How many great minds does it take to invent a telescope?

On 11 January 1672, the Fellows of the British Royal Society were treated to a demonstration of Isaac Newton’s reflecting telescope, which formed images with mirrors rather than with the lenses that had been used since the time of Galileo. Afterward, the fellows hailed Newton as the inventor of this marvelous new instrument, an attribution […]

Solar Panels work by absorbing LIGHT from the sun, not heat

Ignorance is a very, very bad thing. Last week, as North America suffering from extreme cold weather because of a phenomenon called “polar vortex“, Jim Hoft, founder of the American far-right news and opinion website The Gateway Pundit has tweeted that: “It’s a bit cold outside this morning in middle America… Aren’t you glad you […]

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 […]

Astronauts demonstrate Newton’s second and third laws of motion

A microgravity environment is a perfect place to demonstrate basic physics, i.e. Newton’s laws of motion. In the videos published by the NASA Johnson channel, astronauts aboard the International Space Station (ISS) just do that.

10 Amazing Facts about Space

The endless depths of the sky intrigue almost all humans alike. Space is like an abstract dream coming to life when it unfolds into a number of unseen horizons. The enormous nebulas, staggering hypernovae and the smattering of countless planets and stars make it a canvas of muse. We are but a speck of dust […]

What is the mass of the Earth? Scientists used neutrinos to measure

While scanning the interior of Earth using neutrinos, a team of scientists from Spain also used these subatomic particles to measure the mass of the Earth. Their result is in agreement with the current best estimate, which was measured using the value of the gravitational constant (G).

The coldest place in the Universe is now on the ISS

As soon as NASA’s Cold Atom Laboratory (CAL) began producing ultra-cold atoms, the International Space Station (ISS) became the coldest place in the known universe. The formation of a Bose-Einstein condensate, a fifth state of matter occurred in NASA’s Cold Atom Laboratory (CAL) at a temperature of 130 nanoKelvin, or less than 10 billionth of […]

Soon, the ISS Will Be the Coldest Known Place in the Universe

Where is the coldest known place in the Universe? It may sound strange, but today, it is here on Earth: in 1995, in a laboratory in M.I.T. (Massachusetts Institute of Technology), the German physicist Wolfgang Ketterle and his colleagues have cooled a sodium gas to the lowest temperature ever recorded, only half-a-billionth of a degree […]
