“No matter what technique you use, you should get the same value for the expansion rate of the universe today.” -Ben Hoscheit When you think of the Universe on the largest scales, you likely think of galaxies grouped and clustered together in huge, massive collections, separated by enormous cosmic voids. But there’s another kind of…

“N6946-BH1 is the only likely failed supernova that we found in the first seven years of our survey. During this period, six normal supernovae have occurred within the galaxies we’ve been monitoring, suggesting that 10 to 30 percent of massive stars die as failed supernovae.” -Scott Adams Everyone knows the recipe for a black hole:…

“We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe.” -Edwin Hubble When you look out at the distant Universe, you…

“We’ve taken a major step back in time, beyond what we’d ever expected to be able to do with Hubble. We see GN-z11 at a time when the universe was only three percent of its current age.” -Pascal Oesch Arriving at our eyes after a journey of 13.4 billion years, the light from galaxy GN-z11…

“Hey, if our eyes could access the infrared part of the light spectrum, the sky would be green and trees would be red. Some animals see in completely different ways, so who knows what colors look like to them. Nothing is really how we perceive it.” -Wendy Mass If you take a look at the…

“With the Hubble telescope and all the other things that are out there, I believe something would have come through. Today, I really believe we are unique.” -Mark Goddard Want to identify where stars are forming (or about to form) in the Universe? We’ve got no problem using visible light, which reveals unambiguous signatures associated…

“On a cosmic scale, our life is insignificant, yet this brief period when we appear in the world is the time in which all meaningful questions arise.” -Paul Ricoeur When it comes to the largest bound cosmic structures, it doesn’t get any bigger than galaxy clusters. Unless, that it, you consider when multiple galaxy clusters…

“For the first time we can learn about individual stars from near the beginning of time. There are surely many more out there.” -Neil Gehrels We know what NASA’s James Webb and WFIRST are designed for, and we know what we expect to find. James Webb will be the largest space telescope ever, focused mostly…

“The [James Webb] telescope is basically designed to answer the big questions in astronomy, the questions Hubble can’t answer.” -Amber Straughn Have you ever asked the biggest questions in the Universe? Questions like how the Universe came to be the way it is today? How the first stars and galaxies — the first light —…

“The problem is, you’re trying to find these really faint things, but you’re looking behind these really bright things. The brightest galaxies in the universe are in clusters, and those cluster galaxies are blocking the background galaxies we’re trying to observe.” -Rachael Livermore One of the biggest puzzles in science is exactly how the Universe…
