New research suggests that the famous black hole Cygnus X-1 – first black hole ever detected and one of the closest to Earth – is farther away and much more massive than previously believed.
To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres.

(University of Oregon) Friction caused by dry Martian dust particles making contact with each other may produce electrical discharge at the surface and in the planet’s atmosphere, according University of Oregon researchers. However, such sparks are likely to be small and pose little danger to robotic or human missions to the red planet, they report in the journal Icarus.
Until recently, magnetic fields in the outskirts of galaxies were too faint to be detected. Although it’s still not clear what causes them or how they’re maintained, astronomers have started to create images of their observations of galaxies’ magnetic fields producing beautiful aurora-like effects. See them here.
A new study shows a link between climate change and an earlier and longer allergy season. That’s something that Dr. Joshua Jacobs, medical director at Allergy and Asthma Clinical Research, which has locations across the East Bay, said he’s certainly…
Physicist Avi Loeb of Harvard believes we should take seriously the idea that ‘Oumuamua – the 1st known object to pass through our solar system from interstellar space – might have been created by an alien civilization. His new book is called “Extraterrestrial.”
