You can call them also in general unknown fundamental "vacuum quanta" (although the model predicts that these must be a type spin-2 Bosons). The term vacuum gravitons used in the SGCV model is because the lack of any better definition and that If they did not have this superluminal vibration energy property the SGCV model theorizes, then they would appear to us as an undiscovered type of massive dark particle graviton of the vacuum.

The main fundamental particle of this presumably hidden substrate - the actual and not the false vacuum - is made of.

This superluminal vibration property of the SGCV model predicts, is maybe the exact reason why we cannot detect this "vacuum quanta" and importantly main reason possibly today that we cannot detect any dark sector dark matter. Although our currently best mainstream theories predict these dark matter particles to be massive (WIMPS), maybe, because they vibrate at a "superluminal state" of energy an out of phase of our reality, these would manifest in our spacetime as particles NOT having any equivalent mass therefore undetectable by known experiments. This hypothesis also explains why QED predicts the quantum vacuum having enormous energy although we empirically defect it as being empty and nothing? Maybe because simply "Empty Space" is actually superluminal energy?...

I’m a space nerd and got tired of jumping between a dozen sites to check this stuff, so I built one app that pulls it all together live: https://spacehud.com

It's almost all visual rather than dry data and tables.

It’s just a hobby site... if you think anything else should be added let me know.

Internal NASA documents lay out plans to update the agency's websites, publications, organizational titles and digital infrastructure with a four-phase "super intelligence" implementation schedule extending into December.

Hey everyone!

Weird post, hoping that it's allowed.

I just went through a pretty awful break up that I did not see coming, I have been struggling to sleep recently but the one thing that helps is thinking about the cosmos and how cool and weird it is.

I was wondering if anyone could share some cool facts, scientific theories, or interesting thoughts about the universe/planetary bodies/matter dark matter/galaxies anything. Even just cool thoughts about what other galaxies could be like. Double points if it's something that we only can explain half of, which gives me something to think about and imagine possibilities as I try to sleep.

I'm not an astronomer or cosmologist, but I am a scientist in a different field so I do understand broad science and maths and philosophy up to a point, huge sci-fi fan too.

Anyway hoping this is allowed and people answer.

Thanks fellow inquirers.

Hi everyone!

I recently launched a new citizen science project on Zooniverse to classify overlapping galaxies. These objects are extremely interesting to us because they can be used to directly measure dust attenuation (absorption and scattering of light). These measurements help us better measure distances and much more. We would appreciate your help classifying these objects and building a much larger catalog of them for future studies!

If you want to learn even more, please check out our blog post as well: https://blog.galaxyzoo.org/2026/09/22/announcing-the-overlap-zoo-project/

Thank you for your time,

Trevor Butrum - Overlap Zoo Team Lead

Our 1yo is the biggest fan of space and the planets. He can distinguish and name all the planets! We try to keep his interest going and reinforce it and he learns so much so everything space like books, videos, stickers. We have been wanting to take him to some kind of place about space play place or kids museum but I cannot find anything for his age. Any recommendations?!?!

We’re located in AZ and happy to travel/roadtrip if it will be really cool for him!

"The cradle of life does not necessarily require a sun."

The Hydrogen-rich exomoon atmospheres could hold liquid water for billions of years.

A moon lost in interstellar darkness may still be able to hold on to liquid water, no star required. A modeling study suggests that some exomoons orbiting rogue planets could stay warm for billions of years, even after their host worlds are thrown out of their star systems and into the cold of deep space.

The finding challenges the familiar idea that potentially habitable worlds must receive light from a nearby star. Instead, the study points to a different engine for habitability — heat generated inside a moon by tidal stress, then trapped by a thick hydrogen atmosphere.

Rogue planets drift through space without orbiting a star. Astronomers think many of them were thrown out of their original planetary systems during violent gravitational encounters.

When a giant planet gets ejected, the orbits of its moons can become stretched into more elongated shapes. As the moon moves closer to and farther from its host planet, the planet’s gravity repeatedly squeezes and flexes the moon’s interior.

That process, called tidal heating, can generate a steady supply of internal heat. Jupiter’s moon Io offers a familiar example: tidal forces make it the most volcanically active body in the solar system. Europa and Enceladus also show how internal heat can keep water-rich worlds active far from the sun.

Earlier studies had already suggested that rogue-planet moons might stay warm enough for liquid water if they built up thick carbon dioxide atmospheres.

But those models ran into a serious problem. In the deep cold expected around free-floating planets, carbon dioxide can condense out of the air. Once that happens, the atmosphere can collapse, and much of the moon’s heat escapes into space.

The new study tackles that problem by swapping carbon dioxide for hydrogen. Hydrogen is the lightest element, and in Earth’s thin atmosphere it does very little to trap heat.

Under very high pressure, though, hydrogen behaves differently. When hydrogen molecules crowd together and collide, they briefly form pairs and clusters that can absorb infrared radiation.

Scientists call this process collision-induced absorption. In plain terms, a dense hydrogen atmosphere can act like a surprisingly strong heat blanket.

So with the recent videos popping up of the launch that caused the cool jellyfish effect thing in the sky, I’m wondering how easy it is to predict these sorts of things. For example, there’s a falcon 9 scheduled to liftoff at 6:30am in a few days. Is it reasonable to think that there could be a visual phenomenon with this launch or are there more things to consider than just time of day when trying to predict said phenomenon?
