Views of Hurricane Florence | International Space Station
Sept. 10, 2018: Cameras outside the International Space Station captured dramatic views of rapidly strengthening Hurricane Florence at 8:10 a.m. EDT Sept. 10 as it moved in a westerly direction across the Atlantic, headed for a likely landfall along the eastern seaboard of the U.S. late Thursday or early Friday. Now a major hurricane with winds of 115 miles an hour and increasing, the National Hurricane Center says Florence’s forecast track will take the system over the southwestern Atlantic Ocean between Bermuda and the Bahamas Tuesday and Wednesday, and Florence will approach the coast of South Carolina or North Carolina on Thursday. The station was flying 255 miles over the storm at the time this video was captured.

Awesome Galactic Gravity | Hubble
Gravity is so much a part of our daily lives that it is all too easy to forget its awesome power—but on a galactic scale, its power becomes both strikingly clear and visually stunning.
This image was taken with the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3) and shows an object named SDSS J1138+2754. It acts as a gravitational lens illustrates the true strength of gravity: A large mass—a galaxy cluster in this case—is creating such a strong gravitational field that it is bending the very fabric of its surroundings. This causes the billion-year-old light from galaxies sitting behind it to travel along distorted, curved paths, transforming the familiar shapes of spirals and ellipticals (visible in other parts of the image) into long, smudged arcs and scattered dashes.
Some distant galaxies even appear multiple times in this image. Since galaxies are wide objects, light from one side of the galaxy passes through the gravitational lens differently than light from the other side. When the galaxies’ light reaches Earth it can appear reflected, as seen with the galaxy on the lower left part of the lens, or distorted, as seen with the galaxy to the upper right.
This data were taken as part of a research project on star formation in the distant Universe, building on Hubble’s extensive legacy of deep-field images. Hubble observed 73 gravitationally-lensed galaxies for this project.

Starburst Jewel
Like a July 4 fireworks display, a young, glittering collection of stars looks like an aerial burst. The cluster is surrounded by clouds of interstellar gas and dust—the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603. This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the gas and dust enveloping the cluster, providing an unobstructed view of the cluster.
Most of the stars in the cluster were born around the same time but differ in size, mass, temperature, and color. The course of a star's life is determined by its mass, so a cluster of a given age will contain stars in various stages of their lives, giving an opportunity for detailed analyses of stellar life cycles. NGC 3603 also contains some of the most massive stars known. These huge stars live fast and die young, burning through their hydrogen fuel quickly and ultimately ending their lives in supernova explosions.
Star clusters like NGC 3603 provide important clues to understanding the origin of massive star formation in the early, distant universe. Astronomers also use massive clusters to study distant starbursts that occur when galaxies collide, igniting a flurry of star formation. The proximity of NGC 3603 makes it an excellent lab for studying such distant and momentous events. This Hubble Space Telescope image was captured in August 2009 and December 2009 with the Wide Field Camera 3 in both visible and infrared light, which trace the glow of sulfur, hydrogen, and iron.

Celestial Fireworks: Into Star Cluster Westerlund 2
On July 4, 2017, APoD shared a nice video (► Take a look at>> https://www.youtube.com/watch?v=dtY44sPNHcU), from which I excerpted the clip below.
Some information about this video named "Celestial Fireworks: Into Star Cluster Westerlund 2".
The nebula Gum 29 (or RCW 49) is a star-forming region at least 13,700 light years away (or more, based on some estimates) in the constellation of Carina, in the southern Galactic plane of our Milky Way galaxy. One of the most prolific birthing grounds, RCW 49 is a dark and dusty stellar nursery that houses more than 2,200 stars. Because many of the stars in RCW 49 are deeply embedded in plumes of dust, they cannot be seen at visible wavelengths. When viewed with Spitzer's infrared eyes, however, RCW 49 becomes transparent.
At the core of this nebula is Westerlund 2, an obscured compact young star cluster (perhaps even a super star cluster) in the Milky Way, containing several thousand stars.
These newborn stars are approximately 2 million years old, and their light illuminates, heats, and erodes the surrounding gas.
As its name indicates, the Westerlund 2 cluster was discovered by Bengt Westerlund in the 1960s but its stellar content was assessed only in later years.
On 23 April 2015 an image of the Westerlund 2 cluster was chosen to celebrate the 25th anniversary of the Hubble Space Telescope.
The visualization, previously mentioned, provides a three-dimensional perspective on the nebula and star cluster. The flight traverses the foreground stars and approaches the lower left rim of the nebula. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed star cluster.
Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars.
Note that the visualization is intended only as a scientifically reasonable interpretation and that distances within the model are significantly compressed.

SpaceX Falcon 9 Launch: Telstar 18 Vantage Mission
The Falcon 9 Rocket’s 60th Successful Mission
Liftoff at 14-minute mark
SpaceX launched its second heavyweight Telstar telecommunications satellite from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida early Monday morning, Sept 10, 2018. It then brought the Falcon 9 rocket’s first-stage booster down for a landing on SpaceX's East Coast drone ship, named "Of Course I Still Love You", located hundreds of miles offshore in the Atlantic Ocean.
The SpaceX mission successfully placed the 15,600-pound Telstar 18 Vantage satellite into geostationary transfer orbit (GTO) for Canadian-based Telesat. Telstar 18V will provide constant broadband communications services to China, Mongolia, Southeast Asia, and the Pacific Ocean region.
