Another Solar System - How Cool Is That?

Exoplanet discovery: What does Nasa's announcement mean- and should we be excited about TRAPPIST-1?

Google has marked the Earth-shattering discovery with a Doodle, featuring the seven planets squeezing into view on the earth's telescope.

What is TRAPPIST-1?

TRAPPIST-1 stands for Transiting Planets and Planetesimals Small Telescope. The discovery is a small, dim star in the constellation Aquarius, less than 40 light-years from Earth, or 235 trillion miles away, according to Nasa and the Belgian-led research team who announced its discovery on Wednesday. 
Seven planets circle Trappist-1, with orbits ranging from one and a half to 20 days. If Trappist-1 were our sun, all these planets would fit inside the orbit of Mercury. That's how close they are to their star and why their orbits are so short. The planets have no real names. They're only known by letters, "b" through "h." The letter "A" refers to the star itself.

Can this newly discovered solar system support life?

Six of TRAPPIST-1's "exoplanets" lie in a temperate zone where surface temperatures range from zero to 100C.
Of these, at least three are thought to be capable of having watery oceans, greatly increasing the likelihood of life.
No other star system known contains such a large number of Earth-sized and probably rocky planets.
All are about the same size as Earth or Venus, or slightly smaller. Because the parent star is so dim, the planets are warmed gently despite having orbits much smaller than that of Mercury, the planet closest to the sun.
Scientists said they need to study the atmospheres before determining whether these rocky, terrestrial planets could support some sort of life. 

What do the planets and solar system look like?

As well as being in tight orbits, the TRAPPIST-1 planets are unusually close to one another, conjuring an image straight out of science fiction.
If Trappist-1 were our sun, all seven planets would be inside Mercury's orbit. Mercury is the innermost planet of our own solar system.
From the viewpoint of someone standing on the surface of one of the planets, some of the other worlds would appear larger than the moon in the Earth's sky.
Gazing up, it would be possible to see the geological features, oceans and clouds of your planetary neighbours.
The ultracool star at the heart of this system would shine 200 times dimmer than our sun, a perpetual twilight as we know it. And the star would glow red - maybe salmon-colored, the researchers speculate.

Why all the excitement?

Three of TRAPPIST-1's "exoplanets" are smack dab in the so-called habitable zone, also known as the Goldilocks zone, where conditions are just right for watery oceans - not too much and not too little stellar energy - greatly increasing the likelihood of life.


No other star system known contains such a large number of Earth-sized and probably rocky planets.
All are about the same size as Earth or Venus, or slightly smaller. Because the parent star is so dim, the planets are warmed gently despite having orbits much smaller than that of Mercury, the planet closest to the sun.
Scientists said they need to study the atmospheres before determining whether these rocky, terrestrial planets could support some sort of life. 
But just because a planet is in this sweet spot, doesn't mean life exists or ever did. 
How did they find out about TRAPPIST-1?
What does TRAPPIST-1 stand for?What is an exoplanet anyway?
The discovery, reported in the journal Nature, was made by astronomers using Nasa's exoplanet-hunting Spitzer Space Telescope.
The telescope operates at the infrared wavelengths which glow brightest from TRAPPIST-1, and can detect the tiny dimming that occurs when a passing or "transiting" planet blocks out light from its star.
Spitzer's data allowed the team to measure precisely the sizes of the seven planets and estimate the masses and densities of six of them.
The Spitzer was launched in 2003, and was never meant to continue in space for this long but the telescope is still making discoveries beyond what was imagined. It follows the earth's orbit around the sun, but travels slightly slower, so over time it gets further away from the earth. It is now in its "final" phase, which lasts until 2018.
Transiting Planets and Planetesimals Small Telescope
An exoplanet is any planet that is outside of our solar system - ie anything that is not orbiting our star. The first exoplanet was discovered in 1988, but over 3,500 have been discovered since then.
Only a tiny fraction of these have been deemed capable of supporting life in any way. Oceans and closeness to a star are two factors that scientists take into account.

A Great Website Discovery


I discovered a new tool today. It's called AutoMotivator and I think it is pretty nifty. The site helps you make posters that can be used for many different venues (such as for blogs). You can use a random picture from their site, choose a picture from their site, choose a picture from your computer, or search the web for the perfect picture. Once you have the perfect image for your needs you are asked to create a title and to add text for your poster, if desired. The next step is to preview your poster and, if acceptable, choose where to save it. There are choices such as Flickr, imgur, or your computer. There are also links to Facebook, Twitter, Pinterest, and numerous other apps as well as options to print or email your creation. You can also have your poster printed for a price. The cost is $9.95 for a regular size poster or $19.95 for large posters.

