The densest star cluster in our galaxy



Hubble Peers into the Most Crowded Place in the Milky Way


This Hubble Telescope image shows the Arches Cluster, the densest star cluster in the Milky Way. It is located about 25,000 light-years from Earth in the constellation of Sagittarius. It is a relatively young star cluster between two and four million years old. The Arches cluster is so dense that in a region with a radius equal to the distance between the Sun and its nearest star there would be over 100,000 stars. At least 150 stars within the cluster are among the brightest ever discovered in the Milky Way.

These stars burn their fuel within a few million years, expiring in supernova explosions. Due to their short lifetime the gas between the stars contains a high amount of heavier elements, the residue of earlier generations of stars.

Geek Mommies of Princeton


Alice C. Linsley

I recently visited my daughter to meet my new grandson, Sebastian (shown below). My daughter lives near Princeton, New Jersey, and is a member of an unusual group.

The Geek Mommies of Princeton has about 40 members and the only criteria for membership is that you be a mother and curious about the world. The young mothers get together monthly to inquire, question, explore, and share their thoughts about child care and how to encourage their children in STEM.

Monthly activities include potlucks, children's book exchanges, afternoon tea at the Buck's County Children's Museum, and science experiments. The children have learned about propulsion, making a volcano, and painting with spices and teas.

There is also a weekly play date with about 5 regular participants.

Mothers also read and discuss science fiction, fantasy, biographies and articles on sustainable living.

This group can serve as a model for other similar groups in which children are nurtured in an environment of inquisitive exploration and play.

Arguing False Choices on Human Origins


Alice C. Linsley

In the following Facebook thread some friends asked excellent questions and I asked their permission to post this at JUST GENESIS. This is the sort of conversation that can help people sort through the issues.

The conversation arose in response to this article about the discovery of trillions of stone artifacts in Africa. The article was posted by a Christian geologist. If humans have been on the earth only 5000-6000 years, they could not have produced the volume of work found at the stone working sites in Africa. At 40 million artifacts per year, it would take a population of 100,000 individuals 100,000 years to produce just 4 trillion artifacts.


  • Can there be a a conversation or a dialectic between the facts that make for one's faith and the narrative of "Genesis" that makes for the faith of "creationists" regarding the age of the earth and the origin of man. Can such a dialogue be possible?  - Sidney Davis

  • Alice Linsley Everything is possible, Sidney, but some conversations are less possible than others. Defining the term "creationist" is where we have to begin. There are different groups: young earth creationism, which is neither scientific nor Biblical; theistic creationism which is very popular with Evangelicals who accept evolutionary theories, some of which have no material support; old earth creationists who believe the Creator initiated creative or generative processes that resulted in humans, and old earth creationists who believe that humans represent a special creation, a sort of crown on the creation pyramid. Some of these are mutually exclusive positions and a dialectic between them is virtually impossible. I find it a waste of time to discuss Genesis with people who believe that the earth is only 6000 years old.

Ruth Bancewicz on Her Book: God in the Lab


What is it like to be a person of faith and a scientist? In a video interview the theologian and former biophysicist Alister McGrath commented that we need Christian scientists who are “prepared to enter into the public arena in debate, in comment, and in the writing of books showing how faith enriches their science.”

This blog has been one such attempt to show the positive effect of science on faith, and judging by the comments over the years, it has encouraged a number of people in that direction. On the 15th of this month, Monarch will publish my book God in the Lab: How Science Enhances Faith, which draws together these themes into a more coherent whole.

God in the Lab comes out of my enjoyment of science, my interest in hearing other scientists’ stories, and my desire to share the experience of working in a lab. It shows how creativity and imagination are vital to the practice of both science and Christianity. It looks at the ways in which beauty, wonder and awe can raise deeper questions about the world, and it gives six working scientists a voice in the science-faith arena.


