The origin of life remains a great mystery in biology. Continental drift has erased most of the record, until all that's left of the first half billion years of evolution are some millimeter…

Large stars go supernova but smaller stars sometimes end up as planetary nebulae – colorful, glowing clouds of dust and gas. These nebulae have been observed to often emit powerful, bipolar jets of…

Though the evidence shows that people are not really different during a full moon, like homeopathy or organic food benefits happen just often enough that people are convinced by the placebo/nocebo…

You've probably seen movies of orbital space habs spinning for artificial gravity. But did you know, that nobody has ever tested this to see how it works out in practise? We know that weightlessnes…

The origin of life remains a great mystery in biology. Billions of years of continental drift erased most of the record, and all that's left of the first half billion years of evolution are some…

Stars like Sol are relatively easy to understand, because they are numerous, and live for billions of years, but high mass stars are rare and live for only a few million years. As a result,…

In 2005,the Japanese spacecraft Hayabusa  revealed that the near-Earth asteroid (25143) Itokawa  has a strange peanut shape, leading to questions about why. Now, using ground-based…

Kepler-413b is located 2,300 light-years (about 700 parsecs) away in the constellation Cygnus. It circles a close pair of orange and red dwarf stars every 66 days but what really makes Kepler-413b…

In my article Our Spacecraft Could Look Straight At an Extraterrestrial Microbe - And Not See a Thing! we found out that present day extraterrestrial microbes in our solar system would be sparse and…
