Animated gifs are a great way to show off a variety of subjects. Space is no exception. In a recent Twitter animation, planetary scientist James O’Donoghue from the Japanese Aerospace Exploration Agency (JAXA) shows us how Earth, our solar system and the galaxy are moving through space at different speeds. The Sun The Sun is…
Spaceflight Simulator is a fun simulation game to build your own rockets and send them to outer space. Developed by Stefo Mai Morojna, this game has real-life physics to let you participate in fascinating space exploration. The Sun, known as Sol in Spaceflight Simulator, is the star that Earth and all of the planets orbit….
Our Solar System is a collection of planets, moons and dwarf planets that orbit the Sun. The planets range in size from the rocky Earth to the gaseous Jupiter. The Solar System also contains a large number of comets, asteroids and other small objects that fall into the system from outer space. Many of these…
Bluetooth has become a ubiquitous technology in today’s digital world. From smartphones to smart home gadgets, it’s the most common way electronics communicate wirelessly. It works by sending short bursts of information over radio waves, at a frequency around 2.4 GHz. That’s the same frequency used by WiFi routers, but Bluetooth uses far less power…
The human unique is a term used to describe the characteristics that make humans different from other animals. These features include language, tools, culture and consciousness. One of the most obvious ways that humans are different from other primates is our ability to reason and solve problems. This is because of our highly developed brain…
Solar energy is one of the most popular forms of renewable power, but many people wonder if solar panels take up a lot of space. The answer depends on a variety of factors, including your roof and the efficiency of the panels you use. Generally, solar panels take up much less space than you might…
Robots can be programmed to follow a set of rules that prevent them from harming humans and allow for their continued operation. These laws were created by sci-fi author Isaac Asimov in his short story “Runaround” and are commonly referred to as the Three Laws of Robotics. While these laws are a powerful concept, they…
Most solar systems have only one sun, and this is because the Sun is just too massive to support life. However, it is possible for a planet to orbit two suns. Scientists have found that such worlds can retain their water vapor for long periods, making them a suitable habitat for life. The findings suggest…
Over the past millions of years, human evolution has been driven by natural selection. But new research suggests that climate-driven ecological changes may have also shaped key events in our evolutionary history. This theory, called variability selection, suggests that environmental instability was the driving force behind key developments in our ancestors’ lives. This could have…
