Gigantic Hole in Our Sun
A coronal hole was discovered by NASA in the bottom of the Sun that is fifty times larger than Earth. A coronal hole is an area in the Sun, where its magnetic field becomes open ended and high speed wind streams into the space. When pictured, the area appears darker because the lesser about of material in that particular spot. Because of Coronal holes, it is stated that the aurora borealis becomes brighter and more magnificent than ever. When NASA discovered the hole, it was unusual because the Sun was at its maximum cycle, where holes are usually discovered during their declining phase. The people who made this discovery probably majored in astronomy.

“Dark Matter and Dark Energy”
Recent discoveries that were made by scientists in Rome have found that dark matter is slowly depleting, being swallowed up by dark energy. Dark matter is the cosmic scaffolding on which our Universe is built. The scientists say that as dark energy grows, it interacts with dark matter, which cause it to slow the growth of structure in the cosmos. If the dark energy continues growing, while dark matter disappears, we will be left with a Universe that contains nothing. Dark matter provides a blueprint for structures to grow in our Universe. Since dark matter is evaporating, the structures have a slowed growth. The scientists in Rome surveyed different data, the growth of structures, to reveal different model tests of dark energy. I believe that the scientists, who discovered this, majored in cosmology.
