This spiral galaxy was observed as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) programme, a large project that includes observations from several space- and ground-based telescopes of many galaxies to help researchers study all phases of the star formation cycle, from the formation of stars within dusty gas clouds to the energy released in the process that creates the intricate structures revealed by Webb’s new images.
NGC 7496 is 24 million light-years away in the constellation Grus.
Learn more about what can be seen in this vast collection of Webb images here.
[Image description: The central core of Webb’s image of the galaxy NGC 7496 begins as a bright white dot that melts into bright oranges. Eight prominent diffraction spikes emanate from the centre. A bright orange arc that looks like a thin, backward S forms the bar and two of the face-on spiral galaxy’s arms.]

How methane is created and destroyed on Mars is an important question in understanding the various detections and non-detections of methane at Mars, with differences in both time and location. Although making up a very small amount of the overall atmospheric inventory, methane in particular holds key clues to the planet’s current state of activity.
This graphic depicts some of the possible ways methane might be added or removed from the atmosphere.
One exciting possibility is that methane is generated by microbes. If buried underground, this gas could be stored in lattice-structured ice formations known as clathrates, and released to the atmosphere at a much later time.
Methane can also be generated by reactions between carbon dioxide and hydrogen (which, in turn, can be produced by reaction of water and olivine-rich rocks), by deep magmatic degassing or by thermal degradation of ancient organic matter. Again, this could be stored underground and outgassed through cracks in the surface. Methane can also become trapped in pockets of shallow ice, such as seasonal permafrost.
Ultraviolet radiation can both generate methane – through reactions with other molecules or organic material already on the surface, such as comet dust falling onto Mars – and break it down. Ultraviolet reactions in the upper atmosphere (above 60 km) and oxidation reactions in the lower atmosphere (below 60 km) acts to transform methane into carbon dioxide, hydrogen and water vapour, and leads to a lifetime of the molecule of about 300 years.
Methane can also be quickly distributed around the planet by atmospheric circulation, diluting its signal and making it challenging to identify individual sources. Because of the lifetime of the molecule when considering atmospheric processes, any detections today imply it has been released relatively recently.
But other generation and destruction methods have been proposed which explain more localized detections and also allow a faster removal of methane from the atmosphere, closer to the surface of the planet. Dust is abundant in the lower atmosphere below 10 km and may play a role, along with interactions directly with the surface. For example, one idea is that methane diffuses or ‘seeps’ through the surface in localized regions, and is adsorbed back into the surface regolith. Another idea is that strong winds eroding the planet’s surface allows methane to react quickly with dust grains, removing the signature of methane. Seasonal dust storms and dust devils could also accelerate this process.
Continued exploration at Mars – from orbit and the surface alike – along with laboratory experiments and simulations, will help scientists to better understand the different processes involved in generating and destroying methane.

Expedition 52/53 crew member and ESA astronaut Paulo Nespoli participates in training at NASA's Johnson Space Center in Houston, USA.
In July 2015 Paolo was assigned a third spaceflight as part of Expeditions 52 and 53 to the International Space Station. He will be launched on a Soyuz vehicle in May 2017 on a five-month mission. The latest mission is part of a barter agreement between NASA and Italy’s ASI space agency involving ESA astronauts.

ESA astronaut Alexander Gerst will be launched into space on the Soyuz MS-09 spacecraft alongside NASA astronaut Serena Auñón-Chancellor and Roscosmos commander Sergei Prokopyev from the Baikonur cosmodrome in Kazakhstan on 6 June 2018.
All astronauts that fly on a Soyuz have a final authorisation for launch given by the state commission followed by a last press conference on Earth before liftoff.
This will be Alexander’s second spaceflight, called Horizons. He will also be the second ESA astronaut to take over command of the International Space Station. The Horizons science programme is packed with European research: over 50 experiments will deliver benefits to people on Earth as well as prepare for future space exploration.

Mt Etna captured by ESA astronaut Matthias Maurer aboard the International Space Station. Matthias posted this image to his social media channels on Saturday 12 February with the caption:
"Not a very clean shot since there is way too much humidity in Europe’s air at the moment but astro Luca's home volcano Etna is clearly smoking (and spitting lava as I learnt from the news)"

bonnie is there for me when i need her. i've been keeping my backgrounds simple, as i wanted to represent how the mind can be isolating at times. the splash of color represents the wave of love she brings to me
ESA astronaut Andreas Mogensen, Soyuz spacecraft commander Gennady Padalka and Kazakh cosmonaut Aidyn Aimbetov landed 12 September 2015 at 00:51 GMT (02:51 CEST) in the steppe of Kazakhstan, marking the end of their missions to the International Space Station.
Andreas became Denmark’s first astronaut when he left our planet on 2 September on his 10-day iriss mission. The trio undocked from the orbiting complex on 11 September at 21:29 GMT (23:29 CEST) in an older Soyuz spacecraft, leaving the new vessel they arrived in for the Station crew.
ESA used the mission to test new technologies and conduct a series of scientific experiments.
