 * Astronomers estimate that there are as many as "One Septillion" (1024 or, 1 with 24 zeros) stars in the observable Universe – more stars (and earth-like planets) than all the grains of beach sand on planet Earth  – many more stars, at an estimated 10100, may be contained in a Universe (observed and unobserved) considered Inflationary.


 * Astronomers confirm (as of ) => exoplanets (in  exoplanet systems and  multi-exoplanetary systems) – after studying only a very, very small portion of the starry sky.

Perseverance rover & Ingenuity helicopter => sols (1226 days days)  (landed February 18, 2021). Curiosity rover => sols ( days)  (landed August 6, 2012). ( USA flag on Mars – Mars Weather: Perseverance*Curiosity*InSight – Mars rocks – Martians found? ).
 * The NASA probes currently active on the planet Mars (as of July 29, 2024) are the following:


 * A spaceship from planet Earth speeding 165,000 miles an hour (as fast as our fastest one), would take nearly 20,000 years to travel beyond our Solar System to the nearest star Proxima Centauri – with no worthy place to land.


 * Spaceship planet Earth is speeding about "One Million" miles an hour through outer space and, along with the rest of the Milky Way Galaxy, is traveling toward Andromeda Galaxy. (WikiTalk)


 * The Universe contains life – on planet Earth – at least – and – we are not alone – life abounds – wherever we are – with microorganisms – at the very minimum.


 * Biologists currently understand that microorganisms were the only known life forms present during the earliest 85% of time since the planet Earth was formed 4.54 billion years ago – Plants and Animals appear much more recently – in the latest 15% of time – Modern Humans, much more recently yet – in less than the latest 0.005% of time.


 * Biologists have estimated that over 99% of all species of life forms that have ever lived on planet Earth are now extinct. Further, the total number of living cells on the Earth currently is estimated to be 1030; the total number since the beginning of Earth as 1040, and the total number for the entire time of a habitable planet Earth as 1041.


 * Chemists have determined that all life forms on planet Earth are based on one particular chemical – with astronomical variations.


 * Physicists have estimated that there is about 1082 (1 with 82 zeros) atoms in the observable Universe, and that additionally, at least 99.9999999% of all the matter in the Universe, from the very small to the very large, is empty space.
