Global average carbon dioxide concentrations as seen by NASA’s Orbiting Carbon Observatory-2 mission, June 1-15, 2015. OCO-2 measures carbon dioxide from the top of Earth's atmosphere to its surface. Higher carbon dioxide concentrations are in red, with lower concentrations in yellows and greens. Scientists poring over data from OCO-2 mission are seeing patterns emerge as they seek answers to questions about atmospheric carbon dioxide.  Among the most striking features visible in the first year of OCO-2 data is the increase in carbon dioxide in the northern hemisphere during winter, when trees are not removing carbon dioxide, followed by its decrease in spring, as trees start to grow and remove carbon dioxide from the atmosphere.  http://photojournal.jpl.nasa.gov/catalog/PIA20039
NASA Carbon Sleuth Begins Year Two
NASA's ARIA team, in collaboration with the Earth Observatory of Singapore, used satellite data to map the extent of likely damage following a massive explosion in Beirut. Dark red pixels represent the most severe damage. Areas in orange are moderately damaged, and areas in yellow are likely to have sustained somewhat less damage. Each colored pixel represents an area of 30 meters (33 yards).  https://photojournal.jpl.nasa.gov/catalog/PIA23692
ARIA Damage Map: Beirut Explosion Aftermath
On Sept. 16, 2015, a magnitude 8.3 earthquake struck near the coast of central Chile along the boundary of the Nazca and South American tectonic plates. Dubbed the Illapel earthquake, the shaking lasted at least three minutes and propelled a 15-foot (4.5-meter) tsunami that washed into Coquimbo and other coastal areas. Smaller tsunami waves raced across the Pacific and showed up on the shores of Hawaii and other islands. The earthquake and tsunami caused substantial damage in several Chilean coastal towns, and at least 13 deaths have been reported. Demanding building codes and extensive disaster preparedness helped to limit the loss of life and property.  The maps above, known as interferograms, show how the quake moved the ground, as observed by the Copernicus Sentinel-1A satellite (operated by the European Space Agency) and reported by ground stations to the U.S. Geological Survey. Sentinel-1A carries a synthetic aperture radar (SAR) instrument, which beams radio signals toward the ground and measures the reflections to determine the distance between the ground and the satellite. By comparing measurements made on Aug. 24 and Sept. 17, Cunren Liang, Eric Fielding, and other researchers from NASA's Jet Propulsion Laboratory were able to determine how the land surface shifted during and after the earthquake.  Interferograms can be used to estimate where the fault moved deep in Earth and which areas have increased stress and higher likelihood of future earthquakes. The details can also provide important information to better understand the earthquake process.  On both the close-up and the broad-view maps, the amount of land motion is represented in shades from yellow to purple. Areas where the ground shifted the most (vertically, horizontally, or both) are represented in yellow, while areas with little change are represented in purple. Circles show the location of earthquakes and aftershocks in the two days after the initial 8.3 earthquake, as reported by the USGS National Earthquake Information Center. Larger quakes are represented by larger circles. The base map layer uses a digital elevation model and a bathymetry map to show the contours of the land surface and seafloor.  The interferograms above show that land moved as much as 1.4 meters toward to satellite (generally in the vertical direction) near the coast, and early estimates of the horizontal motion suggest it was as much as 2 meters. While SAR can see through clouds and the dark of night, it cannot see much through water. It is likely that much of the ground deformation from the earthquake occurred underwater, which explains the formation of the tsunami and the location of many aftershocks.  http://photojournal.jpl.nasa.gov/catalog/PIA20002

These radar images of near-Earth asteroid 3200 Phaethon were generated by astronomers at the National Science Foundation's Arecibo Observatory on Dec. 17, 2017. Observations of Phaethon were conducted at Arecibo from Dec.15 through 19, 2017. At time of closest approach on Dec. 16 at 3 p.m. PST (6 p.m. EST, 11 p.m. UTC) the asteroid was about 6.4 million miles (10.3 million kilometers) away, or about 27 times the distance from Earth to the moon. The encounter is the closest the object will come to Earth until 2093.   An animation is available at https://photojournal.jpl.nasa.gov/catalog/PIA22185

