NASA to let public help in hunt for distant planets

Posted on by

GREENBELT, Md., Jan. 31 (UPI) -- NASA says the public is being invited to help search for embryonic planetary systems hidden among data from an agency spacecraft mission.

Through a new website, DiskDetective.org, citizen scientists can sift through data collected by NASA's Wide-field Infrared Survey Explorer (WISE) mission, the agency reported Thursday.

"Through Disk Detective, volunteers will help the astronomical community discover new planetary nurseries that will become future targets for NASA's Hubble Space Telescope and its successor, the James Webb Space Telescope," said James Garvin, the chief scientist for NASA Goddard's Sciences and Exploration Directorate.

WISE, designed to survey the entire sky at infrared wavelengths, completed two scans of the entire sky from its orbit around Earth between 2010 and 2011.

While there may be thousands of nascent solar systems in the WISE data, the only way to know for sure is to inspect each source by eye, a monumental challenge that led NASA turn to a crowdsourcing solution.

The space agency has teamed up with Zooniverse, a collaboration of scientists, software developers and educators who collectively develop and manage citizen science projects on the Internet.

Volunteers will be able to look at WISE images and classify objects based on simple criteria, such as whether the image is round or includes multiple objects. The information will help astronomers assess which sources should be explored in greater detail in the future.

"Disk Detective's simple and engaging interface allows volunteers from all over the world to participate in cutting-edge astronomy research that wouldn't even be possible without their efforts," said Laura Whyte, director of citizen science at Adler Planetarium in Chicago, Ill., and a founding partner of the Zooniverse collaboration.

NASA shows 60 years of climate change in 15 seconds

A new NASA video shows changes to temperature maps of the Earth from 1950 all the way to 2013.

When you put all the data together, it becomes pretty hard to deny that global temperatures are slowly but surely rising.

A new video released by NASA shows just over six decades of global temperatures, making it pretty clear that the world is getting warmer. In fact, according to NASA data, 9 of the 10 warmest years on record have occurred since the year 2000 (the other was 1998), with the hottest years being 2010 and 2005.

According to the NASA Goddard Institute for Space Studies (GISS), which analyzes global surface temperatures, the average temperature for 2013 was 14.6 degrees Celsius (58.28 degrees Fahrenheit), which is 0.6 Celsius degrees higher than the mid-20th-century baseline. The average global temperature has risen 0.8 degrees since 1880.

Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change," said GISS climatologist Gavin Schmidt. "While one year or one season can be affected by random weather events, this analysis shows the necessity for continued, long-term monitoring."

GISS attributes the rise in global temperatures to the increase in greenhouse gas levels, driven by man-made emissions, in the Earth's atmosphere. It notes that while successive years may not necessarily be warmer sequentially, overall trends will see a continued rise. The level of carbon dioxide in the atmosphere -- over 400 parts per million -- is higher now than at any time in the last 800,000 years. In 1880, it was just 285 parts per million.

NASA-Sponsored ‘Disk Detective’ Lets Public Search for New Planetary Nurseries

Posted on by

NASA is inviting the public to help astronomers discover embryonic planetary systems hidden among data from the agency's Wide-field Infrared Survey Explorer (WISE) mission through a new website, DiskDetective.org.

Disk Detective is NASA's largest crowdsourcing project whose primary goal is to produce publishable scientific results. It exemplifies a new commitment to crowdsourcing and open data by the United States government.

"Through Disk Detective, volunteers will help the astronomical community discover new planetary nurseries that will become future targets for NASA's Hubble Space Telescope and its successor, the James Webb Space Telescope," said James Garvin, the chief scientist for NASA Goddard's Sciences and Exploration Directorate.

WISE was designed to survey the entire sky at infrared wavelengths. From a perch in Earth orbit, the spacecraft completed two scans of the entire sky between 2010 and 2011. It took detailed measurements on more than 745 million objects, representing the most comprehensive survey of the sky at mid-infrared wavelengths currently available.

Astronomers have used computers to search this haystack of data for planet-forming environments and narrowed the field to about a half-million sources that shine brightly in the infrared, indicating they may be "needles": dust-rich disks that are absorbing their star's light and reradiating it as heat.

"Planets form and grow within disks of gas, dust and icy grains that surround young stars, but many details about the process still elude us," said Marc Kuchner, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md. "We need more examples of planet-forming habitats to better understand how planets grow and mature."

But galaxies, interstellar dust clouds, and asteroids also glow in the infrared, which stymies automated efforts to identify planetary habitats. There may be thousands of nascent solar systems in the WISE data, but the only way to know for sure is to inspect each source by eye, which poses a monumental challenge.

Public participation in scientific research is a type of crowdsourcing known as citizen science. It allows the public to make critical contributions to the fields of science, technology, engineering and mathematics by collecting, analyzing and sharing a wide range of data. NASA uses citizen science to engage the public in problem-solving.

Kuchner recognized the spotting of planetary nurseries as a perfect opportunity for crowdsourcing. He arranged for NASA to team up with the Zooniverse, a collaboration of scientists, software developers and educators who collectively develop and manage citizen science projects on the Internet. The result of their combined effort is Disk Detective.
