Photo Release : Webb and Hubble Capture Detailed Views of DART Impact
29 septembre
Two of the great observatories, the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, have captured views of a unique experiment to smash a spacecraft into a small asteroid. NASA’s Double Asteroid Redirection Test (DART) impact observations mark the first time that (...)
Science Release : Spiralling Stars Provide a Window into the Early Universe
8 septembre
Astronomers have been bemused to find young stars spiralling into the centre of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. The outer arm of the spiral in this huge, oddly shaped stellar nursery — called NGC 346 — may be feeding star formation in (...)
Science Release : Hubble Determines Mass of Isolated Black Hole Roaming Our Milky Way
10 juin
Astronomers estimate that 100 million black holes roam among the stars in our Milky Way galaxy, but they have never conclusively identified an isolated black hole. Following six years of meticulous observations, the NASA/ESA Hubble Space Telescope has, for the first time ever, provided direct (...)
Science Release : Hubble Helps Explain Why Uranus and Neptune Are Different Colours
31 mai
Astronomers may now know why Uranus and Neptune are different colours. Using observations from the NASA/ESA Hubble Space Telescope, as well as the Gemini North telescope and the NASA Infrared Telescope Facility, researchers have developed a single atmospheric model that matches observations of (...)
Photo Release : A Dazzling Hubble Collection of Supernova Host Galaxies
19 mai
Spanning from 2003 to 2021, this collection of images from the NASA/ESA Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have (...)
Photo Release : Global Citizen Science Project Finds Over 1700 Asteroid Trails in Hubble Images
6 mai
Combining artificial intelligence with many keen human eyes, astronomers have found 1701 new asteroid trails in archival data from the NASA/ESA Hubble Space Telescope, consisting of more than 37 000 images that span two decades. The project reflects both Hubble’s value to scientists as an (...)
Science Release : Hubble observations used to answer key exoplanet questions
25 avril
Archival observations of 25 hot Jupiters by the NASA/ESA Hubble Space Telescope have been analysed by an international team of astronomers, enabling them to answer five open questions important to our understanding of exoplanet atmospheres. Amongst other findings, the team found that the (...)
Photo Release : Celebrating Hubble’s 32nd Birthday with a Galaxy Grouping
19 avril
The NASA/ESA Hubble Space Telescope is celebrating its 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called the Hickson Compact Group 40. This snapshot reflects a special moment in their lifetimes as they fall together before they (...)
Science Release : Astronomers Detect Supermassive Black Hole Precursor Lurking in Archival Hubble Data
13 avril
An international team of astronomers using archival data from the NASA/ESA Hubble Space Telescope and other space- and ground-based observatories have discovered a unique object in the distant, early Universe that is a crucial link between star-forming galaxies and the emergence of the earliest (...)
Science Release : A Record Broken : Hubble Finds the Most Distant Star Ever Seen
30 mars
The NASA/ESA Hubble Space Telescope has established an extraordinary new benchmark : detecting the light of a star that existed within the first billion years after the Universe’s birth in the Big Bang (at a redshift of 6.2) — the most distant individual star ever seen. This sets up a major (...)
