Observations made by the Herschel space observatory have revealed 15 protostars in the constellation Orion, the biggest star formation area near our own solar system. The observatory was the first telescope to reveal the grouping, with previous studies of the area missing the stars which are thought to be some of the youngest and coldest in the constellation. The discovery is a significant step in furthering our understanding of how stars form.
