The International Space Station (ISS) regularly hosts spacecraft from various space agencies, docking for crew rotations and resupply missions. These spacecraft include those from NASA (such as the Crew Dragon from SpaceX), Roscosmos (Soyuz), European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), and others with agreements to visit the ISS. If you believe you […]

To calculate how long a modern probe would take to travel 166.3 astronomical units (AU), we need to consider the advancements in propulsion technology since Voyager 1’s launch. Voyager 1 achieved a speed of about 17 kilometers per second relative to the Sun. Technologies that could improve travel times include ion propulsion and solar sails. […]

Opportunity, the Mars rover, succumbed to a planet-wide dust storm in 2018 that blocked sunlight from reaching its solar panels, causing it to lose power and establish communication. The rover operated long past its original 90-sol (Martian day) mission, ultimately spending nearly 15 years on the Martian surface. Theoretically, if Opportunity’s solar panels were cleaned […]

Alpine National Park, with its elevated terrain and remote nature, offers several prime locations for stargazing, away from the light pollution of urban areas. Here are some top spots to consider: Mount Hotham: This is one of the most accessible high-altitude spots in the park. On a clear night, the sky seems to unfold endlessly, […]

Observing an asteroid from Earth can be an exciting experience, but there are a few considerations to bear in mind if you believe you’ve spotted one. Firstly, asteroids are minor planets or rocky bodies that orbit the Sun, typically appearing as small, distant, and sometimes faint objects, often requiring a telescope for clear observation. If […]

To comprehend the relative scales in the universe, it is useful to consider entities and structures that exist across this extensive range. The known universe spans about 93 billion light-years in diameter, which is approximately \(8.8 \times 10^{26}\) meters. Conversely, the electron, a subatomic particle, is incredibly small, with an effective “size” often considered to […]

In ancient Greek and Roman culture, celestial bodies such as the visible planets held significant astrological and mythological importance. The Greeks and Romans did not generally believe that the planets were the actual deities themselves, but rather that they were closely associated with these gods and represented their influence and presence in the cosmos. For […]

The nature of the universe is a profound and complex question that has intrigued scientists and philosophers for centuries. Whether the universe is truly infinite or just exceedingly large is still a topic of considerable debate and research in cosmology. One possibility is that the universe is finite but unbounded, similar to the surface of […]

While the concept of a moon made of glass is intriguing and presents a captivating image, there are significant scientific reasons why it is unlikely for a natural celestial body like a moon to be composed mainly of glass. Glass, in general, is formed from the rapid cooling of molten materials such as silica, often […]
