Hace 2 días · This galaxy is a result of a merger roughly 1.3 billion years ago. NASA's Hubble Space Telescope has provided a stunning, nearly edge-on view of the lenticular galaxy NGC 4753, delivering the clearest image of this intriguing galaxy to date. Situated approximately 60 million light-years from Earth in the constellation Virgo, NGC 4753 boasts a ...
Hace 3 días · NGC 4753 was first discovered by astronomer William Herschel in 1784, and it has since been the location of two known supernova explosions. Both of those explosions were very rare Type Ia...
Hace 5 días · This image is the object's sharpest view to date, showcasing Hubble’s incredible resolving power and ability to reveal complex dust structures. NGC 4753 resides around 60 million light-years from Earth in the constellation Virgo and was first discovered by the astronomer William Herschel in 1784.
Hace 1 día · Herschel went on to discover the two largest moons of Uranus in 1787. Not to be denied, he, or possibly his son John, decided to name them after the queen and king of the fairies, Titania and Oberon, in Shakespeare’s A Mid Summer’s Night Dream. Two more moons were discovered by William Lassell in 1851.
Hace 2 días · We took into account possible observational errors, simulating realistic observations of a large sample of galaxies carried out with WEAVE at the William Herschel Telescope at different redshifts and S/N values. We measured all the available and reliable indices on the simulated spectra and on the comparison library.
Hace 2 días · Abstract. Comet 67P/Churyumov-Gerasimenko (67P) become observable for the first time in 2021 since the Rosetta rendezvous in 2014–16. Here, we present pre-perihelion polarimetric measurements of 67P from 2021 performed with the Very Large Telescope (VLT), as well as post-perihelion polarimetric measurements from 2015–16 obtained with the VLT and the William Herschel Telescope (WHT).
Hace 2 días · Sir William Herschel first observed Uranus on 13 March 1781, leading to its discovery as a planet, expanding the known boundaries of the Solar System for the first time in history and making Uranus the first planet classified as such with the aid of a telescope.
