Hubble's Universe Unfiltered

While Hubble provides the highest resolution of any visible-light telescope, that resolution has a limit. There are many things in the universe that Hubble can't resolve ... in angular size. Let's ... read more

The Perplexing Physics of Imaging a Black Hole

They don't emit visible light (because of crazy gravity stuff) so you can't see them ... Fine. Angular-tiny things are really difficult to see—then how do we see the stuff around a black hole? The ... read more

Black Holes Are Real And Spectacular, And So Are Their Event Horizons

However, we can't see it all. When the most massive of ... It needs to achieve a sufficiently high resolution so that the precise details can be located at their correct angular position in space. We ... read more

Why can Hubble get detailed views of distant galaxies but not of Pluto?

How well should Hubble see either the galaxy or Pluto? To answer this question, you need to know the angular resolution of Hubble's camera. The Wide Field Camera 3 (WFC3) was used for both of these ... read more


Astronomers Characterize Wolf 1061 Planetary System

“Our observations from the Center for High Angular Resolution Astronomy interferometric array provide ... “Simply put, the planet can’t be too close or too far from its parent star,” he added. “A ... read more

Scientists use mismatch in telescopic data to get a handle on quasars and their 'tails'

This technique bests the angular resolution achieved by optical telescopes several hundredfold. This is what made radio signals so useful for resolving the structure of jets expelled by quasars. "But ... read more

Pluto: From Hubble to New Horizons

That’s understandable; people see incredible high-res Hubble pictures of planets, galaxies, nebulae … so why not Pluto? It’s a matter of what’s called angular resolution, the ability to distinguish ... read more

Hubble is a cyclops

Hubble has only one eye. It has one mirror. It can’t perceive depth, and therefore can’t see in 3-D. We see slightly different ... The human eye has an angular resolution of roughly 1 arcmin = 0.0003 ... read more