This animation shows the accumulation of five adjoining swaths of data over the Los Angeles metropolitan area that when combined, create a map of carbon dioxide (CO2) concentrations that covers about 50 square miles (80 square kilometers). Researchers have used the data, collected by NASA's Orbiting Carbon Observatory 3 (OCO-3) instrument aboard the space station, to create one of the most accurate maps ever made from space of the human influence on CO2 abundances in the L.A. Basin  Each pixel is about 1.3 miles (2.2 kilometers); the color indicates how much higher the concentration of CO2 is in that spot than in clean desert air north of the city (measured at NASA's Armstrong Research Center, upper right). The highest CO2 readings, in yellow on the map, are on the west side of downtown L.A. – a densely populated area with congested freeways and CO2-emitting industries. Yellow indicates atmospheric CO2 elevated by five or more molecules out of every million molecules of air, or five parts per million. That's equivalent to the amount that global atmospheric CO2 is rising globally on average every two years  Most of the increasing CO2 in the global atmosphere comes from humans burning fossil fuels for energy, and 70% of that comes from cities. Los Angeles has set goals for cutting its carbon emissions. This type of data can help decisionmakers choose the most effective policies to reach those goals and to measure the effectiveness of new regulations. Data from ground level provides critical local measurements, but satellite data is equally necessary because it covers a wider area and also measure CO2 throughout the entire depth of the atmosphere.

Image shows OCO-3's first preliminary solar-induced fluorescence (SIF) measurements over western Asia. Solar-induced fluorescence is the glow plants emit from photosynthesis — the process of plant growth that includes the capture of carbon from the atmosphere. Areas with lower photosynthesis activity are in shown in light green; areas with higher photosynthesis activity are shown in dark green.  As expected, there is significant contrast in plant activity from areas of low vegetation near the Caspian Sea to areas of more dense vegetation like the forests and farms north and east of the Mingachevir Reservoir (near the center of the image).  The mission team expects to complete OCO-3's In-orbit checkout phase — the period where they ensure all instruments and components are working and calibrated correctly — in August 2019. They are scheduled to release official CO2 and solar-induced fluorescence data to the science community a year later; however, the data will likely be available sooner given the quality of the measurements that OCO-3 is already making.  https://photojournal.jpl.nasa.gov/catalog/PIA23353

This image shows CO2 over the United States during OCO-3's first few days of science data collection. These initial measurements are consistent with measurements taken by OCO-3's older sibling, OCO-2, over the same area — meaning that even though OCO-3's instrument calibration is not yet complete, it is right on track to continue its (currently still operational) predecessor's data record.  The mission team expects to complete OCO-3's in-orbit checkout phase — the period where they ensure all instruments and components are working and calibrated correctly — in August 2019.

