WFIRST: The Newest Vanguard of the Mission to Understand Dark Energy

At some point this decade, a new space observatory will be launched into orbit; one unlike any that we have seen before with extraordinary equipment and capabilities. WFIRST, the Wide-Field InfraRed Survey Telescope, could potentially revolutionize what astronomers know about our universe and how it behaves by focusing on three major categories: dark energy, exoplanetContinue reading “WFIRST: The Newest Vanguard of the Mission to Understand Dark Energy” Continue reading

Introduction to various spacecraft propulsion methods

Space propulsion is different from regular propulsion methods that deal with situations on the ground or in the air. It’s also different from launch propulsion which space propulsion methods exclusively deal with propulsion systems used in vacuum of space. Before introducing different propulsion methods, there are couple of concepts that are really important related to … Continue reading Introduction to various spacecraft propulsion methods Continue reading

The Quest to Inhabit Mars

As a species, we need multiple paths to survival. One of which is living in space. With this in mind, companies like SpaceX have plans to colonize Mars. But why Mars? It is the next most habitable planet after Earth. It contains water, temperatures that are not too hot nor too cold, enough sunlight, ability … Continue reading The Quest to Inhabit Mars Continue reading

Electric Propulsion

A propulsion method I was unaware of is electric propulsion (EP). An EP system consists of thruster components, propellant components, power components, and an optional pointing mechanism. Essentially, electric and magnetic fields react to charged particles in the rocket’s exhaust which accelerates charged particles that make up propellant. This requires less energy than chemical rockets … Continue reading Electric Propulsion Continue reading

Hello Powehi

In the center of the galaxy M87, stars seem to orbit an invisible object. By observing the path of the stars, scientists concluded that there is a supermassive black hole that is dense enough to cause these motions. Although the black hole itself is invisible, we can still observe the ring of light bended by … Continue reading Hello Powehi Continue reading

Future Exoplanet Research

The future of exoplanet research means not just the discovery of more exoplanets, but characterizing them. To do so, the European Space Agency (ESA) is launching the Characterizing Exoplanet Satellite (CHEOPS), the PLAnetary Transits and Oscillations of stars mission (PLATO), and the Atmospheric Remote-Sensing Infrared Exoplanet Large-survey mission (ARIEL). CHEOPS will observe bright stars with … Continue reading Future Exoplanet Research Continue reading

Understanding Our Sun

On August 12, 2018 the Parker Solar Probe was launched. The mission of this probe is to investigate activity in the Sun’s corona in order to provide us with information that can help us understand more about the star and Earth’s connection to it. Analyzing the data being sent back will allow scientists to potentially … Continue reading Understanding Our Sun Continue reading

Electric Cars and Climate Change

Climate change is the change in global climate patterns due to an increase in fossil fuels. A solution to mitigate these emissions released by fossil fuels is converting automobiles to use only electric energy. However, the electricity used by electric vehicles also generates harmful emissions due to power plants that use fossil fuels to generate … Continue reading Electric Cars and Climate Change Continue reading

The window of universe — Various types of Telescope

The science of astronomy is about the telescopes. Without them, our naked eyes can only see thousands of stars in the night sky away from city lights. We get to see galaxies, stars, nebulas and other celestial objects that are light years away from us through telescopes. Furthermore, as the technology improved over the last … Continue reading The window of universe — Various types of Telescope Continue reading
