This beautiful clump of glowing gas, dark dust, and glittering stars is the spiral galaxy NGC 4248, located about 24 million light-years away in the constellation of Canes Venatici (The Hunting Dogs).
This image was produced by the NASA/ESA Hubble Space Telescope as it embarked upon compiling the first Hubble ultraviolet “atlas”, for which the telescope targeted 50 nearby star-forming galaxies. A sample spanning all kinds of different morphologies, masses, and structures. Studying this sample can help us to piece together the star-formation history of the Universe.
By exploring how massive stars form and evolve within such galaxies, astronomers can learn more about how, when, and where star formation occurs, how star clusters change over time, and how the process of forming new stars is related to the properties of both the host galaxy and the surrounding interstellar medium (the “stuff” that fills the space between individual stars).
This image is formed of observations from Hubble’s Wide Field Camera 3.

Approximately 95 million light-years away, in the southern constellation of Octans (The Octant), lies NGC 7098—an intriguing spiral galaxy with numerous sets of double features. The first of NGC 7098’s double features is a duo of distinct ring-like structures that loop around the galaxy’s hazy heart. These are NGC 7098’s spiral arms, which have wound themselves around the galaxy’s luminous core. This central region hosts a second double feature: a double bar.
NGC 7098 has also developed features known as ansae, visible as small, bright streaks at each end of the central region. Ansae are visible areas of overdensity—they commonly take looping, linear, or circular shapes, and can be found at the extremities of planetary ring systems, in nebulous clouds, and, as is the case with NGC 7098, in parts of galaxies that are packed to the brim with stars.
This image is formed from data gathered by the FOcal Reducer and low dispersion Spectrograph (FORS) instrument, installed on ESO’s Very Large Telescope at Paranal Observatory. An array of distant galaxies are also visible throughout the frame, the most prominent being the small, edge-on, spiral galaxy visible to the left of NGC 7098, known as ESO 048-G007.

July 20, 2017: While photographing Mars, NASA’s Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Discovered in 1877, the diminutive, potato-shaped moon is so small that it appears star-like in the Hubble pictures. Phobos orbits Mars in just 7 hours and 39 minutes, which is faster than Mars rotates. The moon’s orbit is very slowly shrinking, meaning it will eventually shatter under Mars’ gravitational pull, or crash into the planet.

NASA's Aqua satellite passed over the Eastern Pacific Ocean's Hurricane Fernanda as it continued to track toward the Central Pacific. The storm continues to move over cooler waters and is on a weakening trend.
The storm's eye is now cloud-filled.
July 18, 2017: On July 17 at 6:10 p.m. EDT (2210 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible picture of Fernanda. The image revealed strong thunderstorms continued to circle the low-level center of circulation, and the eye of the storm had become filled in from clouds.
At 5 a.m. EDT (0900 UTC), the center of Hurricane Fernanda was located near 15.4 degrees north latitude and 132.8 degrees west longitude. That's about 1,495 miles (2,410 km) east of Hilo, Hawaii. Fernanda was moving toward the northwest near 9 mph (15 kph) and this general motion is expected during the next day or so. A turn to the west-northwest is expected on Wednesday. The estimated minimum central pressure is 971 millibars.
Maximum sustained winds are near 105 mph (165 kph) with higher gusts. Continued gradual weakening is forecast during the next couple of days.

A flare medium-sized (M2) flare and a coronal mass ejection erupted from the same, large active region (July 14, 2017). The flare lasted almost two hours, quite a long duration. Coronagraphs on the SOHO spacecraft show a substantial cloud of charged particles blasting into space just after the blast. The coils arcing over this active region are particles spiraling along magnetic field lines, which were reorganizing themselves after the magnetic field was disrupted by the blast. Images were taken in a wavelength of extreme ultraviolet light.

