Jupiter’s North: Time-lapse Sequence | NASA Juno

Striking atmospheric features in Jupiter’s northern hemisphere are captured in this series of color-enhanced images from NASA’s Juno spacecraft. An anticyclonic white oval, called N5-AWO, can be seen at center left of the first image (at far left) and appears slightly higher in the second and third images. A tempest known as the Little Red Spot is visible near the bottom of the second and third images. The reddish-orange band that is prominently displayed in the fourth and fifth images is the North North Temperate Belt.

From left to right, this sequence of images was taken between 9:54 p.m. and 10:11 p.m. PDT on July 15 (12:54 a.m. and 1:11 a.m. EDT on July 16), as the spacecraft performed its 14th close flyby of Jupiter. At the time, Juno’s altitude ranged from about 15,700 to 3,900 miles (25,300 to 6,200 kilometers) from the planet's cloud tops, above a latitude of approximately 69 to 36 degrees.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft’s JunoCam imager.

GOODS-South Hubble Deep UV Legacy Field | Hubble

This week we showcase the second part of the Hubble Deep UV (HDUV) Legacy Field, the GOODS-South view. With the addition of new ultraviolet light imagery, astronomers using the NASA/ESA Hubble Space Telescope have captured the largest panoramic view of the fire and fury of star birth in the distant Universe, encompassing 12,000 star-forming galaxies.

Hubble’s ultraviolet vision opens up a new window on the evolving Universe, tracking the birth of stars over the last 11 billion years up to the cosmos’s busiest star-forming period, which happened about three billion years after the Big Bang.

So far, ultraviolet light has been the missing piece of the cosmic puzzle. Now, combined with data in infrared, and visible light from Hubble and other space- and ground-based telescopes, astronomers have assembled the most comprehensive portrait yet of the Universe’s evolutionary history. The image straddles the gap between the very distant galaxies, which can only be viewed in infrared light, and closer galaxies, which can be seen across different wavelengths. The light from distant star-forming regions in remote galaxies started out as ultraviolet, but the expansion of the Universe has shifted the light into infrared wavelengths. By comparing images of star formation in the distant and nearby Universe, astronomers can get a better understanding of how nearby galaxies grew from small clumps of hot, young stars long ago.

The observation program harnessed the ultraviolet vision of Hubble’s Wide Field Camera 3. This study extends and builds on the previous Hubble multi-wavelength data in the CANDELS-Deep (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) fields within the central part of the GOODS (The Great Observatories Origins Deep Survey) fields. This mosaic is 14 times the area of the Hubble Ultraviolet Ultra Deep Field released in 2014.

V is for VLT | ESO

This Picture of the Week shows a huge celestial “V” emblazoned across the night sky over ESO’s Paranal Observatory, which is situated atop Cerro Paranal in Chile.

One arm of the “V” is noticeably clearer than the other; the right arm, pointing towards the top right corner of the frame, is traced out by the beautiful star-studded centre of the Milky Way. The fainter arm, leaning leftwards, is formed of glowing columns of diffuse zodiacal light, a phenomenon caused by incoming sunlight that is scattered by small particles of cosmic dust.

While we often see both the Milky Way and zodiacal light at Paranal thanks to the site’s famously clear skies, the “V” alignment shown here is unusual. Zodiacal light is related to the Earth’s path through space, as the dust particles responsible for scattering the sunlight are all within a cloud that lies on the ecliptic plane (dubbed the zodiacal cloud). Because of this, the glow varies in strength and visibility throughout the year, and is best seen in spring and autumn just after sunset or before sunrise. The opportunity to observe a beam of zodiacal light seeming to emanate from the very centre of the Milky Way comes only once per year, during January. For more information on this cosmic phenomenon, see ESOcast 82: Zodiacal light (esocast82a).

In the crook of the “V” sits one of ESO’s Very Large Telescope’s 1.8-metre Auxiliary Telescopes (ATs) — of which there are four in total. Each AT is housed in a robust enclosure that protects the delicate telescope and instrumentation from the harsh, arid desert conditions experienced at the site. Two other ATs are visible in the background towards the left side of the image.

The picture was taken by ESO Photo Ambassador Petr Horálek.

NASA Wishes Katherine Johnson a Happy 100th Birthday

Aug. 26, 2018: In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon to hand check the computer’s orbital equations that would control the trajectory of the capsule in John Glenn’s Friendship 7 mission, from blast off to splashdown.

“If she says they’re good,’” Katherine Johnson remembers the astronaut saying, “then I’m ready to go.” Glenn’s flight was a success, and marked a turning point in the competition between the United States and the Soviet Union in space.

NASA wishes Katherine Johnson a very Happy 100th Birthday!

