From soup to stars

Thanks to a new development in nuclear physics theory, scientists exploring expanding fireballs that mimic the early universe have new signs to look for as they map out the transition from primordial plasma to matter…


A life as star

A snapshot of the stellar life cycle has been captured in a new portrait from NASA’s Chandra X-ray Observatory and the Smithsonian’s Submillimeter Array (SMA). A cloud that is giving birth to stars has been…


How round can a star be? Very round.

Stars are not perfectly spherically symmetric. They are deformed by rotation and magnetic fields. Until now, the study of stellar shapes has only been possible with optical interferometry for a few of the fastest-rotating nearby…


A Born Again Star (sort of)

An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been…


The stellar Young One(s)

Showcased at the centre of this NASA/ESA Hubble Space Telescope image is an emission-line star known as IRAS 12196-6300. Located just under 2300 light-years from Earth, this star displays prominent emission lines, meaning that the…


Fountain of…. youth?

Astronomers have long wondered how the universe’s largest elliptical galaxies continue making stars long after their peak years of star birth. By combining data from NASA’s Hubble Space Telescope with observations from a suite of…


Stars Straying Away

Scientists with the Sloan Digital Sky Survey-III (SDSS) have created a new map of the Milky Way, which provides the first clear evidence that migration of stars occurs throughout our Galaxy. The study, which determined…
