Working with NASA on its Wide - Field Infrared Survey Telescope (WFIRST) mission, due to launch sometime after 2020 (see «Mapping the Dark,» page 47), Perlmutter will help choose between the different models by studying groups of supernovae that lie farther out in space than any yet studied, following the universe's expansion history back in time.

But Michilli points out that in order to drive such strong magnetic fields, the supernova remnant would have to be a million times brighter than even the brightest remnant in the Milky Way, the Crab nebula (SN: 1/1/11, p. 11).

More common lower - energy cosmic rays — thought to emerge in the aftermath of supernova explosions in the Milky Way — curve so much in the galaxy's magnetic field that they appear to come from all over the sky.

The circular rings in the center - left of the image are supernova remnants caught in the strong magnetic field of the galaxy's core.

Janka «is doing the leading work» in this highly competitive field, says supernova pioneer Stanford Woosley of the University of California, Santa Cruz.

The stronger moving magnetic fields produced in supernova explosions could provide the energy for most other cosmic rays.

We find good agreement in the regions of ove... ▽ More We derive an accurate mass distribution of the galaxy cluster MACS J1206.2 - 0847 (z = 0.439) from a combined weak - lensing distortion, magnification, and strong - lensing analysis of wide - field Subaru BVRIz» imaging and our recent 16 - band Hubble Space Telescope observations taken as part of the Cluster Lensing And Supernova survey with Hubble (CLASH) program.

With the advent of new wide - field, high - cadence optical transient surveys, our understanding of the diversity of core - collapse supernovae has grown tremendously in the last decade.

This means they could predict when and where in the field the image of the supernova would appear next.

Photographed about eight days after it exploded, Supernova 1997ff (SN1997ff) was found by astronomers comparing the northern Hubble Deep Field, a 10 - day observation of a tiny region of sky first explored by the Hubble Space Telescope in 1995, with a follow - up observation in 1997.

[Obviously, if they were any further away, or if the random supernovas blew up too early to become part of the solar system's dust cloud, or were traveling too fast to be captured by what would become part of the solar system's dust cloud, or were thrown out too slow to get here in time, or were formed but were inside another star gravity field and never thrown back into space, even more dust would be lost in space, but let's keep the problem easy.

GCRs are modulated by both solar magnetic field, which is largely unpredictable in strength except for generalities associated with 11 - year sunspot cycle and is also modulated by unpredictable events like nearby supernovas, and by more predictable very very long slow changes in intensity due to the solar system traversing spiral arms of our galaxy and wandering above and below the galactic plane in cycles lasting tens and hundreds of millions of years.
