Venus is one of the most inhospitable places in the Solar System, with temperatures hot enough [...]
Many different kinds of exoplanets have been found by astronomers, from giant “hot Jupiters” and “super Earths” to smaller rocky worlds like Earth or Mars. Now, another type has been discovered, an “ice giant” similar to Uranus or Neptune in our [...]
Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data [...]
The universe is a wild and weird place, and two recent findings from orbiting space telescopes illustrate just how bewildering it can be: a monster-sized black hole in one of the tiniest galaxies known and a huge exoplanet that is [...]
Saturn’s largest moon, Titan, is a very alien yet eerily Earth-like world, with rain, rivers, lakes, and seas; seen from above, the landscape has a familiar look to it. But [...]
Solar systems, including ours, are thought to begin as massive clouds of dust and gas surrounding young stars; over billions of years, planets form from repeated impacts of [...]
Is or was there life on Mars? That is one of the biggest and most hotly debated questions in planetary science. The manner in which the evidence has been searched for is also a topic of much discussion. The Viking landers in the 1970s were the [...]
The origin of Saturn’s rings has been one of the most interesting puzzles in planetary science, and now new data from the Cassini spacecraft is helping to fill in the pieces, showing [...]
Saturn’s moon Enceladus is already known as one of the most intriguing places in our solar system, and now new findings from the Cassini spacecraft have been published, which will only add to our fascination with this little world.
The Chandra X-Ray Observatory, NASA’s space telescope which observes the universe using X-rays, has now completed its 15th year of operations, and astronomers are celebrating the anniversary with a series of special images from the orbiting observatory.
