The two brightest planets in Earth's night sky are millions of miles apart. But due to an astronomical quirk, they appear to be engaging in a cosmic dance tonight. Now that's a moment of awe.
Mercury, Venus, Mars, Jupiter and Saturn will be sequentially aligned and visible at dawn throughout June. The last time this happened was in 2004.
The James Webb Space Telescope will let scientists study small, rocky planets around distant stars in more detail than ever before. After decades of work, it could head into orbit later this year.
Potentially, observers in plenty of star systems could have detected Earth sometime in the last 5,000 years. More stars will soon move into positions that would let them see our planet.
Scientists have found a gas associated with living organisms in a region of Venus' atmosphere. They can't figure out how it got there if it didn't come from life.
