Image: Hubble sees a spiral in good company
Monday, 14 June 2021 10:45
This image, taken with Hubble's Wide Field Camera 3, features the spiral galaxy NGC 4680. Two other galaxies, at the far right and bottom center of the image, flank NGC 4680. NGC 4680 enjoyed a wave of attention in 1997, as it played host to a supernova explosion known as SN 1997bp. Australian amateur astronomer Robert Evans identified the supernova and has identified an extraordinary 42 supernova explosions.
NGC 4680 is actually a rather tricky galaxy to classify. It is sometimes referred to as a spiral galaxy, but it is also sometimes classified as a lenticular galaxy. Lenticular galaxies fall somewhere in between spiral galaxies and elliptical galaxies. While NGC 4680 does have distinguishable spiral arms, they are not clearly defined, and the tip of one arm appears very diffuse.
Galaxies are not static, and their morphologies (and therefore their classifications) vary throughout their lifetimes. Spiral galaxies are thought to evolve into elliptical galaxies, most likely by merging with one another, causing them to lose their distinctive spiral structures.

Juice moves into the Large Space Simulator
Monday, 14 June 2021 07:00
The Jupiter Icy Moons Explorer (Juice) moved into the Large Space Simulator at ESTEC end May, in a two-day operation. During a month-long test campaign the spacecraft will be subject to extreme temperature cycles under vacuum to replicate the heating and cooling that the spacecraft will experience on its way to Jupiter. The Large Space Simulator is Europe's single largest vacuum chamber standing 15 m high and 10 m wide.
Once in the Jovian system Juice will make detailed observations of Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of
