The Andromeda constellation should not be confused with Andromeda Galaxy. It is home to the pictured galaxy known as NGC 7640.

Andromeda constellation is 1 of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy. The Andromeda constellation is home to the pictured galaxy known as NGC 7640. Many different classifications are used to identify galaxies by shape and structure – NGC 7640 is a barred spiral type. These are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s center. Our home galaxy, the Milky Way, is also a barred spiral galaxy...

NASA’s Hubble Space Telescope has captured the glow of new stars in these small, ancient galaxies, called Pisces A and Pisces B. The dwarf galaxies have lived in isolation for billions of years and are just now beginning to make stars. Credit: NASA, ESA, and E. Tollerud (STScI)

Hubble has uncovered 2 tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby “big city” packed with galaxies. After being quiescent for billions of years, they are ready to party by starting a firestorm of star birth. “These Hubble images may be snapshots of what present-day dwarf galaxies may have been like at earlier epochs,” said Erik Tollerud of the Space Telescope Science Institute in Baltimore, Maryland...

Annotated image of the Spiderweb Galaxy as seen by the Hubble Space Telescope (optical) in red, the Very Large Array (radio) in green and the Atacama Large Millimeter/submillimeter Array (sub-millimetre) in blue. The red colour shows where the stars are located within this system of galaxies. The radio jet is shown in green, and the position of the dust and water are seen in blue. The water is located to the left and right of the central galaxy. The water to the right is at the position where the radio jet bends down wards. The dust is also seen in blue. The dust is located at the central galaxy and in smaller companion galaxies in its surroundings. Credit: NASA/ESA/HST/STScI/NRAO/ESO/

Astronomers have spotted glowing droplets of condensed water in the distant Spiderweb Galaxy – but not wh...

This aurora observation programme is supported by measurements made by NASA’s Juno spacecraft, currently on its way to Jupiter.
Jupiter, the largest planet in the Solar System, is best known for its colourful storms, the most famous being the Great Red Spot. Now astronomers have focused on another beautiful feature of the planet, using the ultraviolet capabilities of the Hubble. This programme will determine how various components of Jupiter’s auroras respond to different conditions in the solar wind.

This observation programme is perfectly timed as NASA’s Juno spacecraft is currently in the solar wind nea...
