Saturn: Shadow Art | NASA Cassini Mission
Assembled using RGB filtered images of Saturn taken on November 7, 2004.
The Cassini mission was a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

NASA X-plane Preliminary Design Model Tests Quiet Supersonic Technology
Image: Engineer stands with X-plane design model in wind tunnel
Samantha O’Flaherty, Test Engineer for Jacobs Technology Inc., finalizes the set-up of the Quiet Supersonic Technology (QueSST) Preliminary Design Model inside the 14- by- 22 Foot Subsonic Tunnel at NASA Langley Research Center. Over the next several weeks, engineers will conduct aerodynamic tests on the 15% scale model and the data collected from the wind tunnel test will be used to predict how the vehicle will perform and fly in low-speed flight.
The QueSST Preliminary Design is the initial design stage of NASA’s planned Low-Boom Flight Demonstration experimental airplane, otherwise known as an X-plane. This future X-plane is one of a series of X-planes envisioned in NASA’s New Aviation Horizons initiative, which aims to reduce fuel use, emissions and noise through innovations in aircraft design that depart from the conventional tube-and-wing aircraft shape.

Hurricane Maria Makes Landfall in Puerto Rico | NOAA
This GOES-16 geocolor image was captured as Category 4 Hurricane Maria made landfall near Yabucoa, Puerto Rico, around 6:15 a.m. EDT on September 20, 2017.
Maria knocked out radar on the island just before Maria made landfall. With this critical technology disabled and a major hurricane approaching, forecasters were able to utilize data from NOAA’s latest geostationary satellite, GOES-16, to track the storm in real-time.

Hurricane Maria | NASA-NOAA Suomi NPP Satellite
Sept. 20, 2017: NASA-NOAA’s Suomi NPP satellite VIIRS instrument captured this thermal image on Sept. 20, 2017, at 2:12 a.m. EDT (0612 UTC). At the time, Maria’s eye was just east of the American Virgin Islands, and its northwestern quadrant stretched over Puerto Rico.
NASA looked into Hurricane Maria and found that powerful convective storms within the hurricane were dropping heavy rainfall. Maria brought that heavy rainfall to Puerto Rico and made landfall on Sept. 20 at 6:15 a.m. EDT. NASA-NOAA’s Suomi NPP satellite VIIRS instrument captured a thermal image on Sept. 20 at 2:12 a.m. EDT (0612 UTC). The image showed very cold cloud top temperatures in the powerful thunderstorms in Maria’s eyewall. At the time, Maria’s eye was just east of the American Virgin Islands, and its northwestern quadrant stretched over Puerto Rico.

Hurricane Maria | International Space Station
Sept. 19, 2017: External cameras on the International Space Station captured dramatic views of Hurricane Maria as it churned through the Caribbean Sept. 19 as a potentially catastrophic category 5 hurricane, with maximum sustained winds of 165 MPH. Maria is forecast to pass near or over the U. S. Virgin Islands and Puerto Rico tonight and Wednesday.

NTT and beyond
Located at ESO's La Silla Observatory in the Chilean Atacama Desert, the NTT was inaugurated in 1989. It was the first ever telescope to have a computer-controlled main mirror. This 3.58-meter mirror is very flexible and its shape can be continuously changed, allowing astronomers to counteract deformations due to external influences such as wind, temperature and mechanical stress mid-observation in order to see the objects as clearly as possible.
Complementing the NTT’s groundbreaking technology is the innovative design of its housing. Its octagonal dome is relatively small and includes a series of flaps that ventilate the structure with reduced turbulence, allowing air to flow smoothly across the mirror. The dome walls can be opened entirely—as opposed to only opening the roof, as with conventional domes—to reveal large swathes of the southern sky.
This image was taken by ESO Photo Ambassador Babak Tafreshi.

Spiral Galaxy NGC 6753 | Hubble
Despite the advances made in past decades, the process of galaxy formation remains an open question in astronomy. Various theories have been suggested, but since galaxies come in all shapes and sizes—including elliptical, spiral, and irregular—no single theory has so far been able to satisfactorily explain the origins of all the galaxies we see throughout the Universe.
To determine which formation model is correct (if any), astronomers hunt for the telltale signs of various physical processes. One example of this is galactic coronas, which are huge, invisible regions of hot gas that surround a galaxy’s visible bulk, forming a spheroidal shape. They are so hot that they can be detected by their X-ray emission, far beyond the optical radius of the galaxy. Because they are so wispy, these coronas are extremely difficult to detect. In 2013, astronomers highlighted NGC 6753, imaged here by the NASA/ESA Hubble Space Telescope, as one of only two known spiral galaxies that were both massive enough and close enough to permit detailed observations of their coronas. Of course, NGC 6753 is only close in astronomical terms—the galaxy is nearly 150 million light-years from Earth.
NGC 6753 is a whirl of color in this image—the bursts of blue throughout the spiral arms are regions filled with young stars glowing brightly in ultraviolet light, while redder areas are filled with older stars emitting in the cooler near-infrared.

Cassini Spacecraft's Final Image of Saturn | NASA
This natural color view, created using images taken with red, green and blue spectral filters, was provided by the Cassini spacecraft before the mission concluded on September 15, 2017. The view was acquired on September 14 at 19:59 GMT (spacecraft event time) with the spacecraft's wide-angle camera at a distance of 634,000 km from Saturn.
The Cassini–Huygens mission is a cooperative project of NASA, ESA and the Italian Space Agency.

Ocean Moon Enceladus Setting Behind Saturn | NASA Cassini Mission
It was taken using Cassini's narrow-angle camera at a distance of 1.3 million km from Enceladus and about 1 million km from Saturn. Image scale on Enceladus is 8 km/per pixel. Images taken using red, green and blue spectral filters were assembled to create the natural colour view.

Farewell to Cassini on This Week @NASA
On Sept. 15, our Cassini spacecraft concluded its remarkable mission with a plunge into Saturn’s atmosphere. This was the last of 22 close orbits Cassini made between Saturn and its rings as part of the mission’s Grand Finale. No other spacecraft has ever explored this unique region. Although the spacecraft may be gone after the finale, the enormous amount of data collected about Saturn, its magnetosphere, rings and moons during this last dive is expected to yield new discoveries for decades.
