Kavli Institute for Cosmology, Cambridge 27 Apr 2017, 08:53 UTC A young star recently observed to be surrounded by spiralling gas and dust could be one of the first to show planet formation ‘in action’ via a mechanism once thought to be unlikely. Astrophysicists at the University of Cambridge have used theoretical models to determine the origins of the striking large-scale spiral features surrounding a nearby star.

Universe Today 27 Apr 2017, 15:33 UTC One down, twenty-one to go! The Cassini spacecraft survived the first dive through the narrow gap between Saturn and its rings, and is now back communicating with Earth. It was a long day for Cassini scientists and engineers at the Jet Propulsion Laboratory while the spacecraft was out of contact for 20 hours during this first dive, signaling the beginning of the end for Cassini.
Starts With a Bang! 27 Apr 2017, 14:01 UTC The LHCb collaboration is far less famous than CMS or ATLAS, but the bottom-quark-containing particles they produce holds new physics hints that the other detectors cannot probe. Image credit: CERN / LHCb collaboration.Wanting there to be something beyond the standard model may be influencing what we actually investigate.“In recent years several new particles have been discovered which are currently assumed to be “elementary,” that is, essentially structureless. The probability that all such particles should be really elementary becomes less and less as their number increases. It is by no means certain that nucleons, mesons, electrons, neutrinos are all elementary particles.” -Enrico FermiOver at the Large Hadron Collider at CERN, particles are accelerated to the greatest energies they’ve ever reached in history. In the CMS and ATLAS detectors, new fundamental particles are continuously being searched for, although only the Higgs boson has come through. But in a much lesser-known detector — LHCb — particles containing bottom quarks are produced in tremendous numbers. One class of these particles, quark-antiquark pairs where one is a bottom quark, have recently been observed to decay in a way that runs counter to the Standard Model’s predictions. Even though the evidence isn’t very good, it’s the ...

The TeCake 27 Apr 2017, 07:23 UTC Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists’ understanding of the types of planetary systems that exist beyond our own. “This ‘iceball’ planet is the lowest-mass planet ever found through microlensing,” said Yossi Shvartzvald, a NASA postdoctoral fellow based at NASA’s Jet Propulsion Laboratory, Pasadena, California, and lead author of a study published in the Astrophysical Journal Letters. Microlensing is a technique that facilitates the discovery of distant objects by using background stars as flashlights. When a star crosses precisely in front of a bright star in the background, the gravity of the foreground star focuses the light of the background star, making it appear brighter. A planet orbiting the foreground object may cause an additional blip in the star’s brightness. In this case, the blip only lasted a few hours. This technique has found the most distant known exoplanets from Earth, and can detect low-mass planets that are substantially farther from their stars than Earth ...
