Proxima Centauri, Closest Star to Earth, Has Exoplanet Where Temperature and Water Might Make It Habitable

“One of the main features that distinguishes this planet from Earth is that
the light from its star is mostly in the near infra-red. These frequencies of light interact much more strongly with water vapour and carbon dioxide in the atmosphere, which affects the climate that emerges in our model [of Proxima Centauri and exoplanet.]”

- James Manners, Ph.D., Astronomy & Astrophysics Journal, May 16, 2017

Part 1 – Aliens: Scientists Search for Extraterrestrial Life

“I would say the odds are even 50/50 that in a year or two, we will
have discovered life elsewhere — and that's pretty big stuff!”

What Is Creating Phosphine — A Biosignature on Earth — in the Atmosphere of Venus?

“I thought we'd just be able to rule out extreme scenarios, like the Venus clouds being stuffed full of organisms. When we got the first hints of phosphine in Venus' spectrum, it was a shock!”

Human Births On Mars? New Research Indicates Human Sperm Could Last 200 Years On Red Planet.

“NASA and several organizations are now beginning to plan manned missions to Mars.  ... However, interplanetary deep space is populated not only by microgravity, but also by strong radiation such as galactic cosmic rays, which originate outside the solar system, plus solar particles, which include high-charge, high-energy particles that are difficult to shield from a spacecraft.”

Beyond Egypt to Peruvian Plains of Nazca, Cats Mummified for Eternal Life.

“The ancient Egyptians were not obsessed with death. They were obsessed with life!  So mummification was anticipating life after death with the goal to perpetuate living forever.”

“Either this Venus phosphine discovery is a mistaken identity, that we don't know what the chemical is? Or some strange chemistry that we are not aware of? Or biology.”

A Mysterious White Spot in Martian Sky and Surprising Methane Spike On the Red Planet.

“Cosmic ray particles accelerated to near the speed of light can shoot into our solar system and can hit the Curiosity rover camera images leaving a bright spot.”

— Doug Ellison, NASA Technician with Curiosity rover camera

“The first step to understanding the ultimate question — what is the origin of the Martian methane? — is to understand where it is released.”

— Planetary scientist Marco Giuranna, Ph.D., Italian National Institute for Astrophysics
