Reborn Star Surprises Astronomers
«"Sakurai's object went through the first phases of [the white-dwarf re-ignition] sequence in just a few years -- 100 times faster than we expected [--] So we had to revise our models."»

First Stars seen in distant Galaxies

«UK and US astronomers have used the Spitzer Space Telescope and the Hubble Space Telescope to detect light coming from the first stars to form in some of the most distant galaxies yet seen. Speaking on Wednesday 6 April at the RAS National Astronomy Meeting in Birmingham, Dr. Andrew Bunker (University of Exeter) will discuss new evidence that the formation of the first galaxies may have got underway earlier than previously thought. This observational work using infrared images from Spitzer Space Telescope is essential, since theoretical predictions for the history of star formation in the early Universe are highly uncertain. The team, led by Bunker and graduate student Laurence Eyles (University of Exeter), used Hubble Space Telescope data to identify remote galaxies that were suitable for further study. They then analysed archived images taken at infrared wavelengths with NASAs Spitzer Space Telescope.»
