Galaxy UGC 685 | Hubble Space Telescope

Galaxy UGC 685 | Hubble Space Telescope
Distance: 15 million light years
This Picture of the Week shows a dwarf galaxy named UGC 685. Such galaxies are small and contain just a tiny fraction of the number of stars in a galaxy like the Milky Way. Dwarf galaxies often show a hazy structure, an ill-defined shape, and an appearance somewhat akin to a swarm or cloud of stars—and UGC 685 is no exception to this. Classified as an SAm galaxy—a type of unbarred spiral galaxy—it is located about 15 million light-years from Earth.

These data were gathered under the NASA/ESA Hubble Space Telescope’s LEGUS (Legacy ExtraGalactic UV Survey) Program, the sharpest and most comprehensive ultraviolet survey of star-forming galaxies in the nearby Universe.

LEGUS is imaging 50 spiral and dwarf galaxies in our cosmic neighborhood in multiple colors using Hubble’s Wide Field Camera 3. The survey is picking apart the structures of these galaxies and resolving their constituent stars, clusters, groups, and other stellar associations. Star formation plays a huge role in shaping its host galaxy; by exploring these targets in detail via both new observations and archival Hubble data, LEGUS will shed light on how stars form and cluster together, how these clusters evolve, how a star’s formation affects its surroundings, and how stars explode at the end of their lives.

Earth Boat Lights & Starlight | International Space Station

Earth Boat Lights & Starlight | International Space Station
Did you see the lightning flashes over the ocean?

The orange hue enveloping Earth is known as airglow—diffuse bands of light that stretch 50 to 400 miles into our atmosphere.

Airglow occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light in order to shed their excess energy. Or, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron. In both cases, they eject a particle of light—called a photon—in order to relax again. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by day-to-day solar radiation.

Hurricane Dorian | NOAA Satellite

Hurricane Dorian | NOAA Satellite
NOAA's GOES East weather satellite captured this GeoColor view of Hurricane Dorian, a powerful Category 5 storm. Its maximum winds have increased to near 175 mph with gusts over 200 mph.

GeoColor is a multispectral product composed of True Color (using a simulated green component) during the daytime, and an Infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would appear when viewed with human eyes from space.

Geocolor was developed at the Cooperative Institute for Research in the Atmosphere (CIRA) and STAR's Regional and Mesoscale Meteorology Branch (RAMMB).

Views of Hurricane Dorian (Category 5) on September 1, 2019
Cameras outside the International Space Station captured views on September 1 of Hurricane Dorian from 260 miles in altitude at 12:16 p.m. Eastern time as it churned over the Atlantic Ocean over the northern Bahamas. The storm, which is moving in a westerly direction with sustained winds of 180 miles an hour, is a dangerous Category 5 hurricane, carrying the strongest winds in recorded history for the northwestern Bahamas. The National Hurricane Center said in its 11 a.m. EDT advisory that Dorian is inflicting catastrophic damage to the Abacos and Grand Bahama Islands. Dorian is forecast to approach the east coast of Florida before taking a possible track up the southeastern U.S. seaboard later this week.

Human research kept the Expedition 60 crew busy today helping NASA and its partners understand how to keep astronauts healthy on long-term space missions. More spaceship activity is also coming up in September to ensure a well-stocked and fully staffed International Space Station.

NASA astronauts Nick Hague and Andrew Morgan continued researching how fluid shifts caused by microgravity induce vascular changes as well as head and eye pressure. The duo processed more blood and urine samples today for the ongoing study observing the potentially risky condition.

Doctors on the ground are exploring telemedicine as a way to examine astronauts orbiting Earth and farther in space. Flight Engineer Luca Parmitano of ESA (European Space Agency) set up and held a remotely controlled ultrasound scanner to his femoral artery for the Vascular Echo study today. A doctor on Earth then guided the device’s motorized probes during the cardiovascular exam.

NASA Flight Engineer Christina Koch set up protein crystal samples for stowage inside an automated incubator. The research takes advantage of microgravity’s weightlessness to support the development of advanced pharmaceutical therapies.

