Can show more satellites through in-app purchases. "Star Walk: Constellation Finder" from Vito Technology Inc shows both Iridium flares and ISS passes. Satellite Tracker - (ProSat) Displays satellite paths 7 days in advance and operates offline until additional days are needed. Compass view of paths as well as 3D earth view.
The app’s Chinese name translates to “Little Red Book,” which the company claims is from the platform’s origins as a bundle of PDF shopping guides (and not a reference to the famous book ...
Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, [2] similar to the distance of M101 (NGC 5457) in the constellation Ursa Major. [5] Both were once considered to be part of the Local Group, [6] but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local ...
Beta Arietis is the star's Bayer designation.It also bears the Flamsteed designation 6 Arietis.. The traditional name, Sheratan (or Sharatan, Sheratim), [8] in full Al Sharatan, is from the Arabic الشرطان aš-šaraţān "the two signs", a reference to the star having marked the northern vernal equinox together with Gamma Arietis several thousand years ago.
Cosmos Redshift 7 (also known as COSMOS Redshift 7, Galaxy Cosmos Redshift 7, Galaxy CR7 or CR7) is a high-redshift Lyman-alpha emitter galaxy.At a redshift z = 6.6, [1] the galaxy is observed as it was about 800 million years after the Big Bang, during the epoch of reionisation. [1]
When (a similar effect) happens with a planet (we call it) an occultation (hsing wei); when the moon passes across (kuo) (the sun's path) then there is a solar eclipse (shih). [ 21 ] The later Song dynasty scientist Shen Kuo (1031–1095 CE) used the models of lunar eclipse and solar eclipse in order to prove that the celestial bodies were ...
At this great distance it takes three billion years to make one trip around the galaxy. [8] The cluster is dim in comparison to more famous globular clusters such as M13. Nonetheless, NGC 2419 is a 9th magnitude object and is readily viewed, in good sky conditions, with good quality telescopes as small as 102mm (four inches) in aperture.
NGC 2903 is an isolated barred spiral galaxy in the equatorial constellation of Leo, positioned about 1.5° due south of Lambda Leonis. [10] It was discovered by German-born astronomer William Herschel, who cataloged it on November 16, 1784.
