Everyone seems to want to conquer Afghanistan, perhaps because its location is strategic. Wikipedia lists some 9 invasions (or 13 if we count each of both Britain and the Soviet Union’s three attempts separately).  Success is always temporary, as the most recent invaders have learned.  Geography in large measure explains why Afghanistan is so expensive to invade and conquer and why any conquests are temporary. The country consists of mountains, with fertile valleys between them where farming villages can thrive, and also of various deserts. Defenders can hide in their familiar mountains, attacking at will, and sooner or later the invaders withdraw.

It is timely, therefore, that there is METI focussed discussion of the detection of a tone from a source aligned with Proxima Centauri.  For background information about the “discovery” go here:

Imagining extraterrestrial life—from UFO sitings to the possibility of real intelligence— we pause to think. Some of us are afraid. Some truly want to see life outside of Earth. Some are oblivious. Like many, I really do not believe we are alone. How many galaxies are out there?  How many stars within those galaxies and how many planets circling those stars? I feel like it is egotistical to assume we are the only ones in the universe.

So, what if there is life?

He serves on the Advisory Council of METI International, the Advisory Board of Arch Mission Foundation, and the Board of Directors of the Society for Social and Conceptual Issues in Astrobiology.

Earlier this year, astronomers with the Breakthrough Listen project detected a narrow-band radio signal (BLC1) from the direction of Proxima Centauri. Scientists continue to verify and analyze data to determine whether BLC1 might be an intentional message from an extraterrestrial civilization.

Teaser: Rage, father-son conflict, and a distant husband launch Ad Astra, a science fiction action film.

The further we travel into outer space, the more we realize our most important connections are down here on Earth. That’s the message of Ad Astra, a science fiction action movie that doubles as a psychological study of deep space exploration and complex intimate relationships.

Carl L. DeVito is a member of the Emeritus faculty of the Department of Mathematics at the University of Arizona. Here he discusses his new book “Space, Life, Science and Stories: Our Recurring Interest in the Possibility of Cosmic Visitors”.

Some time ago an unusual book sold over 70 million copies and was translated to 28 languages. It claimed that aliens had come here and greatly influenced the development of humanity. This was just one of a number of surges of public interest in the possibility of our having cosmic visitors. Unfortunately, the scientific community rarely addresses the stories behind these surges and, when pressed, some among them respond with ridicule.

Multi-messenger astronomy is a hot ticket in science right now. Basically, it means observing the same astronomical target (or event) with different types of instruments. Some phenomena can produce flashes of light (visible with optical telescopes), radio bursts (collected by radio telescopes), and particle emissions (which show up in neutrino detectors and other instruments). Combining simultaneous observations from two or more instruments with different capabilities can help to reveal the true nature of strange things in the universe.
