The Star Garden
The Star Garden is a popular science website run by Dr Helen Klus. This is shown in a timeline of the universe.
It contains science news and educational articles that cover the history of physics from prehistoric times to the modern day. The books in the popular science series How We Came to Know the Cosmos by Dr Helen Klus are available to read for free on The Star Garden. The How We Came to Know the Cosmos series describes complex modern theories like quantum mechanics and general relativity from first pr

Pseudoscience, ethics, and meaning: The relationship between philosophy and science http://www.thestargarden.co.uk/Why-science-needs-philosophy.html
Pseudoscience, ethics, and meaning: The relationship between philosophy and science Science has a massive impact on everyone. How we teach it, and what we decide to fund, can literally have life and death consequences for millions of people.
The planet Earth: http://www.thestargarden.co.uk/Earth.html
The Planet Earth Earth is the third closest planet to the Sun, and completes one orbit every 365 days. Earth is larger, denser, and more massive than Mercury, Venus, and Mars.
From Salvador Dali to Monty Python: Artists inspired by science http://www.thestargarden.co.uk/Science-in-art.html
From Salvador Dali to Monty Python: Artists inspired by science Artists don't have to disregard their bias, and so can use art to evoke emotional responses to scientific ideas, forcing us to consider how we feel about them.
The planet Venus: http://www.thestargarden.co.uk/Venus.html
The Planet Venus Venus is the second closest planet to the Sun. It takes about 225 days to orbit the Sun, and less than a single day passes on Venus during this time.
Gravity, weight, and mass: How to weigh objects in space http://www.thestargarden.co.uk/How-to-weigh-objects-in-space.html
Gravity, weight, and mass: How to weigh objects in space Everything with mass produces a gravitational field, which causes things to accelerate towards it. The gravity on the surface of the Earth is about 9.8 ms-2.
The planet Mercury: http://www.thestargarden.co.uk/Mercury.html
The Planet Mercury Mercury is the closest planet to the Sun. Mercury takes about 88 days to orbit the Sun, and only about 1.5 days go by on Mercury during this time.

Robot Dreams: Artificial neural networks and Google's Deep Dream In order to gain a better understanding of how Google's artificial neural network works, software engineers got it to draw what it thought a banana looks like.
Black Holes: http://www.thestargarden.co.uk/Black-holes.html
Black Holes After a supernova, the most massive stars can’t even be held together by neutron degeneracy and collapse in on themselves, becoming black holes.

S*x and gender: Pioneering transgender and genderqueer scientists Many scientists used to think there are only two genders, and that a person's gender is determined from their ge****ls. We now know that this is not the case.

Cycles of destruction: The link between comet and asteroid impacts and mass extinctions on Earth http://www.thestargarden.co.uk/Cycles-of-destruction.html
Cycles of destruction: The link between comet and asteroid impacts and mass extinctions on Earth Mass extinctions appear to occur in cycles, caused by comets hitting Earth. This may be due to Planet X or a disc of Galactic dark matter.
The Origin of the Universe: http://www.thestargarden.co.uk/Big-bang.html
The Origin of the Universe It is currently accepted that the universe came into existence about 14 billion years ago, in the big bang. This was proven in the 20th century.
