How do Earth, the planets, and the heliosphere respond? © 2019 Macmillan Publishers Limited, part of Springer Nature. [, One of the super-spherical gyroscopes of Gravity Probe B. Theory predicts that at high energies, the ratio of positrons to electrons ought to be lower than it is at lower energies. By noting this change in direction relative to the star, the twists of space-time could be measured. An arcsecond is 1/3600th of a degree. The project also touched the lives of hundreds of young scientists: "Because it was based at a university many students were able to work on the project," says Everitt. Aguilar, M. et al. The WMAP mission succeeded the COBE space mission and was the second medium-class (MIDEX) spacecraft in the NASA Explorers program. The new Planck maps also remove an apparent mismatch between Planck and WMAP data concerning such cosmic parameters as the density and distribution of matter, Bouchet notes. The all-sky map shows the direction of the polarization as black lines, while the colour scale indicates the polarization intensity, increasing from white to black. The positron signal could still be due to dark matter, but only if the probability of dark-matter collisions was substantially lower in the early Universe than it is today. WMAP has been stunningly successful, producing our new Standard Model of Cosmology. Stuff in Space is a realtime 3D map of objects in Earth orbit, visualized using WebGL. The first results were issued in February 2003, with major updates in 2005, 2007, 2009, 2011, and now this final release.

Although they appear to rule out one class of dark-matter models, the latest Planck data confirm that 26% of the total massâenergy budget of the Universe is made up of dark matter. The purpose of the Explorers Program is to allow for frequent, high quality space science investigations.
