Magdalena Astronomy Club - Interpretation of time diffraction

 Can the future interacting with the past create the present?

In classic Newton mechanics answer is no. It is contradict the causality principle. But in quantum mechanics situation is much more complex. 

Just read article "Double-slit time diffraction at optical frequencies" which was published in Nature Physics April 03, 2023. Photons in future and past coming through Double split in time are creating diffraction in the present, and this is not theory - it is result of experiment!

I tried to explain it. First thinking about fantasy books which I read when was young. In this book people go to the past and after that return to the present and see that present was changed. Second thinking about retrocausality. It is opposite effect when the future changes the present. But interaction of the future and the past?

In the same time I thinking about Astronomical Club in Magdalena. And in some moment I got how to explain time diffraction. The future is The Karl G. Jansky Very Large Array (VLA), past is history of Magdalena city, near VLA, and current is the Astronomical club.

The VLA, Magdalena's history, and the Astronomical Club of Magdalena all illustrate how the future can interact with the past to create the present.

Magdalena's history shapes the present of the town and its people, and the Astronomical Club of Magdalena continues to appreciate and learn from the knowledge of the past while using modern technology to explore and understand the cosmos.

Ultimately, the future and the past are two sides of the same coin, each influencing and shaping the present in unique and meaningful ways.

The Karl G. Jansky Very Large Array (VLA)

 

These photos from my travel trip to New Mexico Very Large Array. 

The Karl G. Jansky Very Large Array (VLA) is a radio astronomy observatory located in central New Mexico, USA.

The VLA was first proposed in the 1960s as a replacement for the older National Radio Astronomy Observatory (NRAO) antennas. Construction began in 1973, and the VLA was completed in 1980. The VLA consists of 28 dish antennas that can be arranged in different configurations to observe different parts of the sky.

The VLA is a powerful tool for radio astronomy, as it is capable of observing a wide range of celestial objects, including stars, galaxies, and black holes. Because the VLA observes in the radio frequency range, it can see through dust clouds and other obstructions that would be opaque to visible light telescopes.

One of the most famous scientific discoveries made using the VLA was the confirmation of the existence of black holes. In 1974, astronomers using the VLA observed a radio source called Cygnus X-1, which was suspected to be a black hole. By observing the orbital motion of a companion star to Cygnus X-1, the astronomers were able to confirm that it was indeed a black hole.

In addition to the discovery of black holes, the VLA has made many other important scientific discoveries. For example, in 1998, astronomers using the VLA discovered the first radio-emitting magnetar, a type of neutron star with an extremely powerful magnetic field. The VLA has also been used to study the properties of interstellar gas and dust, as well as the formation of stars and galaxies.

The Karl G. Jansky Very Large Array (VLA) was also featured prominently in the 1997 science fiction film "Contact", based on the novel by Carl Sagan. The film tells the story of a scientist named Ellie Arroway, played by Jodie Foster, who uses the VLA to search for extraterrestrial intelligence.

In the film, Arroway and her team use the VLA to search for signals from other civilizations in the universe. The VLA's ability to detect faint radio signals from distant objects is crucial to their search, as they believe that other intelligent beings may use radio waves to communicate with one another.

"Contact" is a science fiction film that features the Karl G. Jansky Very Large Array as a key element in its plot. Although the film's depiction of the VLA is largely fictional, it did raise awareness of the observatory and its capabilities among the general public. The VLA remains a powerful tool for scientific research, and its ongoing use by astronomers and other scientists continues to expand our understanding of the universe.

I have only one day and night to make photos. Weather was not perfect. But I thing clouds give some drama to these photos.

Sky's The Limit Observatory

Here are some photos of Sky's The Limit Observatory and Nature Center from my trip to Joshua Tree National Park. This observatory is located just outside the park, between the north entrance and the town of Twentynine Palms, California.

Sky's The Limit is a well-known place for astronomy outreach in the Joshua Tree area. It is a nice place to visit both during the day and at night, with observatory domes, telescopes, and an open desert setting that fits very well with the spirit of Southern California astronomy.

Because Joshua Tree is famous for its dark skies, this observatory is also a natural stop for people interested in stargazing, amateur astronomy, and astrophotography. Even the surroundings already create the feeling that you are entering a place dedicated to the night sky.

At night the observatory becomes even more atmospheric, with the buildings and domes standing under the desert sky not far from Joshua Tree National Park.

This visit to Sky's The Limit Observatory was also part of my broader astrophotography trip to Joshua Tree National Park. It can also be compared with several other observatories and astronomy centers that I photographed in different parts of the world.

Cherry Springs State Park Pennsylvania Astrophotography

Located in north-central Pennsylvania at an elevation of about 2,300 ft (701 m), Cherry Springs State Park is one of the darkest places on the entire U.S. East Coast. The park is an officially recognized International Dark Sky Park and is famous among astronomers and astrophotographers for its pristine, high-altitude skies and excellent 360-degree horizon views.

The Milky Way Over the Observatory Domes

In the foreground you can see two astronomical domes, the distant forest line, and a fun set of signs reading “Galaxy” – “Slow Down” – “No Dust”. Above the scene, the Milky Way rises brightly across the sky.

Camera & Lens

  • Canon EOS 60Da (modified for astrophotography)
  • Canon EF 16–35mm f/2.8L II USM

Exposure Details

  • ISO 20,000
  • 15 sec exposure
  • f/2.8

Processing

Processed using Adobe Camera Raw, Photoshop, Topaz Denoise AI and Topaz Sharpen AI to reduce noise, enhance star clarity, and balance the color of the Milky Way.

About Cherry Springs: Why It’s Special

Cherry Springs State Park is considered one of the top stargazing sites in the eastern United States. Its remote location and high elevation mean exceptionally dark skies, often reaching Bortle Class 2. On moonless nights, the Milky Way is easily visible to the naked eye from horizon to horizon.

  • Very low light pollution
  • Dedicated astronomer field
  • Restricted vehicle movement after dark
  • No white lights allowed
  • Excellent southern horizon for Milky Way imaging

From NYC, the drive takes approximately five hours, leading deep into Pennsylvania forest land. When you arrive at night, the darkness feels almost unreal — perfect for astrophotography.

Daytime Photos from the Park

The following images were taken during the day to show how the park looks in normal light. This area includes the observatory domes, astronomer pads, fields, and surrounding forests. Cherry Springs has many fun details visible only in daylight — including the “Highway to the Stars” road sign near South 44, reminding visitors that they are entering one of the darkest and most famous stargazing locations in the eastern United States.

Cherry Springs remains one of my favorite dark-sky locations in the eastern United States. The combination of quiet forest surroundings, dedicated observatory domes, and extremely dark skies makes it a dream destination for night-sky photographers.

Visiting Tips

  • Best time for Milky Way: April–September (new moon weekends are best).
  • Bring red lights only: white light is prohibited.
  • Warm clothing: nights get cold even in summer.
  • Arrive before sunset: headlights are not allowed to enter the astronomy field after dark.
  • Reserve ahead: astronomer field can fill up on holidays or special events.
