“Where are they?”: SETI and modern science fiction

Posted by in categories: alien life, physics

Rather, they looked like whirlpools in space-time. In the universe, every part of space flowed, churned, trembled between madness and horror like fiery flames that emitted only frost. The Sun and the planets and all substance and existence seemed to be only hallucinations produced by the turbulence of space-time.

What does a city of one million people on Mars look like?

Posted by in categories: alien life, computing, virtual reality

An urban utopia on Mars might be closer than you think.

For the past year, creative professionals, students, space geeks—even families—have been creating their visions for a metropolis on the fourth planet from the sun. The final winners of the HP Mars Home Planet challenge were announced today by HP and unveiled in a VR experience at SIGGRAPH 2018, an annual computer graphics convention, in Vancouver.

“The amazing entries from the HP Mars Home Planet challenge give us a virtual window into what life on Mars could be like for a million members of humanity,” says judge Dr. Darlene Lim, a geobiologist and principal investigator, NASA Biologic Analog Science. “Technological advancement is being met by a broad array of foundational space science and planetary research—a confluence that will optimistically serve to accelerate our path toward human exploration and settlement of Mars.”

A $1 Billion Telescope That Will Take Pictures 10 Times Sharper Than Hubble’s Is Now Officially Under Way

Posted by in categories: alien life, transportation

In astronomy, cutting-edge technology often begins with a bunch of bulldozers, busted rocks, and dump trucks.

So it goes with the Giant Magellan Telescope (GMT), which will be the world’s largest and most powerful when it sees “first light” in 2024. Astronomers hope to use the huge observatory to study the ancient universe and look for signs of alien life.

Construction crews atop a Chilean mountain range broke ground for the $US1 billion project on Tuesday.

Why Alien Life Would be our Doom — The Great Filter

Posted by in category: alien life

Finding alien life on a distant planet would be amazing news — or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

Risks for Life on Habitable Planets from Superflares of Their Host Stars

Posted by in categories: alien life, economics, evolution, existential risks

We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the solar system, and exoplanets. We propose that the most powerful superflares can serve as plausible drivers of extinction events, and that their periodicity corresponds to certain patterns in the terrestrial fossil diversity record. On the other hand, weaker superflares may play a positive role in enabling the origin of life through the formation of key organic compounds. Superflares could also prove to be quite detrimental to the evolution of complex life on present-day Mars and exoplanets in the habitable zone of M- and K-dwarfs. We conclude that the risk posed by superflares has not been sufficiently appreciated, and that humanity might potentially witness a superflare event in the next $\sim {10}^{3}$ years, leading to devastating economic and technological losses. In light of the many uncertainties and assumptions associated with our analysis, we recommend that these results should be viewed with due caution.

Astronomers develop formula for finding habitable planets

Posted by in category: alien life

One of the biggest challenges for astronomers searching for habitable exoplanets is trying to match up newly discovered worlds with the increasingly long list of criteria that we believe are required for life to take root. A planet may be at a reasonable distance from its host star, but if that star is too young or too old, or just the wrong type, life as we know it would have a hard time there. Now, researchers are reporting the existence of several new planets that appear to meet all the requirements.

The research, which was conducted by scientists from the University of Cambridge and the Medical Research Council Laboratory of Molecular Biology, focuses on planets that are at a safe distance from their host star, but that are also getting enough UV light to trigger the chemical reactions that serve as the foundation for life to exist.

The researchers involved with the study used data from previous experiments that demonstrated the conditions under which the building blocks of life may have formed. Chemicals produced as a result of carbon-rich meteorites slamming into the early Earth are thought to have been a precursor for life, but the scientists still needed to account for the role that the sun played.
