What if life existed in every solar system?
The Drake equation investigates the likelihood of intelligent, communicating life existing on other worlds in our galaxy. But what if life could easily exist on other worlds, and there was life in every solar system around us? What could this potentially mean for us? First, we must consider the fact that the closest star to […] Continue reading

The Golden Record: A Message Sent to the Cosmos
In 1977, the Voyager I and Voyager II spacecrafts were launched into space to study the outer solar system. After conducting flybys of the planets in the outer solar systems, the Voyager spacecrafts continued to travel away from Earth, and will eventually travel out of our solar system. With this knowledge, golden records were placed […] Continue reading

‘Oumuamua: An Interstellar Visitor
In 2017, a small, long object between 100 and 1,000 meters in length and between 35 and 167 meters in height and width passed through the inner solar system with a trajectory and speed only possible if it originated from beyond our solar system. This object, now known as ‘Oumuamua, is one of the first […] Continue reading

Enceladus: Alien Life in Our Own Solar System?
Enceladus is an icy moon of Saturn, and is fairly small (or medium-sized, for a moon) with a diameter of about 500 km. For reference, the Moon has a diameter of about 3,475 km. Despite its size, however, Enceladus has been rated as among the most probable sources of life in our own solar system […] Continue reading
Proxima: Our Cosmic Neighbor
The closest star to our solar system is one named Proxima Centauri. Proxima Centauri is a relatively small star, as it is a red dwarf star with about 12.5% the mass of the Sun and only about 0.17% as bright as the Sun. Proxima Centauri resides about 4.25 light years away from Earth, and is […] Continue reading
The Cassini Spacecraft
The story of the Cassini spacecraft is one of scientific discovery and self sacrifice. Cassini was launched in 1997 and spent 20 years in space, focusing on the planet Saturn, its moons, and its rings, before the spacecraft’s intentional demise in 2017. Through Cassini, we were able to land a probe on Titan, Saturn’s largest […] Continue reading

The James Webb Space Telescope
As you may have heard in the news recently, the James Webb Space Telescope (or JWST) was launched into space on December 25, 2021. The JWST is meant to be the successor to the Hubble Telescope, as it detects light further into the infrared spectrum than the Hubble telescope, and so can see stars that […] Continue reading
Johannes Kepler in Historical Context
Johannes Kepler (December 27, 1571 – November 15, 1630) revolutionized astronomy and improved upon the works of previous astronomers (including Copernicus and Tycho) in multiple ways. Kepler was able to develop a mathematical model of the universe that was heliocentric and was both more accurate and simpler than that of Ptolemy, whose geocentric model with […] Continue reading

Totality
On August 21, 2017, my family and I drove from Atlanta, Georgia to Clemson University in South Carolina to witness the solar eclipse in totality. Atlanta reached 97% totality, but Clemson reached complete totality: At about 2:37 PM, the moon completely covered the sun, positioning itself perfectly between earth and the sun and casting a […] Continue reading
Starting Up
By me This picture is from when I visited my sister abroad over Thanksgiving Break. I am Quint Gfroerer, I’m from Atlanta, GA, and I am a junior majoring in neuroscience and minoring in astronomy. Continue reading