Image: Neil Armstrong in flight suit with lunar module simulator in 1969.
When the United States set a goal of landing a man on the moon, NASA Langley Research Center tackled the many challenges of spaceflight, trained astronauts, managed Project Mercury, and assumed major roles in both the Gemini and Apollo programs. Langley led the Lunar Orbiter initiative, which not only mapped the moon, but chose the spot for the first human landing. Langley aerospace engineer John Houbolt championed the lunar-orbit rendezvous concept, enabling the Apollo 11 moon landing and the safe return of its crew to Earth.
Neil Armstrong, the first human to set foot on the lunar surface, trained at Langley's Lunar Landing Research Facility on equipment that cancelled all but one-sixth of Earth's gravitational force to match that of the moon's. This photograph shows Armstrong at the Lunar Landing Research Facility on Feb. 12, 1969. Twenty-four astronauts practiced touchdowns at the facility, where overhead cables supported five-sixths of the weight of a full-size model lander, and thrust was provided by a working rocket engine.
Part of the landing facility was the Reduced Gravity Simulator, which was attached to an overhead, lightweight trolley track. There, suspended on one side by a network of slings and cables, an astronaut's ability to walk, run, and perform the various tasks required during lunar excursions was evaluated.
Armstrong offered what was perhaps the greatest tribute to the importance of his Langley training in Apollo 11's success. When asked what it was like to land on the moon, he replied: "Like Langley."

This intriguing surface texture is the result of rock interacting with water. The rock was then eroded and later exposed to the surface. The pinkish, almost dragon-like scaled texture represents Martian bedrock that has specifically altered into a clay-bearing rock.
The nature of the water responsible for the alteration, and how it interacted with the rock to form the clay remains poorly understood. Not surprisingly, the study of such altered rocks on Mars is an area of active investigation by the Mars science community. Understanding such interactions, and how they happened, help scientists to understand the past climate on Mars, and if the red planet ever harbored life.
Recent studies indicate that the early Martian climate may not have been as warm, wet, and Earth-like, as previously suggested. This is not a problem for finding life on Mars as one might think. Ongoing studies of dry and cold environments on Earth shows that life finds ways to adapt to such extremes. Such work provides hope for finding evidence for life on other planets, like Mars, someday.

This enhanced-color image of Jupiter's Great Red Spot was created by citizen scientist Gerald Eichstädt using data from the JunoCam imager on NASA's Juno spacecraft. | July 12, 2017: Images of Jupiter's Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam imager aboard NASA's Juno mission snapped pics of the most iconic feature of the solar system's largest planetary inhabitant during its Monday (July 10) flyby. The images of the Great Red Spot were downlinked from the spacecraft's memory on Tuesday and placed on the mission's JunoCam website Wednesday morning.
"For hundreds of years scientists have been observing, wondering and theorizing about Jupiter's Great Red Spot," said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. "Now we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Juno's eight science instruments, to shed some new light on the past, present and future of the Great Red Spot."
As planned by the Juno team, citizen scientists took the raw images of the flyby from the JunoCam site and processed them, providing a higher level of detail than available in their raw form. The citizen-scientist images, as well as the raw images they used for image processing, can be found at:
https://www.missionjuno.swri.edu/junocam/processing
"I have been following the Juno mission since it launched," said Jason Major, a JunoCam citizen scientist and a graphic designer from Warwick, Rhode Island. "It is always exciting to see these new raw images of Jupiter as they arrive. But it is even more thrilling to take the raw images and turn them into something that people can appreciate. That is what I live for."
Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiter's Great Red Spot is 1.3 times as wide as Earth. The storm has been monitored since 1830 and has possibly existed for more than 350 years. In modern times, the Great Red Spot has appeared to be shrinking.
All of Juno's science instruments and the spacecraft's JunoCam were operating during the flyby, collecting data that are now being returned to Earth. Juno's next close flyby of Jupiter will occur on Sept. 1.
Juno reached perijove (the point at which an orbit comes closest to Jupiter's center) on July 10 at 6:55 p.m. PDT (9:55 p.m. EDT). At the time of perijove, Juno was about 2,200 miles (3,500 kilometers) above the planet's cloud tops. Eleven minutes and 33 seconds later, Juno had covered another 24,713 miles (39,771 kilometers), and was passing directly above the coiling, crimson cloud tops of the Great Red Spot. The spacecraft passed about 5,600 miles (9,000 kilometers) above the clouds of this iconic feature.
Juno launched on Aug. 5, 2011, from Cape Canaveral, Florida. During its mission of exploration, Juno soars low over the planet's cloud tops -- as close as about 2,100 miles (3,400 kilometers). During these flybys, Juno is probing beneath the obscuring cloud cover of Jupiter and studying its auroras to learn more about the planet's origins, structure, atmosphere and magnetosphere.
Early science results from NASA's Juno mission portray the largest planet in our solar system as a turbulent world, with an intriguingly complex interior structure, energetic polar aurora, and huge polar cyclones.
"These highly-anticipated images of Jupiter's Great Red Spot are the 'perfect storm' of art and science. With data from Voyager, Galileo, New Horizons, Hubble and now Juno, we have a better understanding of the composition and evolution of this iconic feature," said Jim Green, NASA's director of planetary science. "We are pleased to share the beauty and excitement of space science with everyone."

