Venus resembles our Earth in so many ways, yet in many others it's frightningly different. Was Venus always this way? Could it have once been habitable? And if so, what went wrong? Why did Venus transform to the hellscape we see today? Let's explore the world next door...

Those yellow photos of Venus have stayed in my head ever since, so mysterious and haunting to think that we actually landed a craft there. Wow! Just a little update, when I said 'we' I meant the human race. I don't care which country landed it there, it's still a miracle and gives me goosebumps to see it.

I admit it, it was me. I'm sorry.

This paints a nightmarish picture of a world whose plate tectonics ground to a halt prematurely. Maybe life continued as normal for a while, but then half a billion or so years later the magma pressure built up to such an intensity under the entire fused surface that it burst through the lid in a single catastrophic release. It's like that firework display where everything went off at once instead of in sequence. All the volcanic activity that would have happened slowly on Earth over billions of years all happened at the same time, leaving a charred, dead, blown-out world with nary a shred of evidence that it had ever been otherwise.

I never even thought about this butā¦ imagine a solar system like ours but with life on TWO planets simultaneously evolving separately from eachother. Imagine looking at mars satalites for the first time and see animals and trees. Wow

Itās interesting to hear the depiction of Venus being a tormented planet instead of an evil twin to earth, a place that simply couldnāt control its own fate rather than actively trying to be hostile

127 minutes for Venera 13? That's a lot higher than I would have guessed. I'm surprised and impressed.

When you said "we're incredibly lucky to have a planet like Venus so close by," and gestured off-screen, I half expected you to be like "And here she is, right here in the studio!" Anyway, love your videos, love your energy. Keep it up dude š

I had the pleasure of visiting Parkes observatory in New South Wales, Australia. There was an astronomy enthusiast event at the time of our visit. It was a sunny, clear day and one of the enthusiasts pointed out Venus, shining bright in broad daylight. I ended up observing it through a telescope and was stricken by the sight of this amazing planet.

Venus could have an entire fossil record of life that evolved independently from Earth that couldāve been destroyed during Venusās runaway greenhouse effect.
If thatās the case thatās such a tragedy for science, imagine what couldāve walked the surface of Venus.

Quoting Boromir to explain the severity of Venus.
Itās because of things like this you are amongst my favourite YouTubers. And my absolute favourite person on the platform. Skill, knowledge, in-depth research.
passion, emotion and a true love for what you do. Youāre a diamond amongst the rough ā¤

I've often pondered what it would be like if Venus, Earth and Mars had all developed life and were each still thriving. Unfortunately, if there were lifeforms that developed anything like we did and were equally as intelligent and advanced as we are, we'd surely be at war with at least one of the two planets because that's just what we do. And yes, I'm fully aware of how unrealistic that is but, technically, it's not entirely impossible.
Of course, when I get to thinking about that kind of stuff, I like to wonder what it would be like if Venus, for example, was still in the condition to support life and had also developed dinosaurs (but not humans) somehow and hadn't experienced an extinction level event, therefore leaving these hypothetical "dinosaurs" to continue to exist there to this day. Yeah, yeah, that's pretty unrealistic as well for so many reasons, but again, not entirely impossible.
I honestly find these types of things pretty interesting to think about, personally, and even somewhat fun to imagine literally countless scenarios, realistic or not.
Somewhere out there, though, there may very well be a solar system with multiple planets that each developed life in very different ways and the thought of actually seeing that is exciting, even though I'm fully aware that it's not something that I will actually ever get to experience.

It would be interesting if there were a time in the past when Venus, Earth, and Mars all had water oceans at the same time.

One does not simply walk onto Venus

The more we study planets like Venus and exoplanets the more it becomes evident how unique the Earth truly is. The Earth too has gone through periods of extreme volcanic activity and yet natural processes on Earth has rebalanced itself to create a happy medium where life continues to flourish. Mars and Venus are also constant reminders of the Earth's fragility and the precariousness of our own existence. As always a beautiful and thought provoking video!

Venus is so amazing. I know we've been very centered on Mars, but there's so much we can learn from Venus. Every planet we investigate will give us that much more of an edge at deciphering exoplanets.

I can just feel your passion when you speak about different topics. Itās great to see we still have people out there pushing the boundaries of humanity.

Among the valuable lessons from Venera probes is that #13 is not bad luck, since Venera 13 lasted longest. Just putting that out thereā¦

This sent chills down my spine I'm not even joking
No matter how hard I try to familiarize myself with space, it still terrifies me sometimes...

So who the hell is going to tell me that Incogni, by requesting data-brokers to share your information with them, is not a data-broker themself? Sketchy, the best way to achieve privacy is to never put your personal information on the internet, unless you REALLY need it.

If Venus and Mars tried harder at school we could have had 3 Earthlike planets. Imagine how much of an incentive space exploration would have if Venus or Mars had a rich biosphere with millions of alien plant and animal species to study, maybe even intelligent life? I once had a dream Venus was full of Koffing pokemon.
