WISE thermal-infrared images of (29075) 1950 DA. The image scale is 2.75 arcsec per pixel for the W1, W2 and W3 bands and 5.53 arcsec per pixel for the W4 band. White pixels are ‘bad’ pixels that do not contain data. The object seen in the red circle is (29075) 1950 DA. (Credit: Rozitis, MacLennan, Emery)

From objects as small as Newton’s apple to those as large as a galaxy, no physical body is free from the stern bonds of gravity, as evidenced in this stunning picture captured by the Wide Field Camera 3 and Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope.

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)

Could a mystery signal that has been detected be proof of dark matter? While searching through the fundamental structures of various galaxy clusters, astrophysicists located at Harvard University found a bizarre discharge line they are having trouble in identifying. (Credit: Kimberly Ruble)
