Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
135-million-year-old marine crocodile sheds light on Cretaceous life

Research shows that glossy black-cockatoos prefer to feed from trees growing in acidic soils
Glossy black-cockatoos are seed-eating birds that feed almost exclusively on the cones of drooping sheoak trees. However, counter-intuitively, they select trees that grow on the poorest soils found on ancient sedimentary rocks......»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
