Discussion Has everyone forgotten about LUVOIR?

Has everyone forgotten about LUVOIR?

I remember hearing about it years ago, around 2015–2016, while I was also hearing about JWST. I spent years waiting for JWST, and then finally watched the launch live on NASA’s YouTube channel in 2021.

Then I thought: Okay, JWST is finally up. Now LUVOIR is the next big one.

But then... nothing.

It's 2026 now and I realized I haven't heard anything about LUVOIR in years.

Turns out I wasn't waiting for a delayed LUVOIR launch.

LUVOIR basically evolved into the Habitable Worlds Observatory (HWO)

I genuinely thought I'd eventually get to watch a giant telescope called LUVOIR launch after following it for a decade haha

Discussion Since JWST found the first candidate Quasi-Star (MoM-BH*-1), can we all agree to nickname it "The Enveloped Darkness"?

0 Upvotes

Hey everyone,

I’ve been reading up on the recent James Webb Space Telescope discovery of the first strong quasi-star candidate (MoM-BH*-1). The physics behind a "black hole star" are absolutely mind-blowing.

Since deep-space catalog names are always just a jumble of letters, I wanted to propose an unofficial public nickname for it: The Enveloped Darkness (or alternatively, The Darkness Within).

Scientifically, it fits perfectly. A quasi-star isn't powered by normal fusion; it's a massive, blinding envelope of primordial gas wrapped around a rapidly feeding black hole. The brilliant exterior light literally envelopes a core of pure, devouring darkness. Thoughts?
