The data in this image used a narrow-band filter that allowed H-alpha emission through to the telescope’s detectors. The particular filter, called F657N (F for filter, N for narrow, and 657 for the wavelength in nanometers) or the H-alpha filter, lets through light very close to the 656.46 nanometer H-alpha line’s wavelength. It reveals pinkish star-forming regions...
As chair of the Wisconsin State Assembly’s Committee on Campaigns and Elections, Republican State Assemblywoman Janet Brantjen has held hearings and collected documentary evidence about the corruption by some of the state’s Democrat mayors and election officials who used private money — “Zuck Bucks” — to turn election offices into campaign machines for Democrats...
The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across. Many stars are concentrated in its...
