Jupiter’s Colourful Palette: The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter’s clouds in this new image taken on 27 June 2019 by Hubble’s Wide Field Camera 3, when the planet was 644 million kilometres from Earth — its closest distance this year. The image features the planet’s trademark Great Red Spot and a more intense colour palette in the clouds swirling in the planet’s turbulent atmosphere than seen in previous years. The observations of Jupiter form part of the Outer Planet Atmospheres Legacy (OPAL) programme.

A Close-Up Look at Jupiter’s Dynamic Atmosphere: The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter’s clouds in this new image taken on 27 June 2019 by Hubble’s Wide Field Camera 3, when the planet was 644 million kilometres from Earth. The image features the distinct bands of roiling clouds that are characteristic of Jupiter’s atmosphere and represents a stretched-out map of the entire planet. Researchers combined several Hubble exposures to create this flat map, which excludes the polar regions (above 80 degrees latitude). These observations of Jupiter form part of the Outer Planet Atmospheres Legacy (OPAL) programme.

Artist’s Impression of Blue Stragglers: Blue straggler stars are blue, bright stars, with a higher mass than the average for a cluster, and they are expected to sink towards the centre of a star cluster over time. Those closest to the cluster core are the first to migrate inwards, with more distant blue stragglers progressively moving inwards over time.

The formation of blue stragglers: This illustration demonstrates the two ways that blue stragglers in star clusters form. The illustration on the left shows the collision model where two low-mass stars in an overcrowded environment experience a head-on collision, combining their fuel and mass to form a single hot star. The illustration on the right depicts the "vampire" model consisting of a pair of stars that undergo a transformation, with the lower-mass star draining its larger-mass companion of the hydrogen that fuels its rebirth.

Exoplanet K2-18b (Artist’s Impression): This artist’s impression shows the planet K2-18b, it’s host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapour, also indicating the presence of hydrogen and helium in the planet’s atmosphere.

Hubble’s Observation of Comet 2I/Borisov in October 2019: On 12 October 2019, the NASA/ESA Hubble Space Telescope observed Comet 2I/Borisov at a distance of approximately 420 million kilometres from Earth. The comet is believed to have arrived here from another planetary system elsewhere in our galaxy.

Orbital Path of Comet 2I/Borisov: This illustration shows the path of comet 21/Borisov through our Solar System. This visitor came from interstellar space along a hyperbolic trajectory. It is only the second known intruder to zoom through our Solar System (the interstellar object ‘Oumuamua was detected in 2017). As the graphic shows, the comet’s straight path across interstellar space is slightly deflected by the gravitational pull of our Sun. The comet is travelling so fast, at over 155 000 kilometres per hour, it will eventually leave the Solar System. The panel on the right shows the comet’s position relative to Earth when the NASA/ESA Hubble Space Telescope observed it on 12 October 2019, when it was 420 million kilometres from Earth.

Arp-Madore 2026-424: This new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face. This observation was made on 19 June 2019 in visible light by the telescope’s Advanced Camera for Surveys. Residing 704 million light-years from Earth, this system is catalogued as Arp-Madore 2026-424 (AM 2026-424) in the Arp-Madore “Catalogue of Southern Peculiar Galaxies and Associations”.

The Sunburst Arc: This image, taken with the NASA/ESA Hubble Space Telescope, shows a massive galaxy cluster, about 4.6 billion light years away. Along its borders four bright arcs are visible; these are copies of the same distant galaxy, nicknamed the Sunburst Arc. The Sunburst Arc galaxy is almost 11 billion light-years away and the light from it is being lensed into multiple images by gravitational lensing. The Sunburst Arc is among the brightest lensed galaxies known and its image is visible at least 12 times within the four arcs. Three arcs are visible in the top right of the image, the fourth arc in the lower left. The last one is partially obscured by a bright foreground star, which is located in the Milky Way.
