What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere.

"Ever stared down the gaping eye of a category 4 hurricane? It's chilling, even from space," says European Space Agency astronaut Alexander Gerst, who is currently living and working aboard the International Space Station as a member of the Expedition 56 crew.

Just ask those who've been around the block a few times and carry a lot more baggage.

First came the trees. In the town of Salamanca, Spain, the photographer noticed how distinctive a grove of oak trees looked after being pruned. Next came the galaxy.

On August 23, 2018 the identification and distribution of aerosols in the Earth's atmosphere is shown in this dramatic, planet-wide visualization. Produced in real time, the Goddard Earth Observing System Forward Processing (GEOS FP) model relies on a combination of Earth-observing satellite and ground-based data to calculate the presence of types of aerosols, tiny solid particles and liquid droplets, as they circulate above the entire planet. This August 23rd model shows black carbon particles in red from combustion processes, like smoke from the fires in the United States and Canada, spreading across large stretches of North America.

Hard to imagine, but it is the truth about success.

It doesn't exist. So get moving.

They add up over time.

What kind of clouds are these? Although their cause is presently unknown, such unusual atmospheric structures, as menacing as they might seem, do not appear to be harbingers of meteorological doom. Formally recognized as a distinct cloud type only last year, Asperitas clouds can be stunning in appearance, unusual in occurrence, and are relatively unstudied. Whereas most low cloud decks are flat bottomed, asperitas clouds appear to have significant vertical structure underneath.

It takes a lot of variables to create the perfect environment for true purpose.

Uluru. Needs no explanation. Truly difficult to capture the massiveness of this sandstone formation. Every cleft and imperfection has cultural/"Dreamtime" significance. Unfortunately, the bush flies kept me from staying longer. You can see the smoke from controlled spinifex burnings begins the rock. You can see in the middle, a group of people walking on top. Picking up some Aboriginal hitchhikers, their first question was if I had climbed it.

The Earth, in all its majesty and its tragedy, is the subject of images taken aboard the International Space Station. This image of the Carr and Ferguson fires was captured by European Space Agency astronaut Alexander Gerst (@Astro_Alex), on August 3, 2018, from the station. "California burning. These fires are frightening to watch, even from space. Here's a shout-out from space to all firefighters on this planet, my former colleagues. Stay safe my friends!" Gerst, a geophysicist and volcanologist, wrote on his Twitter account.

Mars is also known as The Red Planet, often seen with a reddish tinge in dark night skies. Mars shines brightly at the upper left of this gorgeous morning twilight view from Mornington Peninsula, Victoria, Australia, but the Moon and planet Earth look redder still. Taken on July 27, the totally eclipsed Moon is setting. It looks reddened because the Earth's umbral shadow isn't completely dark. Instead Earth's shadow is suffused with a faint red light from all the planet's sunsets and sunrises seen from the perspective of an eclipsed Moon.
