Twenty years after the publication of their game-changing book “Rare Earth,” Ward and Brownlee argue that planets like Earth are likely as rare as ever.
Location, location, location. It matters whether you’re looking for a house — or for humans.
Would anyone have concluded that there was intelligent life on Earth 900 years ago?
A new study found a list of stars that could directly see Earth. And at least seven of them have known habitable planets.
Scientists say in a new report that 1715 star systems have been in a position to view Earth over the past 5000 years.
According to the report published Wednesday in the journal Nature, the study could provide clues on where to look for extraterrestrial life that could have a view of Earth.
The authors wrote that while there has been much research on the position of stars, previous studies did not take into account how the view from star systems has changed over time.
Imagine clothing that can warm or cool you, depending on how you’re feeling. Or artificial skin that responds to touch, temperature, and wicks away moisture automatically. Or cyborg hands controlled with DNA motors that can adjust based on signals from the outside world.
Welcome to the era of intelligent matter—an unconventional AI computing idea directly woven into the fabric of synthetic matter. Powered by brain-based computing, these materials can weave the skins of soft robots or form microswarms of drug-delivering nanobots, all while reserving power as they learn and adapt.
Sound like sci-fi? It gets weirder. The crux that’ll guide us towards intelligent matter, said Dr. W.H.P. Pernice at the University of Munster and colleagues, is a distributed “brain” across the material’s “body”— far more alien than the structure of our own minds.

Our planet’s shadow against the Sun could have been seen from thousands of nearby solar systems.
Before we send out missions to red dwarf stars, we need to double check their ability to sustain life.
Red dwarf stars are the most abundant in the universe and at the top of the list when searching for habitable planets. Why we don’t live around one?
The search for life on exoplanets takes a fairly conservative approach. It focuses on life that is similar to that of Earth.
It’s time to think beyond “Earth-like” exoplanets and turn to some truly unusual places to find alien life: the exomoons of rogue planets in the Milky Way.
Just supposing there is a God(s) ; are He/ She /It interplanetary or are we likely to experience a similar ruinous manifistation of the discord seen here on Earth as the varoius factions of ‘the Godly’. come together? If so, it may be time to start smelting down the plough-shares again.

How do stellar outbursts affect the planets that orbit them?
Scientists surveyed thousands of stars to understand the impact they have on their orbiting planets’ habitability.
