On February 11, 2016, the LIGO Scientific Collaboration announced that they had made the first observation of gravitational waves.

They were first predicted by Albert Einstein in 1916 on the basis of his theory of general relativity. Accelerating motion of masses like stars or black holes produces gravitational waves in the fabric of space-time, "distorting" and "bending" it.

However, no matter how insignificant and small it is, even a flying mosquito continuously produces ripples in the spacetime throughout the entire cosmos, in the form of "gravitational radiation"

This infographic showcases the most important information about what gravitational waves really are, and how we can observe them.

This visualisation shows more than 500 exoplanets discovered before October 2015 (about 1/4 of all exoplanets yet discovered), arranged according to their temperature and density, showing the incredible variety of the extraterrestrial worlds.

Various known classes of exoplanets are shown on the graphic, such as super-earths, hot jupiters, hot neptunes, water worlds, gas dwarfs or superdense diamond planets. All visualisations are based on the estimated radius and temperature of the planet, however other factors, such as density, age or stellar metallicity were also taken into consideration.

These visualisations were meant to be as accurate as possible, however the true nature of the portrayed exoplanets might turn out to be radically different.

Collection of 6 detailed charts showing the sequence of the tallest buildings in every continent (Europe, Asia, North America, South America, Africa, Oceania) throughout the ancient and modern history. The chart shows the name and to-scale silhouette of each building, the years during which it was the continent’s tallest, and year of construction(unless it’s the same as the year when it became the world’s tallest). For comparison, numerous structures that are not actual buildings(pyramids, observation towers, monuments) were featured on the chart for their cultural significance, but were not counted as the “tallest building”. Red-tinted buildings on the charts have also held the record for the world’s tallest building at least once during their existence. All height figures represent pinnacle height, not roof height.

Though on the short timescale, stars appear to mantain nearly fixed positions in relation to each other, long-term observations show that all stars indeed move and all constellations gradually change over time.

This chart shows how the various constellations and asterisms on the night sky(namely the Big Dipper, Orion, Crux, Leo, Cassiopea and Lyra) changed throughout the human history and how will they look to an earth-based observer in the distant future, due to the proper motion of stars in our galaxy.

All data used to make this chart was gathered from the Hipparcos Catalogue, which was published in 1997 by the European Space Agency. It was a result of the 4-year long mission of the Hipparcos satellite. Visualization was achieved using the special astronomical software HippLiner.

This visualization shows how the sunset could look like to a human observer if our Sun was replaced by some of the other stars in our galaxy with different sizes and magnitudes, namely Barnard’s Star, Gliese 581, Tau Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and Aldebaran.
