Explore Vesta with Vesta Trek
Today, NASA released Vesta Trek, a free web-based application that provides a detailed visualization of Vesta, one of the largest asteroids in the Solar System. This was made possible by NASA’s Dawn spacecraft, which studied Vesta from July 2011 to September 2012. This application includes interactive maps, the ability to print Vesta in a 3-D printer, […]

The Rosetta Mission
Over spring break, I came downstairs for dinner and my dad just so happened to be watching a PBS documentary on the ESA (European Space Agency)’s recent Rosetta mission. The documentary explains the behind the scenes work that went into developing the mission, giving insight into the building of the orbiter, the unique technological features,… Continue reading The Rosetta Mission

The Continual Search for Planets
The discovery of new life-harboring planets has been a hot topic in the last century, but there has always been a limitation: we couldn’t see other planets. However, observational technologies and techniques have progressed to the point where we may be able to find more Earth-like planets within a few short years. The main problems […]

The Early Telescopes
The earliest working telescopes was made around 1608 with many who claimed its discovery. The design was simple; a convex objective lens and a concave eyepiece allowed the user to see further. In 1655, astronomers had build more powerful telescopes using a design by Kepler. This design used a convex objective lens and a convex […]

Weight is just a number!
picture from storejpg.com Weight IS just a number-it’s simply the product of the mass of an object and the force put on that object due to gravity! Since the number is dependent on gravity, it’s totally logical that, since the force of gravity from the Sun is different in different locations in the Solar system […]

What Comes After Hubble?
The Hubble Space Telescope, in use for about 25 years, will soon have to be retired in the next 5-10 years. Plans for a successor telescope eventually materialized into the James Webb Space Telescope, pictured below as a full scale model in Austin, TX. As big as a tennis court and as tall as a […]

The first navigational tool
Image from kaloujm.com People have been using the sky as their source of navigation for years, and one of the first tools made for the purpose of aiding in navigation (that wasn’t a body part!) was the kamal. The exact date is unsure, but it’s estimated that this tool came into use around the fifth […]

Hubble Telescope
In April 1990 NASA launched the Hubble Telescope in an orbit around Earth. The telescope has been orbiting Earth for almost 25 years and is monumental in its contribution to science. The information gathered by the telescope has helped astronomers to narrow down the age of the universe down to a few hundred million years, […]
