Valuable insights as neutron star passed through stellar winds

SPACE 01.24.2019 16:27 PM

Data recorded by NASA's Chandra X-ray Observatory of a neutron star as it passed through a dense patch of stellar wind emanating from its massive companion star provide valuable insight about the structure and composition of stellar winds and about the environment of the neutron star itself.

New detector fails to confirm would-be evidence of dark matter

01.23.2019 16:07 PM

Almost 20 years ago, the DAMA/LIBRA experiment operated at Italy's Gran Sasso National Laboratory - LNGS began publishing data showing that it had detected a signal modulation produced by an interaction with the Milky Way's dark matter halo.

Scientists find increase in asteroid impacts on ancient Earth by studying the moon

01.19.2019 08:33 AM

TORONTO, ON (Canada) - An international team of scientists is challenging our understanding of a part of Earth's history by looking at the Moon, the most complete and accessible chronicle of the asteroid collisions that carved our solar system.

Saturn hasn't always had rings

01.18.2019 08:17 AM

In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists in Italy and the U.S. have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn's history.

From emergence to eruption: Comprehensive model captures life of a solar flare

01.16.2019 15:08 PM

A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.

Double star system flips planet-forming disk into pole position

01.14.2019 13:26 PM

New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars

Pair of colliding stars spill radioactive molecules into space

07.31.2018 15:49 PM

When two Sun-like stars collide, the result can be a spectacular explosion and the formation of an entirely new star. One such event was seen from Earth in 1670.

07.24.2018 15:16 PM

Researchers unravel more mysteries of metallic hydrogen Metallic hydrogen is one of the rarest materials on Earth, yet more than 80 percent of planets--including Jupiter, Saturn, and hundreds of extrasolar planets--are composed of this exotic form of matter.

NASA Finds The Age Of TRAPPIST-1 Is Twice Older Than Solar System

08.14.2017 19:32 PM

A recent research on TRAPPIST-1 suggests it is almost 9.8 billion years old, twice the age of the solar system. It is basically a dwarf star residing 40 light-years away from the solar system.

Mysterious Radio Signal From Outer Space Is Solved After 40 Years, It Is Not Alien

07.24.2017 14:45 PM

A mysterious radio signal received 40 years ago is now solved. The signal that came from Ross 128, 11 light-years away from Earth is not a message from aliens.
