A group of astronomers studying more than 221,000 galaxies has measured the energy generated within a large portion of space more precisely than ever before, discovering that it’s only half what it was two billion years ago and fading.

Using the Cosmic Web Imager (CWI) to study a system with two quasars 10 billion light-years away, the astronomers have unveiled a protogalaxy being fed cool gas by a filament of the cosmic web. The quasar UM 287 is the larger object at right; the newly-discovered protogalaxy is above and to the left of UM 287. This picture combines a visible light image of the system with CWI data; a filament of the cosmic web can be seen funneling cold gas onto the protogalaxy.

An artist’s impression of the binary system PSR J1023+0038: the extremely dense, rapidly-spinning neutron star, just 10-15 km in size, is in a close orbit with a more normal companion star. The strong gravity of the neutron star pulls gas from its companion, which spirals in towards the neutron star, forming a disk. Some fraction of that gas gets accelerated outwards in energetic, oppositely-directed jets, which give off the radio waves that can be seen by Earth’s radio telescopes. Image credit: ICRAR.

This image shows how stellar orbits in the Milky Way Galaxy can change. It shows two pairs of stars, marked as red and blue, in which each pair started in the same orbit, and then one star in the pair changed orbits. The star marked as red has completed its move into a new orbit, while the star marked in blue is still moving. Image credit: Dana Berry / SkyWorks Digital, Inc. / SDSS collaboration.

This collage of radar images of 1999 JD6 was collected by NASA scientists on July 25, 2015. The asteroid appears to be a contact binary. These views, which are radar echoes, were obtained by pairing NASA's 230-foot-wide Deep Space Network antenna at Goldstone, California, with the 330-foot Green Bank Telescope in West Virginia. Using this approach, the Goldstone antenna beams a radar signal at an asteroid and Green Bank receives the reflections. The technique, referred to as a bistatic observation, dramatically improves the amount of detail that can be seen in radar images. Image credit: NASA / JPL-Caltech / GSSR.

This graphic illustrates how a star can magnify and brighten the light of a background star when it passes in front of the distant star. If the foreground star has planets, then the planets may also magnify the light of the background star, but for a much shorter period of time than their host star. Astronomers use this method, called gravitational microlensing, to identify planets. Image credit: NASA / ESA / A. Field, STScI.
