The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope , but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy .
NGC 3242 (also known as the Ghost of Jupiter, Eye Nebula or Caldwell 59) is a planetary nebula located in the constellation Hydra. William Herschel discovered the nebula on February 7, 1785, and catalogued it as H IV.27.
The distance to the galaxy was previously believed to be only 2.4 Mpc (7.8 Mly). [4] However, in 2008 scientists studying images from Hubble calculated the galaxy's distance at nearly 11 million light-years away, about 4 million light-years farther than previously thought, meaning it is a member of the IC 342 group of galaxies.
WASP-121b is a hot Jupiter exoplanet with a mass about 1.16 times that of Jupiter and a radius about 1.75 times that of Jupiter. The exoplanet orbits WASP-121, its host star, every 1.27 days. [3] In 2019 a work by Hellard et al. discussed the possibility of measuring the Love number of transiting hot Jupiters using HST/STIS.
Hubble Space Telescope in the cargo bay of Discovery. STS-31 was launched on April 24, 1990 at 12:33:51 UTC (8:33:51 am EDT, local time at the launch site). A launch attempt on April 10, 1990, was scrubbed at T−4 minutes for a faulty valve in auxiliary power unit (APU) number one. The APU was eventually replaced, and the Hubble Space ...
New observations of Jupiter’s Great Red Spot captured by the Hubble Space Telescope show that the 190-year-old storm wiggles like gelatin and shape-shifts like a squeezed stress ball.
AB Aur b is detected in near-infrared wavelengths between 1.1 and 2.4 microns with SCExAO/CHARIS, at 1.1 microns with HST/NICMOS, and in unfiltered optical data with HST/STIS. The CHARIS and NICMOS data are consistent with interpreting AB Aur b as a 9 to 12 Jupiter-mass object with a radius of about 2.75 times that of Jupiter.
They found that the new measurements were in line with those previous ones from the Hubble telescope. That rules out that the former telescope had made some inaccuracy – and indicate that it is ...
