- Hubble Sees Red Supergiant Star Betelgeuse Slowly Recovering After . . .
Analyzing data from NASA's Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME)
- Betelgeuse - Wikipedia
By August 2020, long-term and extensive studies of Betelgeuse, primarily using ultraviolet observations by the Hubble Space Telescope, had suggested that the unexpected dimming was probably caused by an immense amount of superhot material ejected into space
- Huge explosion detaches part of the star Betelgeuse and “darkens” it
A team of experts says the star Betelgeuse is recovering from a massive, “never-before-seen” surface mass ejection that obscured it When the bright red supergiant star Betelgeuse exploded in 2019, the Hubble Space Telescope and other observatories were there to see it

But Betelgeuse’s overwhelming size and brightness meant it wasn’t clear whether the smaller star would ever be observable NASA’s Hubble Space Telescope and the Chandra X-ray Observatory both drew a blank

This is the first direct image of a star other than the Sun, made with the Hubble Space Telescope Called Alpha Orionis, or Betelgeuse, it is a red supergiant star marking the shoulder of the winter constellation Orion the Hunter

Betelgeuse Betelgeuse imaged in ultraviolet light by the Hubble Space Telescope Betelgeuse is a red supergiant star roughly 764 times as large as the Sun For comparison, the diameter of Mars ’s orbit around the Sun is 328 times the Sun’s diameter

In the first two panels, as seen in ultraviolet light by NASA’s Hubble Space Telescope, a bright, hot blob of plasma is ejected from a convection cell on the star’s surface In panel three, the expelled gas rapidly expands outward, cooling to form an enormous cloud of obscuring dust grains
