Across The Universe, Cont.


First, some good news (but not unexpected):
NASA will keep the Hubble Space Telescope on an additional five years. The agency awarded a sole source contract extension June 23 to the Association of Universities for Research in Astronomy for continued Hubble science operations support at the Space Telescope Science Institute in Baltimore. 
This action will extend the period of performance from July 1, 2016, through June 30, 2021. The contract value will increase by approximately $196.3 million for a total contract value of $2.03 billion.  [snip] 
After the final space shuttle servicing mission to the telescope in 2009, Hubble is better than ever. Hubble is expected to continue to provide valuable data into the 2020’s, securing its place in history as an outstanding general purpose observatory in areas ranging from our solar system to the distant universe.
Great investment, or the greatest investment ever?

COSMIC TADPOLE?

From NASA/ ESA, June 28, 2016: "This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local Universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious properties — with interesting results."  (Go to the NASA/ESA link above for those results.)

HALO,  JUPITER!

From NASA/ ESA, June 30, 2016"Jupiter, the largest planet in the Solar System, is best known for its colourful storms, the most famous being the Great Red Spot. Now astronomers have focused on another beautiful feature of the planet, using the ultraviolet capabilities of the NASA/ESA Hubble Space Telescope.

The extraordinary vivid glows shown in the new observations are known as auroras [1]. They are created when high energy particles enter a planet’s atmosphere near its magnetic poles and collide with atoms of gas. As well as producing beautiful images, this programme aims to determine how various components of Jupiter’s auroras respond to different conditions in the solar wind, a stream of charged particles ejected from the Sun."
