“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…

“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’ve come incredibly far in our quest to learn how the Universe came to be the way it is today. We can see out in space for tens of billions…

“One way or another the first stars must have influenced our own history, beginning with stirring up everything and producing the other chemical elements besides hydrogen and helium. So if we really want to know where our atoms came from, and how the little planet Earth came to be capable of supporting life, we need…

“We have chased away the clouds, the sky is all ‘rose.’” -Francois Hollande When you have a light curve with two different large, periodic dips in it, a binary star system is the likeliest explanation. The stars eclipse, and in the case where they’re so close their envelopes touch, they’re known as contact binaries. That,…

“The history of astronomy is a history of receding horizons.” -Edwin Hubble Over its more than 25 year lifetime, the Hubble Space Telescope has shown us what the Universe truly looks like. It’s done so in a myriad of ways, from planets to stars – dying and forming – to galaxies to gravity’s effects to…
