We're counting down to the April 8, 2024, total solar eclipse, which will cross North America. Colors look eerie just before the moon covers the sun. Why?
Constellations and asterisms are patterns of stars. Some asterisms consist of stars from different constellations, and some are part of one constellation.
Mars is ascending higher in the morning sky, and Venus is sinking sunward. Mars will be visible - but dim - before dawn for most of 2024. Then, by the year's end, it'll suddenly become noticeable!
Sirius is the brightest star in Earth's sky because of how close it is to us. It's so bright you might see glints of different colors flashing from it.
