Galactic turmoil ahead

The Milky Way and its closest neighbor, the Andromeda galaxy, are on course for “ a head-on collision,” says astronomer Roeland van der Marel of the Space Telescope Science Institute. But no need for precautions because the crash won’t happen for another 4 billion years. Researchers have long known that Andromeda, currently some 2.5 million light-years away, is moving toward […]

A Moon With Water

Astrobiologists searching the heavens for extraterrestrial life have a simple motto: “Follow the water, ”says The Washington Post. Water is an essential ingredient in all earthly biochemistry, so scientists believe it’s logical to look for life first on planets and moons with liquid water.New data from NASA’s Cassini spacecraft indicate that Enceladus, a tiny, ice-encrusted moon orbiting Saturn, may be […]

Our sun’s hotter sister

Stars are not born alone. Rather, they emerge from clouds of gas and dust in groups of up to 10,000, then slowly scatter through space. For the first time, astronomers have identified a star that came from the same solar nursery as our sun, some 4.5 billion years ago. This stellar relative—located 110 light-years away in the constellation Hercules—is hotter […]

Earth’s magnetic shield getting weaker

Earth’s magnetic field is weakening, and could all but disappear within the next 500 years—exposing our planet to intense solar radiation that would scour its surface of life, Reuters.com reports. Researchers say I the geological record indicates that Earth’s * magnetic field tends to switch polarity f every 250,000 years—and that it’s about 550,000 years overdue for a swap, which […]

The biggest thing in the universe

British astronomers have identified a celestial object so large that it challenges scientists’ basic assumptions about the nature of the universe. Huge-LQG is a cluster of 73 quasars, each of which lies at the center of its own galaxy.The structure measures 4 billion light-years across at its greatest dimension; our own Milky Way galaxy, which is 100,000 light-years across, is […]
