IRAS 04125+2902 is a M-type star and a T Tauri variable [6] located in the Taurus Molecular Cloud, 160 parsecs (520 light-years) from Earth. [4] This young protostar has 70% of the Sun's mass, 1.45 times the Sun's radius and an effective temperature of 4,080 K (3,810 °C; 6,880 °F).
The fixed stars includes all the stars visible to the naked eye other than the Sun, as well as the faint band of the Milky Way. Due to their star-like appearance when viewed with the naked eye, the few visible individual nebulae and other deep-sky objects also are counted among the fixed stars. Approximately 6,000 stars are visible to the naked ...
The first one to address the problem of an infinite number of stars and the resulting heat in the Cosmos was Cosmas Indicopleustes, a 6th-century Greek monk from Alexandria, who states in his Topographia Christiana: "The crystal-made sky sustains the heat of the Sun, the moon, and the infinite number of stars; otherwise, it would have been full of fire, and it could melt or set on fire."
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering.
Our current view of the night sky is “deteriorating” so rapidly that a clear change will be noticeable in a generation, researchers said. Over half the stars we see now won’t be visible in ...
Several astronomers of the Middle-East began to make detailed descriptions of stars and nebulae, and would make more accurate calendars based on the movements of these stars and planets. In Europe , astronomers focused more on devices to help study the celestial objects and creating textbooks, guides, and universities to teach people more about ...
With a full moon on 5 February, experts say the darker evening hours before moonrise in the coming days will be the best bet for spotting it in the sky. How to track green comet over the week 07: ...
