In space, being outshone is an occupational hazard. This NASA/ESA Hubble Space Telescope image captures a galaxy named NGC 7250. Despite being remarkable in its own right — it has bright bursts of star formation and recorded supernova explosions — it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it. This bright object is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard), much closer than the much more distant galaxy. Only this way a normal star can outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study. In this case TYC 3203-450-1 million times closer than NGC 7250 which lies over 45 million light-years away from us. Would the star be the same distance as NGC 7250, it would hardly be visible in this image.

This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colourful region surrounding the Herbig-Haro object HH 505. Herbig-Haro objects are luminous regions surrounding newborn stars, and are formed when ionised jets of gas spewing from these newborn stars collide with nearby gas and dust at high speeds. In the case of HH 505, these jets originate from the star IX Ori, which lies on the outskirts of the Orion Nebula around 1000 light-years from Earth. The jets themselves are visible as gracefully curving structures at the top and bottom of this image, and are distorted into sinuous curves by their interaction with the large-scale flow of gas and dust from the core of the Orion Nebula. This observation was captured with Hubble’s Advanced Camera for Surveys (ACS) by astronomers studying the properties of outflows and protoplanetary discs. The Orion Nebula is awash in intense ultraviolet radiation from bright young stars. Stellar jets are irradiated while they collide with the surrounding gas and dust, lighting them up for Hubble to see. This allows astronomers to directly observe jets and outflows and learn more about their structures. The Orion Nebula is a dynamic region of dust and gas where thousands of stars are forming, and is the closest region of massive star formation to Earth. As a result, it is one of the most scrutinised areas of the night sky and has often been a target for Hubble. This observation was also part of a spellbinding Hubble mosaic of the Orion Nebula, which combined 520 ACS images in five different colours to create the sharpest view ever taken of the region.
This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505.

As the coronavirus pandemic slowed global commerce to a crawl in early 2020, emissions of nitrogen oxides (NOx) – which create ozone, a danger to human health and to climate – decreased 15% globally with local reductions as high as 50%, according to a study led by scientists at NASA’s Jet Propulsion Laboratory. As a result of the lower NOx emissions, by June 2020 global ozone levels had dropped to a level that policymakers thought it would take at least 15 years to reach by conventional means, such as regulations.

In 2018, Hawaii’s Kilauea volcano experienced its largest eruption in over 200 years. JPL scientists used data from the rare event to better understand what causes large-scale eruptions like this. The culprit? The collapse of a volcano’s caldera – the large, crater-like depression at the volcano’s summit. Kilauea is one of the most active volcanoes in the world. Because of this and its relative ease of accessibility, it is also among the most heavily outfitted with monitoring equipment – instruments that measure and record everything from earthquakes and ground movement to lava volume and advancement.

Study Identifies Methane ‘Super-Emitters’ in Largest US Oilfield

Fixing just the worst leaks in the Permian Basin oilfield’s infrastructure could cut methane emissions by 55 tons an hour, according to a study by NASA, University of Arizona, and ASU.
About half of the biggest sources of the potent greenhouse gas methane in the Permian Basin oilfield are likely to be malfunctioning oilfield equipment, according to a month-long airborne study by NASA’s Jet Propulsion Laboratory, the University of Arizona, and Arizona State University.
Repeatedly measuring the size and persistence of emission sources using sensor-equipped aircraft, researchers found that repairing only the 123 sources that they found leaking most persistently on their flights would reduce methane emissions by 55 tons (50 metric tons) an hour. That’s equivalent to 5.5% of the U.S. Environmental Protection Agency’s estimates of all methane emissions from oil and gas production in the entire United States.
The research team measured methane concentrations around “super-emitter” methane sources – those emitting more than 22 pounds (10 kilograms) of methane per hour – in the oilfield, which is located in Texas and New Mexico. They calculated the emission rates by combining observed methane concentrations with reported wind speeds. Using airborne imaging spectrometers that identify methane and other gases by their effects on reflected sunlight, the campaign located a total of 1,756 super-emitters in a 22,000-square-mile (57,000-square-kilometer) section of the immense oilfield. As they resurveyed the area throughout the month, the team recorded emissions each time a plume was visible, whether once or a dozen times.
“Multiple revisits of these sites are the best way to discriminate between unplanned and planned emissions,” said Daniel Cusworth, a JPL scientist and lead author of an analysis published today in the journal Environmental Science and Technology. Cusworth explained that while some regular operations in an oilfield, such as venting pressure-relief valves, release methane, plumes from these planned operations would probably be visible on only one or two consecutive flights. If an emission plume persists, by far the most likely cause is malfunctioning or broken oil and gas equipment. There’s no other industry in the region that could produce such large plumes, and there are more than 60,000 oil and gas wells as well as compressors, pipelines, and other types of equipment – all of which can potentially leak.
For their analysis, Cusworth and colleagues focused on 1,100 sources seen emitting methane plumes on at least three flights. Just 123 of these were classified as most persistent, with plumes visible on 50 to 100% of revisits. These few sources emitted about 29% of all the methane detected from the entire group. The 258 plumes in the next most persistent class produced an additional 23% of detected emissions; the researchers think these sources are leaks or a mixture of leaks and planned operations. They classified the remaining two-thirds of the sources as least persistent and most likely to be the result of planned operations. This last and largest class produced 48% of emissions.
Once methane sources have been located and verified on the ground by facility operators, there’s a good chance that leaks can be repaired, said Riley Duren of the University of Arizona, who designed and led the flight campaign. “We’ve done cooperative studies with oil and gas operators in California and the Permian where they independently report that 50% of the sources we’re finding are fixable.”
The campaign also recorded surprisingly large variations in the extent of emissions. In one part of the basin, emissions almost doubled over a five-day period and then dropped back almost to the original value over another 10 days. These large, unpredictable variations prove that a single snapshot of methane emissions from any location is inadequate for decision-makers to monitor and regulate emission sources, Duren said. “You need measurements daily or weekly,” he added. “That’s a big argument for using airborne and satellite remote sensing.”
The imaging spectrometers used in the study, NASA’s Next-Generation Airborne Visible/Infrared Imaging Spectrometer and ASU’s Global Airborne Observatory, are able to pinpoint methane sources to within about 15 to 30 feet (5 to 10 meters) while flying at the altitude of a commercial airliner. When methane emission plumes were detected, researchers used a high-resolution camera to relate the plumes to individual pieces of equipment on the ground.
