Hubble Makes Movie Of Neptune's Dynamic Atmosphere (http://www.sciencedaily.com/releases/2005/09/050902064203.htm)


New NASA Hubble Space Telescope images of the distant planet Neptune show a dynamic atmosphere and capture the fleeting orbits of its satellites. The images have been assembled into a time-lapse movie revealing the orbital motion of the satellites.

Images were taken in 14 different colored filters probing various altitudes in Neptune's deep atmosphere so that scientists can study the haze and clouds in detail.

Nice video (http://hubblesite.org/newscenter/newsdesk/archive/releases/2005/22/video/a). 8)

I think you two guys should be known as Hubble and Neptune, from now on :)

Congrats!

Oh wow, now that was GREAT! Was I the only one who spent time thinking that the best part were the moons, then another time thinking the clouds? 8)
Thanks for sharing. :)

I still have to wonder what else Hubble has been or can do.

Why no moon shots?

Early on when after it was discovered that Hubble had a big flaw, and it was then fixed, I heard a newscaster say, "....It will now be turned TOWARD EARTH as it was meant to....."

I can understand how folks would filter this info out, but I was especially alert at the time. Many times there are slips that are said once and once only.

If I remember correctly, the earth is bright enough that trying to image the surface of the planet would burn out/damage hubble's electrics. Same goes for the moon and the sun.

Hubble has shot the Moon (http://hubblesite.org/newscenter/newsdesk/archive/releases/1999/14/). It doesn't take photos of the Earth, a, because that's not its job, and, b, because it can't turn fast enough to track spots on the Earth.

However, there are spy satellites that look suspiciously like Hubble that are quite capable of taking photos of the Earth.

I stand corrected.

The HST *has* taken images of the moon: http://hubblesite.org/newscenter/newsdesk/archive/releases/1999/14/image/a

However, the instrument was not designed for lunar imaging, as that has already been done by the Lunar Orbiter series, the Apollo orbital photographs using the ITEK Panoramic Cameras, the Clementine lunar probe, etc. so there is little reason to point it at the moon. It was designed to probe into deep space to answer fundamental questions about our universe, so to point it at the moon for more than an occasional shot would be a waste of valuable telescope time and resources. Clear skies to you.

Hubble often images Earth. In fact, Earth is Hubble's the most imaged target. It must take regularly flat images for calibrating its cameras and Earth is perfect for that.

Of course, it can't take any proper images of Earth.
