Coronol Holes Found In The Sun By Nasa

The dark area across the top of the sun in this image is a coronal hole, a region on the sun where the magnetic field is open to interplanetary space, sending coronal material speeding out in what is called a high-speed solar wind stream. The high-speed solar wind originating from this coronal hole, imaged here on Oct. 10, 2015, by NASA's Solar Dynamics Observatory, created a geomagnetic storm near Earth that resulted in several nights of auroras. This image was taken in wavelengths of 193 Angstroms, which is invisible to our eyes and is typically colorized in bronze.

Pink Meteorite reveals rare unstable element

Close-up of a meteorite sample, showing a ceramic-like refractory inclusion (in pink). Refractory inclusions are the oldest-known rocks in the solar system (4.5 billion years old). An analysis of uranium isotope ratios showed that a long-lived curium isotope was present early in the solar system when this inclusion was formed. Look below to see the entire meteorite. Image via Origins Lab, University of Chicago. A pink meteorite inclusion nicknamed Curious Marie shows that a highly unstable element, curium, was present in the early solar system. Researchers have found evidence that curium – a rare unstable heavy element – was present during the early formation of our solar system. Even though curium has long-since decayed into a form of uranium, signs of its presence remain in a pinkish ceramic inclusion nicknamed Curious Marie, a tribute to Marie Curie for whom the element curium was named. This discovery will help scientists refine their models of how elements are forged ...

Fluor-liddicoatite [or just Liddocoatite] is Rare.

Fluor-liddicoatite [or just Liddocoatite] is a rare member of the tourmaline group of minerals, elbaite subgroup, and the theoretical calcium end-member of the elbaite-fluor-liddicoatite series.
