A star in a galaxy passes by a black hole closely enough to be destroyed once every 10,000 years. It is possible to detect the death of a star in a fairly distant galaxyas the destruction of a star generates a bright X-ray flare; it is only necessary to distinguish such a flare from other types of X-ray radiation. Because flares occur in a variety of astrophysical processes, the task of finding stars destroyed by black holes is quite complicated. (Credit: Sergei Sazonov)

Some of the best evidence for parallel worlds actually arrives courtesy of an enigmatic oddity within deep-space, careening toward the Milky Way at an incredible 200,000 miles per hour. Though it’s more than 2 million light years away, the Andromeda galaxy, appears to engage in anomalous behavior which suggests a strange gravitational phenomenon. Specifically, gravity that could be draining from another universe, as yet invisible to us, could be the impetus behind such anomalous phenomena. (Credit: Micah Hanks)

Having a single point in contact with the ground lets a ballerina spin. In the same way, a quantum state is dynamic because it can turn about a point thanks to quantum uncertainty, say CQT and Oxford researchers. (Credit: Michael Garner, courtesy English National Ballet)

CDF physicist Petar Maksimovic, professor at Johns Hopkins University, presented the discovery to the particle physics community at Fermilab. He explained that the two types of Sigma-sub-b particles are produced in two different spin combinations, J=1/2 and J=3/2, representing a ground state and an excited state, as predicted by theory.

Scientists of the early 20th century argued that tidal forces had caused the sun to spit out the planets when a rogue star passed too close. It was a kind of drive-by shooting theory of planetary formation known as the “Planetesimal Hypothesis.” (Credit: NASA, M. Strauss)

An illustration of the extent to which the atoms, in a small cluster of atoms, vibrate. The spheres represent the range of motion of the atoms, rather than the atoms themselves – the spheres have been exaggerated in size by 45 times in order to ease visualisation. The atoms on the surface have larger ranges of motion than those in the middle of the cluster. (Credit: University of York)

To celebrate the NASA-ESA Hubble Space Telescopes 16 years of success, NASA and the European Space Agency are releasing this mosaic image of the starburst galaxy, Messier 82 (M82), made in March 2006. It is the sharpest wide-angle view ever obtained of M82, a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions. Located 12 million light-years away, it is also called the “Cigar Galaxy” because of the elongated elliptical shape produced by the tilt of its starry disk relative to our line of sight. (AP Photo/NASA-ESA)
This image of the galaxy Messier 82 is a composite of data from the Chandra X-Ray Observatory, the Hubble Space Telescope and the Spitzer Space Telescope. The intermediate-mass black hole M82 X-1 is the brightest object in the inset, at approximately 2 o’clock near the galaxy’s center. (Credit: NASA/H. Feng et al.)

Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris.

“The puzzle has been how these ‘seed’ black holes grew into the monsters that we now see within the time available, a few billion years at best,” says Priyamvada Natarajan, who proposes that early quasars took in a “super boost,” feasting from large reservoirs of gas that were part of early star clusters.

Experimental arrangement. A tip is approached to a distance of micrometres from a grounded highly ordered pyrolytic graphene (HOPG) surface carrying Ag nanostructures (illustrated in the inset). Electrons are field-emitted from the tip when a negative tip voltage Vt of hundreds of volts is applied, and the surface plasmon resonance (SPR) of the Ag nanostructures is excited by the field-emitted electrons under a strong electric field introduced by the tip–sample bias. The backscattered electrons are collected and analysed by the TEEA. (Credit: Nature Physics (2014) doi:10.1038/nphys3051)

Because of that alacrity, and the fact that they had repeat observations at roughly a decade’s detach, the Russian scientists were able to single out stars that dimmed by at least tenfold. They’ve been named 1RXS J114727.1 + 494302, 1RXS J130547.2 + 641252, and 1RXS J235424.5-102053. (Credit: Davies, NASA)
