PIX4634481: The first galaxies - The first galaxies - Artist's view of the appearance of giant stars at the intersection of hydrogen filaments, which will form the nuclei of the first galaxies. Giant stars form at the intersections of great filaments of primordial hydrogen, forming the nuclei of the first galaxies, Dixon, Don (b.1951) / Bridgeman Images
PIX4645712: Mission New Worlds: The New Worlds mission is a space mission proposal being studied by NASA. Its concept is based on the association of a space telescope with a large occulter (starshade) which places in space a long distance from it (several tens of thousands of kilometres) and designed to block the light of the central star in order to observe its exoplanets. Observations could be made with an existing space telescope, such as the James-Webb Space Telescope (JWST) once launched. A space telescope observes planets orbiting a distant star whose glare has been blocked by a flower-shaped screen the size of a football field. In reality, the starshade would be almost as far from the telescope as the moon is from earth., Dixon, Don (b.1951) / Bridgeman Images
PIX4633495: The Moon barely formed seen from the Earth - Illustration - The Moon barely formed seen from the Earth - Illustration - The Moon would be born from the impact of a big asteroid on Earth. The material ejected during this collision would have combined to form the Earth's satellite. This artist's view shows the Moon seen from Earth with a ring of ejectees in its orbit, Dixon, Don (b.1951) / Bridgeman Images
PIX4630295: The formation of the Solar System - Artist view - Forming solar system - Artist view - Artist view of the gas and dust disc (protoplanetary disc) around the Sun. Little by little rocks will gather, accrete, to form planets. Planetesimals - the seeds of planets crash together in the solar nebula, gradually growing larger, Dixon, Don (b.1951) / Bridgeman Images
PIX4572829: Artist view of a magnetar - Magnetar - Artist view - Artist view of an eruption of X-rays and gamma from a magnetar, a neutron star endowed with a powerful magnetic field. Artist's concept of a burst of X - rays and gamma released by a magnetar, a neutron star with an extremely powerful magnetic field, Dixon, Don (b.1951) / Bridgeman Images
