NASA image release September 25, 2012  Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.  Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon.  The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.  The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see.  To read more go to:http://www.nasa.gov/mission_pages/hubble/science/xdf.html  Credit: NASA; ESA; G.

The unit was an Apollo Telescope Mount (ATM) instrument designed to sequentially photograph the solar chromosphere and corona in selected ultraviolet wavelengths. The instrument also obtained information about composition, temperature, energy conversion and transfer, and plasma processes of the chromosphere and lower corona. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

Phil Neudeck- Can Take the Heat      When it comes to the heat of extreme environments like Venus, electronics can get fried within a few minutes of arrival.  But NASA Researcher Phil Neudeck and his team have developed extremely durable silicon carbide semiconductor integrated circuits to survive those harsh conditions. After successfully testing the electronics in our high-pressure, high-temperature extreme environments chamber, there is now a path forward for Venus landers to survive and operate scientific experiments on the planet’s surface for longer durations.

This STS-80 onboard photograph shows the Orbiting Retrievable Far and Extreme Ultraviolet Spectrometer-Shuttle Pallet Satellite II (ORFEUS-SPAS II), photographed during approach by the Space Shuttle Orbiter Columbia for retrieval. Built by the German Space Agency, DARA, the ORFEUS-SPAS II, a free-flying satellite, was dedicated to astronomical observations at very short wavelengths to: investigate the nature of hot stellar atmospheres, investigate the cooling mechanisms of white dwarf stars, determine the nature of accretion disks around collapsed stars, investigate supernova remnants, and investigate the interstellar medium and potential star-forming regions. Some 422 observations of almost 150 astronomical objects were completed, including the Moon, nearby stars, distant Milky Way stars, stars in other galaxies, active galaxies, and quasar 3C273. The STS-80 mission was launched November 19, 1996.

This profile perspective of an active region revealed above it (June 24-25, 2018). Charged particles spinning along these field lines are illuminated in this wavelength of extreme ultraviolet light. The little Earth superimposed on the image and videos gives one a sense of just how humongous these loops really are. Our eyes cannot see extreme ultraviolet light, but our instruments can. The images are colorized to distinguish between these from images taken in other wavelengths by SDO. Note there is another, smaller active region on the left side of the image.

This graphic illustrates how a faraway quasar (an extremely bright region in the center of some distant galaxies) is altered by a massive foreground galaxy. The galaxy's powerful gravity warps and magnifies the quasar's light, producing four distorted images of the quasar.  Dark matter is an invisible substance that makes up the bulk of the universe's mass and creates the scaffolding upon which galaxies are built.  Quadruple images of a quasar rare because the background quasar and foreground galaxy require an almost perfect alignment.  https://photojournal.jpl.nasa.gov/catalog/PIA23641

NASA's Solar Dynamics Observatory observes the Sun in ten different wavelengths because each wavelength reveals different solar features. Here, we have selected two images taken at virtually the same time but in different wavelengths of extreme ultraviolet light. The red tinted image, which captures material not far above the Sun's surface, is especially good for revealing details along the edge of the Sun, like the small prominence at the ten o'clock position. The brown tinted image clearly shows two large coronal holes (darker areas) as well as some faint magnetic field lines and hints of solar activity (lighter areas), neither of which are apparent in the red image. This activity is occurring somewhat higher in the Sun's corona. In a way it is like peeling away the layers of an onion, a little at a time. Animations are available at https://photojournal.jpl.nasa.gov/catalog/PIA22724
