How did this "jellyfish" galaxy get its starry tentacles?


This image of the galaxy ESO 137-001 is a combination of images from the Hubble Space Telescope
and Chandra X-ray Observatory showing the galaxy being ripped to shreds (blue streaks)
as it passes through a galaxy cluster.

A mysterious galactic "jellyfish" has been spotted swimming in deep space and dragging its sparkly tentacles through the cosmos.

Astronomers aren't sure how this galaxy ended up with its long, gassy appendages, but NASA's upcoming James Webb Space Telescope is going to investigate this cosmic cephalopod after it launches into orbit in 2021.

The "jellyfish" galaxy, named ESO 137-001, is a barred spiral galaxy much like the Milky Way. It is located about 220 million light-years from Earth in the southern constellation Triangulum Australe and is part of a cluster of galaxies known as Abell 3627. Its long tail of hot gas stretches across 260,000 light-years of space, and it's filled with newborn stars.

How many years late is Webb and how many billions over budget? And oh have they found all the
missed parts that the vibration test shook off?

In 2002, NASA awarded the $824.8 million prime contract for the NGST, now renamed the James Webb Space Telescope, to TRW. The design called for a descoped 6.1-meter (20 ft) primary mirror and a launch date of 2010.

On 27 March 2018, NASA officials announced that JWST's launch would be pushed back to May 2020 or later, and admitted that the project's costs might exceed the $8.8 billion price tag

The telescope that ate astronomy

PS NASA bow saying 2021 at a cost of 9.66 billion
