Are They Just Right? The Discovery of the TRAPPIST-1 Planetary System and Their ‘Goldilocks’ Potential
In the past several months science educators teaching astronomy and space exploration probably haven’t needed a lot to motivate science students who are endlessly fascinated with the possibility of life outside our own planet. The recent discovery of seven planets around TRAPPIST-1 (a star named for the Transiting Planets and Planetesimals Small Telescope in Chile) has provided teachers new seeds to plant into the imagination of young minds interested in exoplanetary discovery. eLibrary can help feed that imagination with loads of resources.
In May 2016 researchers in Chile reported in the journal Nature the discovery of three planets with sizes and temperatures similar to Venus and Earth orbiting around an ultra-cool dwarf star just 40 light-years away in the Aquarius constellation. Earlier this year NASA’s Spitzer Space Telescope, along with the Very Large Telescope Array at Paranal in Chile, confirmed two of those planets, and then found five more exoplanets. Of the seven, three are presently believed to fall within the habitability zone (the ‘goldilocks’ zone), that area around a star in which rocky planets may hold liquid water and harbor life.
TRAPPIST-1, the star which these planets orbit, is classified as an ultra-cool dwarf. The star is so cool that water in liquid form could exist on planets that are even closer in orbit than Mercury is to our sun. In the years to come, if further observations reveal oxygen in any of the planet’s atmosphere, which could point to photosynthesis of plants, there is a good probability life can exist on these planets.
eLibrary has recent news information on this discovery as well as Research Topics on exoplanets, habitable planets, and general information on astronomy, cosmology, and space exploration that can help your students dive deeper into the questions of life existing elsewhere in our galaxy and beyond.
Here are some things scientists know thus far about TRAPPIST-1 and its planets:
- All seven of the TRAPPIST-1 planet’s orbit is closer than Mercury’s orbit around our sun.
- TRAPPIST-1 is much cooler and redder than the sun, and only slightly larger than Jupiter, which is about a tenth of the size of the sun.
- Because the planets are so close to TRAPPIST-1, all seven planets appear to be in a gravitational lock. That is, one side of each planet permanently faces the star, just as our moon is gravitationally locked and we only see one side of it.
- One year on the closest planet orbiting TRAPPIST-1 is equal to just 1.5 earth days. The farthest planet’s yearly orbit is equal to 18.8 earth days.
- If you were standing on one of the planets, each of the other planets would appear prominently in the sky, and at times appearing much larger than the moon does in our sky.
- TRAPPIST-1 is a mere 40 light-years away. In layman’s terms, that’s still 235 trillion miles away.
One of the biggest challenges for teachers is helping students overcome the fear of writing the research paper. Students will invariably ask: “What should I write about? How do I get started? Where do I find the information for my subject? It’s due when?!” Not only is it a challenge for students to get started and take the time to research their subject thoroughly, but also be under pressure with a deadline to finish it. It’s up to the teacher to help students navigate these obstacles and be successful with their research papers. ProQuest may be able to help you in this endeavor.
ProQuest’s eLibrary can help you guide your students through the research process from beginning to end with its Research Topic on Writing a Research Paper. There is a section on the elements and processes of writing with articles on critical thinking skills, note-taking, evaluating sources, and revising and editing their papers, along with other helpful articles.
One aspect of writing a research paper is using and citing reliable information sources. In the past several months fake news has become a topic of interest in national politics, but it can be a great teaching tool as part of your research instruction by showing students the difference of what is and is not reliable information. eLibrary also has a Research Topic on Fake News, with articles about the characteristics of fake news, evaluating sources, and how to recognize fake news when it is presented.
Another source for helping you guide your students through the research process is the ProQuest Research Companion, a self-guided tool that assists them in doing more effective research and helps you teach the fundamentals of finding and evaluating useful, reliable information. Research Companion can help your students wade through what is often an overwhelming amount of information by guiding their research effort. It is comprised of ten Learning Modules and five interactive tools arranged to automate the stages of the research process.
Research can be hard for for first-time researchers, and even seasoned students can find it difficult wading through the process of gathering information, drafting, revising, editing, and finalizing their research papers. But maybe it can be less painful with a little help from ProQuest.
Today many educators, including math teachers, who are looking for ways to engage students’ minds can sweeten the learning curve by celebrating March 14 (3.14), Pi Day. Just like pi, there are infinite possibilities in motivating students in learning this mathematical constant (as long as they get to eat the examples, of course). Making pies, cookies, cakes, and other circular foods (don’t forget about pizza!) of different sizes can all play a part in motivating students in discovering the wonders of pi.
Students can double down on the learning experience because today is also the birthday of the world’s most celebrated scientist, Albert Einstein. And you can bet that Einstein was no stranger to pi. March 14 is a wonderful opportunity to enlighten your students about the endless fascination to the mathematical constant pi (3.14), and at the same time teach them about the extraordinary life of one of our greatest scientists. Be sure to click on the pi and Albert Einstein images below to open ProQuest Research Topics to learn more on both, or search eLibrary here.
