A new research article provides the answer: Ceres didn't form in the asteroid belt. It formed further out in the solar system and then migrated to its current position. This isn't the first study to reach that conclusion, but it adds weight to the idea.
The article is "Dynamical Origin of the Dwarf Planet Ceres," and it's published in the journal Icarus . The lead author is Rafael Ribeiro de Sousa, a physics professor at Sao Paulo State University in Brazil. Other co-authors come from the same university and France and the U.S.
Earthbound space dust comes from solar system's edge | Astronomy.com
When you notice that faint glow of reflected sunlight in the dark sky just before dawn and after twilight, you’re actually looking at the zodiacal dust cloud.
This dust was long thought to come from collisions in the main asteroid belt as well as among Jupiter-family comets — with little chance of particles reaching Earth from the Kuiper belt, a doughnut-shaped region beyond the orbit of Neptune that contains comets, asteroids and other icy ...
NASA left baffled as Voyager spacecraft sends 'impossible data' from Solar System edge | ...
The agency's engineering team are in the midst of uncovering a new mystery, after scientists observed abnormal data being sent from the probe.
NASA noted that while the spacecraft is receiving and executing commands from Earth successfully, the readouts sent from the probe’s attitude articulation and control system (AACS) do not reflect what is actually happening onboard Voyager 1.
Ice giants and icy moons: The planetary science decadal survey looks beyond Mars to the outer ...
The last time the planetary science community came together to conduct a decadal survey, Mars was ascendant. NASA had flown a series of Mars missions and was working on its most ambitious rover yet, Curiosity.
The situation is somewhat different in the latest planetary science decadal survey, published April 19 by a National Academies committee.
NASA's Voyager 1 is sending mysterious data from beyond our solar system.
The veteran spacecraft has been exploring our solar system and interstellar space since 1977.It is now 14.5 billion miles away from Earth, making it the most distant human-made object.
NASA's Voyager 1 is continuing its journey beyond our solar system, 45 years after it was launched. But now the veteran spacecraft is sending back strange data, puzzling its engineers.
Stone found in Egypt hides first clues of the biggest explosion in universe - SCIENCE News
It was in 2013 that researchers announced that a small pebble found in southwest Egypt was not from Earth. Two years later, analysis showed it was not part of any known types of meteorite or comet.
Forensic analysis of the stone reveals that it could be the first tangible evidence on Earth of a supernova type of explosion.
3D porosity structure of the earliest solar system material | Scientific Reports
Carbonaceous chondrites (CCs) contain the earliest preserved Solar System material, and objects containing this material are targets of numerous sample return missions.

How to avoid 'bad actors' in booming solar industry | MPR News
Frank and Angela Haynes wanted to put solar panels on their century-old home in Albany, about 20 miles west of St. Cloud.
Frank Haynes worked for an electric utility years ago, when most electricity was produced by burning coal. He knew that solar is becoming an affordable energy alternative to reduce fossil fuel use, which produces greenhouse gasses that contribute to climate change.
Mars lander losing power because of dust on solar panels - ABC News
NASA's Mars lander, called Insight, is slowly losing power because its two solar panels are covered in dust and it will need to mostly shut down by the end of May.
Morever, the dust levels in the atmosphere are only increasing and sunlight is decreasing as Mars enters winter, which is speeding up the loss of power.
