James Webb Space Telescope Reveals That Most Galaxies Rotate Clockwise

This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or astronomers have been measuring the universe's expansion incorrectly

I heard in the Southern Hemisphere they rotate anti-clockwise

Every picture from Venus' surface, ever

In 1975 and 1982, four of the Soviet Union’s Venera probes captured our only images of Venus’ surface.

I remember reading the history of those Venera probes on Wiki a few years back, there were a maddening number of them that reached the surface of Venus only for the lens cap of the cameras to jam / fail to open. The '70s landers were an amazing achievement for the time but you'd think that we could surely do a bit better with 50 years of tech advancement. It doesn't seem to be a priority for any of the space agencies to go back there for whatever reason though.

BAN #447: Wait. HOW MANY supernova explode every year?

25 July 2022 Issue #447

Surely supernova is by definition an explosion so they don't explode because it's the star that explodes?

The Great Filter is a proposed explanation for the Fermi Paradox. It suggests there's a barrier (or series of barriers) that prevents life from advancing to a stage where it can become spacefaring and visible to others.

In simple terms:​

The Great Filter is something that wipes out or prevents intelligent civilizations from spreading across the galaxy.

It could exist at​

1. Before life begins: Maybe life itself is incredibly rare, and Earth is a miracle.
2. Before intelligence arises: Single-celled organisms may be common, but evolving into intelligent beings is extremely unlikely.
3. Before advanced civilization: Intelligent life may rarely survive long enough to develop space travel.
4. In the future: Advanced civilizations may inevitably destroy themselves (e.g. nuclear war, AI, climate collapse) before they can expand.

Why it’s unsettling:​

• If the Great Filter is behind us, then we may be extremely rare and special.
• If the Great Filter is ahead of us, then we might be doomed like countless others before.

Would you rather hope the Great Filter is in our past—or think it's still coming?

from the source material, it was the AI that added in the bit about AI.

Space is very very big and time is very very long. The chances of our existence overlapping within range of another crowd that also active at the same time are vanishingly small.

What if the other crowd had an immortal metabolism like tardigrades

Whether he is or isn't , that kind of hyperbolically-negative writing is just awful. It's the kind of thing you'd expect from the permanently-angry-and-happy-about-it end of the american political spectrum. Also it doesn't even cover this week's explosion(s).

After its third failed mission - what next for SpaceX?

Despite this being Starship's greatest progress to date, the spacecraft sprang leaks, spun out of control and broke up in orbit.

Made from over 1100 images captured by NSF-DOE Vera C. Rubin Observatory, the video begins with a close-up of two galaxies then zooms out to reveal about 10 million galaxies. Those 10 million galaxies are roughly .05% of the approximately 20 billion galaxies Rubin Observatory will capture during its 10-year Legacy Survey of Space and Time. Credit: NSF–DOE Vera C.
