Binary Star Collision
Binary stars were stars orbiting each other, and they might eventually collide due to the stellar mass loss or gravitational radiation which caused the decay of orbits. Stellar collisions could be amazing and rare, which happened once every 10000 years in our globular clusters. It was very likely, from scientists’ approximation, that a binary star […] Continue reading

History of Telescopes
While there were some objects artificially resembling telescopes in the ancient world, and even some used for sighting, the first modern telescope would have been the work of a Dutch glasses-maker named Hans Lippershey, in 1608. This is merely the first documented one though, as he was the person to file a patent, and theContinue reading “History of Telescopes” Continue reading

First Super-Earth Exoplanet with Atmosphere Discovered
Earlier this month, scientists discovered the existence of an atmosphere on an exoplanet much like Earth, making this the first Earth-like exoplanet with atmosphere to have been detected aside from earth itself. The planet is named GJ 1132b, located in the constellation Vela as a planet of the low-mass star GJ 1132. The planet is […]

Blog #3 James Webb Space Telescope
The flagship of the next generation telescopes launches in October 2018. The James Webb Space Telescope is an infrared telescope with its focus on the very first light from the Big Bang. With its 6.5 meter primary mirror and various cameras and spectrometers, the JWST will study the boundaries of the observable universe as well […]

Dark Matter
In honor of the pre-release of a song I wrote called “Dark Matter,” I wanted to do a post on the subject that inspired my song. The above picture is of the merging galaxy cluster Abell 520. This galaxy cluster formed from the collision of many massive galaxy clusters. The image shows dark matter, hot …

Blog #2 Observation
Much of what has been covered in class so far has been from the perspective of an observer on Earth. We know that light pollution from cities makes it difficult to see starlight with the naked eye. With that in mind, observatories tend to be far away from city limits. Additionally, they tend to be […]
