  • One of today’s most fashionable astronomy pursuits is the hunt for planets beyond our solar system. And one was found orbiting Proxima Centauri, which happens to be the very nearest star to Earth. On this week’s “Strange Universe,” we talk about aliens and exoplanets.
  • If you’re hearing this Sunday, well, at 11:33 this morning Eastern Daylight Time, it’s the vernal equinox, when we read that "Day and night are equal." But some people must surely glance at their local sunrise and sunset listings and see that day is longer than night at the equinox. Real equality happened several days ago. The culprit is our atmosphere, which bends the sun’s image upward. But, hey, it’s close enough. Like the date itself. If "March 21" pops to mind, you're probably over 50. The final March 21 equinox happened 32 years ago.
  • Mars will come closer and closer as the year goes on. Venus’ extreme brilliance will be seen over most of the year, but it’s only now and the next two weeks that it hovers just above Mars. This week we’ll hear about our two nearest planetary neighbors, Mars and Venus, and why now is only time we’ll see them together.
