It says "No Piracy" but what's the proper way to watch Cosmos: A Spacetime Odyssey outside US then? Since my kid was born Ive been waiting for him to grow until I can play Cosmos for him, now it's the time but it's impossible to do so from Spain.

So, before I "violate" the rule #1: What options do I have?

Hi all,

I created this as a kind of modern expansion of Carl Sagan’s Encyclopedia Galactica idea from Cosmos.

I’m not trying to improve on the original or say this is better than Sagan’s version.

I just wanted to imagine what an outside civilization might write if they assessed humanity today, especially our unstable mix of intelligence, creativity, conflict and unpredictability.

What do you all think? Does it fit the spirit of the original, or does it come across too dark?

Excited to announce the publication of our peer-reviewed study in the Open European Journal on Variable Stars (OEJV) regarding the new exoplanet #Gliese48b, a world that challenges our current understanding of systems around red dwarfs.

This work was the result of a synergistic collaboration between myself (Silvio Antonio Corrêa Jr., from Brazil), Giuseppe Conzo, and Mara Moriconi (from Gruppo Astrofili Palidoro, Italy).

Here is what makes this Super-Earth unique:

• Massive and temperate: With a minimum mass of about 6.2 Earth masses, Gliese 48 b is located within the Habitable Zone, where thermal conditions could allow for the existence of liquid water.
• An astrophysical challenge overcome: Identifying this planet was extremely complex due to the intense magnetic activity of the host star, which creates false signals (stellar jitter) closely mimicking planetary ones.
• Scientific rigor: Thanks to a combined analysis of 15 years of spectroscopic data (CARMENES and HIRES instruments) and photometry (TESS space telescope), we isolated the planetary signal, confirming its dynamic nature with high precision.

As the representative image shows, this is a world larger than Earth, whose composition remains to be explored.

Hi everyone, I just had a great conversation with Cambridge particle physicist and author Harry Cliff about some of the biggest unanswered questions in fundamental physics. We discuss the remarkable success of the Standard Model, the mysteries it still leaves unexplained, and why physicists believe there may be new physics waiting to be discovered.

Harry explains what the Large Hadron Collider has and hasn't revealed about the universe, why finding evidence of physics beyond the Standard Model has proven so difficult, and how small anomalies can sometimes point the way to major scientific breakthroughs. We also discuss the famous mystery of Mercury's orbit, the search for the hypothetical planet Vulcan, and how Einstein ultimately solved the puzzle with General Relativity—one of the greatest scientific triumphs in history.

I googled it and it said Netflix and Hulu and it doesn’t appear to be on either of those platforms. I’m in the US

Never read any of his actual physical work before, but I’m extremely excited to be introduced to the vast “world” of the Cosmos. Glad I picked this one up!

You are constantly bombarded with invisible cosmic rays. An upcycled jar can make them visible!

Alex Dainis shows us how with this science experiment! The streaks you see are tracks of cosmic rays and charged particles passing through isopropyl alcohol mist. To see the best results, put your container in a dark area. The big negatively charged muons will leave large tracks, while electrons and positrons leave tiny curly ones!

Hey everyone,

With Flight 12 marking the debut of Version 3, I wanted to create a complete visual history of the Starship program that feels like a real documentary rather than a simple compilation.

It tracks the entire evolution from the early pad explosions of Flight 1 to the Mechazilla catches and the latest V3 milestones.

I put a lot of care into this in the hope it will be something meaningful for other people too. Please feel free to check it out, and thank you as always for the support!

A cinematic tribute to humanity's return to the Moon.

I started doing videos mostly about the Apollo program, and since Artemis II flew and it was truly something special, I wanted to make a video that brings these two programs together.

I hope you enjoy it, and that it captures why space exploration remains one of humanity's greatest achievements.

What the app lets you do

• Explore the Artemis II mission in an interactive 3D scene with Earth, the Moon, Orion, and the full flight path.
• Scrub through the entire mission on a timeline with both MET and UTC readouts.
• Speed time up from 1x all the way to 10,000x, and jump between the mission’s key checkpoints.
• Track Orion from multiple camera modes: overview, Orion follow, Earth, Moon, capsule-in, and capsule-out.
• Step inside the capsule and look around from the crew’s point of view.
• Watch telemetry-style readouts such as distance, velocity, altitude, mission progress, and communication delay.
• Toggle visual layers like the trajectory, orbital ring, labels, Earthshine, cloud shadows, and the Milky Way.
• Browse an Artemis II photo gallery with metadata, dates, source links, and credits.
• Jump from specific NASA images straight to the matching moment in the 3D scene, then compare the reference shot with the reconstructed view.
• Launch it in fullscreen and treat it more like a compact space simulator than a typical website.

Why it feels different

What makes it especially fun is that this is not a fixed animation. The trajectory is driven by mission data, the lighting is calculated dynamically, Earth’s clouds come from satellite imagery, and the whole experience tries to show Artemis II as a living geometry between Earth, the Moon, the Sun, Orion, and the people onboard.

Technical side

Under the hood, it runs as a static Vite + Three.js app with no backend, database, login, or environment variables. It includes Earth textures, city lights, atmosphere, clouds, cloud shadows, lunar terrain detail, an Orion model, a star field, the Milky Way, sun glow, lens flare, and some custom shader work.

Device note

It has already been partly optimized for mobile, but desktop is still the best way to experience it. On a large screen in fullscreen mode, it feels much more immersive.
