Eclipse in Africa: \'Ring of Fire\' eclipse wows stargazers

 

Stargazers in parts of Africa have been treated to a spectacular "ring of fire" in the sky as the sun was almost - but not completely - eclipsed.

An annular eclipse happens when the moon is farther away from the Earth than during a total eclipse.

The result is a bright circle of sunshine surrounding a dark, shadowy core.

The best views were seen in Tanzania, where the event lasted about three minutes.

The eclipse could also be viewed in parts of Gabon, Congo-Brazzaville, the Democratic Republic of Congo, Madagascar, and the French Indian Ocean island of La Reunion.

The moon does not move in a perfect circle around the earth - instead, its orbit is slightly elliptical. That means the distance of the moon varies between around 225,000-252,000 miles (362,000-405,555 km).

When the moon is farther away from the earth, it appears smaller - and does not totally cover the sun\'s disc during a total eclipse.

The result is also known as a "ring of fire" eclipse.

The next eclipse is due to take place in February 2017, and can be seen from parts of South America and Africa.

Embracing Open Data in Field-Driven Sciences

By Rebecca Fowler 10 March 2016

https://eos.org/opinions/embracing-open-data-in-field-driven-sciences

Climate change and the other complex issues facing our planet require the application of vast amounts of data,  information, and knowledge to be fully understood. No single scientist or organization has all of the data, tools, or capabilities to do this work; only by bringing diverse research communities together around shared data and information will these problems be addressed.

However, ecology, geology, and the other sciences that depend on field observations pose special challenges for data and sample sharing. These disciplines often rely on time-sensitive, perishable data and samples that are temporally and spatially unique: the observations of an ash plume evolving or the samples amassed during a research cruise to assess the impacts of an oil spill.

 

These challenges have caused field-driven sciences to be slow in making data accessible and reproducible. To keep research on the leading edge of discovery, data and sample sharing in the field sciences must evolve to become common practice.

Allowing data to be reused and research results to be replicated fosters innovation, high-quality research, and public trust in science.

Cell Phone Alerts Ring Out in Manhunt for NYC Bomber

It was a strange way to start the day. My work phone screamed out a noise that sounded like an air raid siren, flashing a message saying “WANTED.” Seconds later, my personal cell phone howled with the same message. The alerts, received by millions of others in and near New York City, announced the search for bombing suspect Ahmad Rahami, who is wanted in association with a bomb blast in Manhattan on Saturday night. The alerts also represented something else: the first digital manhunt of this scale to take place in the New York City.

While law enforcement has long used digital billboards, along with radio and TV stations, to alert the public about a suspect, this is the first time the modern equivalent of a “wanted” posted has appeared in everyone\'s pocket.

One strange feature about the alert is that it doesn\'t actually include a picture of Rahami, but instead instructs the recipient to “See media for pic.” It\'s not immediately clear why the phone carriers didn\'t transmit a picture with the alert. I\'ve reached out to AT&T and Verizon to find out if the decision not to send an image is related to technology, or is a policy decision.

The wanted message is the first of its kind, but cell phone carriers have issued similar alerts (complete with the siren noise) on a number of previous occasions. The most common of these is for “Amber Alerts,” which advise people about missing or abducted children. This kind of alert represents an unprecedented form of crowd-sourced law enforcement that could prove extremely effective, but may also raise questions about privacy and civil liberties if they become used on a regular basis.
