Look Back at It
The surfaces of the terrestrial planets tell us a lot about their histories. The geological surface features of the planets give insight into the geological processes that have occurred in the planets’ pasts. There are four main processes that have lasting geological impacts on the terrestrial planets in our solar system. The processes are impact … Continue reading “Look Back at It”

Planet 9
It was a sad day when the powers that be decided that Pluto was no longer fit to be called a planet. However, this January, in a shocking turn of events, scientists at Caltech may have discovered (or somewhat indirectly presume) the existence of a real ninth planet, an ice giant by the incredibly original […]

The Stardust Mission
Missions that deliberately bring back extraterrestrial material to Earth are rare. The NASA Stardust, a probe that launched in 1999, sought to collect dust samples from the comet Wild 2’s tail. Prior to the mission, experts believed that the dust in comets’ tails would be pre-solar particles. Instead, what they found from the particles retrieved […]

Pillars of Creation
The above photo is a picture captured by NASA’s Hubble Space Telescope of what is now known as the “Pillars of Creation.” Located in the Eagle Nebula, which is around 6,500 – 7,000 light years away from Earth, the structures are named as such because of their pillar-like shape, as well as because the gas […]

A Natural Lightshow
When I think about light shows, I think about Disney World. Every night in the Magic Kingdom that have a “lightshow spectacular” full of elaborate parade floats decked out in incredible light schemes set to music. The show is pretty cool, but there’s one even cooler that our Earth puts on every night all on […]

Gravity has waves?
Admittedly, I am late on the whole gravitational waves discovery, however I think that this video above is probably the best explanation as to what gravitational waves are and how scientists actually managed to find evidence for the waves. The way that scientists actually discovered the waves fascinated me most in all the of news […]

The Voyager Mission
Launched in 1977, the Voyager 1&2 continue to explore deeper into space than any instrument ever before. Using geometries and precise calculations, the space probes were able to perform flybys of Jupiter, Saturn, Titan, Uranus, and Neptune. Upon completion of the primary objectives, they were assigned the new mission of exploring further and further away from […]

Are We Alone in the Universe?
And why does that question seem to be so hard to answer? Our universe is vast. There’s no doubt about that. And statistically, we should be able to find life in some way, shape, or form somewhere in the seemingly endless cosmos. For every grain of sand on Earth, there are ten thousand stars in … Continue reading Are We Alone in the Universe? →

The Pock-Marked Sun God
Sunspots are areas on the Sun that appear darker compared to their surroundings because they are cooler than the areas around them. This does not mean that the spots are actually cold, but relative to the 5800K temperature of the rest of the Sun, sunspots are much cooler at 4000K. Magnetic fields prevent the hotter …
