Rejuvenated planets, as they are nicknamed, are only hypothetical. But new research from NASA’s Spitzer Space Telescope has identified one such candidate, seemingly looking billions …
NGC 1333: Stellar sparklers that last
While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time. NGC 1333 is a star cluster populated with many young stars that are less than 2 million years old – a blink of an eye in …

Since then, these billowing clouds, which extend over a few light-years, have awed scientists and the public …
An explosive quartet: Supernova ‘multiplied’ by galaxy
Whilst looking closely at a massive elliptical galaxy and its associated galaxy cluster MACS J1149+2223 — whose light took over 5 billion years to reach us — astronomers have spotted a strange and rare sight. The huge mass of the galaxy and the cluster is bending the light from a much more distant supernova behind …
Cassiopeia: The Queen
Cassiopeia is a prominent constellation in the northern hemisphere which is very easily recognised as a W or M in the night skies. In most of Continental America and all of Europe it is visible year round but becomes most spectacular in the winter months, when it is elevated to a much higher altitude. Along …
