Hi, I'm Michael Keaton. You may remember me from such documentaries as Birdman and Birdman 2: This Time Without Underwear.

Paywall crap

Here's a different article - https://phys.org/news/2026-07-astronomers-strongest-evidence-betelgeuse-companion.html

>At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team led by French researcher Miguel Montargès obtained the clearest image yet of what is likely Betelgeuse B, the star orbiting Betelgeuse. "This is the conclusion of a century-long quest," Montargès says.

Thank you.

generally you can use archive.ph and similar websites to get around paywalls these days, for anyone who wasn't aware.

I love the acronym VLT.....so.......unoriginal.

ecafsub | 3 hours ago

That’s not an acronym. It’s an initialism, like CPU.

What you don't pronounce it See-Poo? /s

I call it See poo.

For those wondering the difference, NASA is an acronym, since you say it as a word, not letter by letter.

Just wait til you hear about the Extremely Large Telescope and the (unfortunately cancelled) Overwhelmingly Large Telescope!

So does this mean it’s not going supernova sometime soon?

That type of star has a short lifespan and will definitely go supernova relatively soon but on a cosmic timescale, not a human one.

Hope it doesn't have a single planet with weird aliens on it

I swear this was something I already knew from somewhere?

Maybe I'm thinking of something else

WmNeo | 2 hours ago

I think this hypothesis was put forward after the strange dimming and glowing seen last couple of years. This might be confirming a hypothesis we heard about at least 2 years ago.

So does this mean it's more likely to explode or less likely to explode in my lifetime?

PrecedentialAssassin | 2 hours ago

If you're going to live to be 100,000 you have a decent chance of seeing it

Ray1987 | an hour ago

So there's still hope!

Some of the flickering from Betelgeuse that was mistaken for a «any day now» sign was probably the star. So in short term it lessens it.

Betelgoosed.

How the hell after all this time we just found this out? I know it's bright but wouldn't a radio signal produce two waveforms?

Betelgeuse, Betelgeuse!!

Thank goodness it isn't 3 stars or we would be in trouble

Pretty embarrassing that this took so long.

You should be embarrassed! Astronomers could have found this way earlier if only you'd built a better telescope for them, you lazy bum.

I thought that this was already known? Was it just speculated but not confirmed and this is the confirmation?

>***"Honestly, I thought we did not have the sensitivity to detect Betelgeuse B*** as it was predicted," Montargès explains. "Because it is more massive than predicted, we see it!" Originally thought to be about as massive as the sun, the new observations reveal that Betelgeuse B has around two to three times the mass of the sun.

>"The fact that we can still discover a nearby companion, more massive and brighter than the sun, around such a well-studied star is remarkable," Montargès says. "These are among the best moments in science: seeing something new, unexpected."
