NASA Finds Mysterious Bright Spot on Dwarf Planet Ceres: What Is It?

A mysterious white spot can be seen in the newest images from NASA’s Dawn space telescope, which is rapidly approaching the dwarf planet.

A strange, flickering white blotch found on the dwarf planet Ceres by a NASA spacecraft has scientists scratching their heads.

The white spot on Ceres in

a series of new photos taken on Jan. 13 by NASA’s Dawn spacecraft,

which is rapidly approaching the round dwarf planet in the asteroid belt

between the orbits of Mars and Jupiter. But when the initial photo

release on Monday (Jan. 19), the Dawn scientists gave no indication of

what the white dot might be.

“Yes, we can confirm that it is something on Ceres that reflects more

sunlight, but what that is remains a mystery,” Marc Rayman, mission director and chief engineer for the Dawn mission, told Space.com in an email.

The new images show areas of light and dark on the face of Ceres,

which indicate surface features like craters. But at the moment, none

of the specific features can be resolved, including the white spot.

“We do not know what the white spot is, but it’s certainly intriguing,”

Rayman said. “In fact, it makes you want to send a spacecraft there to

find out, and of course that is exactly what we are doing! So as Dawn

brings Ceres into sharper focus, we will be able to see with exquisite

detail what [the white spot] is.” 

Ceres is a unique object in our solar system. It is the largest object in the asteroid belt and

is classified as an asteroid. It is simultaneously classified as a

dwarf planet, and at 590 miles across (950 kilometers, or about the size

of Texas), Ceres is the smallest known dwarf planet in the solar

system.
