Photo Release : Hubble monitors changing weather and seasons on Jupiter and Uranus
23 mars
Ever since its launch in 1990, the NASA/ESA Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the ever-changing atmospheres of the largely gaseous outer planets. And it’s an unblinking eye that allows Hubble’s sharpness and sensitivity to monitor a kaleidoscope (...)
Photo Release : Hubble captures movie of DART asteroid impact debris
1er mars
The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our (...)
Science Release : For The First Time Hubble Directly Measures The Mass of a Lone White Dwarf
2 février
Astronomers using the NASA/ESA Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf star – the surviving core of a burned-out sunlike star.
Science Release : Hubble Helps Discover a New Type of Planet Largely Composed of Water
Décembre 2022
Researchers have found evidence for the existence of a new type of planet they have called a “water world,” where water makes up a large fraction of the entire planet. These worlds, discovered in a planetary system 218 light-years away, are unlike any planets in our Solar (...)
Photo Release : Hubble Captures Three Faces of Evolving Supernova in Early Universe
Novembre 2022
Three different moments in a far-off supernova explosion were captured in a single snapshot by the NASA/ESA Hubble Space Telescope. The progenitor star exploded more than 11 billion years ago, when the Universe was less than a fifth of its current age of 13.8 billion (...)
Photo Release : A Cosmic Cobweb
Octobre 2022
Nowadays, all galaxies and galaxy clusters are thought to be dominated by dark matter — an elusive quantity whose nature astronomers are still working to determine. Abell 611, the glowing galaxy cluster shown in this Hubble image, is no exception. In fact, Abell 611 is a popular target for (...)
Photo Release : Webb and Hubble Capture Detailed Views of DART Debris
Septembre 2022
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
Septembre 2022
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
Juin 2022
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
Mai 2022
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 (...)
