Springtime is blooming on Neptune! This might sound like an oxymoron because Neptune is the farthest and coldest of the major planets. But NASA Hubble Space Telescope observations are revealing an increase in Neptune's brightness in the southern hemisphere, which is considered a harbinger of seasonal change, say astronomers.

People worldwide may celebrate July 4, 2005, as the day their names reach a comet. NASA is launching a campaign to send hundreds of thousands of names to comet Tempel 1. The names will be carried on board NASA's Deep Impact spacecraft, the first deep-space mission designed to really reach out and touch a comet.

In one of the largest and most detailed celestial images ever, astronomers unveil the coil-shaped Helix Nebula giving us a breathtaking look down a tunnel of glowing gases that is a million million kilometres long. The fluorescing tube is pointed nearly directly at Earth, so it looks more like a bubble than a cylinder.
