The bright spots, now known to be composed of sodium carbonate, are one of the biggest clues as to current activity, and the new images and data will help to finally answer the question of how they got there.

Also to know is, why does Ceres have bright spots?

Reflectivity studies from September 2015 suggest that the spots are probably salts rather than ice, implying that Ceres's interior is somehow delivering fresh salt to the surface.

What is the white spot on Ceres?

NASA's Ceres-orbiting Dawn spacecraft has captured jaw-dropping new photos of several of the bright-white features, formally known as faculae, that lie at the bottom of the dwarf planet's 57-mile-wide (92 kilometers) Occator Crater.

What are the lights on Ceres?

Occator's floor hosts odd bright deposits, which Dawn discovered during its approach to Ceres in early 2015. Subsequent observations by the probe revealed that the bright stuff, which also occurs at several other locations around Ceres, consists of sodium carbonate.

What is the bright spot on the moon?

Tycho Crater on the Moon (Labeled) Tycho Crater is one of the most prominent craters on the Moon. It appears as a bright spot in the southern highlands with rays of bright material that stretch across much of the nearside.

Why does the moon have spots?

These dark spots were called as craters,Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies.

What did Dawn discover about Ceres?

Dawn measured Ceres' surface composition and found a chemical (ammonia), which requires the colder temperatures of the outer solar system -- beyond the orbit of Jupiter -- to condense. Ceres may have formed there and then drifted closer to the Sun.

What is Ceres made out of?

Ceres probably has a solid core and a mantle made of water ice. In fact, Ceres could be composed of as much as 25 percent water. If that is correct, Ceres has more water than Earth does. Ceres' crust is rocky and dusty with large salt deposits.

Why is Ceres a dwarf planet?

And when Dawn arrived in 2015, Ceres became the first dwarf planet to receive a visit from a spacecraft. Called an asteroid for many years, Ceres is so much bigger and so different from its rocky neighbors that scientists classified it as a dwarf planet in 2006.

What is the blue light on Ceres?

Early in the orbital phase of the Dawn mission, the high albedo of these spots was speculated to be due to some kind of outgassing, and subsequent closer images helped scientists determine that it is a material with a high level of reflection, and suggested ice and salt as possibilities.
