The Science of Black Holes: Hawking Radiation Explained

Supermassive_black_hole

Black holes are one of the most intriguing features of our universe. They were originally predicted by the equations in Einstein’s theory of general relativity in 1915. Many scientists doubted the existence of black holes throughout the 20th century, assuming they were merely a mathematical glitch in an incomplete theory. However, modern physicists almost unanimously accept that black holes exist. In fact, current theories in cosmology posit that supermassive black holes are at the center of almost every major galaxy.

Anomalies in the Standard Model of Cosmology

Dark Energy Research

Researchers, including physicists from Heidelberg University, have gained new insights into dark energy and the theory of gravitation by analyzing data from the Planck satellite mission of the European Space Agency (ESA). Their results demonstrate that the standard model of cosmology remains an excellent description of the universe. Yet when the Planck data is combined with other astronomical observations, several deviations emerge. Read More →

ESA’s Gaia Mission Aim Highs

Yesterday I posted about the important work being conducted on theĀ LSST project. Today I wanted to cover another amazing project – ESA’s Gaia mission.

While many space borne observation platforms have provided excellent images to scientists, these have mostly been in two dimensions thus far. Gaia is a very ambitious mission by the European Space Agency to make a three dimensional map of the Milky Way. While GAIA originally stood for Global Astrometric Interferometer for Astrophysics, it seems that the acronym has been dropped in favor of the shorter name. Read More →