The Great Red Spot (GRS) in Jupiter's southern hemisphere has delighted and mystified since its discovery in the 17th Century. With its swirl of reddish hues, it is 2-3 times as wide as Earth and is seen by many as a “perpetual hurricane,” with winds peaking at about 400 miles an hour.

Image: The giant molecular cloud known as W51 is one of the closest to Earth at a distance of about 17,000 light years.
July 12, 2017: In the context of space, the term ‘cloud’ can mean something rather different from the fluffy white collections of water in the sky or a way to store data or process information. Giant molecular clouds are vast cosmic objects, composed primarily of hydrogen molecules and helium atoms, where new stars and planets are born. These clouds can contain more mass than a million suns, and stretch across hundreds of light years.
The giant molecular cloud known as W51 is one of the closest to Earth at a distance of about 17,000 light years. Because of its relative proximity, W51 provides astronomers with an excellent opportunity to study how stars are forming in our Milky Way galaxy.
A new composite image of W51 shows the high-energy output from this stellar nursery, where X-rays from Chandra are colored blue. In about 20 hours of Chandra exposure time, over 600 young stars were detected as point-like X-ray sources, and diffuse X-ray emission from interstellar gas with a temperature of a million degrees or more was also observed. Infrared light observed with NASA’s Spitzer Space Telescope appears orange and yellow-green and shows cool gas and stars surrounded by disks of cool material.
W51 contains multiple clusters of young stars. The Chandra data show that the X-ray sources in the field are found in small clumps, with a clear concentration of more than 100 sources in the central cluster, called G49.5−0.4 (pan over the image to find this source.)
Although the W51 giant molecular cloud fills the entire field-of-view of this image, there are large areas where Chandra does not detect any diffuse, low energy X-rays from hot interstellar gas. Presumably dense regions of cooler material have displaced this hot gas or blocked X-rays from it.
One of the massive stars in W51 is a bright X-ray source that is surrounded by a concentration of much fainter X-ray sources, as shown in a close-up view of the Chandra image. This suggests that massive stars can form nearly in isolation, with just a few lower mass stars rather than the full set of hundreds that are expected in typical star clusters.
Another young, massive cluster located near the center of W51 hosts a star system that produces an extraordinarily large fraction of the highest energy X-rays detected by Chandra from W51. Theories for X-ray emission from massive single stars can't explain this mystery, so it likely requires the close interaction of two very young, massive stars. Such intense, energetic radiation must change the chemistry of the molecules surrounding the star system, presenting a hostile environment for planet formation.
A paper describing these results, led by Leisa Townsley (Penn State), appeared in the July 14th 2014 issue of The Astrophysical Journal Supplement Series and is available online: https://arxiv.org/abs/1403.2576
