A young star is speeding away from the Milky Way so fast that astronomers have been puzzled by where it came from; based on its young age it has traveled too far to have come from our galaxy.
It’s large, it’s fast, and it’s heading toward the Milky Way. Less than 40 million years from now, a giant cloud of hydrogen gas, clocked at 250 kilometers per second, will smash into our home galaxy, likely setting off a huge burst of star formation.
Astronomers searching for habitable worlds might do best to look for rocky planets several times larger than Earth. That’s because, according to a new study, our planet is at the lower end of the size range needed for plate tectonics—which scientists believe are vital for stabilizing temperatures enough for life.
A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late yesterday when the cycle’s first sunspot appeared in the sun’s Northern Hemisphere, said NOAA.
Scientists have come up with the radical suggestion that the universe’s end may come not with a bang but a standstill - that time could be literally running out and could, one day, stop altogether
Scientists think they have discovered the energy source of auroras borealis, the spectacular color displays seen in the upper latitudes of the Northern Hemisphere.
A physicist from Austria claims that our planet experiences something which resembles breathing; gravity gets weaker and stronger; according to him it takes about 700.000 years for such a cycle to take place and we are close to the moment where it is very weak
For the first time, scientists have proof two supermassive black holes exist together in the same galaxy, thanks to data from NASA’s Chandra X-ray Observatory. These black holes are orbiting each other and will merge several hundred million years from now, to create an even larger black hole resulting in a catastrophic event that will unleash intense radiation and gravitational waves.

GalaxyZoo is a project which harnesses the power of the internet - and your brain - to classify a million galaxies. By taking part, you’ll not only be contributing to scientific research, but you’ll view parts of the Universe that literally no-one has ever seen before and get a sense of the glorious diversity of galaxies that pepper the sky.
Using a technique that measures how much gravity bends light, astronomers say they have spotted early stars in galaxies more than 13 billion light-years away.
