New Arctic Lakes Could Soon Be a Major Source of Atmospheric Methane

NASA Goddard | For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of microbes waking up and digesting once-frozen organic materials. 

A new NASA-funded study focuses on a mechanism that could accelerate the release of this atmospheric carbon, the result of thermokarst lakes. These lakes form when thawing permafrost causes the ground to slump, creating a depression that collects rain and snowmelt and perpetuates a cycle of further permafrost thaw.

Painting a picture of the evolving Universe | Hubble

The Hubble Deep Field from 1995 allowed astronomers a first glimpse into the early Universe. This first picture was followed later by an even deeper observation, the Hubble Ultra Deep Field in 2004. Both images were observed in visible light, the same form of light human eyes can see. But astronomers are also interested in the many forms of invisible light out in the Universe. Therefore, the Ultra Deep Field was later observed in the infrared and the ultraviolet as well, allowing scientists to learn even more about the Universe and to look back even further into its history.

It is less known that the famous deep field observations were not the only images the NASA/ESA Hubble Space Telescope took of the distant Universe. Hubble is also an essential part of the GOODS (The Great Observatories Origins Deep Survey) programme, which unites extremely deep observations from several space telescopes: NASA’s Spitzer and Chandra; ESA's Herschel and XMM-Newton; and Hubble.

Together these observatories observe two patches of the sky, the GOODS North and the GOODS South fields, with the aim of studying it in as many different wavelengths as possible. The new image here shows part of the GOODS North Field; it includes new Hubble data at ultraviolet wavelengths in addition to the existing data. Because Earth’s atmosphere filters out most ultraviolet light, these observations can only be accomplished from space.

The observation program, called the Hubble Deep UV (HDUV) Legacy Survey, 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.

Under the celestial arch | ESO

In this spectacular image, taken by ESO Photo Ambassador Petr Horálek, we see the bright arc of the Milky Way stretching across the sky above ESO’s La Silla Observatory in Chile. On the ground are the dome of ESO’s 3.6-meter optical telescope (on the right) and the silvery dish of the Swedish-ESO submillimeter telescope (on the left). Even though it was decommissioned in 2003 to make way for the more advanced APEX and ALMA instruments, the Swedish-ESO dish still seems to be gazing longingly at the sky, perhaps hoping for another chance to explore the mysteries of the heavens.

The Milky Way dominates this image, showing clearly why La Silla is one of the best astronomical sites in the world, famed for its dark skies and clear air. From the peak of the bright arc hangs a striking red feature known as Gum Nebula. This, like similar regions along the band of the Milky Way, is an emission nebula, where gas is made to glow by radiation emitted from nearby bright stars. The bright band of the Milky Way is broken up by dark filaments of dust, wherein stars are forming, stars that will add to the spectacle in the millennia to come.

Sitting under the arc is one of the Milky Way’s companion dwarf galaxies, the Large Magellanic Cloud; below it, just to the right of the Swedish-ESO dish, is the second such companion, known unsurprisingly as the Small Magellanic Cloud. Over to the right of the image is the planet Jupiter, glowing brightly against the faint glow of the gegenschein, a phenomenon only seen in the darkest skies. A rare sight for most, this magical celestial display is commonplace at astronomical observing sites like La Silla.

Sunrise over Gulf of Saint Lawrence


An astronaut aboard the International Space Station (ISS) focused a camera lens on the Sun’s reflection point, roughly 1700 kilometers (1050 miles) to the northeast of the spacecraft’s position over Massachusetts at the time this image was taken. This oblique photograph shows the horizon and coastline of the Canadian provinces of Newfoundland and Labrador, with Quebec further inland. 

There was only a narrow window of opportunity for this sunglint photograph. The Sun’s reflection was moving across the narrows (separating the island of Newfoundland and mainland Labrador) and in a break between two cloud banks. Clouds are so common in this part of the world that images of the region are not often acquired from the ISS.

The Gulf of Saint Lawrence is the outlet of the North American Great Lakes via the Saint Lawrence River into the Atlantic Ocean. The Strait of Belle Isle is a waterway in eastern Canada that separates the Labrador Peninsula from the island of Newfoundland, in the province of Newfoundland and Labrador.

