It's not only great that we can go to all the Planets and Moons of the Solar system but when we get there we can take such great HD photos.

What a great photo!

NASA Dawn Reveals Recent Changes in Ceres’ Surface 

Ceres’ Juling Crater

This view from NASA’s Dawn mission shows where ice has been detected in the northern wall of Ceres’ Juling Crater, which is in almost permanent shadow.

Observations of Ceres have detected recent variations in its surface, revealing that the only dwarf planet in the inner solar system is a dynamic body that continues to evolve and change.

NASA’s Dawn mission has found recently exposed deposits that give us new information on the materials in the crust and how they are changing, according to two papers published March 14 in Science Advances that document the new findings.

Observations obtained by the visible and infrared mapping spectrometer (VIR) on the Dawn spacecraft previously found water ice in a dozen sites on Ceres. The new study revealed the abundance of ice on the northern wall of Juling Crater, a crater 12 miles (20 kilometers) in diameter. The new observations, conducted from April through October 2016, show an increase in the amount of ice on the crater wall.

Great read Doone. That's why I love Astronomy and Cosmology. When I first read a Brief history of time, it blew my mind away.

Galaxies hide some of the biggest mysteries of the Universe and could one day provide more precise insights into how our cosmos evolved over the last 13.8 billion years. The distant worlds vary in so many ways, but for the first time ever, astronomers have discovered something common in them — their rotational behavior.

Scientists from the International Centre for Radio Astronomy Research have found all galaxies, from small dwarf irregulars to the largest spirals, behave like clocks and take about a billion years to complete a single spin.

“It’s not Swiss watch precision,” Professor Gerhardt Meurer from the center said in a statement. “But regardless of whether a galaxy is very big or very small, if you could sit on the extreme edge of its disk as it spins, it would take you about a billion years to go all the way around.”

The group made the discovery after establishing a direct relation between the size and average interior density of galaxies with sophisticated calculations. They found if the size of two galaxies is same, their interior density will also be similar.

“You won’t find a dense galaxy rotating quickly, while another with the same size but lower density is rotating more slowly,” Meurer added.

Only Dark Matter (And Not Modified Gravity) Can Explain The Universe
There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention…
