“Beautiful and Dangerous Physics” -First Wolf-Rayet Star System to be Discovered in the Milky Way

 

Astronomers discovered “a ringside seat into beautiful and dangerous physics that we have not seen before in our galaxy. This is the first such Wolf-Rayet star system to be discovered in our own galaxy,” explains Joseph Callingham of the Netherlands Institute for Radio Astronomy (ASTRON), lead author of the study reporting this system. “We never expected to find such a system in our own backyard.”

Planets Unlike Any in Our Solar System

TOI-270 Star System

 

“The tiny star TOI-270 (less than half the size and temperature of our Sun) hosts one super-Earth and two sub-Neptunes. In our solar system, there is absolutely nothing that resembles such intermediate planets, with a size and composition somewhere in the middle of Earth and Neptune (4 Earth radii); we directly jump from rocky worlds (like Earth) to gas-dominated worlds (like Neptune),” astrophysicist Maximilian Gunther, an ESA Fellow at the European Space Research and Technology Centre (ESTEC), told The Daily Galaxy.

Astronomers Probe the Dark-Matter Backbone of the Universe

fuzzy dark matter backbone

 

“The first galaxies in the early universe may illuminate what type of dark matter we have today,” says Mark Vogelsberger, associate professor of physics in MIT’s Kavli Institute for Astrophysics and Space Research about one of the great mysteries of modern physics. “Either we see this filament pattern, and fuzzy dark matter is plausible, or we don’t, and we can rule that model out. We now have a blueprint for how to do this.”

The Extraterrestrial-Contact Paradox 

ESO Observatories Chile

 

British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. Although intelligent life is inevitable, we will never find it -at least not by searching in the Milky Way. Wolfram points out that in order to compress more and more information into our communication signals – be they mobile phone conversations or computers – we remove all redundancy or pattern. If anything in a signal repeats, then it can be deleted. But this process of removing any pattern from a signal makes the signal look more and more random – in fact, pretty much like the random radio “noise” that rains down on Earth coming from stars and interstellar gas clouds.

The Extraterrestrial Signal -We May Not Want to Receive

Is there a fundamental flaw in why we have not received a signal from an advanced alien civilization? How do we decode an alien message –alien is alien so it might be impossible. What if they communicate chemically? Will they use the language of math and science signaling at 1420 megahertz? What if we are too primitive to comprehend a message or the technology of its signal that may exist in a form beyond matter? What if it’s a message from an extinct civilization astrophysicist such as Harvard’s Avi Loeb believes exist in our galaxy? Or, as John Gertz suggests for Scientific American, maybe the aliens are already in our solar system, probably in the form of robotic probes.
