This video about the scale of black holes will crush your poor, tiny brain
We thought we were prepared...
Black holes are vast, matter-annihilating objects that seem to defy physics by their very existence. They're so weird, that when Albert Einstein's equations first predicted the existence of these beasts, he didn't believe they could actually be real.
And you can't really blame him, because the idea that we have these singularities of space-time intent on sucking up all the matter around them scattered all around our cosmic backyard is pretty hard to wrap your head around.

Hello world! Sorry about the long time without any uploads,
but I had to spend some time dealing with life ;)
But good news, I am back with a space themed video similar to my first upload,
which became quite popular.
I hope I was able to convey my fascination.…

The North Pole is 20°C hotter than it should be right now
Temperatures near the North Pole are an unheard of 36°F (20°C) warmer than average right now, researchers have reported.
The Arctic is currently in the midst of polar night, where the Sun hardly ever rises. Usually, it’s the time when things get really cold and vast, thick ice sheets form for the winter.
But this year, temperatures are much warmer than usual – while the weather stations around the North Pole record the biggest difference, even in parts of Arctic Russia, temperatures are up to 12.6°F (7°C) warmer.And even though sea ice is forming again after reaching its annual low in September, it’s doing so much slower than usual.
In fact, so far the amount of ice coverage is even lower than the record-breaking low of 2012.
Scientists have taken to Twitter to express their concern over just how bad the situation is getting.

Astronomers have traced the source of the most powerful radio signal ever received from space
Scientists have observed the most powerful fast radio burst (FRB) ever – an intensely brilliant burst of radiation emanating from outside our own Milky Way galaxy.
The signal, which researchers say travelled at least a billion light-years to reach Earth, only lasted for a fraction of a second, but the observation could help us understand more about the epic gaps that exist between galaxies, called the cosmic web.
"FRBs are extremely short but intense pulses of radio waves, each only lasting about a millisecond," says astrophysicist Ryan Shannon from Curtin University in Australia. "Some are discovered by accident and no two bursts look the same."
There's a lot we still don't understand about FRBs and where they come from, partly because we've so far witnessed very few of them.
This new burst – called FRB 150807 – is just the 18th FRB detected to date since they were first discovered in 2001.
But despite this apparent rarity, scientists actually think these intensely powerful but short phenomena are happening all the time – we just don't notice them.

Plants ‘see’ underground by channelling light to their roots
A light-bulb moment? Plants seem to pipe sunlight directly down into underground roots to help them grow.
Light receptors in stems, leaves and flowers have long been known to regulate plant growth. Roots also have these receptors, but it has been unclear how they sense light deep in dark soil.
Hyo-Jun Lee at Seoul National University in South Korea and his colleagues used Arabidopsis thaliana – a small flowering plant from the mustard family – as a model to study this phenomenon.
They found that the plant stem acts like a fibre-optic cable, conducting light down to receptors in the roots known as phytochromes. These trigger the production of a protein called HY5, which promotes healthy root growth.

The surgeon behind the first human head transplant is using VR to prepare his patient
In case you haven’t heard the rumblings over the past year or so, Italian neurosurgeon Sergio Canavero is hell-bent on performing the world’s first human head transplant, and says the procedure will take place within the next 12 months.
He’s even got a willing participant - Valery Spiridonov, a 30-year-old Russian man with muscular atrophy - and Canavero has just announced that his patient will spend much of his preparation time inside a virtual reality machine to get him used to his new body.
If all of this is sounding to you like a terrible, horrible dream... we wish.
Last year, when Spiridonov announced his willing participation and progressed the project from 'Crazy surgeon speaking in hypotheticals' to 'Oh crap, this is actually happening' levels of weird.

European Mars Lander Crash Caused by 1-Second Glitch: ESA
PARIS — The European Space Agency (ESA) on Nov. 23 said its Schiaparelli lander’s crash landing on Mars on Oct. 19 followed an unexplained saturation of its inertial measurement unit (IMU), which delivered bad data to the lander’s computer and forced a premature release of its parachute.
Polluted by the IMU data, the lander’s computer apparently thought it had either already landed or was just about to land. The parachute system was released, the braking thrusters were fired only briefly and the on-ground systems were activated.
Instead of being on the ground, Schiaparelli was still 2.3 miles (3.7 kilometers) above the Mars surface. It crashed, but not before delivering what ESA officials say is a wealth of data on entry into the Mars atmosphere, the functioning and release of the heat shield and the deployment of the parachute — all of which went according to plan.

Cancer signalling pathway could illuminate new avenue to therapy
Researchers have better defined a pro-growth signaling pathway common to many cancers that, when blocked, kills cancer cells but leaves healthy cells comparatively unharmed. The study could establish new avenues of therapeutic treatments for many types of solid tumors.

Astronomers have found a whole new type of star at the centre of the Milky Way
Astronomers have discovered a new family of stars in the centre of the Milky Way, which they're calling N-rich stars, because of their unusually high levels of nitrogen.
Not only do these strange new stars deepen our understanding of what lies at the heart of our own galaxy, their discovery could shed light on how globular clusters - strange, spherical groups of stars that orbit the centre of a galaxy - formed during the creation of the Milky Way some 13.2 billion years ago.
