    Tracking the Birth of a ‘Super-Earth’

    July 12, 2017, Categories  Astronomy/Space

    The protoplanetary disk around HL Tauri, a million-year-old sunlike star located approximately 450 light-years from Earth in the constellation of Taurus, dwarfs our solar system (right). Taken by the ALMA array, this image reveals a series of concentric and bright rings, separated by gaps — features astronomers have struggled to explain until now. (Credit: ALMA (ESO/NAOJ/NRAO))

    Studying fungi to keep space travelers safe on new worlds

    July 12, 2017, Categories  Astronomy/Space, Biology/Biotechnology

    Dominant fungal population and succession patterns observed in 30-day occupation period of the ILMAH system. The OTUs presented in the bar graph are the most abundant. T20 surface samples show different fungal profile when compared to other time points. T30 samples show increase in fungal diversity when compared to other time point

    Human presence in closed habitats that may one day be used to explore other planets is associated with changes in the composition of the fungal community – the mycobiome – that grows on surfaces inside the habitat, according to a study published in the open access journal Microbiome.

    Outline of the microsatellite SOCRATES and the NICT optical ground station located in Koganei city. a. Picture of the lasercom terminal SOTA. b. Polarization states that encode the bits of the transmitted information. c. Optical ground station. d. Configuration diagram of the quantum receiver.

    Big step toward building a truly-secure global communication network. The National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.) developed the world’s smallest and lightest quantum-communication transmitter (SOTA) onboard the microsatellite SOCRATES...

    Hubble’s Hidden Galaxy

    July 11, 2017, Categories  Astronomy/Space

    IC 342 is a challenging cosmic target. Although it is bright, the galaxy sits near the equator of the Milky Way's galactic disk, where the sky is thick with glowing cosmic gas, bright stars, and dark, obscuring dust. In order for astronomers to see the intricate spiral structure of IC 342, they must gaze through a large amount of material contained within our own galaxy -- no easy feat! As a result IC 342 is relatively difficult to spot and image, giving rise to its intriguing nickname: the 'Hidden Galaxy.' Credit: ESA/Hubble & NASA
