Podcast: Assist UCLA with a SETI Project

Posted on by onespaceman2000

I found another episode from The Planetary Society’s podcast Planetary Radio that is worth checking out. In this episode, Are we Alone? The Search for Alien Technosignatures, Professor Jean-Luc Margot and doctoral student Megan Li discuss their project at University of California Los Angeles (UCLA) to identify signals from other civilizations in the galaxy and then extract information encoded in those extraterrestrial signals. This project, called UCLA SETI, was also the winner of a Planetary Society STEP Grant as well as a NASA grant to conduct this work.

As of last week, a volunteer site was set up to assist the UCLA SETI team with this project. Here is some key information from its website:

We host a citizen science collaboration on Zooniverse. Please consider partnering with us to identify the most interesting signals in our data. Subscribe to our newsletter to stay informed about our progress. Past issues of our newsletter are available.

Watch a two-minute video about the UCLA SETI course or a 30-minute talk about the search for life in the universe.

The video is actually a 55-minute talks, but the key section related to this project starts at the 23:38 minute mark where the downloaded data is discussed.

This is your chance to identify something that no one has every seen before. Put some of that time you might have spent watching The Ark toward something useful.

Television: UFOs and Star Trek

With all the ongoing media chatter about unidentified flying objects (UFO), National Geographic has perfect timing with its new series UFOs: Investigating the Unknown. The new series started on February 13th. You can watch it on Hulu, Disney+, and ESPN+.

National Geographic promises that this new five-part series will explore the government’s decades long investigations into UFOs. It seems those investigations just expanded into new areas with the U.S. Air Force recently firing missiles at objects in Canada and the United States. Maybe the new series can help to explain some of these sightings.

If the whole UFO issue has bored you, then tag along with Captain Picard for the third and last season of Star Trek: Picard. The series returned on February 16th. You get to see some of your old favorites joining the cast this season, including Geordi La Forge, Worf, William Riker, Dr. Beverly Crusher, and Deanna Troi.

Here is the basic plot from Paramount+:

In the epic, thrilling conclusion of Star Trek: Picard, a desperate message from a long-lost friend draws Starfleet legend Admiral Jean-Luc Picard into the most daring mission of his life, forcing him to recruit allies spanning generations old and new. This final adventure sets him on a collision course with the legacy of his past and explosive, new revelations that will alter the fate of the Federation forever.

I know, the plot reads like a cover letter on a resume promising everything. That said, I think I will start with Star Trek: Picard and continue to follow UFOs in the daily news. That will be enough drama for me these days.

What’s Going on at the International Space Station?

It appears that we now have two problematic capsules attached to the International Space Station (ISS). Late last year, we learned about a liquid coolant lead in the Russian Soyuz Crew Return Vehicle (Soyuz MS-22 crew ship), and now we have a leak in the second Russian capsule as well (Progress 82 cargo capsule). This is not a good sign for the seven ISS crew members, some of whom were already scheduled to go home.

After inspecting the Progress 82 spacecraft, it was set loose on Friday to burn up over the Pacific Ocean, as noted by NASA:

Loaded with trash, Progress 82 undocked from the space station’s Poisk module at 9:26 p.m. EST Friday, Feb. 17. The Progress deorbit was delayed about 24-hours while Roscosmos engineers analyzed imagery acquired after undocking of the radiator area of the spacecraft, which is the suspected region where a coolant leak occurred on Feb. 11.

As a result of this second incident, the Russian launch of a replacement capsule (Soyuz MS-23), scheduled for this week, may need to be delayed until the issues with both spacecraft are fully discussed and understood. In a discussion about the two leaks, an NPR commentator noted:

Analysts say Russia’s supply chain has been stretched thin due to the war in Ukraine.

This is not good news for anyone. If we cannot rely on the Russian missions, the SpaceX and Northrop Grumman will be doing double duty.

A Day in Astronomy: Discovery of Pluto

On this day in 1930, Clyde Tombaugh discovered Pluto. The 23-year old astronomer was working for the Lowell Observatory in Flagstaff, Arizona at the time of his discovery.

Pluto, recognized as the ninth planet in our solar system, was demoted to a dwarf planet in 2006 since it was one of many such objects in the Kuiper Belt and did not meet the definition of a planet.

When NASA’s New Horizons spacecraft visited Pluto in 2015, it was carrying some of Clyde Tombaugh’s ashes. The canister with the ashes had the following inscription:

Interned herein are remains of American Clyde W. Tombaugh, discoverer of Pluto and the solar system’s “third zone.” Adelle and Muron’s boy, Patricia’s husband, Annette and Alden’s father, astronomer, teacher, punster, and friend: Clyde W. Tombaugh (1906-1997).

You can learn a number of interesting facts about Pluto here.

Space Stories: Black Holes & Dark Energy, New Forms of Ice, and Dark Dwarf Galaxies

Here are some recent stories of interest.

—University of Hawaii: “First Observational Evidence Linking Black Holes to Dark Energy“

Searching through existing data spanning 9 billion years, a team of researchers led by scientists at University of Hawaiʻi at Mānoa has uncovered the first evidence of “cosmological coupling” –a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.

UH Mānoa astrophysicists Duncan Farrah, a faculty member at the Institute for Astronomy and the Department of Physics and Astronomy, and Kevin Croker, a professor of physics and astronomy led this ambitious study, combining Hawaiʻi’s expertise in galaxy evolution and gravity theory with the observation and analysis experience of researchers across nine countries to provide the first insight into what might exist inside real black holes.

—Astronomy.com: “Scientists Create New Form of Ice that Might Exist on Ocean Moons“

Chemists have discovered a new form of ice, and their work may have major consequences for our understanding of the outer solar system. We usually encounter three forms of water on the surface of Earth: solid, liquid, and vapor. On our planet, solid ice mainly comes in one variety, where water molecules arrange themselves into an orderly and repeated crystalline structure. But scientists have discovered 19 other varieties of water-ice that may appear throughout the universe.

—Phys.org: “Chinese Astronomers Discover an Isolated Dark Dwarf Galaxy“

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new galaxy, which received designation FAST J0139+4328. The newfound galaxy is isolated, has a relatively low stellar mass, and is dominated by dark matter. The discovery was detailed in a paper published February 6 on the arXiv pre-print server.
