The furthest galaxy cluster from Earth has been spotted some 10.2 billion light years away.  The group of galaxies, known as JKCS041 has beaten the previous record holder by around a billion light years.  It appears as it was when the Universe was only a quarter of its age and nearly six billion years before the Earth was formed.

And what a strange scene this one has created.

In a new image from NASA’s Chandra X-ray Observatory, high-energy X-rays emanating from the nebula around PSR B1509-58 have been colored blue to reveal a structure resembling a hand reaching for some eternal red cosmic light.

Spitzer Space Telescope Celebrates 5th Birthday

Spitzer Space Telescope Celebrates 5th Birthday 

 Star-forming region in the constellation Cassiopeia.

NASA’s Spitzer Space Telescope, the last of the space agency’s Great Observatories satellites to launch, celebrated its fifth birthday recently… giving me the opportunity to post this amazing multigenerational picture of star-forming region in the constellation Cassiopeia, 6,500 light-years from Earth. The photo takes in an area equivalent to four full moons and puts on show how one generation of massive stars can give birth to the next.
