A stellar outburst – pre-supernova burst – surprises

On Oct. 11, 2006, astronomers witnessed a stellar outburst. It was labeled Supernova (SN) 2006jc. This same star had undergone a mysterious outburst two years earlier.

Economist Scott Barrett values nature

It seems obvious there's economic value in nature's raw potential for goods. But nature has other, perhaps less obvious, economic value, said economist Scott Barrett.

Developing world values nature differently

Partha Dasgupta told Earth & Sky that, in the developing world, natural resources aren't just amenities. Instead, they're economic necessities.

1st look inside quasars with Xinyu Dai

The astronomers who accomplished this research likened the effect to being able to look at the quasars under a microscope.

Eclipsing brown dwarfs with Kelvan Stassun

Astronomers studied a pair of brown dwarfs in the direction of the Orion Nebula to learn fundamental properties of eclipsing brown dwarfs.

First galaxies seen by cosmic telescope

Located two billion light-years away, Abell 2218 is an example of a huge galaxy cluster that can bend light, thereby acting as a 'telescope' for astronomers. It works because the gravity of a large mass in space - like a galaxy cluster - bends and focuses the light from galaxies that lie behind it.

High-velocity stars in the galactic halo

There are billions of stars in our Milky Way galaxy - the stars we see at night when we look in a clear dark sky. To our eyes, these stars look as if they're standing still. But they're really moving. One of the nearest 45 stars, called Kapteyn's star, is an example of a high-velocity stars moving in the space near our sun.

Astronomers discover a tiny possible solar system

Ancient climate change made plants shift range

Ancient climate change made plants shift range. Read more about the research with Jonathan Bloch of the University of Florida Museum of Natural History.

Dusty disks might contain planet-forming clues

Dusty disks around young stars in infrared images provide a way to directly study these star-forming disks. Read more about how astronomers are studying them.
