With its dark, heavily cratered surface interrupted by tantalizing bright spots, Ceres may not remind you of our home planet Earth at first glance. The dwarf planet, which orbits the Sun in the vast asteroid belt between Mars and Jupiter, is also far smaller than Earth (in both mass and diameter). With its frigid temperature and lack of atmosphere, we’re pretty sure Ceres can’t support life as we know it.
But these two bodies, Ceres and Earth, formed from similar materials in our solar system. And, after combing through thousands of images from NASA’s Dawn spacecraft, which has been orbiting Ceres since 2015, scientists have spotted many features on Ceres that look like formations they’ve seen on Earth.
By looking at similar features on different bodies — what scientists call “analogs” — we can learn more about the origins and evolution of these bodies over time. Check out these prominent features of Ceres, and see if you recognize any of their earthly cousins!

Dark energy survey offers new view of dark matter halos, physicists report
Dark matter, a mysterious form of matter that makes up about 80 percent of the mass of the universe, has evaded detection for decades. Although it doesn’t interact with light, scientists believe it’s there because of its influence on galaxies and galaxy clusters. […]Read More
A better way to weigh millions of solitary stars
Astronomers have come up with a new and improved method for measuring the masses of millions of solitary stars, especially those with planetary systems. […]Read More
Discovery of new planet reveals distant solar system to rival our own
The discovery of an eighth planet circling the distant star Kepler-90 by University of Texas at Austin astronomer Andrew Vanderburg and Google’s Christopher Shallue overturns our solar system’s status as having the highest number of known planets. We’re now in a tie. […]Read More
Dawn of a galactic collision
A riot of colour and light dances through this peculiarly shaped galaxy, NGC 5256. Its smoke-like plumes are flung out in all directions and the bright core illuminates the chaotic regions of gas and dust swirling through the galaxy’s centre. Its odd structure is due to the fact that this is not one galaxy, but two—in the process of a galactic collision. […]Read More

Mars mission sheds light on habitability of distant planets
How long might a rocky, Mars-like planet be habitable if it were orbiting a red dwarf star? It’s a complex question but one that NASA’s Mars Atmosphere and Volatile Evolution mission can help answer. […]Read More
Spanning disciplines in the search for life beyond Earth
The search for life beyond Earth is riding a surge of creativity and innovation. Following a gold rush of exoplanet discovery over the past two decades, it is time to tackle the next step: determining which of the known exoplanets are proper candidates for life. […]Read More
