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, the fifth state of matter occurred in NASA’s Cold Atom Laboratory (CAL) at a temperature of 130 nanoKelvin or less than 10 billionths 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 …

The hottest place in the Universe exists on Earth

The hottest place in the Universe exists here on Earth, like the coldest place in the Universe. Both these extreme temperatures are not natural, they are human-made. The coldest temperature was achieved in the German physicist and professor of physics Wolfgang Ketterle’s laboratory at the Massachusetts Institute of Technology (MIT). The hottest temperature, also recognized …

LIGO detects gravitational waves from neutron star merger

On October 16, 2017, for the first time ever in history, scientists were able to detect gravitational waves from two neutron stars’ merger. Carl Sagan’s famous quote says “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing …

Why do we see only one side of the Moon?

You have probably heard references been made to the “dark side” of the Moon – there’s even a Pink Floyd album with that name. But, in fact, there’s no “dark side” of the moon. Because our satellite is not illuminated by the Earth, it is illuminated by the Sun. All the surface of the moon gets lit by …

Why do astronauts float in space?

We see images and videos from the International Space Station (ISS) where astronauts float in space freely. That’s because they’re in space, so there is no gravitational force of Earth there, right? Wrong. The International Space Station is in Low Earth Orbit (see notes 1) with an altitude of between 330 and 435 km (205 …

Leaving the Solar System at the Speed Of Light

What if we could make a spaceship that is capable of leaving the solar system at the speed of light? How much time would it take to enter interstellar space? Our Solar system is big, and vast, despite it being really small compared to our galaxy, not to mention the complete universe. To put this …
