President’s Message – Nov 2021

Posted by as President's Message

Everybody should have a good astro-project on the go. My current one concerns the timing of lunar eclipses.

Solar eclipse geography and timing is known with remarkable precision. So much so that people, including many members of our RASC community, are willing to plan long, difficult, and expensive trips to watch them. The timing and location of the earth’s shadow, or umbra, across the Moon during a lunar eclipse is much more variable and poorly understood.

I was delighted to learn that as far back as 1687, Philippe de la Hire published that the Earth’s shadow was larger than could be accounted for by an airless Earth, leading to lunar eclipses that start a few minutes earlier and end a few minutes later than expected. This was important work, because observing the timing of eclipses was, in principle, one way to measure longitude – as long as the expected timing was well established.

Moon on Dallas Road, Oct 8, 2021, by Randy Enkin

The problem arises from the complex nature of the earth’s atmosphere that obscures, diffracts and refracts the sun’s light on its way to the Moon. I first became aware of the role of amateur lunar crater eclipse timing just before the eclipse last May (which was clouded out), and I am certainly keen to try again on the upcoming lunar eclipse, starting around 23:19 PST on Thursday, November 18. If there are clear skies, I’ll be out with my telescope, noting the time to the tenth of a minute that the earth’s umbra darkens (“immersion”) and then departs (“emersion”) from various lunar craters. Sky and Telescope has been compiling these observations since 1956. Herald and Sinnott (2014) have analysed the compilation, extended back to 1842, with an amazing 22 539 observations. Their main conclusion is that the Earth is surrounded by a “notional eclipse-forming layer” that is 87km thick. It is a really surprising result, since even noctilucent clouds don’t show up that high in the atmosphere.

Herald and Sinnott point out that amateur uninstrumented observations provide continuity with the early observations in their compilation and provide insight into the visual response of the human eye. To help with the observations, Thursday- Friday November 18-19, I have annotated a picture of the full moon with the crater timings predicted by Fred Espenak. I hope some of you will join me making these simple but useful observations.

Look Up,
Randy Enkin, President@Victoria.RASC.ca

The Last Stargazers – Dr. Emily M Levesque – intro by David Lee

A bird that mimicked a black hole. The astronomer that discovered microwave ovens. A telescope that got shot. The science of astronomy is filled with true stories (and tall tales) of the adventures and misadventures that accompany our exploration of the universe. Join Dr. Emily Levesque, author of the new popular science book The Last Stargazers, to take a behind-the-scenes tour of life as a professional astronomer. We’ll learn about some of the most powerful telescopes in the world, meet the people who run them, and explore the crucial role of human curiosity in the past, present, and future of scientific discovery.

Dr. Emily Levesque is an astronomy professor at the University of Washington. Her work explores how the most massive stars in the universe evolve and die. She has observed for upwards of fifty nights on many of the planet’s largest telescopes and flown over the Antarctic stratosphere in an experimental aircraft for her research. Her academic accolades include the 2014 Annie Jump Cannon Award, a 2017 Alfred P. Sloan Fellowship, a 2019 Cottrell Scholar Award, and the 2020 Newton Lacy Pierce Prize.

Questions, Answers, and Questions

Randy Enkin using his sextant
Randy Enkin using his sextant

One satisfaction of astronomy is the sense of continuity with astronomers from all over the world and spanning the decades, centuries, and millennia. The wonders of the sky fill us with awe and provoke so many questions. I appreciate the multidisciplinary approach to answering these questions.

Today’s anecdote concerns an article published this week, with 25 authors from 5 countries. The Chinese Chang’e 5 probe brought back to Earth the first lunar samples in 4 decades. They targeted a place on the Moon that was suspected of being young, due to the region’s low density of craters. Galileo observed craters on the moon 400 years ago, but it was only in the 1960s that meteor impacts were confirmed to be the dominant mechanism of their origin.

