MILKY WAY SHROUDED IN HY­DRO­GEN

Sky at Night Magazine - - BULLETIN -

The first de­tec­tion of the halo of hy­dro­gen around our Galaxy has been made. Sim­i­lar clouds have been seen around other gal­ax­ies, but as­tronomers have strug­gled to de­tect our own halo, as it is so dif­fuse when viewed from the in­side. In­stead, re­searchers used spec­tral data from 732,225 gal­ax­ies taken as part of the Sloan Dig­i­tal Sky Sur­vey. Em­bed­ded in these spec­tra were sig­nals in­di­cat­ing a shroud of hy­dro­gen sur­round­ing our Galaxy.
