OGLE-2016-BLG-1195Lb or The Iceball Planet

(ScienceDaily) Yesterday, NASA’s Jet Propulsion Laboratory (JPL) announced the discover of a new planet orbiting the star much fainter than our sun, but, it is of similar size to earth and a similar distance to earth. In fact, this is actually the smallest planet ever discovered using a technique called microlensing (ScienceDaily). Microlensing utilizes the … Continue reading OGLE-2016-BLG-1195Lb or The Iceball PlanetContinue reading Continue reading

Blog 4: Voyager Mission

(NASA) The voyager mission consists of 2 spacecrafts, Voyager 1 and Voyager 2. The purpose of their mission is to explore the farther reaches of our Solar System. This area is defined by NASA as “beyond the neighborhood of the outer planets to the outer limits of the Sun’s sphere of influence” (NASA). However, both … Continue reading Blog 4: Voyager MissionContinue reading Continue reading

Blog 3: Cosmic Background Radiation

A radiation that is an after-effect of the Big Bang still around today. It was actually discovered accidentally by two Arno Penzias and Robert Wilson in 1965. They noticed a static that appeared to be coming from every direction at the same strength. Later scientists were able to trace out a Black Body curve for … Continue reading Blog 3: Cosmic Background RadiationContinue reading Continue reading

Blog 2: Celestial Navigation

Even though astronomers use scales such as arcseconds and arcminutes to measure certain distances between stars, the main tool of celestial navigation, the sextant, is only able to measure arcminutes. The sextant uses reflection in order to find the angle of celestial objects. Traditionally, the sextant has two mirrors. The horizon mirror is stationary and … Continue reading Blog 2: Celestial NavigationContinue reading Continue reading

Blog 1: The Speed of Light And Refractive Index

Light travels at a velocity incredibly difficult for us to comprehend other then as just a very, very large number. To be exact, light travels at a constant velocity of 299,792,458 m/s within a vacuum. This is not the same for light traveling through other conditions. When light does travel through things other then a … Continue reading Blog 1: The Speed of Light And Refractive IndexContinue reading Continue reading
