HabEx, a space telescope with ultraviolet (UV), optical, and near-infrared (near-IR) imaging and spectroscopic capabilities, will have three primary science goals: (I) seek out nearby worlds and explore their habitability; (ii) map out nearby planetary systems and understand the diversity of the worlds they contain; (iii) enable new explorations of astrophysical systems from our own Solar System to galaxies and the Universe by extending our reach in the UV through near-IR.

This Hubble image shows ESO 021-G004, a spiral galaxy located approximately 130 million light-years away in the constellation Chamaeleon. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

NASA’s MAVEN Orbiter Maps Martian Upper Atmospheric Winds

Dec 13, 2019 by News Staff

On Earth, the Northern and Southern lights occur when the solar wind (electrically charged particles from the Sun) follow our planet’s geomagnetic field lines to the poles and collide with the upper atmosphere. Mars lacks a global magnetic field, so instead the solar wind piles up in front of Mars in a bow shock, which blocks charged particles from reaching the bulk of the atmosphere. However, in a process first observed by NASA’s MAVEN spacecraft, some solar wind protons can slip past the bow shock by first bonding with electrons from the Martian upper atmosphere to form hydrogen atoms. Because these hydrogen atoms are electrically neutral, they can pass through the bow shock and go on to create an ultraviolet proton aurora on the dayside of Mars.
