Test20
This is a test – please disregard.
This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth. NASA, ESA, CSA, and STScI

This one-room sci-fi thriller should take its MacGuffin more seriously
In Breathe, Earth is stripped of its oxygen, the plants are dead, oceans are dried up, no one trusts anyone — but we don't know what caused it. This sci-fi film fails to stand out among superior one-room thrillers, says Simon Ings
