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).
NASA recently spotted the vibrant colors that make up the "cosmic wreath," a swarm of stars and dust on the outskirts of the Small Magellanic Cloud, one of the closest galaxies to the Milky Way ...
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 ...
A study published in 2013 [12] used the Fine Guidance Sensors of NASA's Hubble Space Telescope to measure a precise parallax (and therefore distance and luminosity) for the star. This information was used to estimate an age for the star of 14.46 ± 0.8 billion years.
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.
But the speeds found are only estimated minimums, as in reality their speeds may be larger than the speeds found by the researchers. "One of the newfound exiles is moving in the direction of the constellation Ursa Major at about 1.25 million mph with respect to the galaxy. It is 240,000 light-years away.
LHS 475 b is a terrestrial planet orbiting the star LHS 475 which is about 40.7 light years away, in the constellation of Octans. [2] [3] It was the first extrasolar planet to be confirmed by the James Webb Space Telescope. [4] It completes an orbit every 2 days and is 99% the diameter of Earth.
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 ...
