Planetary Image of the Day – Week of June 14, 2021


Week of June 14, 2021

Welcome to our weekly recap of our Planetary Image of the Day (PPOD)!
Fantastic planetary surfaces, a moon that looks like food, and a sunrise like no other.

Stunning northern polar layers of Mars
MRO spacecraft height – 318.1 km (197.7 miles).

Stratified deposits at the North Pole are a 3 km thick cluster of powdery ice caps about 1000 km in diameter. The layers record information about the climate going back a few million years in Martian history.

In many places, erosion has created escarpments and canals that expose these layers. The beige colored layers are the dusty water ice of layered polar deposits; however, a section of bluish layers is visible below them. These bluish layers contain sand-sized rock fragments that likely formed a vast field of polar dunes before the dusty ice that covered it settled.

The absence of a polar ice cap at this bygone era attests to the variability of the Martian climate, which undergoes greater changes over time than that of Earth.

Partial solar eclipse from Nahant beach
By Babak A. Tafreshi, https://buff.ly/3pRJGCU via The World at Night – TWAN

The partial solar eclipse at Nahant Beach in Massachusetts on June 10, 2021
A sunrise like no other. This morning at 5 a.m., near my home in the Boston area, I was waiting for the partially eclipsed sun to rise from a clear ocean horizon, but an approaching high cloud layer changed the plan. Soon they acted as a natural filter and the view was spectacular through the telephoto lens but not to the naked eye due to the scattering effect of the clouds.

Jupiter by Juno

Jupiter by Juno
NASA’s Juno spacecraft captured this incredibly detailed look at a cyclonic storm in Jupiter’s atmosphere. The vortex seen here is approximately 1,200 miles (2,000 kilometers) wide. Jupiter is mainly composed of hydrogen and helium, but some of the color of its clouds can come from plumes of gas containing sulfur and phosphorus rising from the warmer interior of the planet. Citizen scientist Kevin M. Gill created this image using data from the spacecraft’s JunoCam imager. It was taken on November 3, 2019 at 2:08 p.m. PST (5:08 p.m. EST). At the time, the spacecraft was about 5,300 miles (8,500 kilometers) from Jupiter’s cloud tops above about 49 degrees latitude.

The Nile Delta seen from space
“The world is big but some areas are immediately recognizable, like the Nile Valley and its delta.”

Pan, imaged by Cassini
Saturn’s small moon Pan, which orbits within the Encke Gap of Saturn’s rings. A thin “skirt” or ridge of material surrounds the equator of the moon, giving it a “ravioli” or “dumpling” appearance.