The above poster was created using one of the site's photos and their title and a version of one of their ideas for the text. It was a quick and easy venture and one that I am sure I will use over and over. 

If you are into posters or like the idea of creating poster-like additions to your personal sites (including Facebook), I suggest trying this site. I don't think they will disappoint.

The Library Bulletin Board


One of the many jobs of an assistant librarian is creating and maintaining the library bulletin board. It is a good idea to keep a file with lots of ideas so that a beautiful bulletin board, an interesting bulletin board, or an informative bulletin board is very close at hand. 

Speaking of hands, using a visual cue and a play on words is a good way to create an eye catching bulletin board. This particular board has the turkey's tail feathers made of colorful hands with the caption, "Get Your Hands on a Good Book" to accompany them. 


This particular bulletin board uses the idea of an apple peeling to go with the caption, "Reading Just for the Fun of it is so A * Peel * Ing." Bright and colorful apples capture the eye. The dividers between the A and Peel and the Peel and Ing are apples in the process of being peeled. Simple touches can make a big difference in the a * peel of a board. 

Library bulletin boards should also promote reading. While libraries promote good study habits, offer research assistance, give access to computers and environments conducive to studying, and offer guidance and help in classroom assignments, the main nature of a library is to provide materials that will nurture the joy of reading.

The building also houses a two-story “cyber cafe,” with 24-hour study and dining space.

Meanwhile, the University of Notre Dame is spending millions to renovate 414,000 square feet of its 14-story Hesburgh Library, with the goal of making the space an inviting destination for intellectual work. Phase I, which will cost an estimated $7 million, aims to bring more light and openness to the first two floors, while one-third of the library’s books have been moved to an off-site location.

Giving up the library’s prime real estate on campus was never a serious consideration, university librarian Diane Parr Walker says. “The library probably serves a greater number and diversity of constituents than just about any other group on campus. I think it’s fair to say the academic library is still the academic core of the institution.”

Designing for flexibility

Increasing reliance on digital resources is an obvious factor causing libraries to evolve. But changes in pedagogy are just as much—if not more—of a factor. The emphasis on active, student-centered learning has compelled libraries to create more adaptable spaces for students to work, both independently and in groups of all sizes.

Grand Valley State University in Michigan made room for these spaces by moving 600,000 of its print works into an automated storage and retrieval system. With these volumes stored beneath the library, 90 percent of the book footprint could be eliminated.

At first, the building was divided into what library dean Lee VanOrsdel calls a “contemplative side” and a “collaborative side,” but it was quickly determined that this didn’t work.

“Students’ and researchers’ behaviors change throughout the day, week and semester,” VanOrsdel says. “There is no way to build a building or populate it with furniture to meet all those needs.”

To plan for what she calls “extreme flexibility,” Grand Valley State acquired 29 different types of seating through Steelcase Education that can be moved easily around the library so students can work alone or in groups. “Students have taken ownership of the building,” Van Orsdel says. “They’re here all hours of the day moving whiteboards and chairs on the elevator, and we don’t stop them.”

This flexibility also applies to computer labs, where students expect a variety of options beyond row after row of desktop terminals. The University of Southern Maine offers high-top tables where students can use laptops, and smaller stations with two or three computers where groups can work together. “We’re not adding or eliminating computers, but using them differently,” says librarian David Nutty.

An increasing number of institutions want expanded computer space for competency-based, self-directed learning supported by tutors, says Julie Todaro, president of the American Library Association and dean of library services at Austin Community College in Texas.

Libraries are now creating large alternative classroom environments where students might work independently or in tablet chairs at one end, with faculty teaching a class at the other.

As for today’s technology expectations: “It needs to run throughout the building,” Todaro says. “There’s a push toward wireless, of course, but libraries also need to go back in and make floors and walls electrified so people can sit anywhere and charge their technology.”

Cross-disciplinary guidance

An increased pedagogical emphasis on collaboration means more than just working on a group project for one class. Libraries now focus on supporting “cross-disciplinary discovery,” Todaro says. In Todaro’s library at Austin Community College, students in the “BatLab” makerspace create everything from robots and animation to music made through the electric conductivity of vegetables using the small but powerful Raspberry Pi computer.

At Notre Dame, this type of work often takes place in the library’s Center for Digital Scholarship, which features a sound studio, 3D printing service, high-tech classrooms and a digital research lab.

