Stellar, or Stellar Lumens (XLM) is a cryptocurrency protocol which allows transactions between any pair of currencies. The Stellar protocol is supported by the nonprofit Stellar Development Foundation (though this organization does not have 501(c)(3) tax-exempt status) [2] [3] which was founded in 2014. The for profit arm, Lightyear.io, was ...
A near-infrared image of the R136 cluster. This cluster contains many of the most luminous known stars, including R136a1.Credit: ESO/VLT. This is a list of stars arranged by their absolute magnitude – their intrinsic stellar luminosity.
Stellar brightness is based on the apparent visual magnitude as perceived by the human eye, from the brightest stars of 1st magnitude to the faintest at 6th magnitude. Since the invention of the optical telescope and the documenting of binary stars and multiple star systems, stellar brightness could be expressed as either individual (separate ...
The crypto surge continues to turn heads, pushing the market capitalization of Bitcoin to over $1.2 trillion as pf Feb. 20. The last month has been relatively tough for Bitcoin (CCC:BTC-USD), but ...
I continue to educate myself about cryptocurrencies such as Stellar Lumens (CCC:XLM-USD). While my progress is slow, I’ll admit that I do find blockchain technology fascinating. Source ...
An alternative way to measure stellar luminosity is to measure the star's apparent brightness and distance. A third component needed to derive the luminosity is the degree of interstellar extinction that is present, a condition that usually arises because of gas and dust present in the interstellar medium (ISM), the Earth's atmosphere , and ...
With the top-tier cryptocurrencies moving into seemingly absurd valuations, the risk-reward profile should start favoring lower-priced, overlooked alternative cryptos like Stellar Lumens (CCC:XLM ...