Here are some facts about both Pi and Albert Einstein:
- Pi is the ratio of the circumference of a circle to its diameter (circumference divided by diameter).
- Pi is an irrational number meaning that it cannot be written as a fraction and therefore has to be expressed as an infinite non-repeating decimal.
- The Babylonians first calculated the area of a circle around 2,000 B.C.
- Archimedes was the first to use the calculation of pi. He roughly calculated the area of a circle using the Pythagorean Theorem to find the areas of two regular polygons.
- The earliest adoption of the Greek symbol for pi (π) was by William Jones.
- The closest fraction representing pi is 22/7.
- English singer-songwriter Kate Bush has a song called “Pi” in which she sings the number’s first 100 decimal places.
- Einstein dropped out of high school and failed his first college entrance exam.
- Adolph Hitler considered Einstein enemy number one. After Hitler’s ascendancy to Chancellor of Germany, he had his house sacked while he was in California. Einstein never returned to Germany.
- Family members say Albert didn’t start to speak until the age of four.
- Einstein was a member of the NAACP. When Einstein arrived in America he was shocked by how African Americans were treated. Before he moved to America he frequently corresponded with civil rights leader and founder of the NAACP, W.E.B. Dubois.
- In less than one year in 1905, Einstein, an unknown scientist at the time, wrote and published his Annu mirabilis (The Miracle Year) papers. In these papers, he redefined the laws of physics and altered our views on space, time, mass, and energy, and laid the foundation for all modern physics we know today.
- After Einstein’s death, Princeton University pathologist Thomas Stoltz Harvey performed Einstein’s autopsy. He removed his brain for research purposes but strangely kept it at his house for over 40 years. Some time later in the 1990s, he took the brain on a strange trip across America in the trunk of a Buick Skylark.
It’s time to spring ahead! At 2:00 a.m. on Sunday, March 12, most of us in the United States—unless we live in Arizona or Hawaii—will move our clocks forward one hour. While many people appreciate the extra hour of sunlight at the end of the day, just as many probably dread heading to work and school in the dark before sunrise.
Daylight Saving Time was first used to conserve energy during World War I. Today, more than 70 countries use Daylight Saving Time in at least part of their country. Researchers may be surprised to learn that Daylight Saving Time has such a confusing and complicated history in the U.S. and that there are many arguments for and against its use. Those in favor of DST argue that it saves energy, encourages more physical activity, and reduces accidents and crime. Opponents of DST say that it is economically disruptive, particularly to farmers, and dangerous for children who have to walk to morning bus stops in the dark.
Here is a brief timeline of legislation regarding time zones and Daylight Saving in the U.S.:
1784: Benjamin Franklin suggests the concept of daylight saving as a way to use fewer candles.
1883: American and Canadian railroads establish national time zones to end the confusion of dealing with thousands of different local times.
March 19, 1918: Congress enacts a law to establish standard time zones and sets summer Daylight Saving Time to begin on March 31, 1918.
1919: The Daylight Saving Time law is repealed due to its unpopularity. It remains a local option and is continued in a few states and in some cities.
1942-1943: President Franklin Roosevelt institutes year-round Daylight Saving Time, also called “War Time”, during World War II.
1945-1966: There is no federal law regarding Daylight Saving Time so states and cities are free to choose when it begins and ends. This becomes a source of confusion, especially for the broadcasting industry, railways, airlines, and bus companies.
1966: President Lyndon Johnson signs the Uniform Time Act of 1966 which calls for Daylight Saving Time to begin on the last Sunday of April and to end on the last Sunday of October. The law allows any state that doesn’t want to use Daylight Saving Time to pass a state law exempting themselves.
Jan. 4, 1974: President Richard Nixon signs the Emergency Daylight Saving Time Energy Conservation Act of 1973 in an effort to conserve energy during the 1973 Arab oil embargo. Daylight Saving Time begins on Jan. 6, 1974 and ends on Oct. 27, 1974. Daylight Saving Time then resumes on Feb. 23, 1975, and ends on Oct. 26, 1975.
1986: Congress passes a law declaring that Daylight Saving Time in the U.S. begins at 2:00 a.m. on the first Sunday of April and ends at 2:00 a.m. on the last Sunday of October.
2005: The Energy Policy Act of 2005 extends Daylight Saving Time in the U.S. beginning in 2007.
2007: The Energy Policy Act of 2005 goes into effect with Daylight Saving Time beginning at 2:00 a.m. on the second Sunday of March and ending at 2:00 a.m. on the first Sunday of November.

It is groundhog day again–it seems like the last one was only yesterday. A few years ago, a colleague did a great post on Groundhog Day itself, so I won’t repeat that here, but I started thinking about rodents (the groundhog is one). Here are a few rodent morsels on which to chew. (Ew, that didn’t sound right.):
–Rodents are from the order Rodentia, and they account for around half of all mammal species. (Note about this link: This takes you to the subject browse area of eLibrary. Anything with a yellow star next to it includes a Research Topic page.)
