Summary:
The Chandra image of N49B, the remains of an exploded star, shows a cloud of multimillion-degree gas that has been expanding for about 10,000 years. A specially processed version of this image reveals unexpectedly large concentrations of the element magnesium.

The Chandra image of N49B, the remains of an exploded star, shows a cloud of multimillion-degree gas that has been expanding for about 10,000 years. A specially processed version of this image reveals unexpectedly large concentrations of the element magnesium.

Magnesium, created deep inside the star and ejected in the supernova explosion, is usually associated with correspondingly high concentrations of oxygen. However, the Chandra data indicate that the amount of oxygen in N49B is not exceptional. This poses a puzzle as to how the excess magnesium was created, or, alternatively, how the excess oxygen has escaped detection.

The amount of magnesium in N49B is estimated to be about equal to the total mass of the Sun. Since the Sun contains only about 0.1 percent of magnesium by mass, the total mass of magnesium N49B is about a thousand times that in the Sun and its planets.

Magnesium, the eighth most abundant material in the Earth's crust, is a mineral needed by every cell of our bodies. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, and bones strong. It is also involved in energy metabolism and protein synthesis. Fortunately for us, and thanks to stars such as the one that produced N49B, there is an abundant supply of magnesium in the Universe.

Nasa Gives You An Excuse to Post a Selfie on Earth Day

TheStreet (Apr. 22, 2014) NASA is inviting all social media users to take a selfie of themselves alongside nature and to post it to Twitter, Facebook, Flickr, Instagram, or Google Plus with the hashtag #globalselfie. NASA's goal is to crowd-source a collection of snapshots of the earth, ground-up, that will be used to create one "unique mosaic of the Blue Marble." This image will be available to all in May. Since this is probably one of the few times posting a selfie to Twitter won't be embarrassing, we suggest you give it a go for a good cause. Video provided by TheStreet
