APOD: 2026 September 27 – Andromeda Before and After Photoshop

Andromeda Before and After Photoshop

Explanation: What does the Andromeda galaxy really look like? The featured before image shows how our Milky Way Galaxy‘s closest major galactic neighbor really appears in a long exposure through Earth‘s busy skies and with a digital camera that introduces normal imperfections. The picture is a stack of 223 images, each a 300 second exposure, taken from a garden observatory in Portugal during 2019. Obvious image deficiencies include bright parallel airplane trails, long and continuous satellite trails, short cosmic ray streaks, and bad pixels. In the after image, these imperfections were actually not removed with Photoshop specifically, but rather greatly reduced with a series of computer software packages that included Astro Pixel Processor, DeepSkyStacker, and PixInsight. All of this work was done not to deceive you with a digital fantasy that has little to do with the real likeness of the Andromeda galaxy (M31), but to minimize Earthly artifacts that have nothing to do with the distant galaxy and so better recreate what M31 really does look like.

NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov touched down at NASA’s Kennedy Space Center in Florida, at 12:56 p.m. EDT, following a flight from the agency’s Johnson Space Center in Houston that included a brief refueling stopover in Mississippi.

A crew arrival media event is streaming live on NASA Kennedy’s YouTube channel, featuring the crew, as well as representatives from NASA Kennedy, and the agency’s Low Earth Orbit Program.

NASA’s SpaceX Crew-13 crew members will spend the remaining days before launch to the International Space Station in quarantine and conducting final preflight operations at Kennedy.

Liftoff aboard a SpaceX Falcon 9 rocket is targeted no earlier than 11:10 a.m. EDT Thursday, Oct. 1, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Crew-13 is SpaceX’s 13th crew rotation mission for NASA and the company’s 14th carrying NASA astronauts to the space station, including the Demo-2 test flight.

More details about the launch will be posted on the mission blog, @NASAKennedy on X, or NASA Kennedy on Facebook.

NASA’s SpaceX Crew-13 crew members are on their way to NASA’s Kennedy Space Center in Florida to prepare for launch to the International Space Station.

NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov took off in T-38s from Ellington Field near the agency’s Johnson Space Center in Houston this morning and are expected to land around 1 p.m. EDT at NASA Kennedy’s Shuttle Landing Facility. 

Upon landing, Crew-13 will be greeted on the runway by representatives from NASA Kennedy and the agency’s Low Earth Orbit Program, before speaking briefly with on-site media. Watch live coverage of the crew arrival media event on NASA Kennedy’s YouTube channel. 

After remarks, the crew will go to the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building, where they will continue to quarantine and complete prelaunch preparations.

Crew-13 will lift off aboard a SpaceX Falcon 9 rocket no earlier than 11:10 a.m. Thursday, Oct. 1, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

APOD: 2026 September 26 – Mirrored Meteor and Milky Way

 

APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A large, segmented telescope mirror is seen against the night sky along with the Milky Way and a bright meteor.

Mirrored Meteor and Milky Way

Explanation: On August 15, this perseid meteor streaked through night skies over the Observatorio del Roque de los Muchachos at La Palma, Canary Islands, Spain. The bright and colorful meteor trail was captured next to the central Milky Way, whose dark interstellar dust clouds and luminous starlight reach above the horizon. In the foreground of this tantalizing celestial scene is the 23 meter diameter mirror of the prototype Large-Sized Telescope (LST-1). LST-1 is the first telescope constructed at the northern hemisphere site of the innovative Cherenkov Telescope Array Observatory. With 198 hexagonal mirror segments and a large, high-efficiency, pixelized camera, LST-1 is designed to detect extremely brief, atmospheric visible light flashes. Lasting about a billionth of a second, the visible light flashes are triggered by energetic gamma-rays from cosmic sources such as distant active galaxies and gamma-ray bursts. Of course, on that night some individual mirror segments of LST-1 also reflected the atmospheric flash of the bright perseid meteor.

The crew members of NASA’s SpaceX Crew‑13 mission are set to touch down at the agency’s Kennedy Space Center at approximately 1 p.m. EDT on Saturday, Sept. 26, after flying in, arriving from the agency’s Johnson Space Center in Houston to begin their final days of launch preparations.

Watch the crew’s arrival live on NASA Kennedy’s YouTube channel. NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov will deliver brief remarks and take questions from media before heading to Astronaut Crew Quarters at Kennedy.

The crew’s arrival marks the start of an intensive period of suit checks, equipment reviews, and mission briefings as the crew prepares for their upcoming journey to the International Space Station. The crew will continue its quarantine protocols and complete final preflight operations, building on weeks of training and readiness milestones leading up to launch, targeted for no earlier than 11:10 a.m. Thursday, Oct. 1.

Continuing updates throughout launch week will be posted on the mission blog, @NASAKennedy on X, or NASA Kennedy on Facebook.
