Jupiter's Swirling Cloudscape | NASA Juno

Intricate swirls in Jupiter's volatile northern hemisphere are captured in this color-enhanced image from NASA's Juno spacecraft. Bursts of bright-white "pop-up" clouds appear scattered throughout the scene, with some visibly casting shadows on the neighboring cloud layers beneath them. Juno scientists are using shadows to determine the distances between cloud layers in Jupiter's atmosphere, which provide clues to their composition and origin.

This image was taken at 10:27 p.m. PDT on May 23, 2018 (1:27 a.m. EDT on May 24) as the spacecraft performed its 13th close flyby of Jupiter. At the time, Juno was about 7,050 miles (11,350 kilometers) from the planet's cloud tops, above a northern latitude of approximately 49 degrees.

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

JunoCam's raw images are available at www.missionjuno.swri.edu/junocam for the public to peruse and process into image products.

Energetic lightshow at Saturn’s north pole | Hubble

August 30, 2018: Astronomers using the NASA/ESA Hubble Space telescope have taken a series of spectacular images featuring the fluttering auroras at the north pole of Saturn. The observations were taken in ultraviolet light and the resulting images provide astronomers with the most comprehensive picture so far of Saturn’s northern aurora.

In 2017, over a period of seven months, the NASA/ESA Hubble Space Telescope took images of auroras above Saturn’s north pole region using the Space Telescope Imaging Spectrograph. The observations were taken before and after the Saturnian northern summer solstice. These conditions provided the best achievable viewing of the northern auroral region for Hubble.

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere —the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth [1].

However, these auroras are not unique to Earth. Other planets in our Solar System have been found to have similar auroras. Among them are the four gas giants Jupiter, Saturn, Uranus and Neptune. Because the atmosphere of each of the four outer planets in the Solar System is—unlike the Earth—dominated by hydrogen, Saturn’s auroras can only be seen in ultraviolet wavelengths; a part of the electromagnetic spectrum which can only be studied from space.

Hubble allowed researchers to monitor the behaviour of the auroras at Saturn's north pole over an extended period of time. The Hubble observations were coordinated with the “Grand Finale” of the Cassini spacecraft, when the spacecraft simultaneously probed the auroral regions of Saturn [2]. The Hubble data allowed astronomers to learn more about Saturn’s magnetosphere, which is the largest of any planet in the Solar System other than Jupiter.

The images show a rich variety of emissions with highly variable localized features. The variability of the auroras is influenced by both the solar wind and the rapid rotation of Saturn, which lasts only about 11 hours. On top of this, the northern aurora displays two distinct peaks in brightness—at dawn and just before midnight. The latter peak, unreported before, seems specific to the interaction of the solar wind with the magnetosphere at Saturn’s solstice.

The main image presented here is a composite of observations made of Saturn in early 2018 in the optical and of the auroras on Saturn’s north pole region, made in 2017, demonstrating the size of the auroras along with the beautiful colors of Saturn.

Hubble has studied Saturn's auroras in the past. In 2004, it studied the southern auroras shortly after the southern solstice and in 2009 it took advantage of a rare opportunity to record Saturn when its rings were edge-on. This allowed Hubble to observe both poles and their auroras simultaneously.

Notes
[1] The auroras here on Earth have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

[2] Cassini was a collaboration between NASA, ESA and the Italian Space Agency. It spent 13 years orbiting Saturn, gathering information and giving astronomers a great insight into the inner workings of Saturn. Cassini took more risks at the end of its mission, travelling through the gap between Saturn and its rings. No spacecraft had previously done this, and Cassini gathered spectacular images of Saturn as well as new data for scientists to work with. On September 15, 2017 Cassini was sent on a controlled crash into Saturn.

The Hubble Space Telescope is a project of international cooperation between ESA and NASA.

Andes Mountain Range | International Space Station

Two docked Russian spacecraft on the International Space Station, the Soyuz MS-09 crew ship and the Progress 70 resupply ship, were pictured as the orbital complex flew 253 miles above the Andes mountain range and the South American continent.

The Andes or Andean Mountains are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. This range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina. (Source: Wikipedia)

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!
