If recent news that researchers observed the largest gamma ray burst ever has you nervous about getting blasted into extinction, the researchers themselves say chances of that are exceedingly rare.

NASA's Juno Spacecraft Hears Amateur Radio Operators Say 'Hi': Message was first-of-its-kind for an interplanetary spacecraft

Posted: 10 Dec 2013 12:25 PM PST

In a first-of-its-kind activity for an interplanetary spacecraft, thousands of amateur (ham) radio operators around the world were able to say "Hi" to NASA's Juno spacecraft Oct. 9 as it swung past Earth on its way to Jupiter.

Astronomers solve temperature mystery of planetary atmospheres

An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, astronomers have found, and knowing that may help in the search for potentially habitable worlds.

Recipe for a Universe: Apply heat and stir

Apply heat and stir; an expanding universe can emerge in a remarkably simple way, say scientists. When soup is heated, it starts to boil. When time and space are heated, an expanding universe can emerge, without requiring anything like a "Big Bang." This phase transition between a boring empty space and an expanding universe containing mass has now been mathematically described by researchers. The idea behind this result is a remarkable connection between quantum field theory and Einstein's theory of relativity.

Ultrasound microscopy: Aid for surgeons to make the invisible, visible

Instead of waiting an hour or more, tissue can be tested almost immediately with a new ultrasound microscope, and because the reflected sound varies depending on the type of cancer, a doctor can interpret the type of disease from the image by comparing it to a reference material.
