NASA Confirms Boost Mission for the Swift Satellite was Unsuccessful, Will Likely Reenter Atmosphere Later This Year

For those unaware, Swift was actually the most successful and most cited NASA telescope ever if you look at the number of citations. Despite this it has no replacement so there was hope that a mission could boost it into higher orbit, but it appears this was unsuccessful :(

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

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?

Andromeda Galaxy with Northern Lights

This was my first time trying to capture the Andromeda Galaxy, and I succeeded with the aurora borealis popping in! That faint light in the middle? That’s a galaxy 2.5 million light years away.

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
