Learning all about the Eagle, all over again

“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 While large parts of the internet are blacked out…

Did this Supernova Leave Nothing Behind?

“Nothing leads the scientist so astray as a premature truth.” -Jean Rostand One of the most awesome events, literally, that happens in this Universe is when stars — giant nuclear furnaces like our Sun — die in the most energetic way possible: a supernova.

Hubble: Still Unbeatable

“At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.” -Edwin Hubble Given the relative peace of our night skies, combined with the vast distances from…

A Holiday Hubble Handout: A Horseshoe?

“A farmer travelling with his load Picked up a horseshoe on the road, And nailed if fast to his barn door, That luck might down upon him pour; That every blessing known in life Might crown his homestead and his wife, And never any kind of harm Descend upon his growing farm.” -James Thomas Fields…

Goodbye, Galaxies!

“I am undecided whether or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.” -Johann Heinrich Lambert One of the greatest discoveries of the 20th Century was that many of the…

Deeper into the Universe

“The cave you fear to enter holds the treasure you seek.” -Joseph Campbell Space, as you know, is mostly empty, as the typical distance between galaxies far exceeds the size of the galaxies themselves. But in a few select regions of the Universe, where the mass density is unusually above average, galaxies cluster together by…

“The human mind is not capable of grasping the Universe. We are like a little child entering a huge library. The walls are covered to the ceilings with books in many different tongues. The child knows that someone must have written these books. It does not know who or how. It does not understand the…

“A man can fail many times, but he isn’t a failure until he begins to blame somebody else.” -John Burroughs The greatest tool for astronomers of the past 20 years has, without a doubt, been the Hubble Space Telescope. Since its launch in 1990, it’s no stretch to say more scientific knowledge has come out…

“At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.” -Edwin Hubble It still boggles my mind that a scant 100 years ago, many of the…

How Far Away is the Farthest Galaxy?

“Master looks after us now, we don’t need you anymore. Leave now and never come back!” -Smeagol, LOTR You all know how to find the farthest galaxy ever, right? You take the most powerful telescope in the world, put it into space, and have it stare into the darkness for days on end. What do…
