In order to build a world-class telescope on a limited budget, its builders decided to utilize the design of the Hobby-Eberly Telescope
(HET) in Texas.
The find comes out of the Hobby-Eberly Telescope
Massive Galaxy Survey (MGS).
The Southern African Large Telescope (SALT) is an evolution of the Hobby-Eberly Telescope
(HET) at McDonald Observatory in Texas, USA.
To date, astronomers have discovered nearly 700 planets orbiting stars in our galaxy (with billions suspected), but they have probed the atmospheres of only a handful, using space telescopes and the largest ground-based telescopes such as the Hobby-Eberly Telescope
To determine the blazar's distance, the team then took visible-light spectra with the Hobby-Eberly Telescope
in Fort Davis, Texas.
Using the Hobby-Eberly Telescope
, the astronomers observed the planets' parent stars - called HD 240237, BD +48 738, and HD 96127 - tens of light years away from our solar system.
Low-resolution spectra taken at the Hobby-Eberly Telescope
in Texas suggest orbital motion, yielding a combined blackhole mass of at least 150 million Suns.
McArthur and her team used data from Hubble Space Telescope (HST), theiant Hobby-Eberly Telescope
, and other ground-based telescopes combined with extensive modeling to unearth a landslide of information about the planetary system surrounding the nearby star Upsilonndromedae.
Modeled after the Hobby-Eberly Telescope
at McDonald Observatory in western Texas, SALT's 10-by-11-meter primary mirror consists of 91 hexagonal segments and has an effective aperture of 10 meters.
