As some of you may have surmised, I have a passing interest in conspiracy theories. As a philosopher, I am fascinated by some of the fantastical contrivances that slip out of the mouths of people like Alex Jones and David Icke. My fascination stems from genuine curiosity, with specific regard to how anyone could rationalize the world so poorly.
Betelgeuse will explode someday. It lies some 430 light-years from Earth. Yet it’s already one of the brightest stars in Earth’s sky. The reason is that Betelgeuse is a supergiant star. It is intrinsically very brilliant.
A generation ago, the idea of a planet orbiting a distant star was still in the realm of science fiction. But since the discovery of the first exoplanet in 1988, we’ve found hundreds of them, with the discoveries coming at a faster rate over time.
Astronomy is probably the oldest science. Ancient civilizations around the world gazed up at the sky and the stars, but it wasn’t until the scientific enlightenment of the 17th century that astronomers were able to get a handle on how things actually worked up there. These new discoveries would eventually lead to the rich, fascinating picture of the universe we have today. Here are a few significant milestones that had to be reached along the way.
The ultimate fate of the universe is a topic in physical cosmology. Most of the cosmologists says that the ultimate fate of the universe is dependent on the shape of the universe and what role dark energy will play as …
The past two years have been a little confusing for NASA’s Voyager 1 space probe, as its status as an interstellar traveller has been considered, debated, officially confirmed and then debated some more. However, new data looks to confirm that the intrepid spacecraft is actually in interstellar space, and the mission scientists have our Sun to thank for it.
Mercury, Venus, Earth and Mars are known as the rocky planets, in contrast the Solar System’s gas giants-Jupiter, Saturn, Uranus and Neptune, writes Time. Yet Mercury doesn’t quite fit with the other rocky worlds, Erik Asphaug, a planetary scientist at Arizona State University, said in a statement.
The real face of life on alien worlds is far stranger than fiction. There’s an exotic zoo of planets out there many of them aren’t anything like the kind of planets we find in our own solar system. Space telescopes have spotted thousands of potential planets for extraterrestrials to call home. Using this data, we are zooming in to determine what the alien inhabitants might look like.
Stars such as the sun usually form clusters along with other stars. Many of them are spread out, allowing the stars to drift apart, although others are more intense with gravity keeping the stars closer together. Today, the sun stands alone which makes astronomers wonder that our star and its solar system had either been evicted from its original cluster or moved away from its sibling stars around 4.5 billion years ago.
