The Milky Way’s Big Sister | Hubble

This image taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3) shows a beautiful spiral galaxy called NGC 6744. At first glance, it resembles our Milky Way albeit larger, measuring more than 200,000 light-years across compared to 100,000 light-year diameter for our home galaxy.

NGC 6744 is similar to our home galaxy in more ways than one. Like the Milky Way, NGC 6744 has a prominent central region packed with old yellow stars. Moving away from the galactic core, one can see parts of the dusty spiral arms painted in shades of pink and blue; while the blue sites are full of young star clusters, the pink ones are regions of active star formation, indicating that the galaxy is still very lively.

In 2005, a supernova, named 2005at, was discovered within NGC 6744, adding to the argument of this galaxy’s liveliness (not visible in this image). SN 2005at is a type Ic supernova, formed when a massive star collapses in itself and loses its hydrogen envelope.

Jupiter: High-Altitude Clouds | NASA Juno

This image captures a high-altitude cloud formation surrounded by swirling patterns in the atmosphere of Jupiter's North North Temperate Belt region.

The North North Temperate Belt is one of Jupiter’s many colorful, swirling cloud bands. Scientists have wondered for decades how deep these bands extend. Gravity measurements collected by Juno during its close flybys of the planet have now provided an answer. Juno discovered that these bands of flowing atmosphere actually penetrate deep into the planet, to a depth of about 1,900 miles (3,000 kilometers).

NASA’s Juno spacecraft took this color-enhanced image at 10:11 p.m. PDT on July 15, 2018 (1:11 a.m. EDT on July 16), as the spacecraft performed its 14th close flyby of Jupiter. At the time, Juno was about 3,900 miles (6,200 kilometers) from the planet's cloud tops, above a latitude of 36 degrees.

Citizen scientist Jason Major created this image using data from the spacecraft’s JunoCam imager.

Blue Origin New Shepard Mission 9 Launch Webcast

Launch is at the 34 minute mark
New Shepard flew for the ninth time on July 18, 2018. During this mission, known as Mission 9 (M9), the escape motor was fired shortly after booster separation. The Crew Capsule was pushed hard by the escape test and we stressed the rocket to test that astronauts can get away from an anomaly at any time during flight. The mission was a success for both the booster and capsule. Most importantly, astronauts would have had an exhilarating ride and safe landing.

This is not the first time we have done this type of extreme testing on New Shepard. In October of 2012, we simulated a booster failure on the launch pad and had a successful escape. Then in October 2016, we simulated a booster failure in-flight at Max Q, which is the most physically strenuous point in the flight for the rocket, and had a completely successful escape of the capsule.

This test on M9 allowed us to finally characterize escape motor performance in the near-vacuum of space and guarantee that we can safely return our astronauts in any phase of flight.

Also on M9, New Shepard carried science and research payloads from commercial companies, universities and space agencies.

Mount Rainier | International Space Station

Stratovolcano Mount Rainier is pictured as the International Space Station orbited about 256 miles above the state of Washington in the United States.

Mount Rainier is the highest mountain of the Cascade Range of the Pacific Northwest, and the highest mountain in the U.S. state of Washington. It is a large active stratovolcano located 59 miles (95 km) south-southeast of Seattle, in the Mount Rainier National Park. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m).

Mt. Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. Because of its large amount of glacial ice, Mt. Rainier could produce massive lahars that could threaten the entire Puyallup River valley, and poses a grave threat to the southern sections of the 3.7-million-resident Seattle metropolitan area.

Sunglint on the Atlantic | International Space Station

The International Space Station orbited over New England and across Canada capturing the Sun's glint on the North Atlantic Ocean just off the North American coast. That gleam is caused by sunglint, an optical phenomenon that occurs when sunlight reflects off the surface of water at the same angle that one views it. The result is a mirror-like specular reflection of sunlight off the water and back at the astronaut and their camera.

Jupiter and Europa | Hubble

Judy: "The Great Red Spot is still kinda great, but it's getting smaller and smaller as time wears on. At some point, it may just be a regular red spot. Still, it remains a striking feature, and it is nice that it was facing the telescope when these observations were taken."

