" ... For the very first black hole-black hole merger seen by LIGO, the signal that arrived at NASA's Fermi telescope was weak and arrived without directional information. It was only a 2.9-sigma signal: potentially a false positive detection; the 0.22% odds of a "false alarm" are very high by physics standards. The gamma-ray burst candidate occurred when the detector was poorly-oriented with respect to the event, and ESA's complementary INTEGRAL satellite saw no signs of any high-energy emission. ... "
" ... The mighty space telescope in orbit of Earth—up there for 30 years now—captured the mergers while astronomers were studying how quickly stars are forming in distant galaxies. ... "
" ... The viewing area of Hubble (top left) as compared to the area that the Nancy Roman telescope ... [+] (formerly WFIRST) will be able to view, at the same depth, in the same amount of time. Its wide-field view will allow us to capture a greater number of distant supernovae than ever before, and will enable us to perform deep, wide surveys of galaxies on cosmic scales never probed before. If dark energy varies by more than 1% from a cosmological constant, we'll know in under a decade. ... "
" ... Through a telescope, its features are spectacular. ... "
" ... Without the ability to survey the entire sky, however, we’re extremely likely to break the current record, but not to set the ultimate, all-time, never-to-be-broken record for most distant galaxy. Even with the advanced capabilities of our next-generation space telescope, NASA’s James Webb will be able to look back to about 200-250 million years after the Big Bang: an improvement that basically halves the time since the Big Bang that Hubble can observe. ...
