New Hubble view of the Lagoon Nebula

Studying giant galaxy clusters to find targets for the upcoming James Webb Space Telescope, the Hubble Space Telescope spotted what appears to be a third supernova going off in a galaxy where two others were previously seen.

Astronomers harnessing the combined power of NASA’s Hubble and Spitzer space telescopes have found the faintest object ever seen in the early universe. It existed about 400 million years after the big bang, 13.8 billion years ago. The new object is comparable in size to the Large Magellanic Cloud (LMC), a diminutive satellite galaxy of our Milky Way.

Astronomers at the University of Exeter have found helium in the atmosphere of a Jupiter-class exoplanet – a first – and sodium in the atmosphere of another, an indicator of a cloud-free sky.
