It's the most in-depth study of planet-killing stars ever conducted.
A Hubble Space Telescope image of the star cluster NGC 3293 overlain by Chandra X-ray Observatory data in magenta spots marking bright X-ray sources.
Stars like the sun are highly energetic bodies capable of blasting away the atmospheres of planets in their orbits before life could have a chance to take hold, and a new study of a cluster of especially young stars has given us an even better understanding of how this process occurs.
To investigate this idea, researchers used the telescope to look at nearly a dozen"open clusters" containing a total of more than 6,000 youngthat formed around the same time, with ages ranging from 7 million to 25 million years old, and compared the data to earlier Chandra studies of stars as young as 500,000 years old. These stars are a particularly strong source of X-rays that are produced by intense magnetic fields generated by the nascent stars' internal dynamos.
