VALLES MARINERIS, MARS - Mars' own Grand Canyon, Valles Marineris, is shown on the surface of the planet in this composite image made aboard NASA's Mars Odyssey spacecraft. The image was taken from a video featuring high-resolution images from Arizona State University's Thermal Emission Imaging System multi-band camera on board the spacecraft. The mosaic was then colored to approximate how Mars would look to the human eye. Valles Marineris is 10 times longer, five times deeper and 20 times wider than Earth's Grand Canyon.

Neptune’s A Pale Blue Fraud!

The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/ESA/CSA James Webb Space Telescope. Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image. This galactic portrait was captured by Webb’s Mid-InfraRed Instrument (MIRI). In this image the reprocessed stellar light by dust grains and molecules in the medium of the galaxy illuminate a dramatic filamentary medium. Empty cavities and bright filaments alternate and give the impression of ripples propagating from the spiral arms. The yellow compact regions indicate the newly formed star clusters in the galaxy. M51 — also known as NGC 5194 — lies about 27 million light-years away from Earth in the constellation Canes Venatici, and is trapped in a tumultuous relationship with its near neighbour, the dwarf galaxy NGC 5195. The interaction between these two galaxies has made these galactic neighbours one of the better-studied galaxy pairs in the night sky. The gravitational influence of M51’s smaller companion is thought to be partially responsible for the stately nature of the galaxy’s prominent and distinct spiral arms. If you would like to learn more about this squabbling pair of galactic neighbours, you can explore earlier observations of M51 by the NASA/ESA Hubble Space Telescope here.  This Webb observation of M51 is one of a series of observations collectively titled Feedback in Emerging extrAgalactic Star clusTers, or FEAST. The FEAST observations were designed to shed light on the interplay between stellar feedback and star formation in environments outside of our own galaxy, the Milky Way. Stellar feedback is the term used to describe the outpouring of energy from stars into the environments which form them, and is a crucial process in determining the rates at which stars form. Understanding stellar feedback is vital to building accurate universal models of star formation. The aim of the FEAST observations is to discover and study stellar nurseries in galaxies beyond our own Milky Way. Before Webb became operative, other observatories such as the Atacama Large Millimetre Array in the Chilean desert and Hubble have given us a glimpse of star formation either at the onset (tracing the dense gas and dust clouds where stars will form) or after the stars have destroyed with their energy their natal gas and dust clouds. Webb is opening a new window into the early stages of star formation and stellar light, as well as the energy reprocessing of gas and dust. Scientists are seeing star clusters emerging from their natal cloud in galaxies beyond our local group for the first time. They will also be able to measure how long it takes for these stars to pollute with newly formed metals and to clean out the gas (these time scales are different from galaxy to galaxy). By studying these processes, we will better understand how the star formation cycle and metal enrichment are regulated within galaxies as well as what are the time scales for planets and brown dwarfs to form. Once dust and gas is removed from the newly formed stars, there is no material left to form planets. [Image Description: A large spiral galaxy takes up the entirety of the image. The core is mostly bright white, but there are also swirling, detailed structures that resemble water circling a drain. There is white and pale blue light that emanates from stars and dust at the core’s centre, but it is tightly limited to the core. The detailed rings feature bands of deep orange and cloudy grey, which are interspersed by darker empty regions throughout.]

Voyager 2 Has A Few Last Things To Say

Paleoanthropologist and National Geographic Explorer-in-Residence, Professor Lee Rogers Berger holds a replica of the skull of "NEO" a new skeleton fossil findings of the Homo Naledi Hominin species at the cradle of Human Kind in Maropeng near Johannesburg on May, 9 2017 in South Africa. Primitive hominids may have lived in Africa at the same time as humans, researchers said Tuesday, in new findings that could change the understanding of human evolution. Fossils found deep in South Africa's Rising Star cave complex in 2013 have been dated by several expert teams with their findings suggesting the hominids, called Homo naledi, may have lived alongside Homo sapiens. It had previously been thought that the hominids were millions of years old. A team of 20 scientists from laboratories and institutions around the world, including in South Africa and Australia, established the age of the fossils which suggests that Homo naledi may well have lived at the same time as humans.
