Amazon Milk Frogs, also known as Mission Golden-eyed Tree Frogs or Blue Milk Frogs, were first found in Rio de Janeiro's Maracanã River. The name "Milk Frog" refers to the poisonous, white, milky secretion that this frog secretes when threatened. But what about that blue mouth? This species is most active at night and is known for its loud vocalizations.
Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.
The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy.
