Monday, September 30, 2019: In the remote Chilean Atacama Desert, the European Southern Observatory is laying the foundation for what will soon be the largest ground-based telescope in the world. Named the Extremely Large Telescope (ELT) will have a primary mirror that measures 129 feet (39.3 meters) in diameter, a 14-foot (4.2 m) secondary mirror and a 12-foot (3.75 m). Workers are currently building the foundation for the enormous observatory, which will have a dome-shaped enclosure measuring 243 feet (74 m) tall. — Hanneke Weitering

Friday, September 27, 2019: What may look like a big, bright smudge in this Hubble Space Telescope image is the dwarf galaxy Messier 110. Located in the Andromeda constellation, it is a satellite of the spiral-shaped Andromeda galaxy. Messier 110 doesn't have that same spiral structure, but rather is a smooth and featureless structure. But Messier 110 is not the only strange blob in this image; near the center of the frame is a dark splotch, which is a cloud of interstellar dust and gas. Another one of these dark clouds appears just above the bright core of Messier 110. — Hanneke Weitering

Thursday, September 26, 2019: The Suomi NPP weather satellite captured this view of an enormous dust storm in southern Africa yesterday. Coastal towns watched as the sky turned red from the thick plumes of dust and sand that rose into the air, and strong winds pushed those winds offshore into the Atlantic Ocean. 

Suomi NPP, which is operated jointly by NASA and the National Oceanic and Atmospheric Administration (NOAA), watched the dust storm in action when it flew over the scene at 2:25 p.m. local time (1225 GMT). Areas affected by the storm were located north and south of the Orange River, which forms part of the border between Namibia and South Africa, NASA officials said in a statement. — Hanneke Weitering

Wednesday, September 18, 2019: A brilliant aurora appears to rise like a glowing, green smoke plume from Concordia research station in Antarctica in this photo by  European Space Agency (ESA) photographer Alessandro Mancini. 

"I turn my gaze away from the horizon and dusk, there is a stripe in the sky that is not the Milky Way, at first just white and cloud-like, but there is no doubt — the green hues are visible and the curtain-like waves in the sky are unmistakable," ESA's on-site doctor Nadja Albertsen wrote in a blog post after witnessing the aurora at the remote research station. — Hanneke Weitering
 

Noctilucent Clouds Seen from Space

Tuesday, September 17, 2019: A wispy layer of mesospheric clouds illuminates Earth's atmosphere in this photo taken from the International Space Station. European Space Agency astronaut Luca Parmitano tweeted this photo from space, writing, "Mesospheric clouds tinge the sunset, south of the Indian Ocean." Mesospheric clouds, also known as noctilucent clouds, form 47 to 53 miles (76 to 85 kilometers) above Earth's surface, an altitude where water vapor can freeze into clouds of ice crystals. For comparison, the International Space Station orbits at an average altitude of 250 miles (400 km). — Hanneke Weitering

Monday, September 16, 2019: The faint galaxy UGC 695 shimmers in deep space in this view from the Hubble Space Telescope. Located 30 million light-years away within the constellation Cetus (The Sea Monster), UGC 695 is considered a low-surface-brightness galaxy, which means that it's even dimmer than the background brightness of Earth’s atmosphere, which makes it difficult to observe. While galaxies like this don't contain as many stars as their brighter counterparts, they are rich with dark matter. — Hanneke Weitering
 

The Large Magellanic Cloud

Friday, September 13, 2019: The Large Magellanic Cloud (LMC), one of the Milky Way's closest galactic neighbors, gets a new close-up in this image from the European Southern Observatory's VISTA telescope, located at the Paranal Observatory in Chile. VISTA, which stands for the Visible and Infrared Survey Telescope for Astronomy, has been studying this dwarf galaxy and its smaller galactic sibling, the Small Magellanic Cloud (SMC),  for the past decade to image the two galaxies in unprecedented detail. The LMC is located about 163,000 light-years away from Earth, while the SMC is slightly farther away at a distance of 200,000 light-years. Both are satellite galaxies of the Milky Way. — Hanneke Weitering
 

An Eerie 'Eye' on Saturn

Saturn's south pole looks a bit unsettling in this infrared view from NASA's Cassini spacecraft. At the center of a 5,000-mile-wide (8,000 kilometers) storm is an eerie red "eye" that looks similar to the eye of a hurricane on Earth. However, this strange vortex doesn't behave in the same way as our Earthly hurricanes, with its cloudy rings rising 20 to 45 miles (30-75 km) above the storm's center. Cassini captured this view from Saturn's orbit in 2006, and citizen scientist Kevin Gill reprocessed it using near-infrared filtered images.

Monday, September 9, 2019: When NASA's Mars Reconnaissance Orbiter flew over Schroeter Crater on the Red Planet, it captured views of some interesting smaller craters within the crater's floor. The two impact craters shown here are located inside Schroeter Crater, which is about 190 miles (300 kilometers) wide, and they contain some intricate dune structures on their own crater floors. These Martian dunes were shaped by wind, much in the same way that dunes form on Earth. — Hanneke Weitering

Thursday, Sept. 5, 2019: Four tropical cyclones simultaneously churn across the Western Hemisphere in this image from the GOES-16 weather satellite. When GOES-16 captured the data for this natural-color composite on Wednesday (Sept. 4), both Hurricane Dorian in the Atlantic and Hurricane Juliette in the Pacific were Category 2 storms. Hurricane Dorian has since strengthened to a Category 3 storm. Meanwhile, Tropical Storm Fernand has made landfall in northeastern Mexico, and Tropical Storm Gabrielle is gaining strength over the eastern Atlantic. You can see a full-disk version of this image in higher resolution here. — Hanneke Weitering
 

Stellar Feedback in a Barred Spiral Galaxy

(Image credit: ESO/R. Leaman/D. Gadotti/K. Sandstrom/D. Calzetti)

Wednesday, September 4, 2019: In this new view of the barred spiral galaxy NGC 3351, massive bubbles of hot gas are erupting from the galaxy's nucleus. Those gas bubbles will affect the formation of new stars in the interstellar medium, or the space between the stars in the galaxy. This process of redistributing mass and energy in star-forming galaxies is known as "stellar feedback," and it is a driving force in galactic evolution. 

Also known as Messier 95, this particular galaxy is location about 33 million light years away from Earth in the constellation of Leo, the Lion. Astronomers captured this image using data from the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. — Hanneke Weitering
