I used Space Engine to make this video about habitable exoplanets

As of September 2019, these are the 5 potentially habitable exoplanets closer to Earth:


  

 
To which of these exoplanets would you go to? why?

The Habitable Exoplanet Hunting Project

Hi all! We are looking for more observatories and amateur astronomers who might want to join the project. The Habitable Exoplanet Hunting Project is a worldwide network of amateur astronomers searching for new potentially habitable exoplanets. I am coordinating over 20 observatories located in 5 co...

BREAKING: New potentially habitable exoplanet found around Teegarden's star

Astronomers have discovered a potentially habitable exoplanet around Teegarden's Star. Teegarden is an old red dwarf star 12 light-years away in the Aries constellation.   The exoplanet found, called Teegarden b, has a minimum mass almost identical to Earth.   It orbits within the star's ha...

3 facts maybe you don't know about antimatter

Hi!  I would like to share with you guys some facts you might not know about antimatter: 1º - Recent studies suggest that an antimatter spacecraft could achieve up to 70% the speed of light, reaching Proxima b in just about 6 years. 2º - The maximum time that antimatter has been stored is 405 days....

Do you think we are alone in the Milky Way?

So.. recent estimations for the Drake Equation (Maccone, 2012) suggest that there could be around 4,600 civilizations in our galaxy that are able to release detectable signals. I find this number a little bit excessive, so I plugged some of the values of our Solar System into the equation a...

Do you think Tau Ceti e is inhabited?

Hi! Guys do you think Tau Ceti e is inhabited? It was recently confirmed ( https://twitter.com/i/web/status/1084742558041993216 ) and it is considered a potentially habitable exoplanet (http://phl.upr.edu/projects/habitable-exoplanets-catalog) I just made a video about it, just in c...

These Are The Most Promising SETI Radio Signals

Hi!  Just in case someone is interested in SETI, I made a video about the most promising radio signals detected so far.  Here it is:  4MxNEfIfQjI I Hope you enjoy it!  What is the most promising SETI radio signal for you guys? Do you think we will discover an intelligent civilization with the SKA ar...

Detect exoplanets by yourself with the cheapest equipment

Hi guys, I detected my first exoplanet (hd 189733 b) and made a video about it showing step by step how I did it. I thought it could be useful for the people interested in the topic or already starting with transit photometry.   The star has an apparent magnitude of 7.7 and the exoplanet pr...

What exoplanet might reply us back?

So.. we have sent radio messages to Gliese 273 b and the Gliese 581 system, where planet 'g' hasn't been confirmed yet but it is potentially habitable.  Which of these exoplanets, if any, do you think might reply us back?  Put in other words, which of these exoplanets do you think it might have inte...

TESS: the space telescope that will find nearby Earth-like planets

As I did not see any post on TESS in the whole forum, I created this one to talk about it. The launch will be on Monday at 6:32 PM EST time. I read in the website that 'science operation will begin at the start of June, with the first data reaching the archive at the beginning of December'....

What do you think about the EM drive?

Last year China claimed that they had built an EM drive.   The Chinese Space Agency released a video (this one:  https://www.youtube....eature=youtu.be ), but they don't go into detail.   What do you think about it? Do you think they are just achieving insignificant amounts of thrust?  ...

What do you think about the super flare of the star Proxima Centauri?

good points, indeed active flare stars are a problem, but i think that if proxima b had a magnetic field stronger than earth, those flares wouldn't be much of a problem

What do you think about the super flare of the star Proxima Centauri?

Hi guys, I hope you are doing well So.. the other day I read that Proxima Centauri released a huge flare last year, decreasing the chances of existing life in Proxima b   What do you think about it? I also read that the flare lasted 2 minutes.. what if the flare happened in the part of the star tha...
