Speed of Light – See how torturously slow it is

The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times […]

There is most probably no Kardashev Type III civilization in the Universe. Here’s why

In 1964, Russian astrophysicist Nikolai Kardashev (born April 25, 1932) defined three levels of civilizations, based on the order of magnitude of power available to them (known as the Kardashev scale):

10 Amazing Facts about Space

Watch: The Milky Way as You’ve Never Seen It Before

In April 2018, the European Space Agency’s Gaia observatory released its second data catalog, which includes the distances to over 1.3 billion stars. In the video published by the American Museum of Natural History, museum’s astrophysicist Jackie Faherty breaks down why this information is so revolutionary and explains how this information is helping scientists and non-scientists […]

There are more microbial species on Earth than stars in the galaxy

For centuries, humans have endeavoured to discover and describe the sum of Earth’s biological diversity. Scientists and naturalists have catalogued species from all continents and oceans, from the depths of Earth’s crust to the highest mountains, and from the most remote jungles to our most populated cities. This grand effort sheds light on the forms […]

Top 6 Biggest Stars in the Universe

What is the biggest star in the Universe? In fact, it is really hard to give an exact answer to this question since the universe is big, neighboring and the other galaxies are billions of light-years away from us. But, we can give it a try. Here are the top 6 biggest stars in the Universe […]

Watch: what other stars would look like in the place of the Sun

The Sun is the primary source of energy for Earth’s climate system, and the life on Earth. With a diameter of about 1.39 million kilometers (864,337 miles, i.e. 109 times that of Earth), and a mass about 1.9885×1030 kg (330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar […]

ESA’s Gaia has Created the Most Detailed Map of the Milky Way

ESA’s (European Space Agency) Gaia spacecraft has created the most accurate and detailed map of the Milky Way galaxy (and beyond) to date. The map includes high-precision measurements of nearly 1.7 billion stars and reveals previously unseen details of our home Galaxy. It is the second iteration of the map and published by ESA on […]

Exoplanet Travel Bureau by NASA – Interactive 3D Images

Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand … (insert a hundred or a thousand grands here) children can stand on an exoplanet’s surface someday. But, we don’t have to wait. NASA has opened a new web page, an “Exoplanet Travel Bureau”, and we can, at […]
