NASA Measures Impact of Solar Flare on Earth's Atmosphere - A key NASA instrument that can directly measure the impact of solar events on the Earth’s upper atmosphere has weighed in on the huge flare that impacted Earth last week. The flare was considered one of the largest solar events in years even though its impact on the power grid and communications was minimal due to the angle it hit Earth.
https://flic.kr/p/gwaHNf | Hebes Chasma | This mosaic of Hebes Chasma is composed of eight single images taken with the High Resolution Stereo Camera on Mars Express, corresponding to orbits 360 (2 May 2004), 2149 (16 September 2005), 3217 (12 July 2006), 5142 (3 January 2008), 5160 (8 January 2008), 5178 (13 January 2008), 6241 (11 November 2008), and 7237 (24 August 2009). The image centre lies at about 1°S / 284°E. Hebes Chasma is an enclosed, almost 8 km-deep trough stretching 315 km…
The Moon is Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits . It is the second-densest satellite among those whose densities are known .
Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world, the Blue Planet, or by its Latin name, Terra. Earth formed approximately 4.54 billion years ago by accretion from the solar nebula, and life appeared on its surface within one billion years.
A landslide-riddled part of the Martian canyon Ius Chasma is seen in a new image by the European Space Agency's High Resolution Stereo Camera. Spanning 584 miles (940 kilometers), Ius Chasma forms the northern boundary between the western half of an enormous valley system called Valles Marineris and the Martian highlands. In the same process that formed Earth's East African Rift, the Martian crust split and formed the gigantic canyon system, one of the solar system's largest.
The Jovian cloudscape boasts the most spectacular light show in the solar system, with northern and southern lights to dazzle even the most jaded space traveler. Jupiter's auroras are hundreds of times more powerful than Earth's, and they form a glowing ring around each pole that's bigger than our home planet. Revolving outside this auroral oval are the glowing, electric “footprints” of Jupiter's three largest moons.
