European astronomers on Tuesday said they had found a distant star orbited by at least five planets in the biggest discovery of so-called exoplanets since the first was logged 15 years ago. One of the planets is nearly the mass of Earth.
The rotating corpses of massive stars can help scientists weigh the planets in the solar system. By carefully timing radio blips from spinning stellar leftovers called pulsars, astronomers have measured the masses of all the planets from Mercury to Saturn, plus all their moons and rings.
What's the matter with this cluster of galaxies? To find out what forms matter takes in the Abell 1689 cluster requires not only deep images from telescopes like the Hubble Space Telescope, but detailed computer modeling as well.

The powerful radio source in the center of M87 is a supermassive black hole, ripping away at the heart of the galaxy.
New research suggests moons orbiting Jupiter-class worlds are unlikely to exist - at least around the vast majority of extrasolar planets discovered so far.
Storms on the distant horizon and comet dust raining through the heavens above are combined in this alluring nightscape. The scene was recorded in the early hours of August 13 from the Keota Star Party site on the Pawnee National Grasslands of northeastern Colorado, USA.
Space is one damn interesting place, chock-full of wacky phenomena, and you don’t even need to work for NASA to understand it. Here’s a collection of interesting and altogether weird space facts that you probably didn’t learn in school or even on TV.
Thrust from a Titan 3/Centaur rocket launched NASA's Viking 1 spacecraft on a 505-million-mile journey to Mars on Aug. 20, 1975. Viking 2 followed three weeks later.
As we approach the 164th anniversary of Neptune's discovery, there's another reason why we should celebrate this astronomical event: the gas giant is about to
