Watching starbirth isn’t easy: tens of millions of years are needed to form a star like our Sun. Much like archeologists who reconstruct ancient cities from shards of debris strewn over time, astronomers must reconstruct the birth process of stars indirectly, by observing stars in different stages of the process and inferring the changes that take place. Studies show that half of the common stars, including our Sun, formed in massive clusters, rich with young stars, from which they eventually escape. As part of his PhD thesis work, Thomas Allen, University of Toledo, has been observing such a region where stars are forming.

Named Cep OB3b, this cluster is located in the northern constellation of Cepheus, and is similar in some ways to the famous cluster found in the Orion Nebula. But unlike the Orion Nebula, there is relatively little dust and gas obscuring our view of Cep OB3b. Its massive, hot stars have blown out cavities in the gaseous cloud with their intense ultraviolet radiation which mercilessly destroys everything in its path. Cep OB3b may show us what the Orion Nebular Cluster will look like in the future.

Asteroid Explorer “Hayabusa2” Name And Message Campaign


The Japan Aerospace Exploration Agency (JAXA) is scheduled to launch the asteroid explorer “Hayabusa2”*1 on the H-IIA Launch Vehicle in 2014. The Hayabusa2 will arrive at an asteroid in 2018 to investigate it for one and half years, before returning to Earth in 2020.

JAXA will record and load your names, messages and illustrations on onboard devices (the target marker*2 and re-entry capsule*3) of the Hayabusa2. Through this campaign and Hayabusa2’s six-year space mission, we would like people to deepen their understanding of Japan’s space probe activities.
