The solar system is stable for at least the next 100,000 years

It's nice to have a feel-good story every now and then, so here's one to keep the existential dread at bay: the Earth won't be flung off into deep space for at least 100,000 years. In fact, all of the planets in the solar...

Hubble captures swirling galactic trio

The mass of dust and bright swirls of stars in this image are the distant galaxy merger IC 2431. It lies 681 million light-years from Earth in the constellation Cancer. The NASA/ESA Hubble Space Telescope has captured a triple galaxy merger in progress. It also captured a...

Scientists discover how galaxies can exist without dark matter

Astrophysicists from the University of California reported that when tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter. These matters we can't see directly. But these matters do exist. Because without its gravitational effects they...

The magnetic field in the Milky Way filamentary bone G47

Star formation in the Milky Way occurs in long, dense filaments of gas and dust. It stretches along the spiral arms. Dubbed "bones" delineate the galaxy's densest skeletal spiral structures. These filaments are fifty times longer. They are wide and have coherent internal motions...

Dying stars can still give birth to planets

KU Leuven astronomers have discovered that some types of stars can possibly still form planets. Because of this, theories on planet formation will need to be adjusted. Earth was formed not long after the sun. Sun started to burn 4.6 billion years ago and the...
