A New Way to Travel Through Space

Posted on May 1, 2018 by jonsastroblog

Solar sails are a new and incredibly interesting propulsion system that is currently undergoing various testing around the globe. Instead of being powered by rockets, solar sails allow spacecrafts to be powered by the sun itself. Just as a sailboat is pushed along by the winds on the ocean, solar sails are pushed along by … Continue reading A New Way to Travel Through Space → Continue reading →

Primordial Stars and Dark Matter

Posted on April 10, 2018 by stellarastronomy1995

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 →

James Webb Space Telescope

Posted on April 8, 2018 by yadavdhruv

In 1995, one of the most famous photos in astronomy was taken by the Hubble Space Telescope. Dr. Robert Williams instructed his team to point the lens at nothing in particular in the sky – only 0.9 arc seconds of the night sky. Over 10 consecutive days, Hubble took over 342 exposures and combined them … Continue reading James Webb Space Telescope → Continue reading →

August 20, 1977. The flyby-type probe Voyager 2 was launched from Earth, destined to explore our Solar System and beyond. Passing by Jupiter, Saturn, Uranus, and Neptune, Voyager 2 carried with it instruments to relay close-up images of these Jovian planets, and a message from Earth to be read and listened to by those who … Continue reading Voyager 2 → Continue reading →

Blog 4: The Sirens of Titan

Posted on March 14, 2018 by battismm

One of my favorite novels is The Sirens of Titan by Kurt Vonnegut. As the title suggests a portion of the novel takes place on Saturn’s moon Titan, though this fiction is more concerned with the philosophical and not the realistic astronomical. I highly recommend it to fans of science fiction. Discovered in 1655, Titan is Saturn’s … Continue reading Blog 4: The Sirens of Titan Continue reading →

1 Shift, 2 Shift, Redshift, Blueshift

Posted on February 14, 2018 by jonahastroblog

Space is vast. In fact, vast enough to contains many million, billions, and trillions of galaxies and other celestial objects. So the ultimate question is, how do scientists keep track of all of the celestial bodies? How do we know that the Andromeda galaxy is coming toward us if we can’t tell if it is… Continue Reading → Continue reading →

Radio Telescopes

Posted on February 12, 2018 by mattbarnhartastro2110

When someone says “telescope,” you probably think of a long magnifying tube ranging from pocket sized to massive that you can look in an eyepiece of to see things at great distances, such as stars and galaxies in regards to astronomy. Another type of telescope you may not think of is the radio telescope. The … Continue reading Radio Telescopes → Continue reading →
