“Even with all the collected data we cannot say with 100% certainty that the ASASSN-15lh event was a tidal disruption event. But it is by far the most likely explanation.” -Giorgos Leloudas Last year, a record-shattering event occurred: we saw the brightest supernova ever observed in the Universe. It outshone the previous record holder by…

“Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save…

“If you are fearful, a horse will back off. If you are calm and confident, it will come forward. For those who are often flattered or feared, the horse can be a welcome mirror of the best in human nature.” -Clare Balding One of the most iconic astronomy images is that of the Horsehead Nebula.…

“We conducted the first fully blind, three-dimensional search for cool gas in the early universe. Through this, we discovered a population of galaxies that is not clearly evident in any other deep surveys of the sky.” -Chris Carilli The Hubble Ultra Deep Field and its successor images represent humanity’s deepest views of the stars in…

“Truth is tough. It will not break, like a bubble, at a touch; nay, you may kick it about all day like a football, and it will be round and full at evening.” -Oliver Wendell Holmes When isolated stars like our Sun reach the end of their lives, they’re expected to blow off their outer layers…

“He ate and drank the precious Words, his Spirit grew robust; He knew no more that he was poor, nor that his frame was Dust.” -Emily Dickinson When we look at spiral galaxies, we think of grand arms, star-forming regions and dust lanes lining our perspective. But unlike face-on galaxies, where everything looks the same,…

“He who would search for pearls must dive below.” -John Dryden If you want to know what types of stars are found all throughout a galaxy, looking at our own simply won’t do: too much of it is obscured by the plane and our position within it. But there’s an even more impressive galaxy —…

“In other words, theory attempts to segregate the minimum number of possible worlds which must include the actual world we inhabit. Then the observer, with new factual information, attempts to reduce the list further. And so it goes, observation and theory advancing together toward the common goal of science, knowledge of the structure and observation…

“That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only by gravitational pull, and a whopping 70 percent of the universe is made up of “dark energy,” described as a cosmic antigravity, as yet totally unknowable. It’s basically all mystery out there – all of it, with…

“Every single time you make a merger, somebody is losing his identity. And saying something different is just rubbish.” -Carlos Ghosn A galaxy cluster is the largest individual bound structure in the Universe, containing anywhere from dozens to thousands of times the mass of our Milky Way. Yet as the cosmic web grows and evolves,…
