelgeuse’s hidden companion star, ending a 1,000-year mystery about its six-year dimming cycle. Using Gemini North’s advanced imaging, researchers captured the first image of the elusive companion orbiting deep within Betelgeuse’s atmosphere. The discovery solves a stellar puzzle and offers new insight into ...

Supernovas May Have Triggered Deadly Ancient Climate Shifts, and They Could Happen Again
New research links nearby supernovas to drastic shifts in Earth’s ancient climate. These cosmic explosions may have eroded the ozone layer, triggered global cooling, and even caused mass extinctions. Tree ring data supports the theory, raising concerns that future stellar events, like the expected Betelgeuse explosion, could again pose serious at...

Supergiant Star Betelgeuse Might Have a Hidden Companion Star, New Study Claims
Recent research suggests that Betelgeuse, the prominent red supergiant in the Orion constellation, might have a hidden companion star, nicknamed “Betelbuddy.” Led by Jared Goldberg at the Flatiron Institute, the study proposes that this unseen star could be influencing Betelgeuse's unusual brightness fluctuations. Using computer simulations, th...

One Of The Brightest Stars To Disappear In "Once In A Lifetime" Event
The star has become prominent for its "fluctuating brightness". Several scientists have also raised concerns that it could explode soon.

Hubble Observes Supergiant Red Star Healing After Massive Explosion
Betelgeuse, an aging star that lost a chunk of its visible surface in 2019, is healing with time, astronomers say. The star will eventually explode into a supernova. The recent observations give a glimpse into how red stars lose mass in the later years of their lifespan.

Dimming of Betelgeuse: Here’s Why the Glow of One of Brightest Stars Faded
Betelgeuse, a red supergiant, abruptly started going dark in December 2019

A Dying Star One Thousand Times Bigger Than The Sun Could Soon Explode
Betelgeuse, a reddish star that is part of the Orion constellation, may be entering a pre-supernova phase - where it gets fainter before collapsing in a fiery explosion.

Is Betelgeuse, One of the Sky's Brightest Stars, on the Brink of a Supernova?
Since the start of December, the star Betelgeuse - the gleaming right shoulder of the constellation Orion - has been rapidly growing dim.
