Astronomers have discovered an enormously massive galaxy, NGC 1600, 209 light years away. NGC 1600 is an elliptical galaxy that is 17,000,000,000 billion solar masses. There are many massive black holes in the Universe (Source). In fact, there is a black hole at the center of every galaxy. It is thought that perhaps black holes […] Continue reading → Continue reading
An article by Christopher Crockett in ScienceNews came out 5 days ago that stated the amount of power output by the merging of two black holes. This was the same event detected by the Laser Interferometer Gravitational-Wave Observatory, the first detection of observational gravitational waves. The power of merger was apparently 3.6 x 10^49 watts! […] Continue reading → Continue reading
We know that there are many different types of light in the Universe. Each type gives us unique information about the object we are studying. The above picture from NASA contrasts the same celestial object, the Milky Way, in different wavelengths. Note that the further we deviate on either side (longer or shorter wavelength), the […] Continue reading → Continue reading
One of the beautiful aspects of the universe is that not every celestial object is exactly the same. The majority of stars spend their lives on the “main sequence” in which they have stable volume and continuously undergo hydrogen fusion. Astronomers use a classification system based solely upon the temperature of a star, assigning each […] Continue reading → Continue reading
Tycho Brahe made many important contributions to astronomy in a variety of ways. He made regular observations of the heavens and tabulated that information so that other scientists (like Kepler) could use them. He engineered and calibrated his own instruments. Brahe also theorized–he made his own solar system model that incorporated both Copernicus’ and Ptolemy’s […] Continue reading → Continue reading
It is hard to imagine the actual scale of the universe from a human perspective. Humans have personally witnessed the vastness of space only as far as the Moon and Earth orbit (International Space Station, as one vehicle). Instead, computer stimulations can help us get an idea of exactly how far the universe, as we […] Continue reading → Continue reading