An eruption from the surface of the sun is conspicuous in the lower left portion of this July 6, 2015, image from NASA's Earth-orbiting Solar Dynamics Observatory (SDO). It originates from a location on the surface where NASA's Curiosity Mars rover had been tracking a sunspot in late June and early July.  This image was taken by the Atmosphere Imaging Assembly on SDO using the instrument's 131-Angstrom wavelength channel, which is sensitive to hot solar flares.  The sun completes a rotation about once a month -- faster near its equator than near its poles. This summer, Mars has a view of the opposite side of the sun from what's facing Earth. Images from Curiosity tracking a southern-hemisphere sunspot until it rotated out of view during the July 4 weekend are in an animation at PIA19801. This location on the sun rotated into position to be seen from Earth a few days later.  The eruption visible in this image was linked to a coronal mass ejection observed by SDO and NASA's Solar and Heliospheric Observatory. The coronal mass ejection affected interplanetary space weather, as shown at http://go.nasa.gov/1JSXLF3.  http://photojournal.jpl.nasa.gov/catalog/PIA19680
Solar Activity Seen at Sunspot Site Tracked by Mars Rover
NASA's Solar Dynamics Observatory (SDO) saw both the Moon (upper right) and the Earth (upper left) partially block the sun (Sept. 1, 2016 at 7:33 UT). Just before this image was taken, the Earth totally blocked the sun for a while. SDO orbits 22,000 miles above the Earth in a highly elliptical orbit that sometimes puts the Moon or Earth in front of the sun. The sun image was taken in a wavelength of extreme ultraviolet light. Only once before have both been there at the same time. Note that the edge of the moon is quite crisp because it has no atmosphere.  Movies are available at the Photojournal.  http://photojournal.jpl.nasa.gov/catalog/PIA21028
Double Eclipse
Several times a day for a few days the Earth completely blocked the Sun for about an hour due to NASA's Solar Dynamics Observatory's orbital path (Feb. 15, 2017). The edge of the Earth is not crisp, but kind of fuzzy due to Earth's atmosphere. This frame from a video shows the ending of one such eclipse over -- just seven minutes. The sun is shown in a wavelength of extreme ultraviolet light. These eclipses re-occur about every six months. The Moon blocks SDO's view of the sun on occasion as well.  Movies are available at http://photojournal.jpl.nasa.gov/catalog/PIA21461
Earth Eclipses the Sun
On the 8th anniversary of its launch in 2010, NASA's Solar Dynamics Observatory (SDO) captured a total solar eclipse (Feb. 11, 2018) when Earth crossed in front of the sun. It lasted just 31 minutes. This cosmic event was not visible from Earth. Due to its geosynchronous orbit, there is a three-week period that occurs twice a year during which Earth briefly blocks SDO's view of the sun. The video clip, which shows the sun in a wavelength of extreme ultraviolet light, covers about an hour and a half near the time of the eclipse.   The video can be viewed at https://photojournal.jpl.nasa.gov/catalog/PIA22259

The crater in the center of this HiRISE image defines where zero longitude is on Mars, like the Greenwich Observatory does for the Earth.  Originally, the larger crater that this crater sits within, called Airy Crater, defined zero longitude for the Red Planet. But as higher resolution images became available, a smaller feature was needed. This crater, called Airy-0 (zero), was selected because it would require no adjustment of existing maps.  These days, longitude on Mars is measured even more precisely using radio tracking of landers such as InSight, but everything is still defined to keep zero longitude centered on this crater.  https://photojournal.jpl.nasa.gov/catalog/PIA25090

These first radar images of 2015 TB145 from the National Science Foundation 1,000-foot 305-meter Arecibo Observatory in Puerto Rico, indicate the near-Earth object is spherical in shape and approximately 2,000 feet 600 meters in diameter. The radar images were taken on Oct. 30, 2015, and the image resolution is 25 feet (7.5 meters) per pixel.  The celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun.   http://photojournal.jpl.nasa.gov/catalog/PIA20040

This still image from an animation from NASA GSFC Solar Dynamics Observatory shows a single plume of plasma, many times taller than the diameter of Earth, spewing streams of particles for over two days Aug. 17-19, 2015 before breaking apart. At times, its shape resembled the Eiffel Tower. Other lesser plumes and streams of particles can be seen dancing above the solar surface as well. The action was observed in a wavelength of extreme ultraviolet light.  http://photojournal.jpl.nasa.gov/catalog/PIA19875

Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This multi-wavelength image shows this galaxy cluster, called IDCS J1426.5+3508 (IDCS 1426 for short), in X-rays recorded by the Chandra X-ray Observatory in blue, visible light observed by the Hubble Space Telescope in green, and infrared light detected by the Spitzer Space Telescope in red.  This rare galaxy cluster, which is located 10 billion light-years from Earth, is almost as massive as 500 trillion suns. This object has important implications for understanding how such megastructures formed and evolved early in the universe. The light astronomers observed from IDCS 1426 began its journey to Earth when the universe was less than a third of its current age. It is the most massive galaxy cluster detected at such an early time.  First discovered by the Spitzer Space Telescope in 2012, IDCS 1426 was then observed using the Hubble Space Telescope and the Keck Observatory to determine its distance. Observations from the Combined Array for Millimeter-wave Astronomy indicated it was extremely massive. New data from the Chandra X-ray Observatory confirm the galaxy cluster's mass and show that about 90 percent of this mass is in the form of dark matter -- the mysterious substance that has so far been detected only through its gravitational pull on normal matter composed of atoms. http://photojournal.jpl.nasa.gov/catalog/PIA20063
