Hubble helps find light-bending world with two suns
A distant planet orbiting two stars, found by its warping of spacetime, has been confirmed using observations from the NASA/ESA Hubble Space Telescope. The planet’s mass caused what is known as a microlensing event, where light is bent by an object’s gravitational field. The event was observed in 2007, making this the first circumbinary planet to be confirmed following detection of a microlensing event.

Astronomers observe star reborn in a flash
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 observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.

Hubble discovers rare fossil relic of early Milky Way
A fossilised remnant of the early Milky Way harbouring stars of hugely different ages has been revealed by an international team of astronomers. This stellar system resembles a globular cluster, but is like no other cluster known. It contains stars remarkably similar to the most ancient stars in the Milky Way and bridges the gap in understanding between our galaxy’s past and its present.

White dwarf lashes red dwarf with mystery ray
Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star is powering electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.

Space... the final frontier
Fifty years ago Captain Kirk and the crew of the starship Enterprise began their journey into space — the final frontier. Now, as the newest Star Trek film hits cinemas, the NASA/ESA Hubble Space Telescope is also exploring new frontiers, observing distant galaxies in the galaxy cluster Abell S1063 as part of the Frontier Fields programme.
