Photo Release : Hubble Inspects a Contorted Spiral Galaxy
27 mai
This spectacular image from the NASA/ESA Hubble Space Telescope shows the trailing arms of NGC 2276, a spiral galaxy 120 million light-years away in the constellation of Cepheus. At first glance, the delicate tracery of bright spiral arms and dark dust lanes resembles countless other spiral (...)
Photo Release : Hubble Celebrates 31st Birthday with Giant Star on the Edge of Destruction
23 avril
In celebration of the 31st anniversary of the launching of the NASA/ESA Hubble Space Telescope, astronomers aimed the celebrated observatory at one of the brightest stars seen in our galaxy to capture its beauty.
Science Release : Hubble Sees New Atmosphere Forming on a Rocky Exoplanet
11 mars
For the first time, scientists using the NASA/ESA Hubble Space Telescope have found evidence of volcanic activity reforming the atmosphere on a rocky planet around a distant star. The planet, GJ 1132 b, has a similar density, size, and age to those of (...)
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 (...)