-The word “rodent” comes from Latin word meaning “to gnaw.” This makes sense, considering that their large front teeth and gnawing habit are probably the things that most define them in our minds. They gnaw because those front teeth grow continuously and failure to wear them down would result in death from starvation or impalement of the skull.
-The smallest rodent is the pygmy jerboa, only about an inch long. The largest rodent in the world, currently, is the capybara, but its extinct cousin Josephoartigasia monesi was the largest ever, measuring in at eight feet. And just for the awwwww-factor, here is a picture of two cute baby capybaras with their mother.
-Among the common animals that are mistaken for rodents but are not, are the rabbit and the opossum, which is a marsupial. (Speaking of marsupials, here is a crazy one: the Tasmanian wolf. It became extinct in the 1930s, and scientists had hoped to bring it back through cloning. He sure doesn’t look like a kangaroo.)
-Most rodent species are highly social. In an interesting experiment, a researcher showed that rats show empathy by working to free others from cages.
-While they were once killed in huge numbers for their pelts and to eliminate them as pests, beavers, the second-largest rodents, are becoming respected for the benefits they provide, including erosion prevention, improvement of fish and wildlife habitat and soil enrichment.
-On the other hand, some rodents can carry diseases deadly to humans, including plague and hantavirus.

This Friday the 58th U.S. Presidential Inauguration will take place at our nation’s capital when Donald Trump will be sworn in as the 45th president. Here are some interesting facts about the history of the ceremony and related events that you may not know.
In his second inaugural address in 1793, George Washington spoke just 135 words, the shortest inaugural address ever given. Juxtapose that with the speech William Henry Harrison gave in 1841. Harrison delivered an 8,495-word speech lasting one hour and forty five minutes in the middle of a snowstorm without a hat or coat. Harrison’s presidency also is known as the shortest. He died a month after the inauguration from complications of pneumonia. Many believed that the long exposure to the elements during his lengthy speech contributed to his death.
The first inaugural ball was held the night after James Madison was sworn into office. A ticket to the ball? It cost just $4, which today would be worth around $60. Tickets to Donald Trump’s inaugural ball are estimated to range from $25,000 to $1,000,000.
As part of Abraham Lincoln’s 1865 presidential inauguration, African Americans were allowed to participate in the inaugural parade for the first time ever.
Even though much of this past election was downright rancorous, Barack Obama and Hillary and Bill Clinton are expected to be in attendance at Donald Trump’s inaugural swearing in. At Andrew Jackson‘s first inauguration in 1829, outgoing president John Quincy Adams did not attend. The bitter campaign for president left a bad taste in both men. Jackson blamed offensive verbal attacks by Adams and his supporters for the death of his wife.
The first inauguration of Barack Obama in 2009 smashed the record for attendance (estimated at 1.8 million) previously held by Lyndon B. Johnson’s second inauguration attendance of 1.2 million in 1965.
Official Day of Inauguration:
Most presidential inaugurations from 1797 to 1933 (John Adams to Franklin Delano Roosevelt) were held on March 4. Since 1933, with a few exceptions, the ceremony has been held on January 20. One reason the inaugurations were held on March 4, prior to 1933, was to give precincts and states time to hand count and deliver all the votes, all with little technological help. The extended period between the election and the day of inauguration also meant an extended lame-duck session in Congress. So in 1933, with a more modern communications and systems of voting, Congress passed the 20th Amendment to establish the new inauguration day of January 20.
When January 20 falls on a Sunday, the official oath is still given on that day, but the ceremony, and another ceremonial oath, takes place on Monday the following day.
Location of the Inauguration:
Thomas Jefferson was the first president inaugurated in Washington, D.C. Jefferson was also the first to be inaugurated at the Capitol building in Washington. Most of the inaugurations were held outside on the eastern front of the building until after Jimmy Carter‘s presidency. Since 1981, beginning with Ronald Reagan‘s presidency, most ceremonies have been held on the spacious west side to accommodate more spectators.
There have been some exceptions to the standard location over the years. For Franklin D. Roosevelt’s final inauguration the ceremony was held in the White House. Roosevelt would die three months later, and Harry Truman would be sworn into office in the Cabinet Room of the White House.
The weather during Ronald Reagan’s second inauguration was so cold (minus 7 degrees) the event had to be moved indoors to the Capitol Rotunda, which was very much unlike his first inauguration in 1981 when the temperature hit 55 degrees.
Lyndon Baines Johnson owns the infamous title of being the only president ever to been sworn into office on board an airplane. Following John F. Kennedy‘s assassination in 1963, Johnson, accompanied by Jackie Kennedy and over 25 other dignitaries, squeezed into the stateroom of Air Force One. As the jet powered up, the oath of office was administered and Johnson became the 36th president. This event also marked the first and only time a woman has administered the presidential oath of office (Federal Judge Sarah T. Hughes).
