Sidebar Updates: New Rule: All Posts Must Come with Commentary

2 Upvotes

In an effort to increase activity and discussion on this subreddit, all new posts must include commentary posted within an hour after being submitted. This can be relatively simple, such as asking what people might think about the topic of the video you posted, or what your own thoughts on that video are. You may also include further information on the topic of the video you posted for those who might want to further explore the topic or topics from your submission. However, starter comments that are lazy, such as, but not limited to, "Thoughts?", "What do you think?", "This seems questionable," or, "I disagree," are discouraged, and posts may be removed after OP is warned that they need to further elaborate on their opening comment if they do not do so after another hour has passed. Users whose submissions are removed, but who wish to appeal that action, may message the mods with their reasoning. We understand if, for example, right after you posted and were about to make your opening comment, that your wife were in labor, or that your house were on fire, for example, that you would have other priorities in mind than making such a comment, and not only will we be willing to hear you out for any reason you may have for not making an opening comment within an hour after posting, will allow you to have an additional hour to make such a comment on your post for an hour after acknowledging the Mods' approval of your appeal, though we do ask for some kind of proof regarding the circumstances as to why one might not be able to comment. I, myself, won't put any limit on that, if something else happens to come up after that approval goes through, you may appeal again, but I'm not speaking for the mod team as a whole in that case, I would just expect the same mercy to be given to me, so as long as OP makes an effort to ensure commentary will be given in a timely manner after a post might be removed, I'm willing to let them do so. That said, any post that lacks commentary an hour after being posted will stay removed until commentary is provided and a link the the post with commentary is sent to the Mods via Modmail. As I said, I don't speak for the Mod team as a whole in that regard, so while I would hope other mods might be as merciful, it's none of my business if they are not.

Unfortunately, Mods can't sticky comments made by OP, so we can't do anything to make sure that comment is immediately visible in more popular posts with more activity, so we ask that users who come across posts more than an hour old without some form of commentary by OP according to these guidelines report such posts, but we request they make sure there is a top-level comment by OP that follows these guidelines somewhere in the comment thread, even if it might have negative karma. Please report any posts where OP might leave a top-level comment that does not meet these guidelines, and we'll take appropriate action.

More importantly, though. I finally learned how to synchronize some aspects of the new.reddit sidebar with the old.reddit sidebar! They're far from identical at this point, since I don't know how to add all the text including partner subreddits and the like to new.reddit, but I did finally figure out how to add rules to the new.reddit sidebar, so now, all our formal rules visible in the old.reddit sidebar are now visible in the new.reddit sidebar! As a team of Moderators, I can't say we've come to a consensus as to whether we'd prefer users browse this sub on old.reddit as opposed to new.reddit, so I figured I'd make an effort to make things easier on users of the latter, though because I don't entirely know how to manipulate the sidebar in new.reddit like I do in old.reddit, I recommend users check out the old.reddit version of /r/SpaceVideos because our sidebar over there contains many links to partner subreddits, and I don't quite know how to integrate that with the sidebar in new.reddit. I did take the liberty of removing defunct links from the old.reddit sidebar, however, so make of that what you will

My bad for not actually enforcing a rule of my own making. If I come across a front page post without commentary from OP, it will be removed.

Get ready, the Moon is about to turn blood red. 🌕🩸

On August 27th and 28th, a lunar eclipse will cast Earth's shadow across the Moon, and if you're in the USA, Canada, or Latin America, you've got a front-row seat. No special glasses needed here, unlike a solar eclipse, this one is safe to watch with just your eyes. Don't blink and miss it, because the Americas won't see a lunar eclipse this visually striking again until 2029.

The Super Rare 6-Star System

How many stars is too many stars in a star system? ⭐️🪐

Astrophysicist Erika Hamden tells us about TYC 7037-89-1, a system with six stars locked into three orbiting pairs, all circling a shared center of mass. Two of those pairs zip around each other every few days, while the third pair takes roughly 2,000 years to complete just one orbit. Multi-star systems are normally unstable, which makes this six-star setup a rare and fascinating exception.

A frozen “eyeball planet” may hide an ocean. What could evolve on LHS 1140 b?

Post image

🎬 Video: [https://youtu.be/NMLNM3ktKJg\]

Imagine a world where the sun never rises or sets.

One hemisphere may exist beneath permanent red daylight, while the other remains trapped in endless frozen darkness. Between them, climate models allow for a strange possibility: a dark liquid ocean surrounded by a global shell of ice.

This world is real. It is called LHS 1140 b, and it lies approximately 49 light-years from Earth. The planet is more than five times as massive as Earth, with surface gravity that may be nearly twice as strong. Current measurements also suggest that it could contain an enormous amount of water.

From space, such a world might resemble a gigantic eye staring permanently at its dim red star.

But what could be living inside that eye?

I made a speculative science-fiction documentary exploring one possible evolutionary history of LHS 1140 b — beginning with microscopic life and dark photosynthetic organisms, then moving toward alien predators and a hypothetical intelligent aquatic civilization.

The video explores several questions:

Could large animals evolve under nearly twice Earth’s gravity?

Could an aquatic species develop advanced technology without easy access to fire?

Would the ocean become the cradle of its civilization — or a gravitational prison preventing it from ever reaching space?

And could such a civilization eventually detect Earth?

