I'm glad there is a telescope like the Hubble, so many discoveries!

I agree, but think in the near future Hubble, will retire.


I know, then we'll have the James Webb telescope.

I don't think so or at least haven't heared anything about it.

It was up to be killed, instead it appears it was just underfunded enough to perhaps never get off the ground.

so when we will start to get pictures from the new telescope nustar ?

Search will start 30 days after the telescope is fully extended, which may take one week if all works well.

NuSTAR telescope was unfolded on 26 minutes. It will start calibration tests in 5 days.

Go to the NASA site and see the first high-resolution picture of a black hole, Cyg-X1.

You're right, they took it away. Go to www.jpl.nasa.gov.

Hope this helps.



NuSTAR Mission Status Report
http://www.nasa.gov/mission_pages/nustar/news/nustar20120627.html
After deploying its mast, the NuSTAR observatory began a series of checkout procedures. The procedures include measuring the alignment of all the components of the spacecraft systems that determine the pointing direction of the telescope, and bringing the X-ray digital cameras online. The team tuned up the spacecraft so that the long telescope can be pointed accurately at different locations in the sky, and they are completing the process of making the pointing direction accurate.

NuSTAR's First View of High-Energy X-ray Universe

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first snapshots of the highest energy X-rays in the cosmos, the same kind used by doctors to take pictures of your bones. NuSTAR chose a black hole in the constellation Cygnus (shown on the left) as its first target due to its brightness.

The inset image on the top right was taken with the INTEGRAL high-energy telescope; the image is 1 degree across, or twice the diameter of the moon. The bottom image shows NuSTAR's snapshot of the central part of that image. While INTEGRAL studies sources over wide swaths of sky, NuSTAR zooms into selected regions with much crisper vision.

Cygnus X-1 is a black hole that is siphoning matter from a giant companion star and spitting out high-energy X-rays. It is located in our Milky Way galaxy, about 6,000 light-years from Earth.

The NuSTAR team will use this and other "first-light" images to calibrate the pointing alignment between the spacecraft and the X-ray telescope.

Cosmic fireworks: NASA scientists released this image of a geyser of hot gas from a newborn star ricocheting off a dense area of cloud and molecular hydrogen. They have compared the picture to a classic Independence Day fireworks display.

I would love to see the above display from my backyard!


Happy fourth of July! Hubble Space Telescope captures spectacular cosmic fireworks display


Happy 4th, Everyone!

Beautiful picture Lynn:) I guess with the right telescope one could get a view like that. I have a Schmidt Cassegrain and I'm quite satisfied with it.

Your welcome :-) I had to google your telescope. Very nice!

A July 2012 study of the galaxy clusters Abell 222 and Abell 223 found they are connected by a dark matter filament, shown here. The blue shading and the yellow contours indicate the density of matter. The image on the sky is about twice as big as the full moon.