The observational and theoretical development of celestial mechanics, universal gravitation, the solar nebula, and planetary accretion were all required to understand dating planetary surfaces, by measuring the size and number of craters. We also needed telescopes, rockets, robotics, petrology, geochemistry, and geochronology to complement the study. The Moon is the only planetary body where impact crater ages have been calibrated with radiometric dating, but there had been no samples so far measured that are between 3.2 and 0.8 billion years old. The new samples were dated at 1.96±.06 billion years, sitting in the middle of that gap and forcing a revision of the current crater dating method. The new date is very young for the Moon’s surface and brings up new questions, like why the Moon was still melting crust so recently.

Back-scattered electron (BSE) images and false color energy dispersive spectroscopy (EDS) element maps of the two fragments from the Chang’e 5 sample

I’m filled with a sense of connection with my fellow humans who can conceive of such questions, work on them from many different aspects over the centuries, answer some, and end up with even more questions. And I look up at the sky with happiness.

Look Up,

Transcript video of meeting

Dr. Michelle Kunimoto
Dr. Michelle Kunimoto

Dr. Michelle Kunimoto is a postdoctoral associate working on NASA’s Transiting Exoplanet Survey Satellite (TESS)mission. She leads the Quick Look Pipeline team at MIT which is dedicated to analyzing TESS data to discover and characterize exoplanets. As an undergraduate, her discoveries of four planet candidates landed her on the Forbes 30 Under 30 list in 2017. Michelle is BC born and raised and received both her undergraduate degree and her PhD at the University of British Columbia.

Finding Earth 2.0 – Dr. Michelle Kunimoto

Michelle spoke about how we find exoplanets, identify potentially “habitable” planets, about what she does as a researcher with NASA’s TESS mission, and how anyone can join the hunt for new planets.

  • Are we alone? What would other life look like?
  • Assuming Earth-like conditions for life
    • Small, rocky, watery planet with an atmosphere
    • In the habitable zone around a host star
    • Stars that are similar to our Sun – “just right” and stable, long-lived
  • 30 years ago, the first exoplanets were discovered by Alex Wolszczan and Dale Frail
  • Gordon Walker actually discovered an exoplanet back in 1988 from Victoria, but not confirmed until 2002
  • How to detect an exoplanet
    • Pulsar
    • Doppler shift due to Stellar Wobble – radial velocity
    • Transit – the method Michelle uses in her work
    • Direct Imaging
    • Astrometry
    • others…
  • Kepler – NASA’s first exoplanet discovery mission 
    • Used the transit method from 2009 to 2013
    • 150,000+ stars observed for 4 years
    • Revolutionized exoplanet by discovering over half of all dis
    • K2 mission extended the discoveries to 2018
  • Tess – NASA mission started in 2018
    • Full sky coverage
    • Orbits around the Earth in a following, elliptical orbit
    • 27 days to a full year of observations for each object
    • Automated detection, then manual verification to avoid false positives
    • Michelle has discovered 1,600 candidate planets
    • Whole mission has confirmed 152 out of 3,285 candidate planets
    • A total of 4,531 exoplanets have been discovered (not just from the Tess mission)
    • Diversity of exoplanets is extensive
    • TRAPPIST-1 System
      • 7 exoplanets
      • 3 in habitable zone, and Earth-sized
      • James Web space telescope will examine this system in detail
    • 20 candidate exoplanets have been discovered that are Earth-sized and appear to possibly support life as we know it
    • Keppler-452b – most Earth-like exoplanet
    • Transmission spectroscopy – detect the characteristics of an exoplanet’s atmosphere
    • Habitable Exoplanet Observatory – a proposed space telescope that will perform direct imaging of exoplanets
    • How you can hunt for exoplanets
      • Anyone can access the data from the Mikulski Archive
      • Michelle found 4 candidate planets during a summer project
      • Planet Hunters TESS site – the public can help with this work – just visual pattern detection
      • Anyone can join the TESS vetting team and interact with the rest of the team
    • Upcoming missions
      • PLATO – 2026 mission
