Encounter with Jupiter

Pioneer was the first spacecraft to return pictures and data from the largest planet in the solar system, with both Voyager missions following in the 1980's. These missions enhanced the knowledge known about the Giant Red Spot as well as the rest of the atmosphere, possibilities of life being found on the planet, its magnetic field and faint ring, and the formation and features of the moons Callisto, Europa, Io, and Ganymede.

Encounter with Neptune

Voyager 2 made it all the way out to Neptune in 1989 and immediately began imaging the planet and its moon Triton to learn more about them. Upon arriving and studying Neptune, scientists discovered that it is a strange planet with more activity than expected, including high-speed winds in the Great Dark Spot, three faint rings around the planet, and other small moons found in orbit.

The Russians in particular sent a number of probes to the planet, and landed on the surface, though these had to contend with the enormous pressures and heat. The Americans also got involved with NASA's launch of Magellan in 1989 which orbited the planet for analysis, and discovered a strange surface.

Flight 587

Flight 587 was an Airbus A300 leaving John F. Kennedy Airport, New York to Las Américas International Airport, Santo Domingo, just two months after the 9/11 terrorist attacks. The plane crashed less than two minutes after take-off in the suburban neighbourhood of Belle Harbor and immediately, the conclusion was that the cause had to be terrorism though the NTSB investigation soon revealed the true cause.

Global Dimming

Scientific studies are suggesting that we have underestimated the speed of climate change, with the effect of global dimming. In the immediate aftermath of 9/11, scientists discovered the possibility that water vapour trails left behind by now grounded aircraft have a large impact on the climate. As air pollution is reduced through technology, this could mean a big increase in the rate of climate change previously unaccounted for.

Global Village

Global Weirding

The weather appears to be becoming more extreme all over the planet which has lead to some scientists coming up with the term 'Global Weirding'. Starting with the increasing power of hurricanes in the Atlantic, as well as a devestating drought and dust storms in west Texas, the changes will also affect Britain as longer, drier spells are predicted alongside significant flooding due to increasing rainfall.

Helike, The Real Atlantis

The search for the lost Greek city of Helike has been likened to a real Atlantis. Supposed to have existed over two thousand years in the past, Helike was a large city which was apparently disappeared over the night, with theories positing that an Earthquake destroyed the city. However, what caused the city to vanish is up for debate as some believed it was swept into the sea, while others suggest liquefaction caused it to be buried under a lagoon.

Hello Universe!

Here Be Monsters

With the launch of the Hubble Space Telescope in 1990, and other instrumentation, science is beginning to prove theories about the start of the universe, and how galaxies and stars are formed. Starting with Edwin Hubble's work, the continuing scientific study discusses the merging of galaxies and the formations of black holes, and looks at what we know and don't know about the hidden centres of them.

Killer Algae

A small plant discovery in California lead to concerns of biologists, which has been termed 'Killer Algae'. The highly invasive water plant was found in a lagoon, with fears that it could spread to the Pacific Ocean, and on to devestate the oceans eco-systems. Named Caulerpa taxifolia, it is a tropical plant which was first found in the Mediterranean Sea in 1984, and has since been discovered in other odd locations.

Killer Lakes

At Lake Kivu in Rwanda, West Africa, there is a significant danger to the people living nearby which has killed previously. With the mysterious death of thirty-seven people at Lake Monoun in Cameroon and a much larger incident involving people and animals at Lake Nyos, scientists begin to investigate what could have caused deaths which looked very much like asphyxiation, and how they can be prevented from happening again.

Solar Storms: The Threat to Planet Earth

With the Sun becoming more active, and that increases the risk of solar storms hitting the Earth with the effect of bringing modern life to a standstill. In 1989, Quebec was hit by a solar storm and suffered a major power failure providing a hint of the potential problems - the most vulnerable of which are satellites and electrical systems - leading scientists to study how they can predict the next one.

Strange Signals from Outer Space!

The chances of an advanced civilisation being discovered in space is considered to be large due to the vast size of the universe, however the lack of communication provides support currently for the opposite. The discovery of a massively powerful signal leads to questions as to whether we are about to find that civilisation, though the science has problems with the strength of the signal indicating a super-advanced society.

Taking a look at aircraft crashes and the chance of survival, the aviation safety industry is looked at to find out the best scenarios for surviving. A number of previous accidents are analysed to find out how passengers can reduce injuries during a high-speed impact, survive after ditching into water, where the safest seat on a plane is, how to evacuate safely and what to do in smoke-filled conditions.

Swallowed by a Black Hole

Swallowed by a Sink Hole

In Florida, a 2013 sinkhole claimed the life of Jeff Bush in his own home as his bedroom floor collapsed into a forming chasm. Geologists are investigating the phenomenon which can cause quick-forming holes in the soft limestone rock, which is prone to dissolving when it meets with water. Also occurring in a number of places around the world, the number of sinkholes in Florida has made it almost impossible to count them.

Climate Change models have predicted that Britain's weather may become more Meditteranean, though suggestions also indicate this to be wildly wrong, and it may have more similarities with Alaska. Scientific studies are looking at how quickly climate jolts can occur with evidence pointing to changes in the Gulf Stream. This is reckoned alongside the impacts of the average temperature on Earth rising over the next century.

Scientists are investigating how long the oceans can continue to cope with the pressures of commercial fishing and ocean acidification, as life in the ocean continues to dwindle. Due to the influx of new technologies to catch fish such as sonar and factory ships, studies are predicting that fish stocks of the oceans will collapse by 2050, though there have been some improvements in places were measures have been taken.

The Death Star

Until recently, humans were unable to observe as far back as the beginning of the universe. However, belief that the Soviets were testing nuclear weapons on the far side of the moon during the cold war cold war lead to the discovery of gamma-ray bursts believed to be eminating from the edge of the universe. However, the hypothesis proved tricky to accept with the threat of Einstein's Mass-energy equivalence being proved wrong.

Uranium Goes Critical

An increase in the mining of Uranium raises questions about how long we have until resources are depleted. As its use in energy production has increased significantly, the supplies are struggling to keep up with anticipated demand, for a material which was once more heavily used in glassware and pottery. However, its potential as an efficient energy source was discovered with Fermi's experimentation with the material.

Uranus Encounter

Voyager 2 paid a visit to Uranus in 1986 to build on the little previous knowledge about the planet that was known. Discoveries were made about its atmosphere composition, ring structure, and orbiting satellites. The results of the trip also raised a number of questions such as how its moon Oberon came to have a large mountain-like structure, while Titania has large rifts on the surface of what is believed to be an icy body.
