Could a ‘rogue star’ knock Earth out of orbit? Yes — and here’s why it could be a good thing.
About a billion years from now, the sun will have become much bigger, brighter and hotter, likely leaving Earth uninhabitable. However, a chance encounter with a passing star could save our planet by tossing it into a cooler orbit or helping it break free of the solar system entirely, a new theoretical study suggests. (Still,…

Scientists Discover a Stunning River of Stars Flowing Through Space
A stunning river of stars has been spotted flowing through the intergalactic space in a cluster of galaxies about 300 million light years away. Such bridges are known as stellar streams; and, at a length of 1.7 million light-years, the newly named Giant Coma Stream is the longest we’ve ever seen. And that’s not all:…

GUSTO
Astronomers who study the material between the stars are ready to “go for the gusto.” They’re planning to launch a telescope aboard a giant balloon. If everything goes as planned, it’ll loop around Antarctica for up to four months, staring deep into the Milky Way and a companion galaxy. The mission is known as GUSTO.…

Spider Pulsars are Tearing Apart Stars in the Omega Cluster
Pulsars are extreme objects. They’re what’s left over when a massive star collapses on itself and explodes as a supernova. This creates a neutron star. Neutron stars spin, and some of them emit radiation. When they emit radiation from their poles that we can see, we call them pulsars. In the last decade or so,…

Fermi has Found More than 300 Gamma-Ray Pulsars
In June 2008, the Gamma-ray Large Area Space Telescope began surveying the cosmos to study some of the most energetic phenomena in the Universe. Shortly after that, NASA renamed the observatory in the Fermi Gamma-ray Space Telescope in honor of Professor Enrico Fermi (1901-1954), a pioneer in high-energy physics. During its mission, Fermi has addressed questions regarding…

The planet LHS 3154 b seems way too big for its tiny star
The light of the M dwarf LHS 3154 scatters off the Neptune-sized planet LHS 3154 b in this artist’s concept. Credit: Penn State University In the annals of planet hunting, astronomers’ latest find is a bit of a head-scratcher: a giant exoplanet tightly orbiting a star so tiny, it’s hard to understand how the star…
