Volunteer Opportunity: Astronomer in Residence

Posted on by onespaceman2000

Looking for something to do next summer? How about being the Astronomer in Residence at the Grand Canyon? You can share your love of astronomy with the public on a regular basis. Doesn’t that sound like fun?

Here is more information on the position itself:

Grand Canyon Conservancy’s (GCC) Astronomer-in-Residence program supports astronomers and dark-sky advocates from various disciplines that wish to engage with the night skies of Grand Canyon and build connections with the community by sharing their expertise, instruments, and passion with the park’s public.  

Astronomers, both professional and amateur, scientists from ecologists to geologists, dark-sky advocates, educators, writers, and other practitioners with expertise in the night sky are encouraged to apply. We prioritize local Indigenous storytellers who focus on the night sky, and other night sky practitioners from marginalized communities across the United States and beyond.

Selected astronomers live and work at the Grand Canyon South Rim in Arizona for up to six weeks in a private one-bedroom apartment above the historic Verkamp’s Visitor Center overlooking the Canyon. In addition to free live/workspace, a modest stipend is offered to offset the costs of travel, food, and supplies. Residents have first-hand access to the natural beauty of Grand Canyon National Park, park leadership, staff expertise, on-site resources, archives, and visitors from around the world.   

You can learn more about the program here. Applications are being accepted through July 31st for the 2024 program.

Space Quote: Losing Our View of the Starry Night

“In 2016, astronomers reported that the Milky Way was no longer visible to a third of humanity and light pollution has worsened considerably since then. At its current rate most of the major constellations will be indecipherable in 20 years, it is estimated. The loss, culturally and scientifically, will be intense.”

-Statement in an article in The Guardian, titled “Stars Could be Invisible Within 20 years as Light Pollution Brightens Night Skies.” One scientist quoted in the article added, “A couple of generations ago, people would have been confronted regularly with this glittering vision of the cosmos – but what was formerly universal is now extremely rare. Only the world’s richest people, and some of the poorest, experience that any more. For everybody else, it’s more or less gone.”

Second TROPICS Launch a Success

The second and final TROPICS satellites, also known as Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats, were launched late yesterday via a Rocket Lab rocket in New Zealand. The first pair were launched earlier this month.

Rocket Lab sent out this message:

Payload deployment confirmed! Congratulations to the launch team on our 37th Electron launch, and to our mission partners at @NASA @NASA_LSP @NASAAmes: the TROPICS constellation is officially on orbit!

NASA now has more eyes on the world’s weather patterns. The lead of NASA’s Earth Science Division, Karen St. Germain, stated:

As we move into hurricane season for 2023, TROPICS will be in position to provide unprecedented detail on these storms, helping us better understand how they form, intensify, and move across the ocean.

Pic of the Week: Stellar Birth in NGC 1333

This week’s image is from the Hubble Space Telescope. It captures the colorful, star-filled NGC 1333, which is about 960 light-years away. Quite a lot is going on in this image – both seen and unseen.

This explanations from the European Space Agency (ESA) will hopefully answer many of your questions regarding this image:

Hubble’s colourful view, showcasing its unique capability to obtain images in light from ultraviolet to near-infrared, unveils an effervescent cauldron of glowing gases and pitch-black dust stirred up and blown around by several hundred newly forming stars embedded within the dark cloud. Even then, Hubble just scratches the surface; most of the star-birthing firestorm is hidden behind clouds of fine dust — essentially soot — that are thicker toward the bottom of the image. The black areas of the image are not empty space, but are filled with obscuring dust.

To capture this image, Hubble peered through a veil of dust on the edge of a giant cloud of cold molecular hydrogen — the raw material for fabricating new stars and planets under the relentless pull of gravity. The image underscores the fact that star formation is a messy process in a rambunctious Universe.

Ferocious stellar winds, likely from the bright blue star at the top of the image, are blowing through a curtain of dust. The fine dust scatters the starlight at blue wavelengths.

Farther down, another bright super-hot star shines through filaments of obscuring dust, looking like the Sun shining through scattered clouds. A diagonal string of fainter accompanying stars looks reddish because the dust is filtering their starlight, allowing more of the red light to get through.

The bottom of the picture presents a keyhole peek deep into the dark nebula. Hubble captures the reddish glow of ionised hydrogen. It looks like the finale of a fireworks display, with several overlapping events. This is caused by pencil-thin jets shooting out from newly forming stars outside the frame of view. These stars are surrounded by circumstellar discs, which may eventually produce planetary systems, and powerful magnetic fields that direct two parallel beams of hot gas deep into space, like a double lightsaber from science fiction films. They sculpt patterns on the hydrogen cocoon, like laser lightshow tracings. The jets are a star’s birth announcement.

This view offers an example of the time when our own Sun and planets formed inside such a dusty molecular cloud, 4.6 billion years ago. Our Sun didn’t form in isolation but was instead embedded inside a mosh pit of frantic stellar birth, perhaps even more energetic and massive than NGC 1333.

Television: Stars on Mars

The silly reality shows are now reaching for the stars, or at least a distant planet, with William Shatner leading the way. Fox’s new program Stars on Mars, premiering on June 5th, will feature numerous celebrities trying to survive in a “Mars-like” atmosphere. Planned guests include Lance Armstrong, Olympic figure skater Adam Rippon, professional football player Richard Sherman, and others.

I have no plans to watch this show, but I expect it may encourage support for space travel given that many of those who do watch the show will want to quickly leave this planet in the hopes of finding intelligent life somewhere.

NASA may be having funding problems, but bad TV always seems to find someone with deep pockets.
