The Big Crunch
While the Big Bang has become the quintessential theory for the beginning of the universe, the possible future of the universe is still an open question. While the universe we currently observe is expanding in all directions, who is to say that this expansion will continue indefinitely. And if the expansion of the universe ends, […]

New technologies in mapping space weather
One of the fundamental concepts in the study of astronomy is the dependency of Earth and every other planet in the solar system on the characteristics of the Sun. From emissions of hot gas to violent space wind to bursts of extra energy (via solar flares), the behavior of the Sun, dubbed as space weather, […]

Why is the Moon so Crater-y?
Have you ever wondered why the Moon is full of so many craters? The surface of the Moon is so textured that many of its topographic features are visible from Earth with the naked eye. Most people would say that all of the crater scars on the Moon’s surface are a result of meteor impacts. […]

Timeline of space exploration
Astronomy is the the oldest of the natural sciences! Back in antiquity, it also contained Astrology, but they were separated to two different sciences during the Renaissance period. Also, Astronomy contained Astrophysics, Cosmology, and other “pieces” which became independent sciences in the 20th century. Astronomy started many-many years ago in ancient countries such as Egypt, […]

Blog #3: PSR J1719-1438 b
PSR J1719-1438 b is a really cool planet. It’s small and massive, and oh yeah, it’s made of diamonds. PSR J1719-1438 b orbits around star PSR J1719-1438, which is a neutron star and a pulsar. Basically, because the star’s magnetic field is so great, it sends off waves of radiation. The relationship between the star … Continue reading Blog #3: PSR J1719-1438 b

Blog #3
The Earth is around 4.5 billion years old. The first half of the Earth’s existence (prior to the Great Oxidation Event which essentially introduced free oxygen (dioxygen) into the Earth’s atmosphere) was characterized by the presence of certain types of bacteria, although evidence of this existence on our planet is limited. However, last year, researchers … Continue reading Blog #3

Solar Probe Plus
In 1976, NASA’s Helios 2 spacecraft set the current distance record by orbiting the Sun with a closest approach of 43.4 million kilometers. Even though this is barely inside the orbit of Mercury, the intense heat close to the Sun has previously prevented any closer observation. The Goddard Space flight Center “Living with a Star … Continue reading Solar Probe Plus →
