Chandra X-ray Observatory Articles

The images of Trumpler 3 and NGC 2353 are open clusters that contains hundreds of young stars that are gravitationally bound together because they formed from the same gas cloud. In this composite image of the clusters, X-rays from Chandra (purple) have been combined with an optical image from the PanSTARRS telescope in Hawaii (red, green, and blue). The stars look like fuzzy dots of different sizes dotting the darkness of space.

A study using NASA’s Chandra X-ray Observatory found that young Sun-like stars in several clusters emit far less X-ray radiation than expected, a result that could improve prospects for life on nearby planets.

Key Takeaways

NASA says young Sun-like stars are dimmer in X-rays than previously thought.
The study examined eight clusters aged 45 million to 750 million years.
