ESO's MUSE instrument grants astronomers a 3D map of Hubble's Deep Field South region

ESO's Multi Unit Spectroscopic Explorer (MUSE) instrument, which is mounted on the Very Large Telescope based in the Paranal Observatory, Chile, has been focusing in on a tiny patch in the night sky previously featured in Hubble's Deep Field South image (HDF-S). After only 27 hours of continuous observation, the cutting edge instrument has captured detailed measurements of more galaxies with more detail than ever before. Read More

Hubble captures rare image of triple Jupiter transit

NASA's Hubble Space Telescope has captured a rare image of a triple transit, as three of Jupiter's largest moons cast their shadows on the gas giant's planetary disk. The three moons captured in the image – Europa, Callisto and Io, were among the first celestial objects observed with a telescope, and were instrumental in debunking the long held belief that the Earth was at the center of the universe.

BPG image format offers JPEG quality at half the file size

French programmer Fabrice Bellard has come up with a graphics file format he believes can "replace the JPEG image format." Bellard’s BPG (Better Portable Graphics) format boasts a compelling quality advantage over JPG, particularly when images are heavily compressed. Take a look through the gallery to see a few comparison shots – the left hand side of each image shows the JPEG compressed format, the right side shows BPG at a similar file size. Read More

Handheld HeatWave device produces 3D thermal maps in real-time

Thermal imaging has proven itself to be a useful adjunct to physical testing in areas including engineering, health, and agriculture. Until now, however, conventional 3D thermal imaging use has largely been restricted due to the specialized technical knowledge required to operate it and interpret the results. To address this, Australia's CSIRO has developed a prototype tool called HeatWave that is a lightweight, high-resolution 3D scanner that is claimed to be not only easy to carry, but easy to use as well.
