Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms. These metabolisms raise the possibility of Ven...
We propose a mechanism to explain the low-frequency QPOs observed in X-ray binary systems and AGNs. To achieve this, we perturbed stable accretion disks ar
The model can also show how dark energy is not an increase in energy that is causing the accelerated expansion of the universe, but is an accelerating decrease in matter throughout the universe as the stars and galaxies in the universe continue to convert matter into energy during their life ...
Although we tend to think of it as a vacuum, it's not completely empty. There's radiation zipping through it (there must be—how else would we see all those distant stars and planets?), meteorites nipping past, "cosmic dust," and even bits of space junk (broken bits of satellites ...
The comic feigns that these artifacts are real spikes of stellar matter extending from the stars being viewed. The spikes have sufficient energy and coherence to slice planets that intersect them, rather than merely bludgeon or vaporize them. Additionally, they appear to nullify gravity - preventing...
Carbon nanostructures seen in circumstellar envelopes surrounding carbon-rich stars could have a chemical origin with soot particles created during fuel combustion. Image Credit: Shutterstock.com/ lucadp According to KAUST researchers, each process could be based on the same reaction mechanism. The su...
It takes some effort to see the depth in what at first seems to be a random dot pattern. Not everyone can do that on the first try. There are lots of resources online which teach how to do that. The good thing is it's like riding a bicycle: once you got it right for the first...
have been unambiguously identified as the mechanisms that cause such a unique jet kink behaviour. We show how the toroidal magnetic field embedded in the supersonic jet triggers plasma instabilities and results in considerable deflections throughout the jet propagation, mimicking the kinks in the Crab...
And by better understanding white dwarfs, Miller believes we potentially could better understanddark energyand how fast it causes the universe to accelerate. "At the moment, when measuring distances, we treat all of these explosions as the same, yet we have good reason to believe that there are...
