Mysterious bright spots on Ceres: what do latest NASA photos reveal?

NASA photos released today show the glowing spots in unprecedented detail.

A cluster of mysterious bright spots on dwarf planet Ceres can be seen in this image, taken by NASA's Dawn spacecraft from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was taken on June 9, 2015.

Scientists on the Dawn mission have just received the clearest photos of the planet Ceres to date. The mission has been investigating two protoplanets in our solar system, Vesta and Ceres, in order to understand the conditions and processes of ancient history, according to the mission’s website. In May, photos of a mysterious bright spot on the surface of Ceres revealed a cluster of high-albedo areas of unknown origin.

The Dawn mission launched in 2007 and explored Vesta beginning in 2011 for over a year; now the mission is orbiting the dwarf planet Ceres. The two protoplanets are between Jupiter and Mars in the asteroid belt, and are the largest objects between the two planets.

The spacecraft, designed and built by Orbital ATK, Inc., has been able to get closer to the planet in the past couple of months, transmitting clearer photos back to Earth each time and offering sharper images of the mysterious bright spots on Ceres. Numerous theories about the bright spots have arisen since the beginning of the year, including that they may have volcanic origins or could be sheets of ice. The two protoplanets are known to be cold, and some suspect that cryovolcanoes, ejecting water, methane, and ammonia onto the surface, could be responsible.

Dawn’s principal investigator, Christopher Russell, of the University of California, Los Angeles, said in a statement last month, “Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice.” The case is not yet closed, however, as scientists continue to consider other possibilities.

Dawn's futuristic ion propulsion system will make it the first spacecraft to orbit two bodies in the solar system, but the technology doesn't allow for speed, relative to rocket-propelled spacecraft. Some maneuvers will take weeks to execute. In less than a week, the spacecraft will begin to spiral down towards Ceres in order to get closer to these bright spots and hopefully to aid in answering questions about their nature and origin.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
