Over the past couple decades, astronomers have been discovering a seemingly endless variety of exoplanets orbiting other stars. Some are rather similar to planets in our own Solar System, while others are more […]

The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s illustration of the brights spots Occator crater and elsewhere, based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the […]

'Cauliflower' Silica Formations on Mars: Evidence of Ancient Life?

Was there ever life on Mars? That is one of the longest-running and most debated questions in planetary science, and while there have […]

NASA Developing New 'Chemical Laptop' to Search for Evidence of Alien Life

One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on […]

GJ 1132b: Nearest Earth-Sized Exoplanet Discovered So Far May Be a 'Venus Twin'

Astronomers have discovered another Earth-sized exoplanet that is the closest one to our own Solar System found so far, but it might not be a […]

Gemini Planet Imager Finds Its First Exoplanet, a Methane-Rich 'Young Jupiter'

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 […]

When it comes to planetary rings, what do you think of? Saturn is the first obvious thing that comes to mind, with its famous majestic ring system surrounding the gas giant planet. The other gas and […]

Three new exoplanets discovered in star cluster

Three more exoplanets have just been found, adding to a long and rapidly growing list, but their location makes them a bit more unique – they orbit three different stars in a star cluster rather than […]