In a group project space, students recently completed an urban planning project with the city of South Bend. Supported by library faculty—including two graphic information specialists—these students created geocoded maps based on photos of different neighborhoods taken with their mobile phones.

Providing the right technology and expertise is key to fostering such projects, says Notre Dame’s Walker. As library faculty and staff have retired, their positions have been redesigned to include Ph.D.s or postdocs in various sciences and specialties—particularly those who can help students and faculty use the high-end technology that draws them to the library in the first place, she says.

But even simple technology can make a difference, Todaro points out. At Austin, tables equipped with desktop paper drawing pads that students can write on and move wherever they want are among the most popular features.

What matters most is creating an inviting space for collaboration, says Nutty of the U of Southern Maine. The amount of bells and whistles you add depends on what resources you have available.

Roving research assistance

Libraries also have an opportunity to help students develop soft skills essential for the workforce that may not be taught in the classroom, says VanOrsdel at Grand Valley State. Its library also hosts an oral presentation lab to reinforce an increased emphasis on public speaking in the classroom and workplace, for example.

It’s now common for college libraries to partner with other academic services to house writing centers, math tutoring and technology help desks, as well.

At Drexel University in Philadelphia, preparing the next generation of students means “recognizing that data is everywhere,” says dean of libraries Danuta Nitecki. Her library, which she likes to think of as “information exploratorium,” offers a Data Visualization Zone, where students from different disciplines can experiment with numbers to track changes in plant life or map out census information.

Despite the need to accommodate new pedagogical demands, fundamental research assistance—which now includes digital literacy—is still a key function of the library, says Tom Rink, president of the international Special Libraries Association’s board of directors.

“You have students battling information overload like never before,” Rink says. “Lacking even basic information skills, many are settling for information that is quick and easy to find while having little or no concern over the relevance or evaluative quality.”

It is no longer enough to have a stationary reference desk and expect students to approach it with questions. The focus is now on offering “roving reference” assistance throughout the library to provide guidance and expertise as needed, right where users are working.

Physical library’s future

Is a future without a physical campus library possible? Meeting students where they’re working, in some cases, means meeting them online. The library has an important virtual role to play, especially at universities or schools that offer many hybrid or exclusively online courses, Rink says.

Under those circumstances, the library still offers e-books, electronic journals, open access materials and reference services, without having to occupy a physical space on campus.

Nitecki of Drexel says the services that libraries provide will always be necessary—but might take different forms. Drexel, which offers a great deal of online and hybrid courses, has a small but frequently used library.

“The expertise might be able to go out to wherever the student is working,” Nitecki says. Students crave a space where they can work alone, together—or alone but in the presence of others. “It might not have to be a physical space called the library,” she says.

Although 21st century libraries certainly look much different than the libraries in the past, many still emphasize the importance of its traditional product—the book. Notre Dame’s library renovation plans include a grand reading room, and special print collections are more visible in exhibit areas.

Salisbury University will devote 50 percent more space to books. Hardy points to the fact that more books are being printed today than ever before. Also, licensing electronic materials can be quite costly for a library and, according to a 2013 American University study, 92 percent of U.S. college students prefer print, she notes.

And while libraries have now become bustling hubs of active learning, there is still a need for quiet: Todaro says she and her staff at Austin distribute earplugs and encourage students to bring headsets, especially during peak study times in the semester.

And as Walker of Notre Dame explains, her library’s smaller, temporary reading room is “amazingly popular” and “self-policing”—even she gets shushed if she enters making too much noise.

Libraries of the future...today.
         

Book delivery drone

To get the book from a library, you can either go and find it, or you can let it find you.
The future belongs to unmanned flying machines, and just like Amazon drones can deliver the goods to customers, libraries could deliver the books to patrons.
Library drone is not even the close future. It’s already happening. Australian start-up Flirtey has teamed up with a book rental service Zookal to create – the first in the world – textbook delivery system.
The system is using hexacopters, drones with six rotors, to deliver ordered textbooks. Now, the smart thing is that the drone can find you by the location of your smartphone, so there is no need to give a fixed address.
Just imagine. You are sitting in a reading room of the New York Public Library, in the middle of writing an essay, and want to get another book. Stay where you are, and use the app to order a book. The drone will come, just like this one. Pull out the book from the box, and put the one or ones you don’t need any longer. The drone will place them where they belong.
I would personally add an option to deliver latte from a library cafeteria.
