HALLEY’S COMET DARK UNIVERSE
NORMAL MATTER 5%
One of the most surprising discoveries of the last century is that normal matter, which makes up the stars, planets, and all living things, amounts to less than 5% of the Universe. In the 1970s and 1980s, a number of observations revealed that the mass of observed normal matter in the Universe was insufficient to explain the existing forces of gravity within and between galaxies. Stars on the outskirts of galaxies move much faster than what would result from the attraction of the observed matter alone. Furthermore, the CMBR provides support for the concept of a special form of matter that does not interact with light, only via gravity with other matter. Today however, the nature of dark matter remains undetected, and thus remains one of the most profound riddles for astronomy and physics.

The existence of black holes was only theorised until the discovery of X-rays from the Cygnus X-1 source in 1964. These mysterious and massive objects are so dense that even light cannot escape their gravity. In 2002, two international teams led by Reinhard Genzel and Andrea Ghez reported the observation of the motion of S2, a star orbiting the centre of our Milky Way and Sagittarius A*, a powerful source of radio waves lurking in the area. This star, the first to be observed completing a full orbit around the Galactic Centre, proved that our
galaxy also has a central supermassive black hole (which we now believe to be present at the centre of most galaxies).

D08.3.1._Astronomy on Earth
ASTRONOMY IN EVERYDAY LIFE
Decades of technological spin-offs and cross-talk between astronomy and industry led to the development of personal computers, communication satellites, mobile phones, WiFi, Global Positioning Systems (GPS), solar panels and Magnetic Resonance Imaging (MRI) scanners. Increases in computing and telecommunications towards the end of the 20th century meant that ordinary computers could handle calculations that a few decades earlier required some of the world's largest supercomputers. Equally significant was the launch of the Internet. This enabled astronomy to become one of the most open among scientific disciplines, with the global community of researchers sharing data, results and practices, and astronomy enthusiasts contributing via a variety of widely distributed citizen-science projects, ranging from the classic 1990s SETI@home to the more recent Galaxy Zoo and Planet Hunters.

PALE BLUE DOT
What does Earth look like from afar? To answer this question, scientists in 1990 decided to use the cameras of Voyager 1 to capture a series of images of the Solar System before being turned off. This “Family Portrait” of our cosmic ‘neck of the woods’ consists of a total of 60 frames, combined in a memorable mosaic of the Solar System, and is shot from a distance of more than 6 billion kilometres from Earth. Prompted by a suggestion from Carl Sagan, this distant snapshot of Earth became known as the iconic “Pale Blue Dot”, by revealing our planet as a mere speck of light against the vast darkness of space.