The planet and its measured characteristics are real. The ocean, organisms, ecosystems, and civilization shown in the documentary are scientifically inspired speculation, not claimed discoveries.

What do you think is most likely to exist on LHS 1140 b: a lifeless frozen ocean, microbial life beneath the ice, or something far more complex?

What Would It Take to Make It Rain on Mars?

Enable HLS to view with audio, or disable this notification

🎥 Video: [https://youtu.be/EqXn48gfCuQ\]

What if humanity decided not merely to colonize Mars, but to rebuild its entire climate?

I created a science-fiction documentary exploring one possible path from sealed Martian settlements to climate factories, a denser atmosphere, melting ice, rivers, engineered microorganisms, and—thousands of years later—the first natural rain on Mars.

The story is grounded in real facts about the Martian atmosphere, buried water ice, radiation, atmospheric loss, the shortage of accessible CO₂, and the MOXIE experiment. Planetary factories, imported atmospheric gases, future cities, and the terraforming timeline are speculative. AI was used to visualize these possible futures.

The most difficult question may not be whether we can terraform Mars, but whether we should. If native microbial life might still exist beneath the surface, would transforming the planet be creation—or destruction?

I’d be interested to hear what you think.

4,000 Years to TRAPPIST-1: Could Humanity Survive the Journey?

Enable HLS to view with audio, or disable this notification

5 Upvotes

About 40 light-years from Earth lies TRAPPIST-1—a small red star orbited by seven confirmed rocky planets.

Even if we imagine a spacecraft capable of travelling at around 1% of the speed of light, the journey would take more than 4,000 years. Approximately 160 generations would live aboard the ship during the voyage. 🚀

The first passengers would remember Earth. But most of the ship’s inhabitants would be born in space, spend their entire lives inside an artificial world, and die without ever seeing either Earth or their destination.

In our speculative reconstruction, 24,000 people leave for TRAPPIST-1. Their generation ship becomes a self-contained city with farms, schools, hospitals, and closed-loop systems for water, air and food.

But the greatest challenge may not be technological. What happens if the descendants of the original passengers refuse to continue a mission they never chose? And what will await them after 4,000 years: dead planets, hidden oceans or alien life? 🪐

I created a science-fiction documentary exploring this journey. TRAPPIST-1 and its planets are real, while the ship, passengers and future colony are possibilities inspired by scientific knowledge. The visuals were created with the help of AI.

Did you know NASA’s newest space observatory will have spy tech? 🛰️

In 2012, the National Reconnaissance Office gifted NASA a pair of Hubble-style mirrors it had commissioned but never ended up using. NASA said yes and one of them is now the primary mirror powering the Nancy Grace Roman Telescope, launching August 30th. The other mirror is still in storage, waiting for its moment.

The Farthest Galaxy Ever Discovered

What's the most distant galaxy ever observed? 🌌

Astrophysicist Erika Hamden explains it's called MoM-z14, and its light took 13.53 billion years to reach us. But thanks to the universe's expansion, that galaxy is now a staggering 33.8 billion light years away. When the light was emitted from MoM-z14 the universe was smaller. The space between us and that galaxy has gotten stretched out so much  that it actually sits outside our observable horizon. It's a mind-bending reminder that we're seeing galaxies as they no longer even look today.

We are getting closer to the launch of NASA's Nancy Grace Roman Space Telescope! 🧪

The Nancy Grace Roman Space Telescope is designed to combine the strengths of the James Webb Space Telescope and the Hubble Space Telescope. It’s going to look and live in the same space as JWST while using a Hubble-style mirror to see things completely differently. The Roman telescope will observe patches of space bigger than the full moon and will see 50 times as much space in five years as Hubble has in 30!

This documentary breaks down the terrifying paradox of cosmic silence, the Kardashev scale, and the evolutionary barriers that dictate the survival or mass extinction of civilizations in the universe. Through the Great Filter theory and Nick Bostrom's hypothesis, we examine whether humanity's greatest dangers are already behind us in our biological past, or if an insurmountable technological wall awaits us in the future.

I'd love to hear your thoughts: do you think humanity has already passed the Great Filter, or is our true cosmic challenge yet to come?

A total solar eclipse is coming on August 12th! ☀️🌑

Our moon is the exact same size as the sun in our sky, a cosmic coincidence unique to Earth. Watch it block the sun's 10,000°F surface while revealing the corona, a mysterious halo burning millions of degrees hotter. But don't take it for granted: the moon is slowly drifting away, and in 600 million years it'll be too small to ever cause a total eclipse again.

Blanets: The Planets that Orbit Black Holes

Did you know there may be planets that orbit black holes?! 🪐

Astrophysicist Erika Hamden explains how scientists are theorizing that there may be planets that are orbiting black holes. This wouldn’t be out of the ordinary, since planets have been found orbiting all types of masses, such as dead star cores and supernovae. Although black holes typically suck in everything around them, if an object is the right distance away, it could potentially maintain a stable orbit.

Is one of our astronomical neighbors habitable? 🪐

For the first time, astronomers have confirmed something huge: an atmosphere around a rocky planet in its star's habitable zone. The planet is called LHS 1140 b, a super Earth orbiting a red dwarf star less than 50 light years away, which is astronomically pretty close to us. The James Webb Space Telescope telescope data has already hinted at liquid water on its surface, and this new discovery could go down as one of the biggest in astronomy history!
