Kilauea – Hawaii on Fire

Science, Nature / 2 minutes of reading / January 26, 2019 / By HDclump

In May 2018, Kilauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of local residents. It is Hawaii’s most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators? On the ground in the early days of the eruption, NOVA joins scientists and residents alike on a breathtaking journey to investigate Kilauea’s recent spike in activity. Along the way, some of Hawaii’s biggest secrets are revealed: Why did these geologically distinctive volcanoes form

Wonders of Life episode 3 – Endless Forms Most Beautiful

Science, Nature / 2 minutes of reading / January 25, 2019 / By HDclump

The universe is almost entirely devoid of life. Earth, the planet we call home, seems to defy the laws of physics. It is teeming with life in all colours, shapes and sizes. No-one knows for sure how many different species are alive right now, our best guess is close to 8.7 million. In this film, Professor Brian Cox asks how, from a lifeless cosmos ruled by the laws of physics and chemistry, it is possible that a planet can produce so much wonderful, varied biology. It’s an epic journey through time that begins with Brian undertaking a species

Wonders of Life episode 2 – Expanding Universe – Professor Brian Cox encounters the astonishing creatures that reveal how the senses evolved. Every animal on Earth experiences the world in a different way, using a unique suite of senses to detect its physical environment. Tracing the evolution of these mechanisms is a story that takes us through life’s journey – from single-celled organisms to more complex, sentient beings. Brian finds that over the course of 3.8 billion years, the senses have driven life in new directions and may, ultimately, have led to our own curiosity and intelligence. Brian

The Sky at Night – Beyond Pluto: On 1st January 2019, Nasa’s New Horizons probe notched up another historic first: the first ever Kuiper belt fly-by. Its target was 2014 MU69, a chunk of ice and rock about four billion miles (approximately 6.4 billion kilometres) from Earth, dubbed Ultima Thule, a Latin phrase meaning a distant, unknown region. It is the most distant fly-by in history, and it is believed the data New Horizons gathers will shed new light on the solar system’s early days. Chris Lintott reports from the John Hopkins Applied Physics Laboratory in Maryland to bring the

The Story of 1

History, Science / 2 minutes of reading / January 13, 2019 / By HDclump

The Story of 1 is a documentary about the history of numbers, and in particular, the number 1. It was presented by former Monty Python member Terry Jones. Terry Jones first journeys to Africa, where bones have been discovered with notches in them. However, there is no way of knowing if they were used for counting. Jones then discusses the Ishango bone, which must have been used for counting, because there are 60 scratches on each side of the bone. Jones declares this “the birth of one”; a defining moment in history of mathematics. He then journeys to

How the Universe Works episode 1 2019: Nightmares of Neutron Stars

Science / 2 minutes of reading / January 10, 2019 / By HDclump

Neutron stars are strange and violent phenomena that defy the laws of physics, and new discoveries reveal that these bizarre nightmares are far more deadly than previously believed, with the power to destroy planets and even other stars. A neutron star is the collapsed core of a giant star which before collapse had a total of between 10 and 29 solar masses. They are the smallest and densest stars, not counting hypothetical quark stars and strange stars. Neutron stars have a radius of the order of 10 kilometres (6.2 mi) and a mass lower than 2.16 solar masses.

Mass Extinction: Life at the Brink

Science / 3 minutes of reading / December 23, 2018 / By HDclump

It’s death on an unimaginable scale, when a majority of Earth’s species quickly die out. It’s called “mass extinction,” and it’s happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a man-made mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.

In Human Universe episode 5: Professor Brian Cox concludes his exploration of our place in the universe by asking what next for the ape that went to space. In northern Spain, he begins in a cave that was once home to our distant ancestors. Here, he discovers some of the earliest art in the universe – a child’s hand painted onto the wall that has remained intact for around 40,000 years. That child – if raised today – would be just as bright and just as capable as any modern child. Yet its vision of the future would be very
