Why We Haven’t Been Invaded by Aliens

As we learned in class, the Drake equation can estimate that the existence of life should exist. The universe is huge, its been in existence for a very long time, and there is no foreseen limit to what can exist, especially life off Earth. Fermi’s paradox is super cool, creepy, exciting and puzzling all at … Continue reading Why We Haven’t Been Invaded by Aliens Continue reading

A little over a month ago, astronomers in Western Australia detected the signals of stars that formed within the earliest epoch of the Universe. This discovery marks the detection of the oldest signals ever to be received, and with it, evidence for the presence of dark matter at a time when the lights of the … Continue reading Primordial Stars and Dark Matter Continue reading

Why Galileo Mattered

When Galileo began using his invention, the telescope, for observation of the cosmos, he was very quickly able to make three discoveries. The most revolutionary of his discoveries were that the surface of the moon was rough and uneven and satellite objects he later identified to be moons orbited Jupiter. These discoveries were fundamental in challenging … Continue reading Why Galileo Mattered Continue reading

“You Heard About Pluto? It’s Messed Up Right?”

When I was a kid we had 9 planets. That 9th planet was Pluto, which was (unfortunately for my generation) demoted to just a dwarf planet in 2006 (NASA: Pluto in Depth). As outraged as I was as a child that Pluto got demoted, the truth is, besides knowing it was the 9th planet, I … Continue reading “You Heard About Pluto? It’s Messed Up Right?” Continue reading

Extrasolar Planets and the Search for Life

Kepler 22-b Extrasolar planets are planets that orbit a star other than our own. Being in another star system, these worlds are very hard to observe since they are so far away and the light they produce pales in comparison to that of the stars they orbit. Because of this, although their existence had already … Continue reading Extrasolar Planets and the Search for Life Continue reading

Io

The Voyager program was first to photograph Io, when it deployed its two high-resolution imaging probes (Voyager I and Voyager 2) on September 5 and August 20, 1977 to investigate the Galilean moon.  Io, one of Jupiter’s four Galilean moon, is a fascinating celestial object.  In fact, Io is the most volcanically active world in our Solar System.  Io’s surface is … Continue reading Io Continue reading
