You Too Can Discover Exo-Planets, Supernovae, Galaxies And More on Zooniverse

Zooniverse is a citizen science portal that offers enthusiastic members of the public to participate in scientific research projects – projects that requires immense amount of man hours and which cannot be automated. Zooniverse was originally started in 2007 as Galaxy Zoo (previously) in which the public was enlisted to classify galaxies in images from the Sloan Digital Sky Survey. Since then it added others such as Milky Way project, Galaxy Zoo Hubble, Galaxy Zoo Supernovae, and Solar StormWatch among others.


We have quite a large number of space telescopes, both terrestrial and orbiting, and probes that take hundreds and thousands of images of the sky and send them to earth for astronomers to study. Each of these images consist of millions of galaxies that must be observed and analyzed minutely for specific features. This is a giant task. The vast range of features, shapes, brightness and colors that these galaxies and stars can take makes the job even trickier and this is something that cannot be offloaded to a computer.

So the guys hit on the idea of crowd sourcing. The idea was to distribute the images to members of the public and, after a short tutorial, ask them to do the classification instead. By asking lots of different people to classify the same image, researchers found that the average score was just as good as the classification given by professional astronomers. And thus Galaxy Zoo was born.

Today, Galaxy Zoo, which has since evolved into Zooniverse, engages in different projects based on the core principle of participation of the public. These include:

  • Galaxy Zoo Hubble (involves classifying hundreds of thousands of galaxies drawn from NASA's Hubble Space Telescope archive. It includes galaxies with 'blue clumps' that may represent a stage in the maturing of galaxies into modern forms.)
  • Galaxy Zoo Supernovae (spot exploding stars by comparing images of the same region of the sky taken at different times)
  • Galaxy Zoo Mergers (understanding cosmic mergers)
  • Moon Zoo (explore the Moon in unprecedented detail and help classify craters and other features)
  • Old Weather (involves recovering worldwide weather observations made by Royal Navy ships around the time of World War I)
  • Solarstorm Watch (spot explosions on the Sun and track them across space to Earth)
  • Planet Hunters (identifying extrasolar planets by detecting brightness variation of distant stars)
  • The Milky Way Project (study images of the Milky Way and flag features such as gas bubbles, knots of gas and dust and star clusters)

To take part in any of these projects you have to signup and take short tutorial. The tutorials are usually brief and to-the-point and teaches you exactly what to look for in the images. Don’t worry if you don’t understand the science behind it, though it is a very good idea to get educated on the subject.

Zooniverse gives you an exceptional opportunity to take part in some of the most exciting and fascinating scientific undertaking of our time – the Kepler mission and the Hubble telescope forever unraveling the mysteries of deep space. You don’t need a degree in astronomy, nor a telescope. Just pure passion, the willingness to learn and lots of patience and, of course, free time.

In less than four years, Zooniverse has grown to 400,000 members and together they have supplied over 100 million classifications. Zooniverse is now a powerful force in astronomy. Why not be a part of it?

Don’t have time to get involved? There are others ways to help like offering your computer’s idle time to science research.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.

Diagram 101: Different Types of Diagrams and When To Use Them

Diagrams are a great way to visualize information and convey meaning. The problem is that there’s too many different types of diagrams, so it can be hard to know which ones you should use in any given situation. To help you out, we’ve created this diagram that lays out the 7 most common types of diagrams and when they’re best used:
