The Vela Junior supernova, also known as RX J0852.0-4622 or G266.2-1.2, exploded a few thousand years ago, leaving behind a glowing nebula, but scientists couldn’t answer just how far away it was and how big the explosion was. That has changed with the discovery of a still-forming star, Ve 7-27. Using the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope, astronomers have now captured the first detailed image of...

This composite image, derived from data collected by the JIRAM instrument aboard NASA’s Juno orbiter, shows the central cyclone at Jupiter’s north pole and the eight cyclones that encircle it. JIRAM collects data in infrared, and the colors in this composite represent radiant heat: the yellow (thinner) clouds are about 9 degrees Fahrenheit (minus 13 degrees Celsius) in brightness temperature and the dark red (thickest) are around minus 181 degrees Fahrenheit (83 degrees Celsius).
