Meteor Dust
What's happening to this meteor? It is shedding its outer layers as it passes through the Earth's atmosphere and heats up. The sudden high temperatures not only cause the bright…
M104: The Sombrero Galaxy in Infrared
This floating ring is the size of a galaxy. In fact, it is a galaxy -- or at least part of one: the photogenic Sombrero Galaxy , one of the largest galaxies in the nearby Virgo…
Jupiter with the Great Red Spot
Jupiter reaches its 2026 opposition today, January 10. That puts our Solar System's most massive planet opposite the Sun and near its closest and brightest for viewing from planet…
Ice Halos by Moonlight and Sunlight
