The Amazon rainforest and the Sahara desert seem utterly different. Yet NASA satellites have discovered a surprising connection that intimately links these two disparate parts of our planet.

NASA's NuSTAR Captures Possible 'Screams' from Zombie Stars

Peering into the heart of the Milky Way galaxy, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the "howls" of dead stars as they feed on stellar companions.

Indonesia Executes 8, Including 7 Foreigners, for Drug Convictions; One Wins Stay‏

Indonesia Executes 8, Including 7 Foreigners, for Drug Convictions; One Wins Stay
Defying international condemnation and rejecting 11th-hour pleas for clemency, the Indonesian government executed eight drug convicts after midnight on Wednesday, including seven foreigners.
But the execution of a ninth convict, scheduled to happen at the same time, was unexpectedly postponed at nearly the last minute, the Indonesia attorney general’s office said.
The eight executed prisoners from Australia, Brazil and Nigeria, along with one Indonesian, faced separate police firing squads at about 12:25 a.m. local time an execution site outside the gates of Pasir Putih prison on the island of Nusa Kambangan off the southern coast of Java, according to the attorney general’s office.

NASA Wants You … to Help Name Stuff on Pluto‏

April 21, 2015:  When NASA's New Horizons spacecraft flies by Pluto this July, the spacecraft's high-resolution cameras will spot many new landforms on the dwarf planet's unexplored surface.  There could be mountains, craters, rilles, valleys and, of course, the unknown.

They are all going to need names—and NASA wants you to help.

The public has until Friday, April 24 to help name new features on Pluto and its moons.  The naming campaign was announced in March, and now it is being extended because of widespread interest.

Click on the image, above, to nominate a name for newfound features on Pluto and its moon Charon.

The campaign not only expresses public interest in Pluto but also helps the busy New Horizons science team.

“[The team] will not have time to come up with names during the flyby," explains Jim Green, director of NASA’s Planetary Science Division at the agency’s headquarters in Washington. "So it helps to have a ready-made library of names in advance to officially submit to the IAU.”

The International Astronomical Union (IAU) in Paris is the formal authority for naming celestial bodies. Submissions must follow a set of accepted themes and guidelines set out by the IAU’s Working Group for Planetary System Nomenclature.

According to the IAU, Pluto is a "dwarf planet"—that is, a planetary-mass object orbiting the Sun that is massive enough to be rounded by its own gravity but is not a planet or satellite. Unlike planets, these bodies have not cleared the neighborhood around their orbits, and their paths sometimes cross with other, often similar, objects. There are currently five identified dwarf planets in our Solar System, each named after a God from Greek, Polynesian, or Roman mythologies. These five bodies are Ceres, Pluto, Haumea, Makemake, and Eris.

The names of features on the bodies in the Pluto system are related to mythology and the literature and history of exploration.  Listed below are IAU-approved naming themes for Pluto and its largest moon Charon:

• Pluto: Names for the Underworld from the world's mythologies; gods, goddesses, and dwarfs associated with the Underworld; Heroes and other explorers of the Underworld; writers associated with Pluto and the Kuiper Belt; and scientists and engineers associated with Pluto and the Kuiper Belt.
•  Charon: Destinations and milestones of fictional space and other exploration; fictional and mythological vessels of space and other exploration; fictional and mythological voyagers, travelers and explorers.

A complete explanation of naming conventions may be found on the IAU website.

After the naming campaign concludes, NASA’s New Horizons team will sort through the names and submit its recommendations to the IAU. The IAU will decide whether and how the names will be used.

Ready to pick names?  Members of the public from around the world, of all ages and walks of life, are allowed to participate. Learn more at http://www.nasa.gov/newhorizons.

Smaller and cheaper particle accelerators?

Smaller and cheaper particle accelerators?

04/21/2015 02:28 AM EDT Traditionally, particle accelerators have relied on electric fields generated by radio waves to drive electrons and other particles close to the speed of light. But in radio-frequency machines there is an upper limit on the electric field before the walls of the accelerator "break down," causing it to not perform properly, and leading to equipment damage. In recent years, however, scientists experimenting with so-called "plasma wakefields" have found that accelerating electrons on ...
