This month you can catch planet pairs, our moon near red stars and more! Catch bright Venus in the predawn sky by looking for fainter Mars below it on Oct. 1, really close on the 5th and above Venus after that. In the Oct. 8 – 11 predawn sky watch the moon glide near the Pleiades star cluster and pass near the red stars Aldebaran in the constellation Taurus and Betelgeuse in Orion. Watch for more about when and where to look up this month! Credit: NASA
Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
