WHL0137-LS, also known as Earendel, is a star located in the constellation of Cetus.Discovered in 2022 by the Hubble Space Telescope, it is the earliest and most distant known star, at a comoving distance of 28 billion light-years (8.6 billion parsecs).
Data collected from both the Chandra X-ray Observatory and James Webb Space Telescope were combined to depict NGC 602, a star cluster located on the outskirts of a not-so-distant galaxy some ...
Artist's conception of a white dwarf, right, accreting hydrogen from the Roche lobe of its larger companion star A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, [1] to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark ...
The Webb Space Telescope has captured the rare and fleeting phase of a star on the cusp of death. NASA released the picture Tuesday at the South by Southwest conference in Austin, Texas. The ...
[1] [13] However, more recent models of its stellar evolution have suggested revision of the star's age to 13.7 billion years [14] or 12 billion years. [5] Dubbed the "Methuselah Star" by the popular press due to its age, [15] [16] the star must have formed soon after the Big Bang [1] and is one of the oldest stars known as of 2021. [5]
Vast, a space company based in Long Beach, California, announced in 2023 plans to launch its space station, called Haven-1. The mission will be quickly followed by Vast-1, the first human ...
Such an event could theoretically accelerate a star to such high speeds that it becomes a hypervelocity star, thereby escaping the gravitational well of the entire galaxy. [5] In this respect, model calculations (from 1988) predict the supermassive black hole in the center of our Milky Way galaxy to expel one star every 100,000 years on average ...
