Cosmonauts at work | International Space Station

ESA Astronaut Alexander Gerst: "The ultimate workplace. Cosmonauts Oleg Artemyev and Sergey Prokopyev successfully installed the Icarus experiment antenna on the outside hull of the International Space Station during 7 hour 46 minute-long spacewalk—RS-EVA-45."

"Der abgelegenste Arbeitsplatz"
"Der abgelegenste Arbeitsplatz der Welt. Meine Freunde Oleg und Sergey haben eben erfolgreich die Antenne des Icarus Experiments auf der Außenhülle der ISS installiert."

Icarus is a collaborative environmental experiment between Germany and Russia that studies the migratory patterns of small animals on Earth. It consists of an antenna and GPS hardware to track the movements of animals that have been tagged with small GPS receivers. The experiment may provide data about how animals move from one location to another, how animal population density shifts over time, and how diseases spread.

Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos have completed a spacewalk lasting 7 hours and 46 minutes.

The two cosmonauts opened the hatch to the Pirs docking compartment to begin the spacewalk at 12:17 p.m. EDT on August 15, 2018. They re-entered the airlock and closed the hatch at 8:03 p.m. EDT.

During the spacewalk, the duo manually launched four small technology satellites and installed an experiment called Icarus onto the Russian segment of the space station.

It was the 212th spacewalk in support of International Space Station assembly, maintenance and upgrades, the third in Artemyev’s career and the first for Prokopyev.

What Does the Discovery of #MorePlanetsThanStars Mean to You? | NASA

The Kepler space telescope has had a profound impact on our understanding of the number of worlds that exist beyond our solar system. Through its survey, we’ve discovered there are more planets than stars in our galaxy! After nine amazing years in space, Kepler’s journey is coming to an end. Before we say farewell to the spacecraft, NASA invites you to celebrate its legacy by sharing something about what the finding of “more planets than stars” means to you. Tag your posts on social media with the hashtag #MorePlanetsThanStars.

Saturn's Translucent Arcs | NASA Cassini Mission

Saturn’s rings are perhaps the most recognized feature of any world in our solar system. Cassini spent more than a decade examining them more closely than any spacecraft before it. The rings are made mostly of particles of water ice that range in size from smaller than a grain of sand to as large as mountains. The ring system extends up to 175,000 miles (282,000 kilometers) from the planet, but for all their immense width, the rings are razor-thin, about 30 feet (10 meters) thick in most places.

From the right angle you can see straight through the rings, as in this natural-color view that looks from south to north. Cassini obtained the images that comprise this mosaic on April 25, 2007, at a distance of approximately 450,000 miles (725,000 kilometers) from Saturn. The Cassini spacecraft ended its mission on Sept. 15, 2017.

The Cassini mission was a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

The Moon, Argentina & Chile | International Space Station

U.S. Astronaut Ricky Arnold: "A curious moon peeks over the horizon at Tierra del Feugo, Argentina and Chile."

Tierra del Fuego is an archipelago at South America’s southernmost tip, shared by Chile and Argentina. It is known for its dramatic landscape of snowy mountains, glaciers, tundra and wind-sculpted trees. Its main island, Isla Grande, is home to the Argentine resort town of Ushuaia. Sometimes called “the End of the World,” Ushuaia is a gateway to the region and Antarctica to the south.

A fulldome family portrait | ESO

This fulldome view of the Very Large Telescope (VLT), at ESO’s Paranal Observatory, shows almost all of the telescope’s constituent units in one family photograph!

ESO's VLT comprises four large 8.2-meter Unit Telescopes (UTs), all of which can be seen here and are recognised by their boxy appearance, and four 1.8-metre Auxiliary Telescopes (ATs), two of which are seen here flanking their bigger relatives (both with their rounded domes open). Alongside their standard designations—UT1, UT2, and so on—each of the four giant UTs has its own name in the local Chilean Mapuche language: Antu (The Sun), Kueyen (The Moon), Melipal (The Southern Cross), and Yepun (Venus).

The yellow laser streaking up into the night sky, launched by one of the UTs, creates an artificial star high in the atmosphere, fittingly known as a Laser Guide Star (LGS). This ‘star’ is part of the telescope’s adaptive optics system, which allows astronomers to compensate for the effects of atmospheric turbulence and achieve far clearer images.

The image was created by ESO Photo Ambassador Petr Horálek, and is a puzzle made up of numerous different pictures stitched together to form this high resolution panorama.

Galactic treasure chest | Hubble

Galaxies abound in this spectacular Hubble image; spiral arms swirl in all colors and orientations, and fuzzy ellipticals can be seen speckled across the frame as softly glowing smudges on the sky. Each visible speck of a galaxy is home to countless stars. A few stars closer to home shine brightly in the foreground, while a massive galaxy cluster nestles at the very center of the image; an immense collection of maybe thousands of galaxies, all held together by the relentless force of gravity.

Galaxy clusters are some of the most interesting objects in the cosmos. They are the nodes of the cosmic web that permeates the entire Universe—to study them is to study the organisation of matter on the grandest of scales. Not only are galaxy clusters ideal subjects for the study of dark matter and dark energy, but they also allow the study of farther-flung galaxies. Their immense gravitational influence means they distort the spacetime around them, causing them to act like giant zoom lenses. The light of background galaxies is warped and magnified as it passes through the galaxy cluster, allowing astronomers insight into the distant—and therefore early—Universe.

This image was taken by Hubble’s Advanced Camera for Surveys and Wide-Field Camera 3 as part of an observing programme called RELICS (Reionization Lensing Cluster Survey). RELICS imaged 41 massive galaxy clusters with the aim of finding the brightest distant galaxies for the forthcoming NASA/ESA/CSA James Webb Space Telescope (JWST) to study.

Dr. Eugene Parker Watches NASA Parker Solar Probe Launch

First NASA Mission Named for a Living Person

In 1958, Dr. Parker published the first paper theorizing the solar wind, the Sun's constant outflow of material. Now, the Parker Solar Probe is on its way to the Sun to make novel measurements of the solar wind and help us uncover its secrets. 

Image: Dr. Eugene Parker, a pioneer in heliophysics at the University of Chicago, watches the launch of NASA's Parker Solar Probe. This is the first agency mission named for a living person. The liftoff took place at 3:31 a.m. EDT on Sunday, Aug. 12, 2018. The spacecraft was built by the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.
