Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.
Because of its proximity to Earth, and its similarity in size, mass and composition, Venus was once believed to hold life.
In fact, the idea of Venus being a tropical world persisted well into the 20th century, until the Venera and Mariner programs
demonstrated the absolute hellish conditions that actually exist on the surface.

Published on Aug 21, 2014 The Voyager 2 spacecraft flew by Triton, a moon of Neptune, on August 25, 1989. Paul Schenk,
a scientist at the Lunar and Planetary Institute in Houston, used Voyager data to construct this video recreating that exciting encounter.
This video zooms in on planetary nebula Messier 57, known as the Ring Nebula. The sequence begins with a view of the night sky near the constellation of Lyra. It then zooms through observations from the Digitized Sky Survey 2, and ends with a view of the nebula obtained by Hubble. The data of the region surrounding the Ring Nebula's central region are provided by the Large Binocular Telescope Observatory.

This video takes the viewer on a journey through space to the Sombrero Galaxy, also known as Messier 104 (M104). The NASA/ESA/CSA James Webb Space Telescope recently imaged the Sombrero galaxy with its MIRI (Mid-InfraRed Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring. The mid-infrared light highlights the gas and dust that are a feature of the star formation taking place among the Sombrero galaxy’s outer disc. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. It’s not a particular hotbed of star formation. The Sombrero galaxy is around 30 million light-years from Earth in the constellation Virgo.

The Crab Nebula is an expanding remnant of a star's supernova explosion. Located 6,500 light-years away, this glowing relic has been expanding since the star exploded, and it is now approximately 11 light-years in width. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula's eerie interior bluish glow. The blue light comes from electrons whirling at nearly the speed of light around magnetic field lines from the neutron star, which is the crushed ultra-dense core of the exploded star.
