This week’s image is from the James Webb Space Telescope (JWST). It shows a spiral galaxy that appears much like our own (bottom center), though this one is a billion light-years away. Do occupants of that galaxy also see us? Good luck communicating when it will take 2 billion years to receive a response to a message you just sent out.

Here is the full story from the European Space Agency (ESA), which posted this as its Picture of the Month just last month:

A crowded field of galaxies throngs this Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope, along with bright stars crowned with Webb’s signature six-pointed diffraction spikes. The large spiral galaxy at the base of this image is accompanied by a profusion of smaller, more distant galaxies which range from fully-fledged spirals to mere bright smudges. Named LEDA 2046648, it is situated a little over a billion light-years from Earth, in the constellation Hercules.

One of Webb’s principle science goals is to observe distant galaxies in the early universe to understand the details of their formation, evolution, and composition. Webb’s keen infrared vision helps the telescope peer back in time, as the light from these distant galaxies is redshifted towards infrared wavelengths. Comparing these systems with galaxies in the local universe will help astronomers understand how galaxies grew to form the structure we see today. Webb will also probe the chemical composition of thousands of galaxies to shed light on how heavy elements were formed and built up as galaxies evolved.

Space Quote: Google’s Expensive Mistake Regarding the JWST

“What new discoveries from the James Webb space telescope (JWST) can I tell my nine-year old about?”

-The one question put to Google’s Bard AI program, which was designed to rival Microsoft’s ChatGPT. In response, Bard stated the JWST took the very first pictures of an exoplanet, which was incorrect. The first image of an exoplanet can be seen above, taken by the European Southern Observatory’s Very Large Telescope back in 2004. The exoplanet, called 2M1207 b, is a gas giant about five times the mass of Jupiter. Following the erroneous feedback, the stock of Google’s parent Alphabet dropped about $100 billion in value. Below is an image from another exoplanet spotted by the JWST last year, called HIP 65426 b, which is about six to eight times the mass of Jupiter.

The House Committee Dodged a Killer Asteroid

The House Committee on Science, Space, and Technology, which oversees NASA’s programs, may have a chance to get some things done this year. Earlier in the week, New York Congressman George Santos stepped down from the Committee on Science, Space, and Technology as well as the House Committee on Small Business. With all of the problems following this man, his presence on either committee would have been a pure distraction.

The House Committee on Science, Space, and Technology has a broad jurisdiction beyond just NASA:

The Committee on Science, Space, and Technology has jurisdiction over all energy research, development, and demonstration, and projects thereof and all federally owned or operated non-military energy laboratories; astronautical research and development, including resources, personnel, equipment, and facilities; civil aviation research and development; environmental research and development; marine research; commercial application of energy technology; National Institute of Standards and Technology, standardization of weights and measures and the metric system; National Aeronautics and Space Administration; National Science Foundation; National Weather Service; outer space, including exploration and control thereof; science scholarships; scientific research, development, and demonstration, and projects therefor. The Committee on Science, Space, and Technology shall review and study, on a continuing basis, laws, programs, and Government activities relating to non-military research and development.

Given the Artemis program as well as the other NASA endeavors currently underway, the Committee should be focusing as much time as possible on space missions rather than bogus resumes and lies to the public.

NASA-related hearings from last year include:

We need a serious Congress if we are going to conduct serious science and space exploration. Let’s hope Washington DC can keep its focus on the real stars (rather than the political black holes that can suck in all light and common sense).

Space Stories: Congressional Space Medal, Asteroid Rings, and Dancing Exoplanets

Here are some recent stories of interest.

—NASA: “VP Awards Former NASA Astronauts Congressional Space Medal of Honor“

On behalf of President Joe Biden, Vice President Kamala Harris awarded former NASA astronauts Douglas Hurley and Robert Behnken the Congressional Space Medal of Honor Tuesday for their bravery in NASA’s SpaceX Demonstration Mission-2 (Demo-2) to the International Space Station in 2020. Hurley and Behnken are the first recipients of the honor since 2006 and accepted the awards during a televised event in Washington.

—CNET: “NASA Webb Telescope Zooms in on One of Solar System’s Oddest Objects“

Scientists using NASA’s new James Webb Space Telescope say they’ve been able to get a closer look at an asteroid that also hosts just the fifth ring system to be discovered in our solar system (the others circle Saturn, Jupiter, Uranus and Neptune).  Astronomers initially discovered the rings in 2013 while watching Chariklo occult, or pass in front of, a distant star. To their surprise, two other smaller objects also appeared to pass in front of the background star for an instant. These turned out to be two thin rings around Chariklo. 

—Northwestern University: “Watch Distant Worlds Dance Around their Sun“

In 2008, HR8799 was the first extrasolar planetary system ever directly imaged. Now, the famed system stars in its very own video. Using observations collected over the past 12 years, Northwestern University astrophysicist Jason Wang has assembled a stunning time lapse video of the family of four planets — each more massive than Jupiter — orbiting their star. The video gives viewers an unprecedented glimpse into planetary motion. 

Even George Will is Excited about the JWST

George Will, political commentator, wrote an article for his Washington Post column this week that praised the James Webb Space Telescope (JWST). I am accustomed to his conservative politics and baseball trivia, but he was showing a whole new side in this piece. He was almost giddy in his praise of the telescope. I guess no one can avoid being fascinated with the images we have seen since July of last year, as well as what we are learning from these images. The universe has plenty of secrets to share.

Mr. Will was just as impressed with the engineering that went into the JWST, noting that:

To function, each mirror must, after being hurled into space on a shuddering rocket, retain this exquisite precision: If each mirror were the size of the continental United States, each should not vary more than 2 inches from perfect conformity with the others.

That is impressive.

It is just nice to see astronomy bleeding into everyday conversations, which is what is needed given the rest of the Earth-bound news these days. Yes, it is time to look up and look back in time to understand our place in the universe. Talk about science, be it astronomy or engineering, should replace the political talk from time to time.

There is nothing new under the sun when it comes of silly politicians, but the night sky always has something new to share with us. We just have to pay attention.
