Advanced Civilizations Could be Communicating with Neutrino Beams. Transmitted by Clouds of Satellites Around Neutron Stars or Black Holes

In 1960, famed theoretical physicist Freeman Dyson made a radical proposal. In a paper titled “Search for Artificial Stellar Sources of Infrared Radiation” he suggested that advanced extra-terrestrial intelligences (ETIs) could be found by looking for signs of artificial structures so large, they encompassed entire star systems (aka. megastructures). Since then, many scientists have come up with their own ideas for possible megastructures.

Like Dyson’s proposed Sphere, these ideas were suggested as a way of giving scientists engaged in the Search for Extra-Terrestrial Intelligence (SETI) something to look for. Adding to this fascinating field, Dr. Albert Jackson of the Houston-based technology company Triton Systems recently released a study where he proposed how an advanced ETI could use rely on a neutron star or black hole to focus neutrino beams to create a beacon.

Small, Tough Planets can Survive the Death of Their Star

Sad fact of the Universe is that all stars will die, eventually. And when they do, what happens to their babies? Usually, the prognosis for the planets around a dying star is not good, but a new study says some might in fact survive.

A group of astronomers have taken a closer look at what happens when stars, like our Sun for instance, become white dwarfs late in their lives. As it turns out, denser planets like Earth might survive the event. But, only if they’re the right distance away.

Is Dark Matter Made of Axions? Black Holes May Reveal the Answer

What is dark matter made of? It’s one of the most perplexing questions of modern astronomy. We know that dark matter is out there, since we can see its obvious gravitational influence on everything from galaxies to the evolution of the entire universe, but we don’t know what it is. Our best guess is that it’s some sort of weird new particle that doesn’t like to talk to normal matter very often (otherwise we would have seen it by now). One possibility is that it’s an exotic hypothetical kind of particle known as an axion, and a team of astronomers are using none other than black holes to try to get a glimpse into this strange new cosmic critter.

Today is the Highest Concentration of Atmospheric CO2 in Human History. 415 Parts Per Million. Last Time it Was This High, There Were Trees at the South Pole

Think about this for a minute: We humans and our emissions are helping turn back the climatological clock by 2 or 3 million years, possibly more. Not since that time, called the Pliocene Epoch, has the CO2 ppm risen above 400.

Way back then, the CO2 helped keep the Earth’s temperature 2 to 3 degrees C warmer than it is now. And the Earth was a much different place back then.

NASA’s 2024 Moon Mission is called Artemis, and Will Need an Additional $1.6 Billion in Funding

The Moon’s going to have more human visitors in the year 2024. NASA has announced that their mission to the Moon, which is named Artemis after the Greek goddess of hunting, has been advanced by four years, from 2028 to 2024. But there’s a catch: they need more dough to do it. $1.6 billion more.

NASA Senior Engineer Kobie Boykins talks About Exploring Mars. And I was There to See it!

As part of National Geographic Live, Chief Engineer Kobie Boykins of NASA’s Jet Propulsion Laboratory (JPL) has been touring the world of late. As part of the program’s goal of having featured speakers share their behind-the-scenes stories, Boykins has been showcasing the accomplishments of NASA’s Mars robotic exploration programs – of which he played a major role.

This week, his tour brought him to my hometown, where he delivered a presentation to a packed house at the Royal Theatre here in of Victoria, BC. Titled “Exploring Mars”, Boykins shared personal stories of what it was like to be an integral part of the team that created the Sojourner, Spirit, Opportunity, Curiosity and Mars 2020 rovers. I had the honor of attending the event, and being able to do a little Q&A with him after the show.

The Blue Origins Founder Wants to Get to the Moon by 2024

Blue Origin is going to the Moon. In an hour-long presentation in Washington DC on May 9th, Jeff Bezos spelled out his plans for reaching the Moon, confirming what many guessed he was hinting at in a tweet from the previous week.

Bezos and his company, Blue Origin, are developing a lunar lander capable of landing a large payload of 6.5 metric tons (14,330 lbs.) on the lunar surface. The lander is being called ‘Blue Moon’ and the target date for its rendezvous with the Moon is 2024.
