Here’s an awesome photo to start your day: The International Space Station currently has five spacecraft docked to it — the most that can be currently attached. If any of the world’s space agencies, or private companies like SpaceX were to send up another spacecraft today, they’d need to circle until another parking space becomes available. (Credit: NASA)

“This piece of information, that has always been a dream, and never was thought of as being within human grasp. But here in the year 2014 on finds that perhaps this mission is going to be telling us how the universe started,” said Harwit, who is an expert in infrared astronomy and works as a member of the ESA’s Submillimeter Wave Astronomical Satellite, as well as on the Herschel Telescope.

Plot of CPU transistor counts against dates of introduction. Note the logarithmic vertical scale; the line corresponds to exponential growth with transistor count doubling every two years. The curve shows Moore’s law – the doubling of transistor counts every two years. The y-axis is logarithmic, so the line corresponds to exponential growth. (Credit: Wgsimon)

These images show a diamond sample with a hemispherical lens (right and lower left), and the location of a single electron spin/quantum state visible through its light emission (upper left). The scale bar on the image at upper left measures five microns, the approximate diameter of a red blood cell. (Credit: Courtesy of Awschalom Lab/University of Chicago)

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)

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)

Every once in a while I think that there maybe is no fundamentally smallest unit of length; that all these arguments for its existence are wrong. I like to think that we can look infinitely close into structures and will never find a final theory, turtles upon turtles, or that structures are ultimately self-similar and repeat.(Credit: Sabine Hossenfelder, Sanghyuk Moon)

NIST researcher Kevin Dwyer with the silicon enrichment apparatus. The process begins at the left, where natural-abundance silicon in the form of silane gas (SiH4) is ionized. The ions pass through a magnetic field (top left), which causes their paths to curve to different degrees based on their mass. The silicon-28 ions, now separated from the other silicon isotopes, are decelerated through an ultra-high vacuum chamber (top center) and into the deposition chamber (top right) (Credit: Pomeroy, NIST, Dwyer)

A protein folding funnel, the product of algorithms created by Rice’s Center for Theoretical Biological Physics, is a graphic representation of the energy landscape a protein navigates as it goes from its initial floppy state to a folded, functional unit. The funnel shows smooth slopes as well as outcroppings where parts of a protein may pause while others catch up, and also traps that could cause a protein to misfold. New Rice research shows how the interplay between evolution and physics developed the skills necessary to conserve useful proteins. (Credit: Center for Theoretical Biological Physics/Rice University)