From their altitude in the space station, the astronauts were seeing an early sunrise, which was timed at 4:41 a.m. at Goose Bay in Labrador on the day this photograph was taken. The Sun would only rise at 5:20 a.m. for people on the ground in Massachusetts directly below the spacecraft.

Three airplane condensation trails appear in the left half of the image, and another is visible on the right margin. All of them are oriented along the shortest air route to Europe (over eastern Canada), which is one of the most densely travelled air routes between North America and Europe.

Astronaut photograph ISS056-E-77502 was acquired on July 5, 2018, with a Nikon D4 digital camera using a 145 millimeter lens and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 56 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public.

Earth Aurora | International Space Station

Cosmonaut Oleg Artemyev: "Is there nothing more beautiful than to view the Aurora from the height of the International Space Station?"

Auroras are produced when the Earth's magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity.

Continents and Clouds | International Space Station

This time-lapse video was taken by the Expedition 56 crew on board the International Space Station. The sequence of shots were taken using a 16mm fisheye camera lens on June 21, 2018 from 15:19:25 to 16:09:25 GMT, on a day pass from The Pacific Ocean to Africa. The video begins over cloud covered waters of the Pacific Ocean and heads toward the western coast of North America. The first sight of land is the Baja peninsula of Mexico and quickly approaches the southwest US states of Arizona and Utah. The US midwest is mostly cloudy. Orange waters on the western edge of Lake Superior are the result of significant flooding in Duluth, MN at the time of the video. The ISS continues over the northern Atlantic Ocean and passes over Spain at the Strait of Gibraltar. As the ISS heads southeast across Africa, orange Saharan sands come into view and the video ends with a sunset over the cloud covered continent.

NASA Honors Aretha Franklin

Asteroid Named for The Queen of Soul
NASA Statement: "We’re saddened by the loss of Aretha Franklin (1942-2018). Asteroid 249516 Aretha, found by our NEOWISE mission and named after the singer to commemorate the Queen of Soul, will keep orbiting beyond Mars."

The Principal Investigator for NEOWISE is Amy Mainzer of the Jet Propulsion Laboratory (JPL). JPL manages NEOWISE for NASA's Science Mission Directorate, and carries out mission operations. The Space Dynamics Laboratory, Utah State University provided the science instrument. Ball Aerospace and Technologies Corp. built the spacecraft. Science operations, data processing and archiving take place at the Infrared Processing and Analysis Center at the California Institute of Technology.

NEOWISE: The Wide-field Infrared Survey Explorer (WISE) is a NASA infrared-wavelength astronomical space telescope active from December 2009 to February 2011. It was launched on December 14, 2009, and decommissioned/hibernated on February 17, 2011 when its transmitter was turned off. It performed an all-sky astronomical survey with images in 3.4, 4.6, 12 and 22 μm wavelength range bands, over 10 months using a 40 cm (16 in) diameter infrared telescope in Earth-orbit. The initial mission length was limited by its hydrogen coolant, but a secondary post-cryogenic mission continued four more months with two of the four detectors remaining operational.

The NEOWISE project has delivered physical data on an enormous number of minor planets and efforts are underway to mine even more out of the dataset. To date, the project has resulted in the detection of ~158,000 asteroids at thermal infrared wavelengths, including ~700 NEOs, and has discovered ~34,000 new asteroids, 135 of which are NEOs. The project has detected more than 155 comets, including 21 discoveries. Preliminary physical properties such as diameter and visible albedo have been computed and published for nearly all of these objects to date, enabling a range of studies of the origins and evolution of the small bodies in our solar system. So far, NEOWISE data have been used to constrain the numbers, sizes, and orbital elements of NEOs, including potentially hazardous asteroids, as well as the Jovian Trojans, Hilda-group asteroids, and the physical properties and collisional history of Main Belt asteroid families. Efforts were undertaken to perform detailed analysis of the small body thermophysical properties, as well as the dust and gas properties of active bodies. Nucleus sizes have been computed for nearly the entire NEOWISE cometary sample to date in order to apply debiasing techniques to extrapolate the sample to the population writ large.
