Neste documentário, você vai descobrir como o Sol evolui ao longo de bilhões de anos, quando ele entrará na fase de gigante vermelha, o que acontecerá com a Terra, se a humanidade teria alguma chance de sobreviver e quais são as descobertas mais recentes da astronomia sobre o destino do Sistema Solar.

Prepare-se para conhecer fatos surpreendentes sobre a evolução estelar, o futuro da Terra, a expansão do Sol e os eventos que podem transformar completamente o nosso planeta. A resposta pode ser muito diferente do que a maioria das pessoas imagina.

I've been diving deeper into Apollo history, and the Lunar Rover turned out to be far more interesting than I expected.

I put together a short documentary explaining why it looked unusual and how it worked on the Moon. I'd really appreciate any feedback. As always, thank you for being so supportive.

For decades, it was believed the Moon was completely dry. I made this video to showcase how each technological step gradually revealed the presence of water on the Moon and transformed our understanding of lunar science. I hope you enjoy it, and thank you for your support.

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.
