Science Release : Hubble Uncovers Concentration of Small Black Holes
11 février
Scientists were expecting to find an intermediate-mass black hole at the heart of the globular cluster NGC 6397, but instead they found evidence of a concentration of smaller black holes lurking there. New data from the NASA/ESA Hubble Space Telescope have led to the first measurement of the (...)
Photo Release : Hubble Pinpoints Supernova Blast
15 janvier
The NASA/ESA Hubble Space Telescope has observed the supernova remnant named 1E 0102.2-7219. Researchers are using Hubble’s imagery of the remnant object to wind back the clock on the expanding remains of this exploded star in the hope of understanding the supernova event that caused it 1700 (...)
Photo Release : When Galaxies Collide : Hubble Showcases 6 Beautiful Galaxy Mergers
7 janvier
To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key (...)
Science Release : Hubble Identifies Strange Exoplanet That Behaves Like the Long-Sought “Planet Nine”
Décembre 2020
The 11-Jupiter-mass exoplanet called HD106906 b occupies an unlikely orbit around a double star 336 light-years away and it may be offering clues to something that might be much closer to home : a hypothesized distant member of our Solar System dubbed “Planet Nine.” This is the first time that (...)
Photo Release : Hubble Captures Fading of the Stingray Nebula
Décembre 2020
Astronomers have caught a rare glimpse of a rapidly fading shroud of gas around an aging star. Archival data from the NASA/ESA Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift (...)
Science Release : New Hubble Data Explains Missing Dark Matter
Novembre 2020
New data from the NASA/ESA Hubble Space Telescope provides further evidence for tidal disruption in the galaxy NGC 1052-DF4. This result explains a previous finding that this galaxy is missing most of its dark matter. By studying the galaxy’s light and globular cluster distribution, astronomers (...)
Photo Release : Hubble Observes Spectacular Supernova Time-Lapse
Octobre 2020
The NASA/ESA’s Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away. Supernovae like this one can be used as cosmic tape measures, allowing astronomers to calculate the distance to their galaxies. Hubble captured (...)
Photo Release : Hubble Captures Crisp New Image of Jupiter and Europa
Septembre 2020
This latest image of Jupiter, taken by the NASA/ESA Hubble Space Telescope on 25 August 2020, was captured when the planet was 653 million kilometres from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a (...)
Science Release : New Hubble Data Suggests There is an Ingredient Missing from Current Dark Matter Theories
Septembre 2020
Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected (...)
Photo Release : Hubble Snaps Close-Up of Comet NEOWISE
Août 2020
The NASA/ESA Hubble Space Telescope has captured the closest images yet of the sky’s latest visitor to make the headlines, comet C/2020 F3 NEOWISE, after it passed by the Sun. The new images of the comet were taken on 8 August and feature the visitor’s coma, the fine shell that surrounds its (...)
