Prospecting for interstellar oil
Posted by Shubham Ghosh Roy in categories: chemistry, cosmology
We have developed a new method to look for carbon compounds in space, akin to prospecting for oil on Earth. Our method is published in Monthly Notices of the Royal Astronomical Society.
Between the stars lie vast amounts of interstellar gas and dust, spread thinly throughout our galaxy. The dust can contain compounds of carbon. When it does we call it carbonaceous interstellar dust. This is an important reservoir for the organic material in space. The continual cycle of material between the stars and the gas in the interstellar medium in our galaxy leads to the delivery of organic molecules to newly forming planetary systems.
A special sub-class of organic molecules called prebiotic molecules are thought to play a major role in the formation of life on Earth. Such prebiotic molecules are likely preserved in carbonaceous interstellar dust that are gathered together in planetesimals, in an early stage of planetary formation. The chemical composition in such environments may determine the planet’s hospitality to the formation of life there. Therefore, it is important to understand the life cycle of carbonaceous interstellar dust to study this possibility further.

Black Holes are amongst the most destructive things in the Universe, but it may be that properly utilized, they might be the best places in the galaxy to live around in the future, and possibly right here in our own solar system too.

Good news, universe! Scientists are one step closer to finally understanding dark matter
Posted by Gemechu Taye in categories: cosmology, particle physics
Dark matter is made up of axions, elementary particles that are full of suspense.
About 85 percent of our universe is believed to be composed of dark matter, a hypothetical material that does not interact with light. So it neither reflects nor emits nor absorbs any light rays, and therefore, we can not see this unusual form of the matter directly. However, to understand and explain the nature of dark matter, scientists have created various models.
