Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky. In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result.
Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive, and relatively expensive to run.
In the past few decades, there has been an explosion in the number of extra-solar planets that have been discovered. As of April 1st, 2018, a total of 3,758 exoplanets have been confirmed in 2,808 systems, with 627 systems having more than one planet. In addition to expanding our knowledge of the Universe, the purpose of this search has been to find evidence of life beyond our Solar System.
Popular science fiction of the early 20th century depicted Venus as some kind of wonderland of pleasantly warm temperatures, forests, swamps and even dinosaurs. In 1950, the Hayden Planetarium at the American Natural History Museum were soliciting reservations for the first space tourism mission, well before the modern era of Blue Origins, SpaceX and Virgin Galactic. All you had to do was supply your address and tick the box for your preferred destination, which included Venus.
Researchers took a look at the third Gaia space telescope data release. They uncovered several exciting phenomena, including evidence for a significant event that took place relatively recently in our home galaxy. Moreover, astronomers were able to clearly observe our home galaxy's outer side for the first time.
Flowing rivers are probably not the first thing that comes to mind when thinking of Greenland and its seemingly endless amount of frozen vistas. Nonetheless, scientists uncovered that there might be a substantially large one underneath the surface, flowing from deep in its interior all the way to the northeastern coast.
You might not have given it any thought before, but the strength of someone's handshake can provide you with more information than you might think. It turns out that grip strength is a good indicator of a person's health and genuine physical age. Moreover, a weaker than average grip can be an indicator of several hidden health issues.
here are many commonly-held misconceptions about how our brain works and how we learn. A catchy example is perhaps the belief that some of us are right-brained and others left-brained, where left-brained people are supposed to be better at mathematics while left-brained people are more creative. These misconceptions are sometimes referred to as 'neuromyths.'
