Mars: Avalanche Season | NASA MRO

Avalanche captured from Mars orbit by NASA's Mars Reconnaissance Orbiter (MRO) spacecraft

Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.

When they reach the bottom of the more than 500 meter tall cliff face, the blocks kick up a cloud of dust. The layers beneath are different colors and textures depending on the amount of dust mixed with ice.

Three Storms Brewing as Hurricane Season Heats Up

Three Storms Brewing as Hurricane Season Heats Up

While Hurricane Dorian lashed the Bahamas throughout Labor Day weekend, two other storms were brewing — one in the Atlantic, and another in the Eastern Pacific. In this GOES West view, captured at 1:20 p.m. EDT on Sept. 3, 2019, you can see all three storms.

Dorian, still a daunting Category 2 storm with maximum sustained winds of 110 mph, is threatening the U.S. mainland as the storm slowly moves to the northwest. Hurricane warnings are in effect from Jupiter Inlet to Ponte Vedra Beach in Florida, as well as from north of Edisto Beach to South Santee River in South Carolina. Although Dorian isn’t forecast to make landfall along the East Coast, with the storm’s increasing size, any deviation to the left of the track could bring hurricane-force winds to portions of Florida’s east coast, according to the National Hurricane Center (NHC).

As Dorian treks along the coast, Tropical Storm Fernand is slowly strengthening in the Gulf of Mexico. This storm, which currently has maximum sustained winds of nearly 40 mph, is forecast to reach the northeastern coast of Mexico late Tuesday or early Wednesday. A tropical storm warning is now in effect for Barra del Tordo to the mouth of the Rio Grande River, according to the latest NHC update.

Although Hurricane Juliette, a Category 3 storm as of 2 p.m. on Sept. 3, 2019, is packing wind speeds near 125 mph, this storm isn’t forecast to affect land. While the storm may gain some strength throughout the day, the NHC forecast shows the storm beginning to slowly fizzle by late Wednesday.

Dorian Pulling Away from Northwest Bahamas, Lashing Florida's East Coast

Dorian Pulling Away from Northwest Bahamas, Lashing Florida's East Coast

Dorian is tied for the strongest Atlantic hurricane landfall on record with the 1935 Labor Day hurricane by having maximum sustained winds of 185 mph (295 km/h), according to the National Hurricane Center (NHC).

The Eye of Hurricane Dorian | International Space Station

The Eye of Hurricane Dorian | International Space Station

". . . You can feel the power of the storm when you stare into its eye from above. Stay safe everyone!"

—NASA Astronaut Nick Hague (ISS Expedition 60)

Sept. 2, 2019: In its 11:00 a.m. EDT advisory, the National Hurricane Center said Dorian was almost stationary, moving toward the west at just 1 mile an hour just over 100 miles east of West Palm Beach, Florida, packing catastrophic sustained winds of 155 miles an hour.

A slow westward to west-northwestward motion is forecast during the next day or so, followed by a gradual turn toward the northwest and north. On this track, the core of extremely dangerous Hurricane Dorian will continue to pound Grand Bahama Island through much of today and tonight. The hurricane will move dangerously close to the east coast of Florida tonight through Wednesday evening and dangerously close to the Georgia and South Carolina coasts Wednesday night and Thursday.

Currently, Dorian is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Although gradual weakening is forecast, Dorian is expected to remain a powerful hurricane during the next couple of days while moving on a possible track up the southeastern U.S. seaboard.

Galaxy NGC 3351: Caught in the Act | European Southern Observatory

Galaxy NGC 3351: Caught in the Act | ESO

NGC 3351, also known as Messier 95, was first discovered in 1781 by Pierre Méchain, a French astronomer and surveyor who worked alongside Charles Messier. NGC 3351 is a type of galaxy known as a barred spiral galaxy and it is located in the constellation of Leo (The Lion).

New observations of this object have shown stellar feedback in action. Stellar feedback is the process of redistributing energy into the interstellar medium (the space in between the stars) within star-forming galaxies. In this particular galaxy, star formation is occurring in the ring surrounding the galaxy nucleus at such a violent rate that massive bubbles of hot gas can actually be seen being ejected. This ejected gas can then contribute (both positively and negatively) to ongoing star formation within the galaxy.

The data for this observation were taken with ALMA, the NASA/ESA Hubble Space Telescope and the Very Large Telescope, showing once again that scientific collaboration across multiple facilities can produce some wonderful results.

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

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.

In this month's sky, look for lovely crescent Moons at the start and end of the month. The September equinox brings the beginning of fall in the Northern Hemisphere. And Mars is at solar conjunction, meaning it has disappeared from night skies! (When will it return?)
