Map of the Universe from Johns Hopkins University and others.....

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.

First Exomoon Found! A Neptune-Sized Moon Orbiting a Jupiter-Sized Planet

A pair of astronomers combing through data from the Kepler spacecraft have discovered the first exomoon. The moon is in the Kepler 1625 system about 8,000 light years away, in the constellation Cygnus. It orbits the gas giant Kepler 1625b, and, unlike all the moons in our Solar System, this one is a “gas moon.”

With Thanks to the Space Telescope Sience Institute



This diagram shows the sequence of photometric observations taken by Hubble. The purple object represents the planet Kepler 1625b, and the smaller green object is that planet’s exomoon. The exomoon travels in front of the star about 3.5 hours after the planet. Image: NASA, ESA, D. Kipping (Columbia University), and A. Feild (STScI)
