ESO telescope reveals what could be the smallest dwarf planet yet in the solar system

Astronomers using ESO's SPHERE instrument at the Very Large Telescope (VLT) have revealed that the asteroid Hygiea could be classified as a dwarf planet. The object is the fourth largest in the asteroid belt after Ceres, Vesta and Pallas. For the first time, astronomers have observed Hygiea in sufficiently high resolution to study its surface and determine its shape and size. They found that Hygiea is spherical, potentially taking the crown from Ceres as the smallest dwarf planet in the solar system.

Dolphins demonstrate coordinated cooperation

Researchers investigated the cooperative abilities of dolphins. Utilizing a simplified Hirata Task, the team found that dolphins coordinated their behavior to work together on a shared task. Specifically, the 'initiator' would wait on their partner and the 'follower' would coordinate their swimming speed to match the initiator's behavior.

Putting the 'bang' in the Big Bang

Physicists have simulated in detail an intermediary phase of the early universe that may have bridged cosmic inflation with the Big Bang. This phase, known as 'reheating,' occurred at the end of cosmic inflation and involved processes that wrestled inflation's cold, uniform matter into the ultrahot, complex soup that was in place at the start of the Big Bang.
