Black holes colliding, gravitational waves riding through space-time - and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers from the University of Zurich have now found that LISA could also shed light on the elusive dark matter particle.
Feature describes unexpected discovery of a role the process that seeds magnetic fields plays in mediating a phenomenon that occurs throughout the universe and can disrupt cell phone service and knock out power grids on Earth.
Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.
Most red dwarf stars have planet families but are prone to violent outbursts, making their planets less hospitable to life.
New research by a team led by an astrophysicist at the University of Warwick has a way of finally telling whether newly forming planets are migrating within the disc of dust and gas that typically surrounds stars or whether they are simply staying put in the same orbit around the star.
School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield, as part of a Queen Mary University of London research project.
Evgenij Zubko of Far Eastern Federal University (FEFU) in collaboration with other team members has developed a comprehensive model to explain the results of a photometric study of the Comet Schwassmann-Wachmann 1 (29P) which was successfully accomplished recently. The findings came as a real surprise revealed that the dust environment of 29P predominantly consists of only one type of material -- magnesium-rich silicate particles with presumably a small amount of iron (Fe-Mg silicates).
An international team of astronomers using the VIMOS instrument of ESO's Very Large Telescope have uncovered a colossal structure in the early universe. This galaxy proto-supercluster -- which they nickname Hyperion -- was unveiled by new measurements and a complex examination of archive data. This is the largest and most massive structure yet found at such a remote time and distance -- merely 2 billion years after the Big Bang.
A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, the findings would force significant revisions to several prominent theories posed as alternatives to the Standard Model of particle physics, which was developed in the early 1970s.
The universe's deep past is beyond the reach of even the mighty Hubble Space Telescope. But a new review published in Frontiers in Astronomy and Space Sciences explains how creation of the first stars and galaxies is nevertheless being mapped in detail, with the aid of computer simulations and theoretical models -- and how a new generation of supercomputers and software is being built that will fill in the gaps.
