Here's news about the most famous stellar nursery of all, the Orion Nebula. Previously, the distance to the Orion Nebula was estimated at about 1,500 or 1,600 light-years. But the Orion Nebula is actually closer than that by about 200 light-years, according to Rob Jeffries at Keele University in England.

... but that liquid isn't water. The lakes can't hold water because Titan is so far from the sun that any water on its surface would be solid ice. Instead of having liquid water, Titan's lakes are thought to be filled with methane in a liquid form.

Wolf 359 is one of the closest stars to Earth at only 7.8 light-years away. It is a red dwarf star, known to be a single star. Former studies of bright, easy-to-see stars indicated that most of them lie in multiple systems of two or three stars. But those earlier studies neglected small, faint stars like Wolf 359.

Ethno-botanist Darron Collins talks about rainforest logging. It may be more sustainable, but it'll take much more to save the rainforests. Read more.

Most stars reside in a galaxy. In 2006, astronomers used the Hubble Space Telescope to study over 5,000 stars found in the space between galaxies in the Virgo cluster. The lack of iron in these stars indicated that they may have come from small galaxies that got ripped apart when they passed too close to larger galaxies.

Older dwarf stars, such as Proxima Centauri, have fewer flares and starspots (the stellar equivalent of sunspots). Read more about older dwarf stars here.

Double centaurs are a centaur plus a compaion. Centaurs are icy planetoids orbiting the sun between the outer planets Jupiter and Neptune. Read more.

Scientists are now speaking of what they call the "coupled human-environment system." It's a new way of thinking about the relationship between nature and human beings.

Kai Lee said, "I think one of the great dilemmas we face is acknowledging this interdependence in a way which also enables us to live our lives. We don't want to be encumbered all the time with thinking about all the indirect consequences of what we're doing in the world. And I think that's a dilemma that we don't even recognize is a dilemma yet ... "
