Geology involves how our world is formed, from beaches to volcanoes. Mountain ranges, rivers, and other geological structures tell a rich tale about Earth’s history. A new Wondrium series explains day-to-day geology. […]
Three well-known volcano types appear around the world. They are shield volcanoes, cinder cones, and composite volcanoes—which are also called stratovolcanoes. This week on Wondrium Shorts, learn to “lava” all three. […]
The Event Horizon Telescope constitutes eight radio observatories scattered all around the globe. Collecting the data, waiting for good weather, and storing, collating, and computing the data were some of the challenges that were successfully tackled by the astronomers. […]
Observing changing x-rays being emitted from Cygnus X-1, a blue star, helped astronomers observe and conclude the existence of black holes. […]
Jocelyn Bell observed pulses of radio data. Their regularity led her to observe it more closely and discover the neutron star. What made it detectable were the flashes of radio pulses it emitted. […]
A neutron star is formed at t he very center of a supernova. Owing to the Pauli exclusion principle of quantum physics, neutrons start exerting an outward pressure, stopping the gravitational collapse of the neutron star’s interior. […]
The existence of water on our planet is due to one unique ability of oxygen and nitrogen. This ability also allows to form the DNA of living organisms. […]
In addition to being crucial for the body and biochemical reactions, nitrogen is used to strengthen the soil and produce high-quality agricultural products. […]
Despite differences in their chemical reactions, oxygen and nitrogen share quite a few similarities. These elements balance the chemical reactivity in the earth’s atmosphere. […]
Within the electromagnetic spectrum, shorter wavelengths of UV, X-rays, and gamma rays are harder to study. This is because shorter wavelengths find it hard to penetrate our atmosphere. Thus, building a telescope to study them from afar and storing them is the challenge only ultraviolet astronomy can take on. […]