When I interviewed Harvey McMahon, Ruth Hogg, Jennifer Siggers, Jeff Hardin, Rhoda Hawkins and Bob Sluka, I asked them about their work and beliefs, how the two fit together, and how science enhances their faith. Alongside these conversations, I explored the literature on each topic, in both science and theology. Thankfully, when I married the two sets of material together and showed it to the scientists, they were happy with my portrayal of their life and the way in which I had woven together their comments with my gleanings from the library.

My aim in this project – the blog and book, my talks and other activities over the last three and a half years – was to start some new discussions. I wanted to bring to the fore some areas of human experience that we can all identify with, whatever our religious or educational background. I wanted to show that Christianity is not just complementary to science, but it can also be enhanced by our exploration of the world.

When I started working for Christians in Science back in 2004, I was encouraged by something that Oliver Barclay, former General Secretary of the University and Colleges Christian Fellowship, wrote to one of our committee members after a request for help in dealing with certain science-faith issues. He suggested that one of the things we focus on is the wonder of the world that science reveals.

Regardless of our views on Genesis, or even the existence of a God, we can all identify with the sense of awe that hits us when we see something vast, beautiful or complex. The night sky, an ancient forest, microscopic organisms, or an equation – these all affect different people in different ways, but most of us will find something in nature or our exploration of it that is arresting and inspiring.

I deliberately finished God in the Lab with a chapter on awe because it leads most directly to questions of God for some, and worship for others. This is the part of the discussion on science and faith that often affects people most deeply. Some find a bleak world that we must find our way in, enjoying awe and wonder when we can. Others experience spirituality, and many encounter a personal God. My hope is that this book will start discussions that help us to hear each other, find points of common interest, and learn to appreciate the life of a scientist-believer.

Meet Hannah Ryan: A PROFILE OF TRANSFORMATION


Hannah Ryan recently joined the American Scientific Affiliation (ASA) executive council as the student and early career representative.
      
Hannah Ryan
Graduate Student in Colorado


Hobbies: Playing the violin, reading theology, trail running, baking, writing letters, and drinking coffee with friends.

When did you first discover American Scientific Affiliation (ASA)?
I first heard about ASA as an undergraduate student at Westmont College.

How has your personal and spiritual life been changed because of your involvement with ASA?
The annual ASA conference at McMaster University was quite a formative experience for me. It was such a unique time to dialogue and fellowship with Christian scientists who are passionate about God’s Kingdom and the beauty revealed in science. I found the plenary sessions and short talks incredibly stimulating, and the issues presented made me think deeply about theology, apologetics, biblical hermeneutics, and science. I think that wrestling through a belief can lead to stronger conviction on the other side. And that certainly happened to me. My involvement with ASA has grown me into a more thoughtful and effective believer in Jesus Christ. 

What is the tangible evidence of the growth you've experienced?
I think the best evidence I have seen in my own life of ASA’s influence is the increased confidence I have in conversations about science and faith, whether that be with a high school student at youth group, a peer student in graduate school, a professor, or a non-believing skeptic. I am more informed about current topics in science and faith. And in this way, ASA has developed my apologetic skills, increasing my tool kit of rationalities and justifications of faith and teaching me how to engage with either the science-worshiping or science-fearing mind.

 How long have you been a member/donor and what has ASA meant to you?
I joined the organization as a member in February 2014. While searching for an article on genetic evolution, I stumbled upon the ASA website and noticed the upcoming conference in Hamilton, Ontario, and right away I knew I wanted to become a member and submit an abstract!

What do our friends and financial partners need to know about how ASA is making a difference?
ASA has an invaluable ministry to students. I don’t know of any other organization that really covers the bases that ASA does for science-minded young people. For me personally, there have been times where the overbearing worldview of secular academia was oppressive and disorienting. It was a gift to find a community of brilliant and passionate scholars who are deeply committed to Christ and could specifically encourage me in my faith journey.