The Sun: Twisting Outburst | NASA SDO

This close-up of the Sun from a two-hour period on Aug. 13, 2018 shows a minor eruption of charged particles rising up and twisting about before falling back into the Sun. Imaged in extreme ultraviolet light, these kinds of events are difficult to see except when they occur along the sun's edge, also known as the limb. At its peak the plasma rises several times the diameter of Earth.

Mount Kilimanjaro in Cloud | International Space Station

ESA Astronaut Alexander Gerst: "Can you spot Kilimanjaro sticking out of the clouds over Kenya and Tanzania, in a mountain glow just before nightfall?"

"Kilimandscharo, wie er aus den Wolken über Kenia und Tansania herausschaut. Sein Gipfel glüht noch im Sonnenuntergang."

Mount Kilimanjaro, or just Kilimanjaro, with its three volcanic cones, "Kibo", "Mawenzi", and "Shira", is a dormant volcano in Tanzania. It is the highest mountain in Africa, about 4,900 meters (16,100 ft) from its base, and 5,895 meters (19,341 ft) above sea level. (Source: Wikipedia)

Asteroid Ryugu | Japan's Hayabusa2 Spacecraft

This big space diamond has an estimated value of over 80 billion dollars. It's only diamond in shape, though—asteroid 162173 Ryugu is thought to be composed of mostly nickel and iron. Asteroids like Ryugu are interesting for several reasons, perhaps foremost because they are near the Earth and might, one day in the far future, pose an impact threat. In the nearer term, Ryugu is interesting because it may be possible to send future spacecraft there to mine it, thus providing humanity with a new source of valuable metals. Scientifically, Ryugu is interesting because it carries information about how our Solar System formed billions of years ago, and why its orbit takes it so close to Earth. Japan's robotic spacecraft Hayabusa2 just arrived at this one-kilometer wide asteroid in late June. The featured image shows surface structures unknown before spacecraft Hayabusa2's arrival, including rock fields and craters. Within the next three months, Hayabusa2 is scheduled to unleash several probes, some that will land on Ryugu and hop around, while Hayabusa2 itself will mine just a little bit of the asteroid for return to Earth.

162173 Ryugu, provisional designation 1999 JU3, is a near-Earth object and a potentially hazardous asteroid of the Apollo group. It measures approximately 1 kilometer (0.6 mi) in diameter and is a dark object of the rare spectral type Cg, with qualities of both a C-type asteroid and a G-type asteroid.

Typhoon Soulik | NASA Terra Satellite

At 10:50 a.m. Japan/Korea Standard Time (01:50 Universal Time) on August 20, 2018, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of Typhoon Soulik as it neared Japan.

The storm carried maximum sustained winds of 115 miles per hour (100 knots)—the equivalent of a category 3 storm on the Saffir-Simpson wind scale. Forecasts called for Soulik’s track to move over Japan’s Amami Islands and then curve north toward the Korean Peninsula.

Meanwhile, Typhoon Cimaron is strengthening in the Northwest Pacific Basin. Forecasts indicate it could hit Japan later in the week.

Update: On Aug. 21 at 11 a.m. EDT (1500 UTC) Joint Typhoon Warning Center or JTWC noted Typhoon Soulik was located approximately 194 nautical miles north-northeast of Kadena Air Base in Okinawa, tracking northwestward at 15 mph (13 knots/24 kph). Maximum sustained winds were near 109 mph (95 knots/176 kph).

Enceladus at Saturn | NASA Cassini

Processed using calibrated red, green, and violet filtered images of Saturn's moon Enceladus taken by the Cassini spacecraft on August 18, 2015.

Enceladus is the sixth-largest moon of Saturn. It is about 500 kilometers (310 mi) in diameter, about a tenth of that of Saturn's largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon only reaches −198 °C (−324 °F), far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrains that formed as recently as 100 million years ago.

Titan at Saturn: Close-up | NASA Cassini

Processed using calibrated red, green, and blue filtered images of Saturn's moon Titan taken by the Cassini spacecraft on December 17, 2015.

Titan is the largest moon of Saturn. It is the only moon known to have a dense atmosphere, and the only object in space, other than Earth, where clear evidence of stable bodies of surface liquid has been found.

The atmosphere of Titan is largely nitrogen; minor components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog. The climate—including wind and rain—creates surface features similar to those of Earth, such as dunes, rivers, lakes, seas (probably of liquid methane and ethane), and deltas, and is dominated by seasonal weather patterns as on Earth. With its liquids (both surface and subsurface) and robust nitrogen atmosphere, Titan's methane cycle is analogous to Earth's water cycle, at the much lower temperature of about 94 K (−179.2 °C; −290.5 °F).

Titan is the sixth gravitationally rounded moon from Saturn. Frequently described as a planet-like moon, Titan is 50% larger than Earth's Moon, and it is 80% more massive. It is the second-largest moon in the Solar System, after Jupiter's moon Ganymede, and is larger than the smallest planet, Mercury, but only 40% as massive. (Source: Wikipedia)