The Soyuz MS-14 spacecraft continues to be unpacked by cosmonauts Alexey Ovchinin and Alexander Skvortsov. They will soon load the crew ship back up with more cargo for return to Earth next week.

Another crew ship, the Soyuz MS-15, is being processed for its launch to the station on Sept. 25. Commander Oleg Skripochka will lead Flight Engineer Jessica Meir and Spaceflight Participant Hazzaa Ali Almansoori on a six-hour ride to their new home in space. The new trio along with their backups began two days of qualification exams today.

In between the Soyuz missions, the H-II Transfer Vehicle-8 (HTV-8) is due to blast off Sept. 10 from the Tanegashima Space Center in Japan. It will take a four-day trip to the orbiting lab and deliver new batteries for the Port-6 truss power channels. It will be robotically captured and installed to the Harmony module for a month-long stay.

Hubble's 29th Birthday Celebrations!
This video takes the viewer on a journey into the 29th anniversary image NASA/ESA Hubble Space Telescope, the Southern Crab Nebula. This peculiar nebula, which exhibits nested hourglass-shaped structures, has been created by the interaction between a pair of stars at its center. The unequal pair consists of a red giant and a white dwarf. The red giant is shedding its outer layers in the last phase of its life before it too lives out its final years as a white dwarf.

Hubble Celebrates its 29th Birthday!
Hubblecast 119 | On April 18, 2019, Hubble celebrated its 29th year in space. For this anniversary, NASA and the European Space Agency (ESA) dedicated a small amount of its precious observation time to take a look at the beautiful Southern Crab Nebula. This beautiful nebula is created by the ejected material of a red giant, which is in close interaction with a white dwarf star.

The Southern Crab Nebula | Hubble's 29th Birthday

The Southern Crab Nebula 
Hubble Celebrates its 29th Birthday!

This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope’s 29th anniversary in space. The nebula, created by a binary star system, is one of the many objects that Hubble has demystified throughout its productive life. This new image adds to our understanding of the nebula and demonstrates the telescope’s continued capabilities.

On April 24, 1990, the NASA/ESA Hubble Space Telescope was launched on the space shuttle Discovery. It has since revolutionized how astronomers and the general public see the Universe. The images it provides are spectacular from both a scientific and a purely aesthetic point of view.

Each year the telescope dedicates a small portion of its precious observing time to take a special anniversary image, focused on capturing particularly beautiful and meaningful objects. This year’s image is the Southern Crab Nebula, and it is no exception [1].

This peculiar nebula, which exhibits nested hourglass-shaped structures, has been created by the interaction between a pair of stars at its center. The unequal pair consists of a red giant and a white dwarf. The red giant is shedding its outer layers in the last phase of its life before it too lives out its final years as a white dwarf. Some of the red giant’s ejected material is attracted by the gravity of its companion.

When enough of this cast-off material is pulled onto the white dwarf, it too ejects the material outwards in an eruption, creating the structures we see in the nebula. Eventually, the red giant will finish throwing off its outer layers, and stop feeding its white dwarf companion. Prior to this, there may also be more eruptions, creating even more intricate structures.

Astronomers did not always know this, however. The object was first written about in 1967, but was assumed to be an ordinary star until 1989, when it was observed using telescopes at the European Southern Observatory’s La Silla Observatory. The resulting image showed a roughly crab-shaped extended nebula, formed by symmetrical bubbles of gas and dust.

These observations only showed the outer hourglass emanating from a bright central region that could not be resolved. It was not until Hubble observed the Southern Crab in 1999 that the entire structure came into view. This image revealed the inner nested structures, suggesting that the phenomenon that created the outer bubbles had occurred twice in the (astronomically) recent past.

It is fitting that Hubble has returned to this object twenty years after its first observation. This new image adds to the story of an active and evolving object and contributes to the story of Hubble’s role in our evolving understanding of the Universe.

Notes
[1] The Southern Crab Nebula is so named to distinguish it from the better-known Crab Nebula, a supernova remnant visible in the constellation of Taurus.