"Bright, icy Europa is just about finished transiting the impressively sized planet and can be seen near the top."

The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anticyclonic storm 22° south of the planet's equator. It has been continuously observed for 188 years, since 1830. Earlier observations from 1665 to 1713 are believed to be of the same storm; if this is correct, it has existed for at least 350 years. Such storms are not uncommon within the turbulent atmospheres of gas giants.

Europa is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet. It is also the sixth-largest moon in the Solar System. Europa was discovered in 1610 by Galileo Galilei.

Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron–nickel core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is striated by cracks and streaks, whereas craters are relatively rare. In addition to Earth-bound telescope observations, Europa has been examined by a succession of space probe flybys, the first occurring in the early 1970s.

Europa has the smoothest surface of any known solid object in the Solar System. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably harbor extraterrestrial life. The predominant model suggests that heat from tidal flexing causes the ocean to remain liquid and drives ice movement similar to plate tectonics, absorbing chemicals from the surface into the ocean below. Sea salt from a subsurface ocean may be coating some geological features on Europa, suggesting that the ocean is interacting with the seafloor. This may be important in determining if Europa could be habitable.

Namib Desert, Africa | International Space Station

U.S. Astronaut Ricky Arnold: "The ethereal beauty of Earth is our constant companion. It reminds us of all that we have left behind and what awaits when we return. The Skeleton Coast of the Namib Desert."

The Skeleton Coast is the northern part of the Atlantic coast of Namibia and south of Angola from the Kunene River south to the Swakop River, although the name is sometimes used to describe the entire Namib Desert coast. The Bushmen of the Namibian interior called the region "The Land God Made in Anger", while Portuguese sailors once referred to it as "The Gates of Hell".

The Namib is a coastal desert in southern Africa. The name Namib is of Nama origin and means "vast place". According to the broadest definition, the Namib stretches for more than 2,000 kilometers (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa.

Polar Mesopheric Clouds | International Space Station

ESA Astronaut Alexander Gerst: "High, cold and icy. These polar mesospheric clouds are still a mystery to science, but the Space Storm Hunter outside Columbus is investigating. At around 80 km altitude, they often reflect the sun while Earth underneath is already dark, appearing noctilucent."

Polaren Höhenwolken
"Hoch, kalt, eisig. Diese polaren Höhenwolken über Nordeuropa sind immer noch ein Rätsel, doch unser ASIM-Experiment untersucht es bereits. In 80 km Höhe reflektieren sie oft noch Sonnenlicht, wenn die Erde darunter bereits dunkel ist, und erscheinen nachtleuchtend."

U.S. Cygnus Cargo Spacecraft Release

Expedition 56 Flight Engineers Alexander Gerst of the European Space Agency (ESA) and Serena Auñón-Chancellor of NASA commanded the International Space Station’s Canadarm2 robotic arm to release the Cygnus cargo spacecraft at 8:37 a.m. EDT on July 15, 2018. At the time of release, the station was flying 253 miles above the southeastern border of Colombia. Earlier, ground controllers used the robotic arm to unberth Cygnus.

The departing spacecraft moved a safe distance away from the space station before deploying a series of CubeSats. Cygnus will remain in orbit for two more weeks to allow a flight control team to conduct engineering tests.

Cynus is scheduled to deorbit with thousands of pounds of trash on Monday, July 30, as it burns up harmlessly over the Pacific Ocean while entering the Earth’s atmosphere.

The spacecraft arrived on station May 24 delivering cargo for Orbital ATK’s (now Northrop Grumman’s) ninth contracted mission under NASA’s Commercial Resupply Services contract.

Eagle Nebula: A Quick Look | NASA Chandra

July 16, 2018: New stars form in clusters containing large amounts of dust and gas, including structures like the Pillars of Creation. A newly forming star is located near the tip of the largest Pillar.

The atmospheres of young stars produce X-ray emission, and disks of dust and gas surrounding many of them produce infrared light. Astronomers combine X-ray and infrared data to study the behavior of young stars.

X-ray activity in young stars with disks is, on average, a few times less intense that in young stars without disks.
