How Does The Human Body React to Being in Space?

How Does The Human Body React to Being in Space? Introduction Following on from Issue 19 which looked at the International Space Station (ISS) and Tim Peake’s life and work on it1, this article aims to look into the fundamental ways that an astronaut’s biological systems change in space, down to the level of their […]

What is Hawking radiation and what problems has it brought to physics?

Gale, Cengage Learning

A black hole is a region in space-time where the gravity is so strong that nothing can escape; not even light (which is why they appear black). That is why, when Stephen Hawking found a theoretical argument for the existence of a type of black hole radiation, it took the scientific world by storm. This, […]

Europa Latest – Jupiter’s Moon Reveals More Exciting Secrets

NASA/JPL-Caltech

On Monday 26 September, NASA announced that it has discovered ‘surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa’. This evidence is in the form of UV images captured by the Hubble Space telescope, which suggest that there might be water jets that are emanating from ‘cryogeysers’ […]

Jim Al-Khalili Interview

Jim Al-Khalili Interview

Young Scientists Journal was fortunate to interview Jim Al-Khalili, a prominent science communicator and Professor of Theoretical Physics at the University of Surrey. Laura Patterson, from the King’s School YSJournal hub, went down to Surrey to talk to him about his work in physics and science communication. Jim has presented several science documentaries and radio […]

Lunar Mission One – An Introduction

LM1Pic

“Lunar Mission One is the most inspirational Moon project since the Apollo landings. Funded by the public it will perform world-leading science into the origin of the Moon and the planets, and it will leave a permanent archive of human life buried at the Moon’s south pole.” (lunarmissionone.com) Up until now, space exploration has been […]

How to Become an Astronaut

Major Tim Peake became only the second British person to become an astronaut when he was launched into space on board the Russian made Souz TMA-19M rocket on the 15th of December 2015 sparking a frenzy of British media coverage and interest in space travel. What must an astronaut-to-be learn?   Whilst Tim Peake is […]

Exobiology – The Hunt for Extra-Terrestrial Life

Martian Soil

This article discusses astrobiology, the study of life within the universe. Here, the origins of life within the universe are considered and the most likely celestial objects, in which humans may encounter life, are examined.

The Hunt for the Higgs

Physics tries to answer some of the most fundamental questions in the universe. What caused the Big Bang? Why is the observable universe so isotropic? Why is Earth able to nurture life? One important question that has mystified physicists for years is the idea of mass and more importantly its origins. The discovery of the […]

The Superstring Theory

In this article, Daniel Fryday from St Mary’s Catholic School in Bishops Stortford, gives you an introduction to the Superstring Theory. The Superstring Theory is a way in which scientists attempt to explain all of the fundamental particles and forces of nature. The Superstring Theory is an idea that explains how our universe is just […]

What is the ISS?

On the 15th of December 2015, British Astronaut Tim Peake boarded the International Space Station for ISS Expedition 46 and 47. His mission has been named ‘Principia’, a reference to Isaac Newton’s ‘Philosophiæ Naturalis Principia Mathematica’ in which Newton writes about the laws of motion, universal gravitation and various other laws of physics. A direct […]

Basic rocket propulsion

Newton stated in his third law that every action must have an equal and opposite reaction. This has proved extremely useful for rocket propulsion as the law demonstrates that if a large amount of fuel is rapidly ejected from the back of a vessel it is quite clear that there is a large force acting […]

Interview with Lord Rees

Lord Rees and CN (3)

  On the 10th of March YSJ Editorial Team Leader, Claire Nicholson, interviewed current Astronomer Royal, Martin Rees. Martin Rees is not only a Professor of Astronomy at Cambridge but also a member of the House of Lords. He is also a former President of the Royal Society. Martin told YSJ that being President of the Royal […]

Into Space without Rockets

Fig. 4: Space Elevator. Available from; http://en.wikipedia.org/wiki/Space_elevator

Into Space without Rockets Sansith Hewapathirana Nunthorpe Academy, Middlesbrough Abstract In this so-called space age the current method of space travel, rockets, is hugely prohibitive in cost. There are several possible ways with which we can truly embark into space. Including space elevators, launch loops, and space guns. This paper aims to update you on […]

Science Bites

sci bites cover final big

For a few months now, I’ve been working on my eBook – Science Bites. Tomorrow it reaches the Amazon Kindle Store for £1.51. The idea behind the eBook was to make science fun and interesting – by using small, manageable pieces of information.  The eBook is about 180 pages long and covers topics from life […]

Birth of Saturn’s Moon Witnessed

_74282294_74282293

Sorry for not posting in a while – we’ve been plagued with computer issues!   Scientists say they have potentially witnessed what they believe could be the birth of Saturn’s 63rd Moon.  The probe Cassini has taken a black and white image of Saturn’s outermost ring which is believed to hold the evidence. It’s such […]

Cosmic ‘web’ seen for the very first time

cosmic

The hidden tendrils of dark matter that can unlock hidden secrets of the universe may have been traced for the very first time. The Cosmology theory predicts that every galaxy is embedded in a cosmic web is “stuff”. Most of which, scientists believe is dark matter. Astronomers obtained these first direct images by using the […]

A Sense of Scale

Star Sizes

From sub-atomic to Universal, the range of scale tends towards infinity – in both directions. It could be argued that the small can be imagined as our minds can attempt to grapple with the concept of nothing and then it is only a case of imagining something getting infinitesimally closer to that limit. Yet with large scale we become stuck – viewing from or within a constricted radius of planet Earth it is difficult to put scale into perspective. We quickly lose our ability to compare the large with the larger which soon appear to be both insignificantly small in comparison to the larger still. This article helps rebalance scale. What you once thought big, you’ll think big no longer.

The Aurorae

Red_and_green_auroras AURORAE

The Aurora Borealis and Aurora Australis are one of the world’s seven natural wonders and have left men in awe for generations. This article investigates the causes of The Aurorae, the causes of the different colours and investigates Auroras on other planets such as the Jovian Aurora on Jupiter.
