Why have some of our closest relatives retreated, whilst we have expanded everywhere? The clues are all […]

A look at two missions attempting one of the most difficult feats of space exploration – to collect a rock from another world. This episode checks in on the US and Japanese attempts to bring a piece of an asteroid back to Earth. The missions have taken decades of planning, but the results will be worth it.      We find out how studying these space rocks can teach us about the origins of our solar system and may one day help save Earth from a catastrophic collision.

A new age of space exploration, and exploitation, is dawning. But surprisingly, some of the boldest efforts at putting humans into space are now those of private companies started by a handful of maverick billionaire businessmen.     The 21st Century Race for Space Brian Cox gains exclusive access behind the scenes at Virgin Galactic, Blue Origin and Spaceport America, exploring what is really happening in privately financed space flight right now. From space tourism to asteroid mining, and even dreams of colonies on Mars, these new masters of the universe refuse to limit their imaginations. But are private companies

The Sky at Night – Return to the Moon ? –  Nearly 50 years ago, Neil Armstrong stepped onto the moon and it seemed like the dawn of a new age. Soon we’d be flying to the moon as effortlessly as we fly to America, and a moon base would be filled with men and women building a better future out in space. But then the moon fell out of fashion. We soon realized it was brutally inhospitable and getting there was eye-wateringly expensive.     Rather than spend huge sums of money going where we’d already been, Mars and

Space-time

How the Universe Works: Mystery of Space-time ep.10 2018

Science / 2 minutes of reading / / By

Space-time is the secret structure that controls the universe, and this strange four-dimensional substance controls time, light, and energy. It will also determine how the universe will end.       Space-time In physics, space-time is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Space-time diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur. Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe (its description in terms

Quasar

How the Universe Works: The Quasar Enigma ep.7 2018

Science / 2 minutes of reading / / By

Quasars are the brightest and most powerful objects in our universe, and though they have shaped the cosmos, they might ultimately destroy everything that exists.     Quasar   A quasar (also quasi-stellar object or QSO) is an active galactic nucleus of very high luminosity. A quasar consists of a super massive black hole surrounded by an orbiting accretion disk of gas. As gas in the accretion disk falls toward the black hole, energy is released in the form of electromagnetic radiation. Quasars emit energy across the electromagnetic spectrum and can be observed at radio, infrared, visible, ultraviolet, and X-ray

Science / 2 minutes of reading / / By

In October 2017, astronomers made a spectacular discovery – they spotted the first ever object to visit our solar system from outer space. They gave it a suitably exotic name… ‘Oumuamua. Its discovery set off a hurricane of press speculation and a major scientific investigation.     To investigate this spectacular astronomical detective story, The Sky at Night goes to Queen’s University in Belfast, which has become the centre of scientific research on this cosmic visitor. When they first spotted it, all scientists knew was that it was small, it was travelling fast, and it came from outside our solar