ASA can reach young Christian scientists and equip them with tools to become strong leaders in their field and faithful proclaimers of truth. Additionally I think that ASA has wonderful potential to reach students who may be teetering on the edge of religious belief. I have found that often non-believing students have a misconception of Christianity, do not honestly assess their own doubts, and may be straying in false philosophical assumptions. The ASA community is qualified to minister to these types of students and explain the relevance of the Gospel in this context.

Fewer Women in Biblical Archaeology


I teach in a Christian School where only men teach the Bible classes. I have offered several electives over the past 7 years on books of the Bible and rarely have I had a female student in the class. It may be that females are getting the idea that the Bible is a "guy thing." On the other hand, my course on "Women of the Bible" which I teach at a women's college has had only one male student in three years. Perhaps women are more likely to engage if the course of study is tailored to them. This is true certainly true for Biblical Anthropology, the field I have been pioneering for 30+ years.

Reading God's Second Book


Delicate

Hello readers. I’m Karen McReynolds, a professor of science at Hope International University in sunny Orange County, California. Hope is a small Christian university, so small that I should really say “the” professor of science. (Well, we do have a couple of adjuncts this semester.) We offer upper division courses only through our contract program with the Cal State campus across the street, so my full time responsibility here is science for the non-major student meeting general education requirements. I teach biology, environmental science and earth science – quite a broad spectrum for the college level. I like the variety of courses though. My childhood home in rural central California nurtured in me a love for birds and sky and wetlands, framed by the distant Sierra Nevada. Our parents wisely let us kids roam, and even encouraged me by supplying my own Peterson’s Field Guide to Western Birds, the adult version, when I was eight. Now I do my best to encourage my students to marvel, as I do, at God’s Second Book: the Book of Nature.

I like to tell the students the first day of class that my role model is Ms. Frizzle. It’s always good for a laugh. I hope to share with you occasionally some reflections on nature, teaching, and the intersection of the two, in the indefatigable spirit of Ms. Frizzle.

Some years ago, my husband, my father and I were working as a team on a biological survey of a large property in the northern Sierra Nevada. This was rather like having our cake and eating it too. For three seasons in a row, our teaching schedules permitted several weeks in the summer at 6400 feet, making observations and collecting data on natural history while the heat of the San Joaquin Valley passed us right on by. We found time to jump in the lake at the end of each day, and slept outside on tent platforms under the wide open, star-laden sky each night.

One afternoon I took a path that was new to me and came across the remains of a fawn nestled in a hollow of pine duff. More accurately, it was a fragment of the remains of a fawn: most of the rib cage, a bit of the spine, and the right foreleg of a very small deer. It must have been out in the woods for a while, because the bones were nearly white and free of flesh. The tiny hoof at the end of the leg was graceful and dainty, quite miniature in comparison to the numerous hoof prints of mule deer I had seen through the weeks of this project. It had clearly been dragged in from somewhere else, as there was no sign of any of the rest of the body, but the way it was settled in its spot so tidily suggested that it had seen some seasons pass in that location. The doe that returned to her baby’s ill-chosen hiding spot had made her fateful discovery some time ago.

. . . . . . . . 


I am a rather clunky woman, heavy of foot and inclined to drop things. Perhaps in accordance with this, I frequently need to be whacked over the head by something before I will notice it. I have developed reasonably astute observation skills after years of field experiences and practice, but it has taken intentional effort and is not my default character. Perhaps this is why my discovery delighted me more than it made me sad. It made me realize that if such a delicate specimen could remain, there is hope that I too might leave something behind that could speak of life in the midst of death.

There isn’t much about me that is delicate. That is not a word I would think to apply to myself and indeed it is an adjective I seldom use at all. It certainly would not seem to be an appropriate term to describe skeletal remains. But nature subsists on inappropriate truth. In all its grisly detail, the evidence I encountered that day of the early death of a young deer was indeed quite strikingly beautiful and delicate.
