A Behind-The-Scenes Look At Building The Greatest Space Telescope Of All (Synopsis)

“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 … Read moreA Behind-The-Scenes Look At Building The Greatest Space Telescope Of All (Synopsis)

Prediction of merging stars may solve one of Hubble’s greatest mysteries (Synopsis)

“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, … Read morePrediction of merging stars may solve one of Hubble’s greatest mysteries (Synopsis)

There’s not a chance you’d mistake one for another, after a minute’s close inspection.)” -Neil Gaiman … Read moreAsk Ethan: Could you have two perfectly identical snowflakes? (Synopsis)

How the Hubble Space Telescope changed the Universe (Synopsis)

“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 … Read moreHow the Hubble Space Telescope changed the Universe (Synopsis)

We still don’t know how fast the Universe is expanding (Synopsis)

“In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever … Read moreWe still don’t know how fast the Universe is expanding (Synopsis)
